Which plasmas have mechanisms to guarantee the prevention of screen burn

The only thing putting me off plasma is burn. I know someone who recently got it bad within a few months of ownership (DVD-recorder OSD and SKY channel bar permanently visible on a white screen), so don't tell me it's a thing of the past.

I like playing games and would like to hook up my PC but I know these are high risk activities with a plasma.

I know all about running plasma at low settings for the first 200h but at the end of the day burn is irreversible and the manufacturers won't be bothered if I get it.

It wouldn't be difficult for the plasma to "know" if it will get burn, by the amount of time its pixels have been static, and then apply measures to prevent burn (eg change colour of pixel, or move whole screen around very slowly, or move the whole screen around slowly regardless).

I'm sure these mechanisms exist so which screens have them?

PS. do any plasmas allow you to watch 4:3/2.35:1 with horizontal/vertical letterboxes, whilst preventing uneven image degradation (eg by making the black bars the average brightness of the rest of the image).

Make sure you understand the distinction between Image Retention and Screen Burn. :)

THE SAMSUNGS HAVE TWO TYPES OF SIGNAL PATTERN AND ADJUSTABLE PIXEL SHIFT. Oops, sorry i just noticed i left caps on- doh !! This helps get rid of retention. Burn is a different matter i believe. just be careful and don`t go daft with contrast and playing the same game for two or three hours and you should be ok.

There isn't a distinction, it's the same thing :mad:

'Image retention' just sounds mode delicate. If manufacturers plastered 'screen burn' in their operating instructions, etc. no one would buy ! :eek:

They are two quite different things.

If the set suffers image retention then it can usually be easily rectified by watching moving content or in the worst case using a white screen for a short time.

Screen burn is an irretreivable level of damage to the phosphors on the display.

On a correctly setup plasma screen burn is a thing of the past and with most models even slight image retention is difficult to acheive.

"Make sure you understand the distinction between Image Retention and Screen Burn."

Image retention is reversible but screen burn is permanent. Seeing as my pal has had burn 6 months I would say it's the latter (and he's been taking care to avoid further damage since I first told him).


"THE SAMSUNGS HAVE TWO TYPES OF SIGNAL PATTERN AND ADJUSTABLE PIXEL SHIFT"

That's what I like to hear, any others?

BTW If an anti-burn guarantee doesn't exist just let me know which sets have anti-burn mechs - I'm sure I've heard that some commercial panels have them too.

There is a massive difference between image retention and screen burn (as already stated by ceenhad - thanks :smashin: ).

We use our Plasma (Panasonic PWD6) every day for approx. 7 hours a day; I use it for 360 gaming too. I have never once experienced retention or burn however I have seen it on two other screens (both Pioneer); IMO both down to careless owners not running their displays in correctly and generally having wrong settings.

My LG has a white screen mode (whitewash), contrast reversal, orbital (moves picture a couple of mm in different directions at random every x number of minutes etc As far as I'm aware all plasmas have these features but nobody can or will offer a guarantee against screen burn. Some makes are more succeptible to it than others but you could burn ANY plasma on the market if you tried too. I have a 50" which I use for everything from 360 gaming to HD DVD and I have only ever seen a small amount of retention which goes after a couple of minutes of whitewash.

This run in DVD is utter hokum.

You should just use a normal setup and pay particular attention to getting the contrast and brightness set correctly.

Some of the "run in" settings here are almost unwatchable!

Change it out of dynamic mode

My Pioneer 507XD has the functionality to completely stop screen burn / image retention.

Pay attention to the little button located at the front bottom (oh-errr) left hand side of the screen surround. When it is constantly blue, then you must be careful with regards to image issues.

When it is orange, then it is running in complete image retention / burn safety mode.

I agree. I have worked in retail, and manufacturers have told me that people are wasting their time with the 'run in' settings.

I asked recently and Fujitsu have told people to set their white screen to run over night for the first few weeks to let the screen work to it's optimum.

You will always get retention. This is due to the plasma gasses having a slight charge. If you put BBC News 24 for example for an hour, turn to a black screen and you may just still see the aston. It's the same as a florescent light, switch it off, and you may notice it will still glow a little. I know Fujitsu use a white screen, which if you run for 1 minute, all retention will be gone. They also use ALIS in some of their older plasmas, which also helps to prevent screen burn. There is also a screen orbiter setting that wil move the image around the screen so nothing is in the same place.

Screen burn is not really an issue for the home. Commercial plasmas it can be visible because they usually have static text and images that are one for days or weeks at a time, and they are usually NEC panels which have a low quality glass.

screen breakin is very important not only does it help image retention but it also improves the overall PQ of your panel by properly breaking it in and by properly using a calibration disc

Well, at least I thought it was funny.

The Panasonic commercial screens will move the image round 1 pixel at a time so the static images like logos are not always in the same place, but that is irrelivent to be honest as they don't suffer from burn anyway.

As long as you set it up straight out the box you will be fine with these sets.

I have left the Singstar menu on for 12 hours and not had a problem, left teh Zelda menu on for 10 hours and leave kids channels on for hours at a time, no problem at all.

You don't need running in settings at all, you just need to set it up properly at the start.

It's absolutely ridiculous that you have to worry about image retention/screen burn at this price point. Once screen burn occurs - and it does occur - your plasma is basically f****d.

To me this is unacceptable and with the likes of Sony's W2000 displaying better PQ and Blacks than Panny's plasmas i think plasmas are a risk not worth taking.

These two terms are being grouped together yet again. No-one needs worry about image retention because it's temporary and is still quite rare on properly setup screens. Screen burn is serious but properly setup plasmas will not suffer burn unless the owner is either daft or does it deliberately.

As for a Sony displaying better black levels than a PH9... well, let's just say I'd be very surprised if that was the case. By all means stay with LCD but you're not enjoying the best of pictures. I have yet to see any LCD that displayed a picture as good as a decent Panasonic plasma especially the professional PH range.

Better PQ and Black levels? Are you feeling alright? :eek:
