On my 96" screen I sit 9ft away which is slightly closer than THX recommendation. I chose 96" because that's the point where I can clearly see the difference between 760p and 1080p.
Just check out acebydavidsusilo.webs.com for the full specs of my HT.

THX is old fogies. Don't let anyone tell you where you should sit. I sit 7' from my 120" screen. I started with blackout cloth taped to the wall to try different sizes. bo cloth is almost free at fabric stores. I tried 2.35 too. I ended up liking 120" 16x9. I also like the iMax effect so 7' it is for me. I did 6' but my feet would hit the center channel speaker when I layed back smile.gif I have a 13' wide wall with the screen on it. I painted the whole room flat black. Didn't care if it is pretty with the lights on. Even with flat black walls I see reflections off the side. It would be best to put some black cloth sound deadner panels there.

Brightness at full zoom is not an issue. 24p looks film-like to me. 2D Blu-ray is great. I have no complaints on that. I just wish the 3D for this projector is better.
This projector allows for adjustment of the parallax (via the 3D View Monitor), but it is NOT saved and gets reset anytime the input is changed of the power is turn off/on. Here's what the manual has to say about it:
7557901718_9dcab91bb3_o.png
I also wish I had waited a little bit for the non-lamp version that has been announced, but there is not enough info out there on that new projector to make any kind of conclusion on it.
Honestly, it's possible that active 3D just doesn't make me as happy as polarized 3D. It's virtually impossible to eliminate crosstalk with active 3D.

The PT-AE4000U's 3D picture quality is completely broken unless you use some very specific settings. If you want absolute flexibility in terms of 3D picture settings, don't buy a Panasonic.

If you can live with the settings that work:

1.) Lamp set to ECO
2.) Picture Mode set to NORMAL

Then you'll have an almost crosstalk-free picture. If you change any of those settings, it's bloody awful. And yes, this is proven already.

More proof?


Here's the end of Transformers 3 Blu-ray in 3D, with picture settings other than the ones I listed above:

6cd1a347.jpg

And here's set to the settings listed above. Note how there is no perceptible crosstalk:

31b6aebd.jpg


And please do NOT ask how to bring that menu up, because I simply won't be revealing that information.

Want to test this for yourself? Load up a 3D movie, pause it, and then turn on "High Altitude Mode." Sit and watch your paused image for up 60 seconds, and literally see the crosstalk get worse and worse. We think LCD panel temperatures are NOT being regulated correctly in this projector, and our guess is that Panasonic simply didn't test all the different picture modes to make sure they all worked.

Hey, how do I get to that menu? wink.gif

Not sure the "don't ask" statement was necessary but thanks anyways.

It was necessary because I've gotten a ton of messages about such things in the past (flooded inboxes are just a nuisance!), because people inevitably notice. I was asked not to disclose how to get to that menu, and even with the fact that I'm getting NO further help from Panasonic despite my hundreds of hours of troubleshooting 3D crosstalk with the PT-AE7000U, I will respect the wishes of the higher-ups within the company.

That said, I'm frustrated that Panasonic has basically said, "We don't care," when it comes to crosstalk. Unless you use very specific settings, you're just out of luck.
post #3816 of 4428
Meh...

How can you respect the "higher ups" of the company when they clearly do not respect you enough to address your crosstalk issues...

Who cares about the darn menu. Why post a pic with it in the first place anyway? And I agree, the comment was unnecessary. Not making a lot of friends here.
post #3818 of 4428
Let me clarify: Two wrongs don't make a right. While the Panasonic higher-ups may not respect us enough to fix the issue, I'm not going to compromise my own integrity.

Second, the reason those photos even have that menu overlay are because I took them several months ago to try and help Panasonic fix the issue and I didn't want to take new photos. Excuse me for trying to help you all.

Ahhh, working for them… Make sense.

I didn’t mean to come off as having a tone with my response. No offense intended.

Do you actually own the 7000 or just worked on it for a short period of time?
post #3820 of 4428
Not a problem. I should have explained those photos were older, and not just taken yesterday with the overlay to stir up trouble.

Yes, I do own the 7000. It's mostly an excellent projector, but I can understand people's frustrations with 3D crosstalk if they change any settings. Heck, even changing the lamp from ECO to NORMAL increases the amount of crosstalk. It's really bananas. Earlier in the thread I suggested Epson's reasoning for locking out basically every single picture setting when you watch 3D material on their 5010 model is to address the very issue the PT-AE7000U suffers from. That said, if you leave the lamp to ECO and the picture to NORMAL and don't touch any other settings, the 3D picture is pretty fantastic on the Panasonic.

I've repeated the issue with 3 different projectors. Two of my own (Panasonic replaced my first one because of the issue, but my replacement behaves just the same), and a fellow forum member here I was working with reproduced the exact issue with his PT-AE7000U.

I'm guessing Panasonic don't want to draw too much attention to the problem because, at least in part, there's no way (simple way, that is) for them to issue firmware updates without capturing the system itself (a pretty awful design choice in 2011/2012).

Does that menu contain also some other adjustable settings that help with minimizing crosstalk, in modes other than those you've listed earlier as optimal, or it contains mostly measurements as shown on pictures? Does it contain anything to minimize fan noise?
(Notice I'm not asking how to activate it. smile.gif)

I can't really say more about the menu, but I will say that there are no adjustments that can be made that would affect crosstalk (sadly). Otherwise I'd have a fix for everyone. smile.gif

I commend you for your stance! Integrity is something that is rare and lacking nowadays. Kudos.

PS: Is it odd that I find crosstalk to be less when I use Normal light (not Eco) and High Altitude Mode OFF (not ON)? Or am I deluding myself?

William (great name by the way, it's my surname too), thanks for the suggested fix. I'll try it tonight and get back to the forum.

No you're likely not deluding yourself. First, High Altitude Mode should definitely be left off. That, for me, was the single worst setting to even change (not that you would?). If you pause a 3D movie, turn on High Altitude Mode, and watch the screen for 60 seconds, you can literally watch the crosstalk get ghastly, unwatchable.

Hopefully some adjustments help you out. Be sure to leave the projector to run for 15-20 minutes after changing settings to let the lamp/panels normalize.

Not a problem. I'll try to be clearer in future. Reading back over my post it did come across slightly bizarrely. Anyway, glad that's all cleared up.
post #3827 of 4428
Sorry for the misunderstanding William. I'm glad I don't know about the secret menu anyway, more menus = more opportunity to mess things up. lol. Could you elaborate on how to easily switch aspect ratio's while watching a 3D movie as stated earlier in this thread? I'm completely lost.

Hi William,
I still monitor this thread in case anything useful pops up. I think you may have been a little quick to make a blanket statement like the above (no negative tone here intended).

I really feel it's a combination of settings that make the crosstalk go away. For me, Normal picture mode is simply too dim on a 2.4:1 137" screen at 1.3 gain with projector mounted 18ft back. I must use Dynamic mode and don't feel the colors suffer much as the skin tones are still excellent. Dynamic does not add any more ghosting than using Normal (for me). I do use Lamp on Eco. What is certainly "proven" is that the dimmer the picture is, the less ghosting. This is just the nature of the LCD glasses. So maybe my Dynamic lumens on screen is same as your Normal lumens, I don't know. I'm just saying that I don't think the magic bullet is the Picture setting. I found other settings that really matter for me, besides the well-known warm-up issue. But please don't ask me what those settings are tongue.gif

I noticed a hint more crosstalk in Dynamic Picture mode than normal (it bothered me enough to not use Dynamic mode). And yes, while generally the brighter the image is the less crosstalk there generally is, with the Panasonic this isn't always the case. For example, Cinema 2 Picture Mode is a considerably dimmer image than Normal (it puts out way fewer lumens), yet shows a good deal more crosstalk. Heck, turning on High Altitude Mode does NOTHING to the image brightness/settings, yet crosstalk becomes completely unbearable.

My friend (engineer) and myself still believe there's temperature to blame here. With High Altitude mode on (all this does is crank the fan up to keep the lamp cooler at high altitude locations), the LCD panels are probably cooling off too much as a result of the fan speed, causing the panels to be slower, - hence the crosstalk. Again, this is just a theory, not a fact. But why else would turning a fan up cause such ghastly crosstalk, right?

With regards to the other settings causing crosstalk, there has to be something going on that the Panasonic isn't managing, thermally, to keep from getting "out of spec" in regards to mitigating crosstalk. Why that is I don't know, and Panasonic have become extremely tight-lipped about the whole thing.

As it stands, I justifiably believe the PT-AE7000U to be a "defective" product. I should be able to bring my projector home, turn the lamp to NORMAL and run my image in Cinema 2 (which I believe is the "Hollywood-calibrated" setting) and expect a crosstalk-free image. But I can't.

And believe you me I could use that extra brightness. I'm running a Seymour Screen Excellence 1.0 gain AT screen. Thankfully it's "only" 100" diagonal, with a 12-foot throw. I can't imagine how dim that would be in 3D at a greater distance/larger screen size...

Erm I'll have to check when I get some movie time. smile.gif I'm sure someone else can answer this question, though, in the meantime?

First it was Sony cutting back 60% this year on consumer electronics. Now its Panasonic:

I certainly agree there should be an LCD temp control of some sort. If ghosting is so susceptible to minor temp changes, Panasonic should have thought of this. It really should not be, but something in the design is causing such a sensitivity.

Lately I've had virtually 0 crosstalk and I wonder if it's because my theatre is that much warmer in the summer. Even though the A/C is running, I'm sure the projector is running hotter these days. I also haven't noticed as many people complaining as they did during the Winter. Maybe it's a placebo effect. tongue.gif
post #3834 of 4428
I noticed that as well. I haven't had any crosstalk since Mayish....

I though it was just me. But my room is about 5-10 degrees hotter in the summer.

I thought I mentioned something about room temps back when everyone was having ghosting problems in the winter months? Again, it may not just be the projector, the glasses are liquid crystal also and are susceptible to the ambient temperature

Hi everyone,

I am interested to get the Panasonic PT AE7000 but I would like to check first if this projector is compatible with our current lounge set-up.

Can I can use the vertical lens shift together with the "lens memory" function (to convert 16:9 to scope screen) at the same time?

I would like to mount this projector at the back of our lounge room but we have a small chandelier in the middle of the room, it is mounted directly from the ceiling and is about 16 inches in height (from ceiling to edge of chandelier). I am getting a scope screen but I am not keen on spending $$ for the anamorphic lens. Hence, I am getting this projector (has both lens shift and lens memory).

Thank you.

Well, assuming at some of us know how to recall the "menu" - could you tell us at what temperatures (exhaust and filter) does YOUR device obtain a ghostless image?

There's roughly 7 degrees celsius difference between your two "Transformers" shots with and without ghosting.

Good catch! Looks like Summer is the season to enjoy 3D movies.
post #3839 of 4428
I don't buy it. My projector has horrible ghosting and the room is really warm.

I'm also wondering if I send it in, if they will update the firmware and fix the convergence issue. Perhaps a newer firmware would "improve" the ghosting?

Let's get specific then - what are the readouts on your unit when you get ghosting?

Besides ambient room temperature theres lamp mode, picture mode, mount (ceiliing or standing), air density (which the "high altitude" setting was made to battle), air filter density (dust collection etc).

Do you get ghosting when the sensor named "filter" is 100 degrees celsius?
