Refresh rate on a plasma?

[2K2 LS1]

I have noticed that if an image like a menu or somethign stays on the screen for more than a couple seconds and then you go to another screen that image seems to transfer to the next a little. Is this common with plasma/lcd's or do I need to excahnge this one?

[bullitt54]

it's common with plasmas. it's called image retention. it's more noticeable on the first 100 hours on plasmas tvs. when the image gets stuck that's what you call 'burn-in', but plasmas are better than they used to be.

lcd and dlp tvs don't have a problem at all with image retention or burn in.

if it is a new plasma then the best thing to do is put on discovery hd for the first 100 hours you have the plasma to kinda break it in. you want a video source that fills the entire screen (widescreen) and doesn't have any persistent logos or bars. after that you won't really have much of a problem. i still wouldn't play any racing games or anything like that because after a period of time the image can be burned in on your screen.

check avsforum.com for your tv model. the start a thread for pretty much every series of tv so you can see common issues, best practices, and fixes for your tv.

::edit because i think of lots of crap seconds after i post

its common on your cheaper tv's. The higher end ones dont have the issues.

[[CS]ls1haha]

My last plasma was a Samsung and I had the same issue. I just got a Vizio and can only notice it if it has just displayed a bright image and then goes completely black.

On some of the new units, they have a revolving mode you can select where the pixels will continually shift in a circular motion to help cure burn in. A guy at Conn's showed it to me and you couldn't even tell it was doing it.

Tell that to the sharps at best buy. The only tv that has a near 0 rate of burn in is a projo.

There was a website (3rd party dont remember name) that did a test with Half Life 2 from PC to a Pioneer 50" and left it paused for 48 hours with no burn in.

Video games are safe for plasma's. The best looking gaming I've done so far was with a 60" Pioneer. Fuggin bad assssssss. OH and this pioneer gets more games played on it then not. The tv is about 6-8 months old too. PS3, XBOX 360 Elite, and Wii have all been played on it with NO problems.

that was on the Elite screen. I personnally have a panasonic 50" monitor, 10K new. Been flawless for several years now, no switching probs or anything, never has. You get what you pay for for sure. Youll get burn in if pausing tv alot. And actually worse on cheaper plasma's (samsungs included , and vizio worse). Main prob. is they come from factory with brights set up too much, help make the screen look vivid, when its actually killing the tv. Hell they dont care if it last 12 months, and burn ins not warranted anyway.

Vizio VP50 here. I will try some nice hd channels and stop letting the kids watch damn dora on that tv lol :o

that's just stuck pixels. big difference. lcd and dlp for all intents and purposes will not burn in. any kind of image retention that you get on the screen can be fixed by just turning the tv off for a day.

Its still no different from burn in. Thats just like saying you can get rid of burn in with "white washing" plasmas. Still the same effect. You can fix them both. Burn in is pretty much a thing of the past. Well, depending when you bought your tv.

Oh and it wasn't the Elite it was a PDP-6071HD (http://www.bestbuy.com/site/olspage.jsp?skuId=7944843&st=60%22+Pioneer&type=product&id=1152228813286)

Secondly, if your tv did happen to get a bad case of burn-in, ESPECIALLY in a year (as manufactors usually have about that long of warranty) you would be able to get it replaced. I've never seen a plasma returned for being stuck with burn-in... even with 4 year store bought warranties.

[bullitt54]

burn in and stuck/dead pixels are a big difference. lcds work by blocking light. there is not way for burn-in to actually occur on the screen. the light isn't actually created by the liquid crystals. a liquid crystal can be stuck in a certain position so that it only allows through a certain color of light. this will happen at random spots on your screen and has absolutely nothing to do with how long an image has been displayed otherwise they would come in large groups when you left a game paused for a long time.

in plasmas the phosphor actually because etched to the glass so that it actually retains the image it was displaying. they have new pixel shift technology on tv but this didn't really cure burn in either. if you are playing a game with a large red box always in the top right hand corner and shift the pixels around by 4 and the box is 50pixels by 50 pixels then you are going to have any area of the image that never changes. it gets burned into the glass.

LOL, show me a manufacturer that will replace a plasma with burn it, read the damn fine print that us dealers actually get!!!!!!! Burn in is NOT a manufacturer defect. Any idiot that thinks it is needs a brain

Ummm no the phosphor does not become etched...


Plasma displays also exhibit another image retention issue which is sometimes confused with burn-in damage. In this mode, when a group of pixels are run at high brightness (when displaying white, for example) for an extended period of time, a charge build-up in the pixel structure occurs and a ghost image can be seen. However, unlike burn-in, this charge build-up is transient and self corrects after the display has been powered off for a long enough period of time, or after running random broadcast TV type content.

LCD type displays exhibit a similar phenomenon, although the mechanics of the image retention are different. In the case of LCD displays the liquid crystal molecules, which rotate when energized and allow the white backlight to pass through the color membrane, lose their rotation elasticity. In this case they are unable to fully return to their normal rotation state when de-energized. As in the case with plasma displays, this is usually transient and will self correct after a period of off time or dynamic content. However, in severe cases it can become permanent. Also see: LCD image persistence.

They are essentially... the same thing.

I think that it is so funny when people talk about burn in and refresh rates with plasmas and lcd tv's. I have been selling TV's now for 8 years, and plasma by far has a better and more realistic picture over plasma.

Plasma will not burn it unless you pause something on the tv for like a week and even at that you notice that it goes away over time. I have a Panasonic plasma and a sharp lcd, my panasonic has a better picture than my sharp when playing Xbox 360 and the sharp has a better picture when watching movies.

Plasma doesn't have a refresh rate like lcd's do because of the technology. If you were to play need for speed a plasma is going to look better and move faster than a lcd will. Lcd's play catch up most of the time.

I'd choose a plasma anyday over a lcd.

They wont replace one with burn in, but if image retention happens they will.


I like you have to try to belittle someone to try and get your point across. :cool:

DLP will NOT burn in at all. There is nothing is a DLP tv to "burn" all they have is a 132 watt bulb, color wheel, and a processor with millions of mirrors.

No way to get stuck pixels,there isn't any. Also there is no phosphor to get burned.
