post #1051 of 1081
OT: All Blu-Rays are supposed to output 1080i(@30). Some output 1080p@60; some output 1080p@24* or 1080p24sf*.

As far as I know, all HDTV's accept 1080i.

You will have to shop for a Blu-Ray player that outputs 720p. Even though you really should get a review or do viewing tests, chances are that getting 720p out of the player will yield better results than feeding the projector 1080i and letting the projector convert (to 720p).

Well, that's not necessarily true about needing a 720p Blu-Ray player. While in theory I do agree with you, the execution of each Blu-Ray unit isn't always the same, thus 720p may or may not look best. My old up converting Zenith DVD player that I use to have looked considerably better feeding the Z4 1080i than it did 720p. It all depends on the device and how well it renders any particular resolution. I've compared my Time Warner SA8300HD cable box at both 720p and 1080i and while it depends on the content of the show I think 1080i tends to look a bit more colorful to me.

At any rate, from what I can tell, most Blu-Rays can output more than just 1080p so read some reviews, download some user manuals (don't rely on website specs or in store sales people to tell you) in order to see for sure what the units are capable of and get the best one for the money. To me, Playstation3 still is one of the best deals out there for Blu-Ray.

The manual says it doesn't.
I want to get a Bluray player and I think only a few output 720p or 1080i.

Right now I can only recall the Pioneers BDP-50FD & 51FD

Everyone experiences with bluray players are welcome
Thanks.

I own a Z4, and I use a Samsung BD-UP5000 for playing Blu-ray, HD-DVD and standard DVDs. I have the Samsung set to 1080p, so I can verify 100% that the Z4 WILL accept a 1080p signal. I used to have a 40GB PS3, and I used to set it to 1080p as well.

To my eyes, setting the Samsung to 1080p instead of 720p, or 1080i, provides an image that is slightly sharper. It seems to me that the scalar in the Z4 is responsible for this difference, slight as it may be.

When inputting a 1080p signal, the information screen shows "DVI" at 60hz.

As a matter of fact, the Z4 will even accept a 1080p/24 signal. In this case, the information screen shows "DVI" at 24hz. Unfortunately, however, the image shows frequent tearing, and doesn't smooth out panning shots. It seems to me that although the info screen shows 24hz, the Z4 is using some kind of pulldown and converts the image to 60hz internally.

I highly recommend trying High-def media at 1080p/60 on the Z4...just forget about 1080p/24.
post #1054 of 1081
now this is an interesting subject once again for Z4! Just when I thought the subject was pretty much dead.

First question is how do you get your Z4 to show 'DVI' when it only has an HDMI input? The best you can do is take a DVI device (like my HTPC is) and get an adaptor box to send HDMI to the Z4 (like I do). Mine only will say D-720p or D-1080i. Do you guys have a older firmware that's displaying differently? Or a different model that has a DVI input? I've never seen it say DVI for anything.

So time for the experiment. I still have a 1080p player in a box waiting for me to setup my new receiver with HDMI switching so that's out for testing until I get it going. So I do have my HTPC which can output 1080p. From everything I've read the PC outputs 1080p, not not 1080i, so I think it's a legit 1080p test. I don't know how I can tell on the HTPC to see if it's sending i or p...just going to assume p. So, I set it to do 1080/60...and the Z4 accepts it, yet displays D-1080i. Not sure what to make of that... It would appear that somehow the Z4 is displaying my HTPC's 1080 signal, yet it shows 1080i @ 60 not DVI @ 60 as you are seeing. So I don't really know if it's the Z4 that's converting 1080p to 1080i and I just have a different firmware than you guys (newer??) or if the HTPC is really just sending 1080i (which I don't think is the case). Any thoughts?

This week when I setup my Oppo 1080p DVD player I'll report back when happens when it's set to 1080p.

If all else fails contact Sanyo and let us know the reply!

Well, that lamp caused me more aggravation, so I put the original back in. Did a lot of googling and many of the reviews for the Z4 were showing up with revised reviews saying, "Great projector but the free lamp from Sanyo sucks." Several people with apparently the same problem, and whenever they contacted Sanyo they would get a nice reply of "the lamps only have a 30 day warranty, and you have had it for over a year. Sorry, nothing we can do."
Luckily I got one of those extended lamp warranties from my projector dealer at cost. I called them up and told them my lamp was doing these weird things. (Ok, so maybe I didn't mention it wasn't the original lamp they had warrantied. Sue me.) And they shipped out a replacement in under a week. I supposedly have one more replacement if anything happens to this one within the original ext warranty period.

It shows DVI when the 1080p signal is input.

I switched the oppo to 1080p. Yes, it displays a picture. No, I dont think it is any different than the 720P setting on the oppo.

When I had my system calibrated by an isf tech he recommended that the settings into the sanyo be the same resolution as what the sanyo outputs to avoid any scaling errors.

This is a different case though. Your Oppo is scaling a 480i/p signal up to 1080p and then the Z4 is scaling it back to 720p. As you said, it's better to set the Oppo to 720p instead of 1080p in that case. Otherwise, it's being scaled above and then down to the Z4's native resolution, which really isn't necessary. It's not really a problem either way, since you won't see much, if any, difference.

However, I was referring to sending a 1080p source from a Blu-ray player out at 1080p, which the Sanyo scales down to 720p, as opposed to having the Blu-ray player scale the 1080p image down to 720p and then outputting that to the Z4. I've done it with a PS3 and my current Samsung BD-UP5000, and I've found that the Sanyo Z4 does a better job of scaling down to 720p than either of the two players I mentioned. Not a HUGE difference, but a difference nevertheless. Since the original source in this case is 1080p to begin with, it needs to be scaled down to 720p, but I think the Z4 does an excellent job of scaling, so I let it handle the scaling.

Best thing is to try it and decide for yourself which you prefer. You can't hurt anything.
post #1058 of 1081
Other possible options to an addition of a blu ray player for the sanyo are the new apple device which allows 720 video and 5.1 audio on demand for the price of a rental with no monthly fee or contract. The cost of the apple is less than half of a new panansonic blu ray.

Various U.S. satellite providers are now touting 1080p video on demand.

It seems as though the blu ray market segment might be short lived.

Is anyone using the Panasonic bd-35/55 blu ray player with the z4?

Does anyone have a problem with the bd 35-55 not keeping the selected output resolution when the unit is powered on when connected via hdmi to the display?

I have tried a couple of units now and they all do the same thing. I set it for the native resolution of the display,
the next time the system is powered up the output resolution is changed back to auto in the player menu and the resolution is incorrect on the display.

Anyone know a way to lock this feature in the player?

I am trying to determine if this is a handshake issue with the projector or a problem with the player itself, if there is any question why I am posting a blu ray quesiton in the z4 thread.

I have one more while at it. When the projector is powered up if I am listening to a cd via hdmi the sound will mute and not return unless the reciever is turned off/on agian to reslect the cd source. the dealer is pointing the finger at the z4.

Has anyone experienced this problem with multiple hdmi sources and the z4 projector?
post #1060 of 1081
re: BD35 -

maybe a firmware update? latest is 1.6. just give it a LAN connection and it will check/update automatically.

i use a v1.6 BD35 through an HDMI switching receiver and experience no such issues (never ran earlier firmware, as soon as i powered it up out of the box it updated 1.1 to 1.6).

i have output locked at 720p, as i think the player does a better job of scaling than the receiver. receiver accepts any res, so should 'look' as flexible as the projector in that regard.

not quite the same as your setup i realize, but just another data point...

My Z4 has 2300 hours on the lamp and I have a brand new one waiting. I've had many projectors over the years and this one have been up the longest. Are there anymore happy Z4 members out there?
post #1062 of 1081
After a power outage caused my Z4 to stop working at around 1300 hours, I discovered that opening it up and resetting the thermal switch got it back to working. It's now well over 2000 hours and looking very good....if a little dimmer. Can't say that I haven't been thinking about one of those new 1080P models though.

On my 3rd lamp! 1st 2 both made it over 2500 hours. Still happy but the upgrade bug gets worse as time goes by. I use it for TV, sports, movies, games - everything.
post #1064 of 1081
I'm extremely happy with my Z4 and SANYO's warranty. Last summer my HDMI input stopped working after our house took a lightning strike. Shipped it overnight on a Friday on SANYO's dime, they fixed it Monday and I had it back Tuesday! Great service!
post #1065 of 1081
Still happy with mine, but the urge to go 1080p is getting the better of me.
post #1066 of 1081
The upgrade bug always bits me ,but when I look at the Z4..welll.....lets just say...I brush the bug off. if I go with one it will be a sanyo.
post #1067 of 1081
I've got Analog / VGA from an HTPC and I've tried ROne's writeup and find myself wondering if I've made things better or worse.

Within this thread, I've searched for references for somebody tuning Analog / VGA and I've not seen anything...

Does anybody know if the same principles apply to Analog / VGA too? Is there a writeup for that?

I've got an nVIDIA 9600 card, if that makes any difference.

Thanks in advance.

I used your settings and in my opinion there is still way to much red. Now I'm not sure if it's my Z4, but it's leaking red in the lower half of the screen. Turning red way down fixed it for me, and the picture looks superb!
post #1069 of 1081
I am glad you are enjoying the settings and the Z4!
When you say leaking red, that does not sound good though. But if you tweaked it out great.

Yea I'm not sure what it is. There is just way more red on the lower half of the screen than any other color. Could there be something wrong with the red lcd panel? If so, anyway to properly take care of the problem?

I have not used my z4 for approx 1year while building my theater.

recently calibrated using rones settings and also with dve
set brightness and contrast according to dve

picture looks ok but very dark overall even with manual iris at 20 and above

pushing gamma to +4 makes image much more watchable.

I don't remember havong to set gamma that high previously. remember trying
+1 or sometimes +2

using oppo 83 dvd- diy light gray screen (n9) projecting from 12 feet away
on 96" screen. Screen color and size unchanged from previous use.

I only have about 600 hrs on original bulb but do have a lot of on/off usage

could my bulb be that dim/goin bad?? have others increased gamma setting to compensate for dim bulb?


tried calibration using hdmi L1 and L2 doesn't seem to make a diff.

appreciate any thoughts

So I just picked up an old PLV-Z4 from Craigslist for $75 for outdoor viewing. Lamp had over 3k hours on it, so I replaced it for $150 and with the help of this thread got it looking really good. I'm quite impressed by this little gem. Anyone out there still using theirs?

$75 (projector) + $150 (new lamp) + $25 (black out cloth and some PVC) = Very nice, super cheap outdoor theater

Even hooked it up in the basement with good results. Makes me wonder why I'm currently looking to spend $5k on a projector for the basement.

I just passed five years in May, and I still use My Z4. I've been tempted to upgrade to a 1080p projector, but the Z4 picture still looks fantastic!
post #1076 of 1081
I sold my last projector Hitachi TX-100 3 years ago. and got a nice 46" flatscreen.
But, I have realized that 46" does not give that WOW experience, even if you got Full HD. So, I've just picked up a Z4 for 300$ and bought an original Philips bulp for 260$ and bingo the home cinema is up and running again.
post #1077 of 1081
Wow, surprised to see this thread revived!

I still use mine (semi) regularly - 10 hours a week at the most. I have had it 5 trouble-free years, and I am still impressed by the picture. I have been targeting a 1080P projector for 3 years but have not been able to pull the trigger. My Z4 likely has quite a bit of life with the current bulb, so I don't know when I will take a serious look at an upgrade.

And I have upgrade-idis as much as anyone.....

I am still loving my Z4 after 6 years. I do believe a newer 1080 projector would have better resolution and a richer picture overall, yet by how much? I'm always impressed with the color accuracy of this thing and it has never caused me any problems.
post #1080 of 1081
Beginning my 8 year with the Z4... smile.gif

Still going strong. This is my main TV, so over the years, I used it on an average 4 hours/day.
These are the lamps history hours:

1 lamp (original) : 3,103 hours (Still work, yes!)
2 lamp : 2,878 hours (dead)
3 lamp : 2,069 hours (still strong)

At 2,500 hours, I will by a other lamp, just in case.
Since TV programming is still at 720p. I will wait 2 or 3 years to go on a 1080p projector.

LOVE MY Z4 biggrin.gif
