As posted previously, P50 usually is a reference to Fujitsu.

Threads like this cause people like me to go looking for trouble! I'd been watching a lot of MSNBC on my 3 month old Panny 50PHD6UY during the days leading up to the election. Until recently I used to alternate between 'just' and 'zoom' when watching MSNBC in order to move that damned logo around. But doing that got old and I guess I got complacent. I had not noticed any burn-in/retention/ghosting/whateveryouwanttocallit from my normal viewing distance of about 13 feet, but tonight I decided to take a closer look ( ). Well, it's VERY faint but parts of the MSNBC logo (mostly the letters) are there- more noticeable with white screen than black. To be honest, I really don't care very much since I can only see it if I get within 3-4 feet of the screen, and the previous posts offer encouragement that it will disappear over time, but I will be severely limiting my watching of stations with non-transparent logos from now on! But it would be nice to check in a week or 2 and find that it's gone.

What is displayed at 1400x1080?

And you're right, there's little 1080p content now, but HD-DVD and Blu Ray are probably about two years away, and I for one tend to keep my sets at least 5 years. So if I can be ahead of the curve now, more the better

Generally the highest rez material we see today is the video from HD cameras. I beleive those generally will go out to about 1400 lines of horizontal resolution. As far as HD DVD and Blu Ray, it was my impression that even those will not be in the 1920 rez category and probably more akin to D-Theater.....but I could be wrong.

Here's probably a more important point to consider when thinking about the full 1920X1080 displays coming down the road. Aside from the absence of any software material at that resolution, if at this point most people can't see the difference between a 42" ED vs HD display at 8' or more (an even bigger difference than the HD plasma displays of today vs. what's coming), I believe we'll see the same issue of people simply not seeing the difference at typical viewing distances. Of course once we get to screen sizes of approximately 80" or more, I would believe that extra resolution WILL be obvious....assuming we have 1920X1080 high resolution material to display! Thus far we haven't even been close.

All the testing that we have done with DVD Forum on HD-DVD have been at 1080p so the encoding will certainly be at 1920 lines. However, this does not say that the telecine transfer had that resolution. Clearly for computer generated content such as Shrek, one can expect the full resolution out of BD (blu-ray) or HD-DVD formats. And over time, telecine equipment will no doubt improve to produce closer to the full resolution of the formats.

Here is another consideration. With HD content encoded in 1080, staying in that resolution all the way to the display will mean better images even if the content doesn't have as much resolution. By avoiding a downsample in the display to lower resolution, one avoids the artifacts introduced in that step.

Rob, Sorry I got you looking. I was really surprised when I turned on the white screen and saw the weather channel logo. My wife agreed to keep off this channel for a while and I will post back if it goes away.

I do agree with you that this may only be a "white screen" issue. I don't see it during any programing,but I will be keeping a look out.

what I don't understand is how this image ghosted with not all that much viewing vs other content. I would never have expected to see the logo ghost with an hour a day of on/off viewing.
post #307 of 2990
FWIW,

We have the 5uy Panny, we (me and the kids) play x-box (Halo) quite a bit. Average about 15 hours per week on a total of ~ 44 hours per week.

We also watch HD and SD ("just"). The display has been professionally ISF'ed and my "brightness" setting is set to -20 all other to 0.

We have no burn-in...I have experienced "image retention" and it did fade away. I will check the hours on it tonight to try and get some sort of bearing.
post #308 of 2990
I just checked the hours:

WT 2786
PT 2676

Received this set April 2003, equates to roughly 141 hours per month, or 4.62 hours per day.

YMMV.
post #309 of 2990
math08, robandalex, what are your picture settings? I'm curious if you happen to have higher brightness/contrast, or if it's set low?

Picture (contrast) -7
Brightness -1
Color -2
post #311 of 2990
Wow, what a thread, just read it all. I have a few questions though:

1. Turn the contrast and brightness down low, how low? halfway? have it at 1/3?

2. It's been mentioned to allow the phosphors settled in evenly(?) the first 100-200 hours. So would it be a good idea to have the white screen on during the day (8 hrs) while we're at work.

Thanks for a super informative thread.
post #312 of 2990
Wow, roger that robnalex. I knew that you'd posted to other threads about keeping your contrast down, so I knew it was low, but I wasn't sure if it was "lower" and not "low", if that makes any sense.

Your settings are lower than mine, and I've had my set sit on CNN for hours at a time with an issue. I wonder if it's simply a case by case, unit by unit thing.

vdmai, I turned most of my settings down mostly due to the DVE calibration disc and Rich Harkness's Steaming Rat settings thread. It just so happens the "lower" settings provide a more realistic image than the torch settings most units ship with. I think my picture and contrast came at 25, they're now both at 0.

post #313 of 2990
Juice- I don't recall what display you have (mine is Panny 50PHD6UY) but I would assume that if I left CNN on for "hours at a time" I would get the same result. As I mentioned previously the image is VERY faint. I really have to get within 2-3 feet from the display and really look for it. I would never be able to see it beyond 5 feet, and since I sit 13 feet away I'm not really concerned. But I don't watch MSNBC anymore!
post #314 of 2990
Does anyone know if the bars that appear on the sides with SDTV broadcasts in the DVI more cause plasma burn. Also while watching DVDs do the bars that appear on the top and bottom cause burns?
post #315 of 2990
i have a pioneer 4340, ive played maybe 2 hours of ps2 over 2 weeks, never more than 30 minutes at a time. the screen is calibrated yet there seems to be burn in. Ive been running the tv all day trying to see if maybe it is temporary. it seems that a lot of it has gone away. Is this normal? how do you know if tis burn in?
post #316 of 2990
It's only burn-in if it is permanent... sounds like it is disappearing, so it is probably just image retention.

2hrs of PS2 over 2 weeks should not do this unless the brightness is up way to high. Most plasma's come out of the box with the brightness cranked beyond what is needed. Check that and you should not have any problems.

post #317 of 2990
Greg,

Go out and buy a dvd called either Avia or DVE (Digital Video Essentials) they will help to get your set looking very good and out of "torch mode". As a bonus you may even like the PQ better.

Good Luck.

how long would it tke for imgae retention to disappear

This is a Dishnetwork-International digital channel. Its expected to be on 30% of the total TV time. Can this Channel's logo cause a burn-in on a latest EDTV plasma in JUST mode?

Note: Most of the time there are no black bars in programming, I just picked it to easily see the logo.

Thanks for any input.

My guess would be that because of the stark contrast between the white letters and black background that that logo would eventually burn in to some degree.
post #321 of 2990
Hi--noob to the thread...anyway, on my plasma the things that I have seen to cause the most "damage" are the gray bars that my cable box uses for SD/4:3 content....it seems as if the line between the picture and the bounding bar burns in pretty bad...but this "line" is not visible when the actual bars are on the screen, only on an idle black screen...so far this has only had a ghosting effect, but it seems to make some pretty deep marks...my dumb cable box doesnt allow me to control the stretching of an image...on an SD channel, the only options are "zoom" and "normal" and on HD channels it has "zoom" "stretch" "normal"...any one else notice this?
post #322 of 2990
I used DVE last night, and it helped a great deal. Learned a lot of stuff, too. Didn't care for the way the menu is set up (kind of confusing...) Things are much better with new settings... Looks more real and natural, yet still offers a decent "pop" of color to wow over (even moreso in Nemo and other animated films...)

The screensaver never came on and Shrek 2's motionless "Far Far Way Idol" selection screen was on the screen for a while, not the image is retained. Hope it goes away. Not sure why the screensave didn't come on...
post #323 of 2990
How effective are the bright grey bars on the Consumer Panny at preventing uneven burnin?

The consumer Panny doesn't have a wobbler feature will the bright grey bars cause a line to develop where the 4:3 picture ends on the sides and the grey bars begin?

If I watch a 4:3 program (45 min.) but with black bars instead of grey, then afterwards send a black image to the screen and have that black image play for the same time but with the grey bars on would that have the same effect of watching the 4:3 program with the grey bars.

Is there any chance of uneven burnin with a transparent logo like NBC or CBS?

Thanks all.
post #324 of 2990
How often should I use the screensaver and for how long?
Just got the new TH-42PHD7UY. I have HD Directv tivo and DVD connected via component. Normal use. How often should I use the screensaver? Which one? How long should I use it for each time? Any advise appreciated.

Thanks.
post #325 of 2990
I've had my 50" Panny since August 2001. I did a calibration using the Avia disc when I installed it. I've been reasonably careful, although during 9/1I I watched a lot of CNN. We watch TCM letter-boxed films, but NO game playing. I use justify for SD, but we mainly watch HD cable. I do avoid those channels with dark logos (like CNN). I had the set ISF'd recently and the technician confirmed there is no sign of any burn-in.

So I'm contemplating a 60"-70" display for my family room. It will be our main display for movies, TV, and games.

The big question is whether or not Plasma is ok for video games yet? I'm talking 3-5 hrs. straight once a week or so and even more on birthdays etc.

The upcoming Sony Qualia RPTV (1080P) and Samsung xHD3 (1080P) are my two main candidates, but I keep reading plasma is much improved and I see plasmas in airports with continuous computer display.

So anyone know? Have any links to papers, etc.?

Thanks,
Ken

I play hours of xbox on our 42" pwd6uy and I've never had an issue. When Halo2 came out, this turned into marathon nights and weekends of xbox gaming, 3-5 hours as you mentioned Ken. Playing games on a plasma isn't an issue, just keep it on JUST and make sure it's been calibrated properly (turn down those torch factory settings).

Every game has save screens, cut scenes, chapter breaks, etc. that swap out static HUDS that might worry you.

post #328 of 2990
Juice, has the petition (with the 1025 signatures) regarding logos been sent to each and everyone of the TV channels? I've noticed an improvement, but there are still too many channels whose logo is opaque, obtrusive and damaging. I -- and I am sure many other plasma owners -- stay away from these channels.
post #329 of 2990
Update on the weather channel ghost. Still there after 4 weeks. I only see the very light ghost on the white screen, however, watching a Christmas special with white snow, saw the ghost in the snow ( i was looking for the ghost to see if it showed up on a white background).

Over the past 4 weeks, have used the white screen a number of times, and made sure that whenever my wife went to the weather channel she had the set on normal, which placed the logo in a different spot.

Any other suggestions to try to get rid of this?

Thanks, Mike

Does your set include a "picture inversion" feature? If so, go to the Weather channel, turn on inversion, and let it simmer.
