I am using plain old black out cloth and am considering upgrading to HCCV to deepen the black levels. Will I really notice much difference though?

Player?
Cable Length?

Please :D :D :D :D

I just put up the DaLite HCCV after shooting on my gray wall for a month, and I'll have to say I'm needing to warm up to it. The screen is "visible" in that it kinda shines (like a movie screen) and I notice it during action. I didn't expect that, but it really does remind me of being at the movies.

The wall was actually a similar color match to the HCCV, and I was happy with the results, so what do I get for my almost $1000?

1) Brighter, "punchier" image - definitely makes more impact than just the wall.
2) Handles ambient light better, and we watch lots of hi-def sports with the lights on so we can play cards!
3) Black background (Pro-trim/cinema contour) surrounding the picture gives a really nice effect - pro-trim worth it if you're spending that much already.
4) No more "where's your TV" questions from people when it's off :)

I got mine from Jason at AVS - best deal I could find, and supporting the sponsor to boot. Ordered on Monday, in my hands by Thursday.

I second 1-4... (no card playing though) My wife liked the frame right away as soon as we got it mounted. The empty space in the middle of the basement family room suddenly "had meaning". The difference between the perm-wall and the cinema contour is the 3 (vs. 1) inch bezel. It does a great job of framing the picture, and contains the light in the area you want it to be, with no spillage.

Of course the same effect could be had by someone carefully cutting out some strips of black velvet...

What shocked me is how "cheap" the replacement material is. I have the same frame with the HCDM .8 gain matte screen. I ordered replacment HCCV material for the frame and it was only a bit over $300 from AVS. I'll store the old material in the event I ever own another light cannon like the SE20HD.

The margins Da-Lite (or AVS, not sure where the cash goes here) on those frames must be insane. :-)

Pixel perfect just means that for each pixel sent to the unit there is one pixel on the screen. But some are cropped so instead of pixels you get black. The input image is not scaled in anyway, it's jsut chopped off. So, you get 1:1 pixel mapping but not all pixels are displayed.

It manifests as thin black bars are the top and bottom of the display.

Do this: Using a DVD player at 480i or 480p via component video center the display on the screen using something like the AVIA crosshatch ot 200TVL pattern. Note that it fills the screen.

Switch to an HTPC or other 720p source. Note the black bars at the top and bottom. The image is cropped but not scaled.

THis doesn't effect just HDMI, it effects any input that is not 480i or 480p via YPbPr and HDMI. I don't know about RGB because I don't use RGB.

IMHO it is an annoyance but not a huge deal. Movie still rock on this thing and I don;t watch test patterns for fun.

Which they'll always be. ;)

I'm a first time projector owner and find that for a relatively low cost, I got into the AE700 front projection system with picture quality that is well worth what I paid for it.

I don't intend to use it all the time, just for material that is appropriate for a 104" screen. (no Howard Stearn)

It sure was nice to get a new toy that works right.:p :p :p

this is the second time i've heard someone say something as crazy as this.

are you saying that the projector masks 30 lines of it's panel? (this is what i asked last time with no response).

it's not like i'm eager to count lines, so if you have some inside information, please do share.

After having 2 AE700 at my home. I can say there is NO difference with VB on these two units. I can tweak away all VB, and the only thing that is left is FPN. The numbers on flicker tweak was different though. But both units were set to high from factory. And why is that? both units had to be reduced to -5 from all 6 rgb settings.

Loving my Panny AE700 and about to pick up an xbox.

I've searched this thread and can't seem to find the info I need. It does seem, though, that most are hooking the xbox up to the projector via component.

1. Is there another option for connecting the xbox to the projector other than component?

2. If so, which will give the best pq?

3. Will the games fill a widescreen 16:9?

I seem to remember reading something about another option to component hookup but heck if I can find it.

Thanks,
Bob

1. There are vga converters out there for a decent price. I know Lik-Sang.com has some. Not sure about other places you could buy from.

2. Not sure on this one. There probably won't be much of a difference. I think most people buy it to hook it up to their computer screens for a better picture.

3. The Xbox has a 16:9 option. And I believe most, if not all games, are 16:9. Games that aren't will still fill up the screen.

You can get a de-interlacer VGA box, but this is your worst option. With the cheap deinterlacer, you are probably better off using yr projector to do the deinterlacing through s-video or composite.

The better solutions are
www.x2vga.com
www.vdigi.com

Both offer true transcoding capabilities from HDTV to VGA.

X2VGA is easier to hook up and is powered by the XBox AV Pack.

VD-Z3 is a generic component to VGA transcoder, and needs to be powered from an external power source. In addition, it needs a HD AV cable to provide component connections from the XBox to the transcoder (cable is supplied).

I agree. I tried 480i last night and it is noticeably better than 480p with the 700. I find it smoother, more filmlike and like the picture just has more life to it. It's not necessarily sharper, just nicer. The scaler in the 700 must be better than what's in my DVD player (?)

Is anyone else running 480i into the 700, and if so, which DVD players would be recommended for under $200-300 (even old used ones)? Sorry if this is getting too off-topic, but I think a fair number of 700 owners and prospective owners would appreciate this insight.

Got my projector! Just wondering (in Australia) what sort of screen I should be looking for.

Looked at Grandview for around $400 16:9 100" or thereabouts, but heard the gain on these is high, like 2.0.

What sort of gain would work best with a unit like this and perhaps what kind of screen should I be looking at, within a reasonable budget, preferably under A$500.

Thanks.

Rudeross, I sat on the fence for a year and a half before jumping off. I tend to be a perfectionist with my hobbies. Is the AE700 perfect? No, but for under 2k it is excellent. There seems to be endless tweaking possibilities. HD Monday night football looks great too :)

Exodius, I had VB quite noticable too but I tweaked it away. There is still a little FPN on panning shots of the sky or snow covered mountains. Has the "dirty" look but very brief and subtle. I only notice because I am looking hard for these things.

TvTed, the HDMI cable is 15ft and under $15 makes it a great low budget deal. Worth trying out before plunking down the big money :)

NavinJohnson,

I also prefer the 480i to the 480p. It just looks better. I've tried "basic" Denon, Toshiba and JVC DVD players. Currently I'm using the JVC, less than $140 player and it works great. I'm toying with the idea of one of the upconverted DVD players tho'.

For members with a screen................
I'm using a vutec 110" screen. According to PCentral it wasn't the best of the bunch. What would anyone recommend for a screen with more "punch?" The dalite HCCV? Draper also has a screen that's nice.
Just wondering.

I hope it's OK to post this here, but does anyone know of a place to see/purchase the 700 in the New York area? B&H is usually the best bet, but right now they're only carrying the 700 as a special order (3-4 weeks). They have the Z3, but I really want to evaluate the 700 before considering that option.

Thanks.

I think what he meant was to use a PC VGA card to send out 1280x720 to create a 1:1 mapping.

If you use a DVD player than can rescale to 720p, you could try one of those transcoder boxes.
www.vdigi.com
for instance, but I don't see how you would be better off than using component directly to the projector.

Whorton,

Do yourself a favor - buy the Z3.

Vertical banding, PAB scan lines, Bizarre white flashes while watching material over HDMI, and multiple reports (though this is a problem I haven't had luckily.... Yet...) of convergence issues has me saying to myself over and over, "Should have bought the Z3.. damn damn damndmnadmnaddmnamndnamdanmdamndmndamndamndmnad!"

I owned a Z2 and loved it! Granted, didn't have the contrast that the 700 does... But the Z3 does!

Good luck!

As far as 480p RGB/VGA goes......Has anyone used an iScan Plus/Pro or Ultra with the AE700? If so, how does it look? I myself have an Ultra and am curious as to how it would work with the 700, letting the 700 scale.

djbluemax1
12-08-04, 10:29 PM
BTW, just wondering how many people are curious enough to know the limits of the LCD panels' response time and how it affects the picture?

Haven't been able to take any measurements of the response time but if you're interested, 'Chronicles of Riddick' seems to be a movie that can test the limits of the 700's response time especially all the stroboscopic cinematography both in the arrest attempt in Imam's house and the attack of the Necromongers. If you still aren't sure what I'm talking about, here's a specific scene to take a look at:

When the Necromongers attack, at 00:25:26 in the scene where Imam is trying to lead his family to safety, they get separated and Riddick pops up, pulling him around a corner to hide, watch Imam's head and the background wall as he's yanked around the corner and note the lag in response time causing ghosting and multiple imaging from the movement.

***This is not any sort of derogatory comment with regards to the projector's performance. As the header says, it is merely something of interest for those interested. It was interesting to me in comparison to PC LCD monitors. Tried an LCD monitor with a stated 25ms response time and found it unbearable. Even doing things liking surfing this forum and scrolling the page caused ghosting between the blue and gray panels. Dell's 2001FP looks much better in terms of reduced response time and ghosting compared to the 25ms monitor.

New update on the 'white flash' issue
Can't believe I didn't think about trying this before. AE700U connected to Denon 2910 via Monster HDMI-HDMI cable.

NO DVD playing. It was just the default gray screen (selectable on the Denon player between blue, gray or Denon logo when nothing is playing or no DVD is inserted) and as I was doing something else after finishing a movie and before starting another one, took about 45 minutes (delay was longer than expected) and whaddya know? WHITE FLASH!!! I doubt the Faroudja chip is processing anything when it's just showing the default screen and nothing is playing.

This may support the HDCP/white flash theory, since HTPC's don't output HDCP encryption.

zxl8r,

I'm no troll. In fact, I generally just peruze the forum to learn more from others. This is why you don't see many posts from me. I've been here for several years, and about six months ago I decided to register.

As far as "proving I own one," well - I have nothing to prove to you, and furthermore, I believe it would be petty to try.

I can understand your hatred towards my post since you have an ae700. But please, don't take it personally. Quite simply - the projector isn't for me. Unfortunately I've gone 1 hour over the 15 hour return policy my vendor has.

To the fellow who posted this brilliant nugget, "hehe... too bad they have the exact same panels.." Yes, they do! Great observation - but they don't have the same HDCP circuitry (which is what is believed to cause the flashes), nor do they have ANY of the same internals other than the panels.

It is of my opinion that when talking about $2K or less projectors, that the Z3 is the superior unit. This is evidenced by the fact that I thoroughly enjoyed my Z2 and my neighbor has a Z3 that I feel is superior to my projector.

Again, I'm not trolling, I'm not trying to get anyone to "bite." I simply stated my opinion when someone asked for guidance.

If you are pleased with your projector [speaking specifically to the ae700 owners] then I'm pleased as punch for you! :)

Well the reason I asked the original question was because someone posted about the pixel cropping on all inputs except the VGA one. So I figured that using VGA (vs component) would fix that problem, but I didn't know you needed a trascoder box to do it.

I previously had a Z2 and now I have the AE700

I thought I would list a few pros and cons for Each projector.

Sanyo Z2. Pros
1. 1x1 pixel mapping.
2. Easy Lens shift
3. better warranty (3 years)

Cons: 1. Much lower light output
2. VB problem
3. Not enough contrast
4. Dust problem bad filter.



Panasonic AE 700

Pros: 1 Very bright
2. Good contrast
3. Much less of a VB problem for me
4. Great adjustments.
5. Long Bulb life

Cons: 1. Lens Shift difficult to use.
2. Cropping problems
3. Some have white flashes (no problem for me)

I have not tried the Z3 and I am sure it is a fine projector. The reason
why I went for the AE700 was for the contrast. It really makes a big
difference for me. It is not a perfect projector but for about $2000 is
is very good. I do wish that Panasonic would address the cropping and
other issues reported.

In comparison to most movie theatres my picture is great. Most theatres
cut off a large part of the image with aperture plates. It is a pleasure to
see no scratches or dirt on the image. I am sure if I spent more time on
tweaks I could get an even better picture. I am, however, too busy enjoying HD programs and movies.

The only cropping is on the HDMI input. There is no cropping on other inputs on my machine.

Doesn't 1080i over component crop both sides and top/bottom? I believe that's what an earlier poster observed.

I had the chance to see an AE700 in a shop with ambient light spilling from outside the mall and the Z3 in a completely dark demo room.

To be honest, the Z3 looked like a brighter and more contrasty version of the Z2.

The AE700 on the other hand looks far more dynamic and 3D-ish. The contrast looked really really good next to the 4805 displaying a smaller image right next to the AE700. (as I mentioned, the AE700 wasn't shown in an ideal environment). In fact, despite displaying a smaller screen, pixellation on the 4805 looked pretty bad.

I didn't see any VB on the AE700 but then it was being booted up from cold (not from standby).

I did notice what looked like high density static (like when you don't get a signal off yr TV in the days before they blanked out the screen in blue) off a Pioneer 939(?) player. But they twiddled with the player and the static went away. The guys in the shop suspected it could have been due to the length and quality of the HDMI cable. I have no idea if it will return since I only played with the set for about half an hour but it didn't return. Video quality from the HDMI connection seemed far more punchy than component.

But the overall image quality convinced me to get the AE700 over the Z3. The fact that the Z3 was priced about the same as the HS50 was also a big minus in my book (list is abt US$1k more!!)

Not on my machine. 2-3% cropping is normal for most tvs. I do not see any, but I guess I will have to throw up a test image on my htpc. I know for sure it does not crop on 480p.

wiredman's post:
For members with a screen................
I'm using a vutec 110" screen. According to PCentral it wasn't the best of the bunch. What would anyone recommend for a screen with more "punch?" The dalite HCCV? Draper also has a screen that's nice.
Just wondering.
____________________________________________________________

I'm also using a 123"diagonal Vutec Silverstar and love it. Even in low lamp cinema 1, cinema 3 or natural mode, it looks plenty "punchy" to me in my room(light controlled, dark walls and ceiling) and quite decent in daylight in cinema 2 ,normal, and video modes-- dynamic is just too far off kilter for me to enjoy.

I don't always agree with what any reviewer says. In my opinion Projector Central was right about the Panny, but wrong about the Silverstar. BTW, Tryg, who started some of the great threads on the screen forum, as well as the sponsors of this forum(the AVS science folks) use the Silverstar in their own theaters...

It manifests as thin black bars are the top and bottom of the display.

Do this: Using a DVD player at 480i or 480p via component video center the display on the screen using something like the AVIA crosshatch ot 200TVL pattern. Note that it fills the screen.

Switch to an HTPC or other 720p source. Note the black bars at the top and bottom. The image is cropped but not scaled.

THis doesn't effect just HDMI, it effects any input that is not 480i or 480p via YPbPr and HDMI. I don't know about RGB because I don't use RGB.

IMHO it is an annoyance but not a huge deal. Movie still rock on this thing and I don;t watch test patterns for fun.

Panasonic AE 700

Pros: 1 Very bright
2. Good contrast
3. Much less of a VB problem for me

iclaudius,
Thanks for the info. I'm only using a brite white 110" 16x9 vutec screen. I don't think the brite white is 1.0 gain? What made you go for the SilverStar? It would be a big jump $$$ but I want more "punch/brightness" when any lights come on. My room is completely light contolled but behind the 700 (17' back) area is a bar / game area. When the lights are somewhat on 20' back it starts to wash out the pic. Some people like to play pool while the others watch HD/DVD. I'm guessing the SilverStar would be the way to go? OR for the same money buy a 2000 lumen "extra" pj and set it up for sporting events? AVS'ers use the SilverStar in their rooms...........I just thought it might be a little too bright.

I had seen it once every few hours via the 4200HD, but not without this equipment.

I had an interesting experience today..

5 hours into the globe, the PJ did what I can best describe as "track out", just like tracking on old VCRs. The screen went into three, and pale and all fuzzy and stuff.

It was hot indoors, the unit was new, and the globe was on dynamic (my bad). Anyway, is this something to be concerned about? Or is it a hopeful one-off.

Since then, 3 hours or so, it has been fine again.

The reported cropping on the digital (HDMI) input for HTPC is a real bummer and a flaw in what
otherwise would appear to be an amazing unit.

I see what is a likely answer/confirmation of why one can't get the cropping to go away and still
get 1:1. If you look at an article that explains how they achieved 1:1 digitally through DVI on
the AE500, for a Momitsu DVD player...

(I cant post links yet by the engine - so please add dot html at the end and translate the angle
bracket sections..)

home.clear.net.nz<SLASH>pages<SLASH>adbarr<SLASH>AE500

...you will see that they needed to switch the mode to 'WIDE720' and not '750p' or '750'. They did
this, as already mentioned on this thread, by switching from the 'EDID' to the 'EDID2' option setting.
(something now stated by someone here as not available on the AE700.)

Now if you download both the AE500 and AE700 product manuals with google, and compare
the signal modes tables in the appendixes, you can see very clearly that the AE500 used to support
a much wider range of modes through the digital input (DVI) than does the AE700 through HDMI,
including the desired 'WIDE720' mode which I believe is the mode one is looking for so that
HTPC won't have any "cropping" at 1:1. That mode is NOW only available on the PC analog input,
when it used to be available on the AE500 for BOTH the PC and DVI input. This is also true of many
other modes. Hence with this new unit, we actually lost much featurewise in terms of mode-use
for the digital hookup. That's something to clearly point to when calling up Panasonic and
complaining that this unit essentially lost feature/mode capability in the switch over from DVI to HDMI.

I also found this article which might also be of interest...

(please add dot HTM at the end and translate the angle bracket sections..)

w w w <DOT> dvd-a.dk<SLASH>start.php?page=tests<SLASH>denon_dvd-2900_uk2

which claims why the cropping is there for DVD players, and that HTPC is actually
capable of showing more of the picture that is stored on the disc than DVD players.

I was all ready to buy this projector after 2 days of reading this thread, but now I am completely
bummed. 15 pixels (on the top and 15 on the bottom of the screen) on an HTPC as reported is the
same height as a typical window's title bar. Losing that real estate in normal computer screens
or probably more importantly in games could have an meaningful effect as important status
(or status bar) information could easily be in that area.

I think the only possible solution to this is if enough people call Panasonic and complain that we
lost an important feature for HTPC (which is a very hot emerging application), that maybe they
might issue some kind of fix.

Just as a side note, when I had previously called and waited for tech support I finally got passed
a special phone number instead for Panasonic Industrial Video (1800-524-1448). The guy there
wasn't too knowledgeable, so he gave me another number to a local guy in my state and then
another guy in a different state - who finally happened to know a more informed tech person
at panasonic, and finally I spoke with him. It took a little persistence but considering the
extraordinary efforts that go on here dissecting these projectors, I would think its also
an equally important endeavor to spend the time to also increase ties/relations to the right
people at the manufacturers, so that when issues are found we have a clear channel to get
them addressed/solved.

So I think its a numbers game. The more people they hear from about this issue the
better chance of solving it. Once again pointing to the comparison of those resolution
charts would seem to be the black and white for this issue.

BTW, do people here think that this flaw, which has no tweak, is pain enough not to
purchase it - I will be using it practically 100% for HTPC. Is the analog VGA input so good
that its almost a non-issue?? (I mean it seems painful to buy a brand new model $2k pj
and not use a digital input.)

Thanks, Greg.

Regarding the peek-a-boo scan lines during vertical movement on 480p, I noticed sometimes I see it and at other times I don't.

Then last night, I saw it on my rear projection Sony TV. So to some extent, it appears to be source related.

Pixel cropping (on analog HD feeds as well), white flashes, VB and fan noise have given me a reason to look elsewhere. Pure digital paths are supposed to improve the image.

I'm not reading about these problems with the Z3, for instance.

liowik,


I am using HDMI for my HTPC hooked up to my 700. There is some cropping but not nearly as extreme as you pointed out.

I am running xp at 1280x720 and the only crop I have goes to the bottom of the letters or quick launches on the task bar. It does not hide anything at all except some of the colored area on the bottom of the taskbar.

There is probably 3-4 pixels I am missing on the top and bottom. There is no way it is as drastic as you pointed out unless you setup the projector wrong. I need to take some pictures to prove to you what i am talking about. I play alot of computer games, but none are affected whatsoever.

liowik
12-10-04, 11:42 AM
Thanks zxlr8 and BubbyWilly,

The 15 pixels was from what I had read from other posts concerning this issue.
Posters additionaly seemed to also derive this from the difference between 750 mode and 720 (30 /2 = 15). I have been researching this for purchase so I can't test this myself. 3-4 pixels, if that is correct, would be a COMPLETELY different story and I would be super happy to hear that, assuming you are in fact getting a true 1:1.

I would love to see some kind of screen pics. Or, if that would take some delay in posting, even if you could just do a vanilla computer print screen and then draw some bands above and below in XP paint that accurately indicate the cut offs, or even a simple accurate count out of the number of "cropped" pixels pixels for confirmation. Then I can get a clear idea of what this really amounts too.

Also are you simply running just vanilla 1280x720 or are you using any powerstrip or other software specially (if so what are those settings)?
Also not that this should make any difference but what graphics card are you using?

The VB has the flicker tweek, and the white flashing doesn't seem to occur as much with HTPC, fan noise seems to be, more so than not, across the board a non issue, with only few noted exceptions, so this was the last hold over in my decision.

Thanks Alot!

Hey guys,

I haven't been participating in this thread recently because I feel like the owners have much more to offer than I do. I've kept an eye on it nevertheless. However, I am not as informed as I wish I were.

Can someone give me the detailed summary on the white flash issue? I'd be interesed to hear:

1. Does it affect all owners?
2. How often does it occur?
3. What inputs of the device are affected?
4. What tweaks have been confirmed to reduce or eliminate it (if any).
5. What is the general forum opinion. Do people regret the purchase because of them? Does it ruin a movie experience?
6. How long does a flash last?

A similar summary re: overscan/cropping would also be appreciated.

I am down to a point where I think the white flashes on this unit and the dimmer image on the HS51 are my two major concerns. I'd just like to see what I can learn about these.

Thanks for any help that anyone can offer.

No projector is perfect yet, especially one priced at about $2000. The issues Reaper questions in the above thread are problems for some of us.
I have not experienced the white flash but I have seen the cropping and
VB issues. I do not regret my purchase at all. The AE700 is a great projector. Many of us would like to solve the problems mentioned. Don't become obsessive compusive. Get one and start to enjoy movies and

I've never seen a 'white flash' in about 80 hrs. However, everything (DVD, HD, PC) is feed via RGBHV. The inability to get pixel-perfect, un-cropped data over HDMI prevents me from using that. (And, once the PLL is properly adjusted in the PJ, I can't tell any difference between HDMI and RGBHV anyway.)

I am getting a TOTAL of 14 lines of vertical resolution cropped.
I can play with whether I choose to crop off the top 14 OR the bottom 14 or something in between by using the Position adjustment on the remote.

I personally have chosen to crop 7 lines off the top and 7 lines off the bottom. That way I can still access all functions on the task bar and the title bar even though they are a bit compromised.

I think it would be good if we all made an accurate count of how many pixels are being cropped in each of our devices. Does it really vary, or is there a consistent number?

Realistically, this problem only is visible when I have my HTPC desktop visible. It bugs me but really doesn't affect movie watching or HDTV watching. In fact, if I get Meedio working or some other front end for the HTPC, it would not be noticeable because the UI on those HTPC front ends don't have information at the very top and bottom. It really comes down to the desktop because the title and task bar are right at the vertical extremes of the display.

Can I live with this?
I don't know. It very much concerns me that Panasonic is knowing lying about the capabilities of the projector. Almost 2% of the screen area is not visible. You are really getting a 1280x706 display NOT 1280x720. That is arguably the equivalent of 17,920 dead pixels on the display. I think Panasonic would sit up and take notice if every projector had over 17,000 dead pixels. According to Projector Point, Panasonic knows that this projector can't display all 720 vertical lines so they claim there is nothing wrong with my projector, they all do it.
BULL tweeties to that IMHO.

I agree that we need to make noise about this issue to Panasonic. I have engaged one regional service manager from Panasonic who claims to understand and be on my side. He has escalated the issue within Panasonic but hasn't heard anything back yet.
Keep sending those cards and letters to Panasonic and share any info you get.

12-10-04, 01:57 PM
Hey reaper,

Here are some answers to some of your Q's

1) No, there are some owners who report never having seen a white flash
2) For me, it averages about once or twice per 2-hour movie. Sometimes I don't see it for an entire movie, sometimes I see it 4-5 times in one movie. No, the flashes are not related to layer changes. They don't happen at the same point in the same movie if you rewatch a movie or rewatch a scene that just flashed. Also, in my white flash update post, I got a flash with the projector on but NO DVD playing at the time. Projector had the default blank gray screen that my Denon 2910 outputs when there is no DVD playing. ***People with non-Denon players have also seen flashes
3) HDMI seems to be the most common culprit. I still haven't tested it with component or VGA but at the very least, some have reported flashes over component.
4) There has been only one tweak so far that claims to have eliminated flashes, but the users have admitted that the flashes they get might be different from what others have been experiencing. Also, the tweak (posted by Aussie Bob: change WideScreenSelect from Auto to Manual) only concerns the playing of PAL material, not NTSC.
5) The answer to this question is a very personal one. you would have to draw your own opinions from the info here including the asnwer to the question below.
6) A flash is very brief. Possibly lasting only a quarter of a second. Definitely not a full second and I doubt it's even half a second long but when it does flash, pretty much the entire screen flashes and the flash is white with colored specks. Pretty much the same loss of sync/signal white-color-speckeld screen that flashes when I use the DVD player's remote to change an output format, i.e. when changing from 720p to 1080i, when changing the aspect ratio for anamorphic and non-anamorphic DVDs etc.

The flash screen during movie watching is briefer though, however it is just as bright. In fact, in my darkened room, the flash is bright enough that it lights the room quite well and makes it noticeable even if you're not looking at the screen. The first time I noted how well it lit the room, I was looking for a drink that I has set down nearby and looking away from the screen. There was a flash that pretty much lit up the whole room to my dark adjusted eyes and knowing the scene, I knew it wasn't from the movie.

For me personally, it is very annoying. Although brief, when it happens, it does take me out of the movie, initially with a "WTF was that?!" reaction, but now that I'm aware that it happens, these days, it's a "Damn it" reaction. With about 140 hrs on the projector, honestly speaking, if I could return it without penalty, I probably would until and unless Panasonic finds a way to fix this.

As mentioned in Q #5 though, it's really up to you personally. Other owners have commented that they can accept the flashes and don't consider it much of a problem. Would they still be willing to live with it if they had the option of returning the projector and receiving a full refund? Who knows?

I am also using a HTPC. I would estimate missing around 30 pixels vert in total. Using the latest nvidia drivers the display is recognized as an AE700. The cropping bugs me but it really doesnt effect using the windows desktop.

BUT i would like to know what others are doing about fitting the desktop to a 16:9 screen given the vert is cropped. I get a thin black bar top n bottom and this is what i find most irritating not the fact i am losing pixels.

Do others just zoom the image to fill the vert and end up displaying on the black frame a bit for the horizontal ?

12-10-04, 05:10 PM
Durabolin, 30 pixels is a big difference from the 14 posted by zxlr8. Are you using the HDMI digital input and at 1280x720 at 1:1? Also can you please confirm 30 exactly pixels. That figure when split to 15 is enough to create black bands that completely cover a title bar of a window or the status area of a window.

BTW there were instructions about how to reach 1:1 with 1280x720p posted in the tweak thread I believe.

zxlr8
12-10-04, 05:27 PM
I will take a picture tonight and end the assumptions. There are definitely missing pixels, but only a few on each top and bottom. I will try to get a couple of other pics in there as well. Far Cry at 1280x720 on the 700 is the best picture I have seen of anything. REALLY, REALLY INCREDIBLE. I am running a 9800 pro by the way.

Durabolin
12-10-04, 05:37 PM
I am at 1:1 1280x720p. I havent counted exactly how many pixels coz frankly it doesnt matter. I cant fix it so why bother ? I do know it doesnt really affect using the desktop. To give you a rough idea i would estimate if i shifted the image with the picture shift so all the cropping is at the top you will lose maybe 50% of the windows start icon (note i have the tasbar vertically placed on the left side).

I am also telling you that not filling a 16:9 screen perfectly will bug you a lot more than having some cropping of the image. Trust me :) Although of course the 2 are intrinsically tied together. Remember with most movies being at around 2.35:1 you are totally unaware of the vert cropping. be thankful you dont get horizontal cropping like the hs51 coz how the heck could you avoid noticing that ?

I, as others have said, shifted the image so the cropping was equally balanced between top n bottom. I lose some of the start icon and a little of the time display.

I will also add that using vga solves all these problems and you get a perfectly filled 16:9 screen. With a quality vga cable there really isnt much difference between hdmi and vga. I havent compared the 2 closely enough to draw any insightful conclusions but i do know that vga looks damm good and you certainly dont feel that you are missing out on PQ.

Thanks for the feedback - measuring 60% of that Start Menu item in the way you have it configured measures roughly 14-15 pixels - so perhaps it is very close to what zxlr8 has. I would be very surprised if this "cropping" came out to be different on different people's machines - its almost certainly just a static aspect of the pj when its in mode 750p. Can anyone confirm that when the pj has no cropping using the VGA connector that the pj reads in mode WIDE720?
(Because I think thats the mode that we would really want.)
(BTW, is cropping the correct term here? It seems more like its just masking black area upon what would otherwise be a perfect picture. "Cropping" sounds more like maybe its cutting it out of the picture and possibly causing some people confusion that its overscan and not 1:1. )

I am still looking forward to that pic zxlr8 - thanks, although I am starting to get more concerned now over the flashing issue. Sorry if this question was already asked but is it not the case that this flashing problem has not been seen, or seen very infrequently when using HTPC HDMI?

Thanks.

yup VGA is wide720 and has no masking/cropping at all. It even has an auto fit feature where it adjusts various pixel clock settings. It really is plug n play with one press of a button.

Radio Frequency Interference filters. Also known as EMI (ElectroMagnetic Interference) filters. These are passive L/C filters placed on the analog outputs to shunt some of the high frequency components and keep them off the cable in a effort for the product to meet EMC (ElectroMagnetic Compliance) regulations. They are usually a pi, or T configuration and are on the R,G, and B lines as well as the syncs. Unfortunately, they usually also shunt some of the high frequency components that are a valid part of the signal and produce some softening at higher resolutions and refresh rates so are often removed by more anal purists. The capacitors (C) are removed and the inductors (L) are shorted.

The topology, placement and layout vary with different video cards. I could document the mod for a Radeon AIW 9800 Pro for anyone interested showing which caps to remove and which inductors to short.

You will need to know which end of a soldering iron to hold.

Is the difference between DVDs over HDMI and component negligible? Or at least not a big enough difference to warrant the purchase of an upconverting player? My 700 is being shipped to me now and I was thinking about going with a Denon2910. But with the cropping and white flash issues over HDMI, I'm thinking it might not be worth it.

VB-FLICKER ADJUST-POWER OFF

I am trying to research on this power off issue. I have found that when i power off, the flicker screens does not flicker at all. It is like the projector is already warmed up, when you are doing a coldstart. So i can now see that the VB is gone when using the power off.

Concerning the perfect WIDE720 mode (with no "cropping") - Well that really confirms it then. WIDE720 mode was available to the DVI input on the AE500, but with the AE700, Panasonic isn't allowing us access to it with HDMI - even though its there for VGA. The projector is perfectly capable of producing all 720 lines, so if they only made the WIDE720 available again to the digital input - like it was in the AE500 everything would be perfect.

Can anyone post a picture (screenshot) with pana 700 ouputting over HDMI so I can see the cropping to see whether it would bother me.

I'd actually like to see some screen shots of the same image using both the HDMI and VGA ports to see if there is any difference in picture quality. Also can someone post some screen shots of their desktop. I might be using the projector as my main monitor if all is well with text sharpness and picture clarity. Thanks

Just thinking out loud here ...


But, the majority of white flashes seem to have occurred with HDMI.

It has also been out forward that maybe HDCP is the culprit, as users running component video don't seem to be having the same problems.

So I was wondering, does all video sent via HDMI also have HDCP enabled ?

If not, could we get someone to try viewing content with HDCP and without to see if they notice the absence/presence of flashes ??

Just a thought ...:)

HDCP * HDMI go together. HDMI is the physical connector and specs for the signal levels, while HDCP is the Software encryption standard. It seems like Panasonic just needs to update the firmware so that if the HDCP protocol gets messed up momentarily they don't immediately drop the picture (which is probably what causes these momentary flashes). Seems like the FW could easily check to make sure HDCP is gone for at least 1-2 seconds before doing anything with blanking out the picture.

amrod,

Save your money. Panasonic projector bulbs seem to last quite a while. 1000,2000,3000 hours or longer is very possible, and even likely. Why lock up $500 or $600 CAD on a bulb you may not use for at least a year or longer. Save your money and buy one when you need it.

Regarding whether newer AE700's still have VB, I left mine on standby for 3 nights, and yes now I see VB on my November 2004 build date AE700. The flicker tweak mostly eliminates it. Mostly. Hopefully leaving it all the way off tonight will remove the VB again.

Hmmm, now I notice another flaw. Horizontal banding. On a dark gray Windows desktop, if I move around a window with dark and light areas (like this AVSForum screen), I can easily see horizontal bands. Dark bars in the window continue across the desktop to the left edge of the screen. I guess my video card is the likely culprit, right? (Radeon 9600 Pro, VGA output.)

Other owners have commented that they can accept the flashes and don't consider it much of a problem. Would they still be willing to live with it if they had the option of returning the projector and receiving a full refund? Who knows?
Reaper - The white flashes appear to be a digital artifact associated with handshaking between the projector and source device (i.e. DVD player or cable box). They don't seem to occur on the analog connections (component or RGB inputs). Despite theoretical advantages for an all-digital signal, the quality for component also appears to be comparable (i.e., very similar to HDMI).

I have been experimenting with the combination of a Sony 975s DVD player, a laptop temporarily serving as a homebrew HTPC (based on recommendations by TraderGordo), and a TIVO fed by cable. I have not encountered a white flash with HTPC. I have experienced 4 white flashes in 100 hours of viewing with the 975s DVD player.

For this configuration, the flashes are more of a momentary flicker when the digital handshaking drops synch for an instant. As djbluemax1 notes, the extent to which is an issue is really a matter of a personal reaction. I have found the transient flicker to be minor -- noticeable, like the dot that appears in the upper righthand corner to signal a reel-change at the local cinema, but less distracting than a loud conversation by someone in the next row, or a cell phone ringing.

Even though the HTPC doesn't have white flashes, I've decided to keep the stand-alone DVD player. The flashes are a minor issue and I like the feature set of the DVD player. (Also, as my wife notes, it continues to operate reliably even when I'm tinkering with the HTPC, which appears to be evolving into on-going "hobby" status). If the flashes were a concern with the DVD player, I could shift over to component, but like just having a single cable for the digital input.

As for returning it if Panasonic offered a full refund, no way! There's nothing else that comes close to the price / performance ratio for this installation. The combination of the long-throw lens and lens shift allows it to be tucked away in a corner bookshelf at the back of the living room, so it's unobtrusive when not in use. It's bright enough to use as a large-screen TV in the daytime (using the "Normal" mode), and it is terrific for movies at night (or with the blinds closed) in the Cinema mode. The fan is quiet and unobtrusive, allowing us to enjoy a convenient, easy-to-use system with a range of media. It has quickly become an integral part of our day-to-day lifestyle, the essence of home theater. Panasonic would have to pry it from my cold hands ... <grin>

Wiredman, I chose the silverstar based on Tryg's comparisons and Jason Turk's recommendation. I don't planning on changing screens, but the AE700 won't be my last projector---I hope. If I have lights on at the back of the room some 22 feet from the screen-- the picture's just fine and there isn't any wash out. With any screen, save perhaps the unyet released Sony, direct sunlight on the screen isn't going to produce a picture. Some lights on in the room, however, are ok as is some sunlight anywhere but directly on the screen.
_________

Reaper, I've read your posts on both this forum and the sony hs51 because I went back and forth between the two before going with the Panny. I have 99 hours on the AE700 and use component for standard 480 dvd and 1080i or 720p hdmi for hd dish tv. I have had no white flashes of any kind, period. According to others, your mileage may vary as there seems to be some very real variations among units that may also be a result of different sources and applications.

I'm very happy with this projector(my first) and would recommend it to anyone. Watching a great movie or hdtv on a 123" screen is pretty hard to top. Either the sony or the panny will do just fine, but I liked the longer throw distance and versatility of the Panny. Contrast differences between the two I suspect are of lesser weight in the real world than the rooms and screens used in conjunction with each projector. Pick your poison and enjoy.

Pinco_Pallino
12-12-04, 12:50 PM
After many thoughts I am also considering going for the Panny. I already bought a component 8m cable (sigh!) and have a cheap multi-region Sony Player. If I went with the Sony HS51 I would have to upgrade my DVD player (and get some hack for the regions) and buy a new cable to connect DVI. More than 50 posters on the PJC site are happy with their purchase and I will have to do the adjustments to avoid VB IF there is any on the one I receive).

Also I really like the extended throw: I will simply put the ae700 on the bookshelf and that's it.

The Sony may have a better contrast but in the end I believe the differences are acceptable (at least to untrained eye as mine). Also there are really issues with delivery and I would like to have my apparatus as soon as possible: can't wait bringing in the kids of the neigh-borough for a movie seance during winter time so that they do something together...

It won't be my last projector either...

12-12-04, 03:41 PM
With regard to max cable length... is it the signal type or the cable that determines the max length. For example for HTPC we are running a DVI out signal through HDMI cable (2 different ends on cable)... so are we limited by the DVI spec for max length if this is a DVI signal? OR do we now gain a greater max cable length from the HDMI spec?? (ie. are we limited in some way that the video card can only pump out so much through DVI?). I want to know how long I can go on cable length here using a DVI to HDMI cable and not sacrifice any quality.

Also, anyone here try half life 2 on the AE700? That has got to be amazing.

Thanks.

I've noticed that also. I don't understand why HDMI is not as sharp or better than a VGA connection with a 1:1 pixel mapping. Right now, I'm sticking to VGA just because of this "effect". In short, on my projector, HDMI is not as clean as the VGA connection.

Is this normal?

Thanks.

"HDMI is not as sharp or better than a VGA connection"
This all depends on a number of your settings I believe. With a 100 people calibrating with avia or video essentials you would get 100 different settings, or less;) You would get a lot of different settings, anyway.

BTW - "Sharpness" is a bad word for most videophiles, I think.

lpr
12-12-04, 06:09 PM
Well, by sharpness I mean that the edges of fonts on a 1280x720p desktop are not clean... they are noisy and not well definied, one could say that it looks like edge enhancement... all this with sharpness at 0 or -4 on HDMI. With a 1:1 pixel VGA connection, there is zero noise around the edges.

Take care.

Mister694
12-12-04, 06:55 PM
ok... i have a possible explanation... As you may know Windows has Edge Enhancement built into the OS. However, it goes by the name ClearType (http://www.microsoft.com/typography/ClearTypeInfo.mspx). You can change the settings of this feature to your liking by following one of the links on the page i linked to.

Now the good news, I do not currently have my hdmi cable with me so someone else will have to try adjusting the cleartype setting in windows.... By its nature of being a pure digital feed, the HDMI should show more detail than the analog signal of VGA. I am thinking that this may be the reason for the text to look like it has EE over HDMI but not while using VGA..


Sorry if this does not help, but i hope this helps most of you

benjust
12-12-04, 08:27 PM
close but no cigar..

i am using cleartype, but i made note of the double up-arrow which is completely unaffected by cleartype (see attachment).

somethings definately happening to hdmi input - and as was suggested, changing the 'sharpness' level had zero effect.

llamameat
12-13-04, 04:44 AM
it's an adapter. It won't degrade or change the picture in any way since DVI is a subset of HDMI and it's a digital signal (so you either get it or you don't).

work the the Panasonic A97S player and the switcher. It seems like a
timing issue. I agree that a firmware update would probably solve the
problem. We should all complain to Panasonic about this and the

I noticed on a british forum site that the Z3's were recalled for a firmware update to fix an HDMI bug that they said momentarily "mashed" the screen. Not sure if this is the same thing as the white flashes, but it seems that the problems with the new projectors are due more to not-quite-there HDMI technology than problems with the projectors themselves. If Sanyo has come out with a firmware upgrade that can fix the problem, perhaps Panansonic isn't far behind.

Aren't we all overlooking something very obvious ?? - HDMI is digital, so there is no reason why it couldn't be used for firmware updates. Assuming there is a setup menu option of somesort that puts the projector in update mode you then put a CD-R in your DVD player, hit play and a few minutes later, instant update :)

There are plenty of dvd players on the market that update firmware this way. You download the update from their website, burn the iso to cdr and put it in the player and hit play.

Something new -- this white flash talking is getting old. Yes, I have them.

I mounted my AE700 to the celing this weekend. (See rant below) Anyway, now the bottom of the image is curved up in the center by a 3/4 inch. It's 12 feet from an 85" wide screen. I have the projector pretty well aligned to the screen -- dimensions and diagonals are within 1/4" of each other. Lens is 8" below top of screen.

Why the curve? Wasn't there when table mounted.

Also the projector is higher front to back. Setting it level gives me huge amount of keystone. Is that normal?

Rant:

Ask me about trying to run in cables in a wall where some previous owner must have removed a huge patio door from when they enclosed the patio to make the room that I turned into my theater.

Can you say 2x12 header?

Hours of drilling later, I took a break and asked my wife, "how about we just re-arrange the room and put the equipment on this other wall"!! Her answer: "Okay, I'd like it better on the other wall, anyway."

Did I say hours of drilling and I still hadn't broken through and NOW she says we ought to rearrange it anyway? To where I only have to drill through two 2x4's that are the top plate? Not through 2 2x4's plus 2 2x12's the long way, plus apparently another 2x4!!!! From a cramped area of the attic?!!

the cable is a 2m piece by lindy.. it's the shortest one i could get, direct dvi to hdmi, no adapter - the htpc sits about 30cm away from the projector :)

remember that this is a digital link, interference would cause eratic image data dropouts throughout the picture, not such an effect on high contrast areas.

while that's certainly possible, i can't see why any device would do such a thing.. but i wouldn't put it past manufacturers to fudge up a perfectly good image. i wish there was a "good = on" setting that just mapped image data to the projectors panels, without messing the image up - but i guess that's too much to ask :)

edit: okay i can see why someone might do this - if theyd bought 1,000,000 analog in/out image processors they wanted to get rid of :P

With LCD's the panel is in fact being controlled by analog voltage control so there is one final D/A conversion.

remember that this is a digital link, interference would cause eratic image data dropouts throughout the picture, not such an effect on high contrast areas.

Sorry, not thinking clearly - I was reading HDMI and thinking VGA.:rolleyes:

Do you think that ALL the AE700 have the white flash issue ? I've been comtacting the Portuguese Panasonic in order to obtain confirmation about the problem and the future solution.

They did not answer me, but put the question to others. As soon as I obtain any answer I will report about it.

12-14-04, 12:23 PM
No it is definitely not on all 700s. I have never seen the problem. I have over 250 hours on mine. Mine is a japanese model. I think that is why. Nobody I know has a japanese model and has flashes.

The native resolution 1280x720p. 1080i looks nice but 1080p looks best. I would keep it at it's native res to reduce conversions. Less conversions = less artifacts. Try them all out and see which one looks best to you.

I have a standard European AE700, bought it 1.5 weeks ago. Haven't seen any white flashes... I think - it could be that I don't know what to look for. But a white flash sounds like something you really can't miss. Haven't noticed any VB either, but then again, I'm not looking for it.

HDMI from HTPC. VGA from Dish Network Model 6000. Component from switcher which has Pioneer Elite dv-47, xbox, and ps2. Svideo from Laserdisc player. RCA Video from VCR. I switch sources rarely enough it not a huge problem. My 700 basically does all of the switching except for component sources.

To add to the white flash issue I received a call from our local Panasonic support person that I have been working on this issue with.
He called and told me today that the Panasonic engineers are aware of the problem and feel it is an HDMI software version compatibility problem.
He said they are working on a fix and perhaps it will be a firmware update.

Fingers crossed on this one! :)

And how will the firmware be updated? Is using the hdmi port an option ? I for one am extremely reluctant to ship my projector anywhere knowing the abuse a projector can sustain in transit. It is conceivable that my projector will come back far far worse than when it left.

rwestley
12-14-04, 05:01 PM
I got the same answer regarding the white flash and the cropping issue.

I did ask how they update the firmware but the person I spoke to did not have any idea. Keep calling them requesting a fix. The more who call the
more they will realize they have a problem and fix it. When you call be
sure to mention both problems and any others you might have so they
can get a good firmware fix.

Focus problem.

I have a hard time getting the whole picture in focus. I use lenshift at almost max downwards. if i focus at the bottom, the top will get out of focus. And visa versa. If i focus at the middle the rest of the picture will be out of focus.

And the the picture ain't straight at the bottom either, it is curved.

wiredman
12-14-04, 09:01 PM
exsodius,
I've noticed the focus problem as well. I to am using the lenshift at almost max downwards. Would it help to turn it upside down? The fan seems to get a little louder but would the pic be better with the lenshift in the "dead-middle"?
I can't try until this weekend.

12-15-04, 03:42 AM
So, I have a dead pixel which appeared at 150 hours :(

It's not in the center of the screen, it's about 1/3 from the bottom and can be seen easily during any dark scenes.

My question is should I bother going through the hassle getting this unit replaced via the warrenty or am I fighting a losing battle? My fear is that I'll get a new unit and it's only a matter of time before a new deal-pixel appears and maybe I'd be better off just getting used to this slight flaw.

Would I at least get a fresh bulb?

Just bought the AE700 and am up to 25 hours lamp time. The image and everything has been great....up until 1 hour ago. I was watching Lord of the Rings when then screen suddenly overlapped or crossed and went white!?? Well it seemed like it.

The right third of the screen was ok but the middle third was overlapped with the left third....well this is what it looked liked! I got very sacred and turned the projector off....waited and turned it on againd and it was perfect, no problems.

Is this the flash that everyone is talking about? What could it be?

Any help I will be greatly appreciated so I can prevent it from happening again

It sounds far more severe than the "white flashes," but it does sound like another type of sync problem.

What is your source, and how is it connected? Would HDMI be a good guess?

How does the NEC LT240K compare with the AE700? They have fairly similar specs, aside from the DLP/LCD difference, lumens, and aspect ratio (I currently have a 120" 4:3 which I intend to keep because it fills my wall nicely).

Is the AE700 markedly better in overall picture quality?

I found that my picture quality improved by 1) being sure that the projector is perfectly level(used a level to help eliminate the tilt) and 2) by minimizing the lens shift, which in my application wasn't a big deal as I have the projector on top of a component cabinet.

With ceiling mounting(when shelf mounting is not practical) I'd try to get the projector as low as possible, no tilt and as little lens shift as possible.

What is a level? Is it what we in norway call "water"? With a air blob inside to see that things get straight? :D

Hi there,

I am getting really scared. I was going for the panny, but every time I look at your comments it appears as if something new is happening. I know not everybody suffers from all diseases, but what if I had bad chance?

So far, it seems that we have:

- Vertical banding
- White flashes
- Cropping
- Reduces sharpness with vertical shift (This worries me since I was planning to shelf mount it and project the image top down.)
- low black levels

and what else?

Alright people, update on these issues. I've made the call too, and the service rep that I spoke to said that prior to yesterday they hadn't really heard of the 'white flash' problem but since yesterday, they have had a couple of people call about it, so YES, DO CALL IN AND LET THEM KNOW. Otherwise they'll just consider it a small isolated problem and maybe won't do anything about it.

Even if you experience it but think you can 'live with' it, please call it in so at least they'll do something about it and help everybody out.

***Important note: When you call about the white flashes, also make sure to mention that there is the cropping/masking problem at 720p and 1080i. The tech I spoke to asked his product manager about it and said they "had never heard of this problem", so make sure to tell them about that too.

The more people report in about it, the greater the chance that they'll actually do something about it.

Pinco_Pallino,

Most of the worrying about the issues you mentioned is an attempt to induce mass hysteria, whipped up by people who feel better if they get everyone else hysterical along with themselves.

I have over 200 hours on my Panny and it's a great box, especially for the reasonable price. You'll worry yourself sick if you take too much notice of the complaints listed here in the past couple of weeks. The only ones left contributing seriously in this forum are the die-hards who like to grind axes... any axes. They're never satisfied. They use demagogic phrases like, "Come on people...[phone/ring/write/hassle an allegedly unresponsive Panasonic]" because they imagine they're leading some kind of crusade. Several have posted triumphantly that they've returned their units. One said he was "happy" about doing this twice.

For $2K you're not going to get heaven-on-a-stick 35mm, 6500 Kelvin cinema quality out of a 1280 pixel machine using LCDs to project a 720 pixels-wide image in your rumpus room.

Any VB there is usually goes away after the unit warms up. Flyscreen-door effect won't bother you if flicker is set correctly (many posts here on where and how to do this). Cropping is minimal: a few pixels (most of the diehards only want it fixed because... well... they just want it fixed, that's all... they like being unhappy). White Flashes? I realise now I've never seen 'em. I did experience that sync problem once (mentioned on the previous page). Never had it again. It was probably a defective DVD data stream that temporarily confused the WSS-detect logic. Changed my (ancient) Toshiba DVD player to a newer Sony (about time!) and it's disappeared. Even on the Toshiba it only happened once. Need for expensive cables? I made my own (Y-Cr-Cb) with some co-ax audio cable, RCA plugs and a soldering iron. Beautiful pictures. Cost $NextToNothing. Black levels? Very good. I use a pink-colored filter to enhance them, but even without the filter they're still pretty good.

The AE700 is not a lemon.

There may be some defective units out there. They should be fixed. But most of this thread is now being fed by just a couple of guys trying to start some kind of "Projection People Against Panasonic" movement. Wouldn't surprise me if they worked for the opposition.

There'll be something better along in the future, but in the meantime...

Don't take everything you read here too seriously (including me).

I gotta agree with aussie bob! for the money, all of us Pani 700 Users are quite fortunate! indeed we are enjoying pq that only rock stars and major athletes used to enjoy... sure it cannot be perfect and I have to admit when I saw my first VB I panic'd! but having this forum along with so many generous knowledgeable people helped me get over it! another thing; this is PANASONIC we are talking about not a mom and pop's operation! I'm sure they are paying attention to what is being discussed in this forum and others and perhaps we'll all find solutions to this minor glitches; but over all I am fully satistied with my 700U... and can't wait to see what they'll improve in the 900U....just imagine the possibilities....

Abdul Jalib
12-15-04, 08:05 PM
Yes, the bottom line is that you get a great picture for a great price, and these are relatively minor flaws. The only thing that seems like a real "gotcha" is if you must use HDMI on a copy-protected source (and you can't use a HTPC or Bravo D2) AND the white flashes bother you. Perhaps that "gotcha" will get us all once we move to HD-DVD. The cropping is livable. The vertical banding is mostly eliminatable. Mostly.

One thing I'm a bit confused about, though... In some other threads, I remember people saying stuff like "DVI looks a zillion times better than VGA!!!" But in this thread, the consensus seems to be that a quality VGA cable is darn close to DVI/HDMI. Does it depend on the projector?

But if I read the above correctly you are not using the the HDMI port with a DVD player that supports HDCP (HTPC's don't count as they don't either). If we read the thread we will discover that the vast majority of the flashes are occurring with this config so it makes no sense to say you are not experiencing flashes unless you are using the HDMI port with an HDCP player.

I could just as easily say I'm not experiencing them either but then again I'm not using the HDMI port with HDCP.

Bob I'm neither hysterical nor demagogic (and in using such extreme language I might suggest you are pontificating). I agree that the AE 700 is a fine machine especially when the dollar is factored in but to say there are not issues in particular with the HDMI port is to be misleading, If I recall you do not utilize that port and thus would not experience the problems that quite a few have reported and then to turn around and suggest that those who *do* have these issues are rabble rousing is at best insulting.

Issues with HDMI have been reported on the Z3, HS51 and the AE700 which suggests that there are definitely teething problems going on, The Z3 and the 700 issues sound similar and many have pointed the finger at HDCP issues. This should be fixable and for those of us who would like to see this addressed by Panasonic as it is being addressed by Sanyo, and to suggest this is counter-productive is very unfair.

Are you driving HDMI with 720p or 1080i and have you tried 480 to see how the internal scaler on the Panasonic compares with the D2?

Only con (not huge) is no upscaling on Component - or am i mistaken?

BTW once again if you call in about cropping, don't just say "hey there's cropping." Don't forget this is not some mysterious flaw - its right there in the manual in the appendix. The AE700 doesn't currently allow WIDE720 mode using HDMI - this is the 720p mode without cropping - instead it uses 750p mode which has cropping. The AE500 supported WIDE720 using DVI without cropping and so should the AE700 with HDMI. We lost many modes for the digital input in the AE700. Just point them to the 2 manuals and say "hey we lost WIDE720 mode support for HDMI".

Liowink, Good point....I did mention the manual and the fact that the AE500 did not have the problem. I think they know what the problem is and they are working on it. Only if enough people call in will they fix it.

Keep Calling and be very specific.

I wonder if you got a car that had some problems on it would you not try to
get them fixed. Most of us love our 700's but we would like to have the
few problems resolved. I don't think it is wrong to try to get Panasonic to
get things right. It will only help them sell more projectors and will build
up good will with its customers.

What is your source, and how is it connected? Would HDMI be a good guess?

By Source you mean the DVD player? it is a pioneer DVD and I have it connected by an progressive(I think) Component input. It has only happened once....been working fine since!

I have know problem with VB....and I have notice 1 white flash which is hardly noticable but this problem...'out of sync' you think was serious!

I will try the Wide Screen select which was mentioned on the last page.

How about using a D1 over DVI through a Gefen DVI switcher? Works flawlessly.

AussieBob Storm Post: Very well put.

And to give another perspective, look how wildly successful these Panasonic units have been (AE500 / AE700). They are consistently among the most popular models sold wherever I check. The online retailers freakin' LOVE us and our 170 page threads. Who loves us even more? Panasonic! Marketing companies die for this chatter - good more than bad press but exposure is exposure. Look at the Paris Hilton diaries....
If the 500/700 were a "lemon" as some would claim then it would've died a while ago! Nobody (including Panny) is in the business of trying to lose money.
Bottom line is WE the consumers are the winners! The almighty greenback determines what happens to a product line. Who is going to be able to spend more in R&D, product evolution, upgrading, etc.? A company that sells 1000 units or a company that sells 10-50x that? I'm not disputing the fact that there may be some issues we'd all like to alleviate (or in some instances a truly bad individual unit - VB is my only compalint with both my 500 and 700) but rest assured of one thing: unlike some competitors whose product lifecycles are going to be painfully short, we can rest assured that Panasonic is going to continue to fund display technolgies and we'll continue to have better technology at a completely fair price point for years to come. I love my 700 and wouldn't trade it for anything of equal value....right now!!
Have at!

PS: I've recently been archiving some old super 8mm film to DVD and have the old projector sitting in my theater from the 70s. Man is that loud and the image is quite dim. Couldn't help but think how far projection technology has come in 30 years. What next? Holographic images from our wristwatches?

Just got my 700 today and have been messing around with it all night. I'm very impressed with how HD material looks...about how I expected it to after viewing it on my rptv. I'm a little disappointed with how DVDs look, but I guess that's the limitations of the format. Right now I have a Sony ns725p hooked up via components and am projecting onto my wall. I also hooked up my PC via VGA, played a few DVDs, and couldn't see any difference in PQ. I'll be ordering a HCCV screen tomorrow. Hopefully it'll give it that extra "punch" I'm looking for...DVDs seem a little washed-out on the wall.

Other than that, no real problems. Can't see any VB and very little SDE. Overall, I'm very happy with the purchase. :)

EDIT: Also, would it be possible to get some impressions from people who have been using the new Sony 975 player? I did a search and didn't come up with much except for someone who reported seeing a few white flashes.

Just go buy a Qualia 04 and stop worrying about it. Seriously. :-)

I've owned a number of projectors. Examine this next set of words carefully:

You. Will. Not. Find. A. Better. Projector. For. The. Price. Period.

I have NEVER seen the "white flashes" on any input and I feed this thing everything but RGB analog.

Vertical banding is so slight as to be a non issue.

Croping. Yeah. 8 scanlines. OMG!!!!!!!! Seriously, not a big deal. Considering I get 1:1 pixel mapping form my NVIDIA equipped HTPC I don't care. Try doing that with a PLV70 and powerstrip.

Vertical shift reducing sharpness? No. Every pixel is indivdually resolved, smoothvision reduces screendoor to a non issue. This is not even an issue. I just checked.

Anyway, buy it from a reputable retailer (online or not) and if you get a dud then RETURN IT. It is that simple. Pony up the extra cash and buy an HS51 or go for the equivalently priced PLV Z3. There are other options but I garantee you that when people buy as many of those as have purchyased the 700U you will see a simillar litany of issues. Unless you are willing to spend seriously more cash you will not find a "perfect" projector.

I just replaced the DaLite High Contrast Da Mat (.8 gain gray) in my setup with High Contrast Cinema Vision and this thing really pops now. I love it.

Again. You. Will. Not. Find. A. Better. Projector. For. The. Price. Period.

Well I have had my 700 now for a week and have clocked 24 hours worth of use. I have it teamed up with a Momitsu V880DX player and the picture quality is awesome. I have noticed the same things that everyone else has, that being VB if you leave it in standby and the bottom of the picture being slightly deformed if you use too much lens shift etc, but all these things can be overcome. Certainly nothing to get bent out of shape over and all the people I have had over to watch a movie are literally gob smacked by it.

They all say why would anyone buy a plasma or LCD tv when you can get this kind of PQ at this size screen. I have to admit I feel sorry for those people who have paid big bucks for those TV's cause they are not a patch on the picture that this PJ puts out.

If you are sitting on the fence with this purchase then all I can say is get the fence out from between your legs and dive on in the water is great.

Well I've clocked over 150 hrs on my 700 so far and can say without hesitation that the unit is just great!!! Viewing both HD (OTA) and DVD's.

HD is just something else! Avsolutely no complaints at all. It's just stunning.

With DVD's it's all about how the DVD was mastered. I just watched Philadelphia (Tom Hanks and Densel Washington) and this mastering was done in 16:9 and is flawless. I could barely tell the difference from HD.

On other DVD's the quality is questionable so it's not the projector, it's the DVD!

If you're on the fence about this projector, order one, dim the room down and be prepared to be blown away!!

I'm also about 150+ hours on my AE700 and couldn't be happier. I think a lot of the white flash sync issues comes from the fact HDMI is in it's infancy, and really this is the first generation of displays that utilizes it. There's going to be some hiccups.

I've got an ATI 8500DV hooked up to a newly purchased Panasonic AE700 via a DVI/HDMI cable (30' Bluejeans cables). I have been experiencing intermittent ghosting/syncing issues with these two devices (I have the Panny hooked up to a Directv HD box without any problems). The usual course of events is a few minutes into a DVD or the Win XP desktop, the image will suddenly go screwy. Things seem to go out of phase and the reds are suddenly blown out, looking like a snowstorm with the remainder of the image looking very grainy and awful. It will persist for approximately 1 minute and then reset itself looking all fine and dandy.

I know that the cable is fine since I have hooked it up to several DVI output devices (Directv STB and a spare DVD-DVI player) and the only place I get this is with the HTPC. Does this sound like a hardware compatibility issue between the ATI card and the projector? Drivers? I have tried various versions of ATI's drivers and likewise used third party drivers like Omega.

Thoughts?

I'm making this same post in the HTPC thread, if that's ok...

Thanks. So you can actually tell the difference between component and an upconverted signal over HDMI?

Also, has anyone else tried Xbox with this projector? HD looks great, DVDs look pretty good, but my Xbox looks like crap on this projector. There is TONS of VB, the colors are murky, and I can't get it to display it in widescreen. I've tried the flicker contols for VB, but I don't see any flickering on any of the screens.

Ted, I am using the D2's "DVI" output at 720p and do occasionaly use it in 1080I; the reason why I say occasionaly, is that in my own personal point of view; 1080i looks better when watching "film"...meaning no "special effects or Computer animation" is being projected, for those types of movies I use 720p; the difference I find is that 1080i for such movies can be too noisy in contrast to "film" where it looks life like. Regarding the scaling... the D2's scaler is better than the pani's but then the Pani's is better than the faroudja found in the Denon....that was the benefit of testing all these different units out!

I assume you are using the xbox hi-def cable (component out, not just s-video). I have one of the older ones that has rca jacks on a box, rather than male rca cables coming out. Anyway, I get a great picture. You do have to go into the setup of the xbox menu to enable widescreen, etc, and the game has to support it. There's a site called HDTVArcade.com that has a list of which games support widescreen and/or hdtv. Few support full 720p. I played THUG2 with my wife on split screen (96-inch wide DALITE), and it's awesome. It supports 720p. It's like each person gets a 50-inch bigscreen TV to themselves. I've noticed no problems with vb or bad colors. I played HALO2 briefly, but for some reason it didn't stretch out to 16:9. There may be some game setting also that I missed. I rented that, so I haven't messed with it much. Even so the picture was stunning. I put it in JUST mode to have it fill the screen.

I am about to receive my AE700 and would like to buy the most compatible DVD player. I've read all the replies in this thread, but still am not clear whether any of the upconverting DVD players significantly improve the picture with either HDMI or Components inputs. There seem to be contradictory responses, even with the same player.

The most promising DVD players from what I can read here seem to be the Sony 975, Bravo D2, and Momitsu 880. However, it appears that, using HDMI, none of these players appear to do away with the white flashes completely, and none are able to use the WIDE720 mode with HDMI to eliminate the cropping/scaling problem. Am I right about this?

I'm very interested in answers to the questions below from owners of upconverting models who are already using them with the AE700.

1, Which model of upconverting DVD player do you own?

2. Picture Quality: Do you see a noticeable difference in overall picture quality when you upconvert WITH HDMI?

3. Picture Quality: Do you see a noticeable difference in overall picture quality when you upconvert WITH COMPONENT INPUTS ( if your player can do this)?

4. Cropping: How much of the screen is cropped or improperly scaled when you upconvert WITH HDMI? Can you compensate with aspect adjustments in the player?

5. Cropping: How much of the screen is cropped or improperly scaled WITH COMPONENT INPUTS (if your model can do this)? Can you compensate with aspect adjustments in the player? Can you display the WIDE720 mode using the component outputs?

6. Progressive: If you have the option, do you find that the picture with progressive scan is better, worse, or the same as with non-progressive scan?

7. Flashes: How frequent/annoying are the white flashes when you upconvert?

8. Overall, if you have tried two different DVD players with your AE700, do there seem to be any significant advantages to your upconverting player over the other player?

I realize that: (a) none of these players are a substitute for a Panasonic firmware upgrade; (b) picture quality also depends on other factors, like lighting, screen, etc.; and (c) all answers are subjective.

But, despite these limitations, I think it would be very useful for AE700 owners if you would take a few minutes and answer whichever of these questions you have experience with. It might clear up a lot of contradictory posts.

How has brightness/ color uniformity been for people now that the AE700's have been in the field for over two months now?

Go into the Service menu and project a white field (or a white field from a DVD/HD/PC source).

Are there any brightness/discoloration issues, particularly corenrs and near the image perimeter all the way around?

Yes, I am using component out. I actually have two. One that is just a regular component cable and another that is a little box that allows you to plug in component cables along with optical. Now that I switched to the box, the color is definitely better, but I'm still getting horrible VB. It looks like dirty bars a couple inches thick all along the picture. Eh, too bad. Since flicker controls seem to be fine, is there any other way I could tweak this out?

Here's a picture of Timesplitters (I assume the pictures I take will look better once I get a screen):

What I can say is that the Panasonic S97 over HDMI is excellent. I use the 720p setting.
Nothing trumps HD, component or HDMI. With a SA 8300HD, there's no alternative now but component. So the S97 gets the HDMI by default.

Jeff,
I have the Panny S97S hooked up via HDMI to my AE700 and I love the picture. I have tried both 720p and 1080i upconversion and they both look fantastic. Admittedly, I can't tell much difference between the 720p and 1080i. As far as the white flashes go, yes I get them about 2-3 times per movie. It doesn't bother me because they are so quick. In fact, while watching with other family members, nobody else has said anything when it happens. Of course, I know/knew about it from this forum but decided not to say anything just to see if anyone would comment on them. Also, there has been some discussion about the macroblocking issue with the S97 and while I have noticed it a couple of times it is extremely rare. I would definitely buy this player all over again.

Holycow - Try to use some lower #s in the flicker setting, even if it induces a little flicker. Also your xbox as a source is showing off it's poor scaler. Turn off 480p and let the projector do the scaling. It is a better scaler anyways.

Alright people, update on these issues.

Otherwise they'll just consider it a small isolated problem and maybe won't do anything about it.

Even if you experience it but think you can 'live with' it, please call it in so at least they'll do something about it and help everybody out.

***Important note: When you call about the white flashes, also make sure to mention that there is the cropping/masking problem at 720p and 1080i. The tech I spoke to asked his product manager about it and said they "had never heard of this problem", so make sure to tell them about that too.

The more people report in about it, the greater the chance that they'll actually do something about it.

I called today and YES it is very important that more people call. (More voices make things move faster) The rep that I spoke with on the phone said that he has been receiving a lot of calls over the last week about these two issues. He also said that they will be working on a solution to these problems - and I should hear back from him within a week. He took my name, number, and email too. For anyone deciding to purchase this projector, it is HIGHLY recommended. I only have this one problem with split second white flashes that occur a few times duing a movie... and please note: This only happens over the HDMI cable and not component cables.

I have this same problem. Mostly noticeable on B&W films. Noticeable w/ all my DVD players and various signal sources. This is the last bug-a-boo on my 700 I would like to correct. Maybe I'm using too much lens shift. I'll have to do some testing. If not correctable - I guess I can live with it.

Thankfully VB is now a thing of the past! That is something I don't think I could have lived with had it not been correctable.

Extreme lens shift is know to cause the color uniformity abnomolies you mentioned. You can read up more on it in this thread somewhere between page 87 and 145. lol

Seriously though, minimum lens shift, projector level more or less in the center of the screen will give you the best picture.

At least VB is a thing of the past! That I couldn't live with - if it were not correctable.

Luckily for me its not major - though I still wish manufacturers would provide a way of turn off the colour matrix for those of us who enjoy B&W in all its colours. ;)

As far as correctable - the problem reminds me of shading issues that can occur with broadcast cameras - and it is fixable.

I would think we would need access to all the controls that are available to utilize the service screens that are available in the OPTIONS + menu. I would love to have access to the tweaks that those screens are for - I *do* wish someone had access to a service manual.

Yes - I know. I just really like my 700 up high hugging the ceiling. I could lower it 3 or 4 inches if I had too. Just don't know if this is enough to correct the color uniformity. Like I said I'll have to do some testing.

Rockytopps or anyone else - Can you quickly verify that upscaled output from S97 or other upscaling players is noticably better than 480p/i DVD player upscaled by AE700, with same component or HDMI connection. Has anyone done a side-by-side?

The key question is should ppl spend the $ buying an upscaling DVD player vs 480p DVD output.

just called panasonic.. about the flash issues etc... and they took my name, e-mail and phone # and said they would get back probably in a week.. got the same response as everyone else... " have only had this problem reported a couple of times.. but we are aware of the issue.. etc".. those using hdmi should definatly call... Tim

Big debate for me is whether to use the HDMI port for my HTPC or the DVD player. (No I don't want a switcher)

I can understand ted.... so just wait for the new wave of processors that will have DVI/HDMI built in switching... on the other hand if you already have an HTPC why use a DVD player? as I understand you have more advantages with HTPC than DVD.....

Rockytopps or anyone else - Can you quickly verify that upscaled output from S97 or other upscaling players is noticably better than 480p/i DVD player upscaled by AE700, with same component or HDMI connection. Has anyone done a side-by-side?

The key question is should ppl spend the $ buying an upscaling DVD player vs 480p DVD output.

Thanks very much to anyone who is kind enough to respond. Roy

I can honestly say that thru my personal experience the correct answer is: Go to your neighborhood major electronics store; buy whatever upscaling dvd player you can get your hands on; bring it home.... connect it to the panni and spend some time watching, then switch to another player.... if it is possible for you buy a range of units from the cheapest to the moderately expensive ones... you will deffinately see a difference and your eyes will not deceive you!.... if you can try to get your hands on a Bravo D2, because it does not use HDCP I think the white flashes are not an issue with it.... and the scaler is the best I've seen and belive me I've seen quite a few!!! so in short a good scaling DVD is the "present" sure bet until....HDDVD or Blue Ray....

Sorry to inform you but lowering your PJ 3 - 4 inches won't help with this. When I first got the PJ, I initially mounted it it literally dead center onscreen. Zero lens shift but zoomed in to the max (largest image for distance). I noticed the color uniformity problem as it made the left side of my screen a little cyan and the right side of my screen looked a little magenta. I then played with the zoom and checked it at neutral position, maximum and minimum and came to realize that the color uniformity problem is an issue with the lcd panel position and the refractive properties of the Panny's lens cluster.

At max or mear max zoom, the left edge of the screen has a cyan cast and the right edge a magenta cast, however, at minimum zoom, the left half of the screen now has the magenta cast and the right edge has a small cyan fringe. The phenomenon is similar to chromatic aberration in some camera lenses but not exactly the same. In photo lenses, the chromatic aberration is due to different wavelengths of light being refracted to slightly different degrees and becoming visible because they are spatially separated in the image. The Panny's problem though is that the slight difference in position of the LCD panels causes the light from each one to be refracted to a slightly different degree at the edges of the lens cluster. That's why at the minimum and maximum positions of zoom, I saw the color cast switch sides.

I immediately assumed of course that finding a way to fill the screen with the zoom at neutral position would eliminate any color cast but unfortunately that turned out to not be true. As I slowly changed the zoom from maximum position to minimum, there was no single position at which color cast was eliminated. Close to the center/neutral position in my PJ, the color cast would start showing up on both sides before the switch. I ended up leaving it at approximately 1.8 zoom of a possible 2.0 maximum. For me though, this is not a serious problem. Even in the few B/W that I've viewed, I don't find it overly annoying. My #1 problem is still the white flashes, followed by the VB. With about 160 hours on the PJ, I again forgot to turn the power off at the mains and the overnight standby VB popped up again. Had to leave the PJ off for 2 days for it to reduce back to former levels.

On the plus side though, with more people calling Panasonic about it, perhaps in a week or two, they will have a fix for it.:D

As usual its the friendliness issue.

My daughter (who is 9) and wife have used the HTPC for playback in the past but for movies they really just want to turn on and go.

Not to be Rude or anything but if the issue is your wife and daughter... I would be willing to bet the shirt off my back that they don't care as much about PQ as you "the videophile man" would.... so then why not use the component input from a reasonable progressive scan dvd player and leave the HDMI port for your personal enjoyment???? VOILA!!!

Ah, but I would rather just touch and go too.
Besides the wife is an artist - she knows her stuff and the daughter - well she hears and sees better than I do anyway. ;)

Long term I'm sure it will go that way but not for now. I'd rather use a dedicated box and for the time being that unit is being used for other duties. Besides I'm not convinced that the difference is that great.

To those of you who called Panasonic, did anyone find out how the firmware will be upgraded (assuming that it's simply a firmware fix)? Will it require taking/sending the projector to a service center, or can we upgrade the firmware ourselves somehow?

My panny 700 has exactly the same uniformity characteristics as you've mentioned. No way to eliminate it even with center zoom and no lens shift. Wonder if such an issue is inherent to all LCD projectors? Had posted here earlier asking for advice if I should return to dealer for exchange, even posting sample pics for all to see my level of uniformity. Not many has responded about same problem until now. Glad that I did not returned it earlier as it seems to me now that all the AE700 seem to have this color uniformity level but is being overshadowed by other issues, like Flashes & VB (which I personally don't find them any bit an issue compared to this color uniformity thing).

Most color scenes do not reveal the color uniformity issue. But once you pop-in certain movies that are B/W or mostly mono-toned (like Final Fantasy-the Spirits Within), you may start to be bothered by it.

Having said the above, I have to remind everyone that I am still very happy with this projector in all other aspects of image quality, given the price paid. Just that if this color uniformity is not a common problem across most LCD projectors in this price range now, then I think Panasonic should not be forgiven for having it in theirs.

I've been given some advice by a seemingly dependable source as to the DIY method of removing dust blobs in the 700, along with some pitfalls specific to the 700 to avoid as I proceed.. A while back I posted about the early (under 40 hours) onset of the problem, then contacted Panasonic, who told me to contact the outfit that handles their PJ repair/loaner program. I did, and they told me that in the (likely) event that Panasonic or my retailer would not cover this under warranty, I'd be looking at about 3 hours labor at $135.00/hr. This wasn't exactly a soothing balm for what ailed me. Upon reflection, I think this included some diagnostic measures, and I suppose a straightforward cleaning might be less. Anyway, my kind advisor feels that the self-sufficiency of developing such a skill would eventually come in handy for any (microdisplay) PJ owner who will take care not to be too klutzy around the exposed innards. Also, according to him, the lack of a clean room is not as much of a problem as one might think.

I'll give it a whirl (carefully) and report back with specifics for the other 700 owners who have complained of the same malady.

On a different, more current note, I was dismayed at the cool/warm color uniformity problems which sound identical to the ones related by other members. Black and white images are quite disappointing because of it. Another PJ guru has told me that filters exist which will block all color and rectify the problem. This sounds too easy. Can anyone corroborate this? I wonder how much overall light would also be blocked. I'm going to a Lee Filters dealer tomorrow morning to begin the process of Cine4home/AussieBob style filter tweaks for brightness & contrast enhancement, and I'll run it by them & report back.

Joe Schwartz,

According to the Panny service tech I spoke to, if a firmware upgrade is developed that will eliminate the white flash and/or other probs, we will most likely need to send our PJs in to get them updated. I did ask if they might be able to do the updating via a CD loaded through an HDMI connected DVD player but the service tech said he hadn't heard of that being done with their PJs before. BTW, off topic but did you get lots of corny jokes when 'Spaceballs' first came out?

AVGadgetBoy,

Yes, unfortunately the color uniformity is a design issue. I do believe the Panny might have it to a little higher degree than the Sony projectors for example. Not sure how the Sanyo's do in this regard. As I've said, the problem is exacerbated by the Panny's zoom lens cluster. The better the lens cluster, the less problems of this sort occur. I don't recall seeing any color uniformity issues of this degree when I was checking out the Sony HS20. They may have been there, but I think I would have noticed if they had been present to the degree I see in my Panny because I was scrutinizing the HS20's picture in detail for any and all flaws I could find. Went with the Panny sight unseen because of the higher contrast rating. Personally though, I don't watch a lot of B/W material and the few that I have watched haven't bugged me as much as my pet peeve, the white flashes. For the most part though, I do think it is a good PJ for the pricepoint. If they could fix the few probs with it, that would make it all the better.

(If that's the case) - not having a DIY firmware update is really pathetic in this day and age. My $25 router and CD burners have flash updates. This projector is almost 100 times as much money and they didn't think to put a flash update for the firmware. I mean this thing is more expensive than most computers! That would just really be a *complete* lack of foresight. I really hope that's not true. I wonder then - for people buying new ones are they going to put a new version number so we know how to tell the difference?
(how am I going to recommend this to others with white flashes) Does anyone know how to see the firmware version number on their current model?

Thanks! for the info! You saved me a lot of time testing this weekend.
I wonder if a filter would help w/ The color uniformity issue??? Pop it on just for B&W films. By the way - my Panny 500 didn't have this issue.

I have a Denon DVD-1910 (upconverting player) and the 700, and after 200 hrs and tweaking, I actually prefer the image produced using component outputs @ 480i from the Denon vs. upconverting!!

Does this make any sense??? (At least one other person on this forum has found the same.)

All this talk about "near-HD quality" using upconverting players with the 700 makes me think I'm doing something wrong, but what?? (I have a 16' Blue Jeans DVI > HDMI cable and have tried various DVDs at 720p and 1080i.)
