I have a 27" LCD HDTV made by Viewsonic and at first used it as a computer monitor. I decided to go back to my CRT and use the HDTV just or TV and Xbox 360 games. Just a few days ago I decided to try the HDTV as a computer monitor again. Well, where the HDTV has been dislaying 4:3 TV images the screen is slightly darker than the rest of the screen. Anyone else notice this on their LCD HDTV? It's less than six months old too so I'm thinking of sending it back to Viewsonic as this is unacceptable.
 
I use an LCD monitor in a projector and on very hot days it gets a temporary burnin of things on my desktop. It does the same in games.
The burnin never occurs if playing only films or TV.
It can go away in 1 hour or can take a day depending on the drop in temp.

I have read up a little on this and it appears some LCD manufacturers panels are more prone to it. There are reports of PC LCD monitors suffering the same problem when used as recommended.
Samsung has been named a few times as supplying screens that suffer burnin.
I'm using a IIyama E380-S LCD but havent looked up who manufactured the panel.

Its possible the TV's suffer from the problem more than computer LCD's as everything is made to a price.
If PC monitor LCDs could get to the size of the TVs for the same price, I'm sure they would be for sale. This makes me think the grade of LCD used in at least some TVs is not good enough for PC use / sustained viewing of the same picture.

I'm not sure if this is related to your problem but its possibly caused by the same thing.
I would certainly send the TV back if the burnin doesnt go away.

edit: keep your LCD cool! :)
 
I need to drop in here cause I didn't know that LCD's could get images burned in until I saw one at work with a NEC LCD monitor left on a DOS type prompt over the weekend. It was a nasty one too, but it eventually went away over the next day.
 
OK, thx. It goes back if it doesn't go away. Sending an LCD TV to the U.S. from Canada is expensive too.
 
I wouldnt get the same HDTV after that.
My advice is get a refund then look around at the HDTVs the readers here are using successfully with their PC's.
If they have no complaints after a few months, its likely the burn in is a non issue for the screen they use.

It might be a good idea to make a thread titled something like "Your Big HDTV and PC experience please" to attract more responses.
 
Try searching the forum about burn-in with LCDs. You'll find that most of the problems go away if you leave it off for a couple of hours, and then display something moving over the whole screen.

You've seen those videos that are just RGB, B/W flashing colors (used to detect/fix stuck pixels), right? Download one of those and play it for 10 minutes.
 
No, I haven't seen those but will search for one, thx.

This has nothing to do with using the HDTV for PC use. It's purely caused from displaying 4:3 TV stations. If I play a DVD movie and am up close to the screen I can see the burn in from the 4:3 TV image. I just didn't notice it before becaue I wasn't siting close enough to the screen, but using it as a PC monitor made me see this flaw.
 
There are likely to be many LCD TVs out there with the same problem.
Its hard to find which do burnin easily if what they are used for is always changing (ie not a constant image)..

By getting one that a PC user is happy to use with his PC, you are likely to find one without the burnin problem regardless of what you really use it for.
 
I've found some tricks in other posts that might fix it. One is to leave the screen on with a pure white screen overnight, another is to run the Starfiled screensaver overnight. I'll try those and see if it fixes it.
 
You might also try this utility: Dead Pixel Tester . Use the "auto cycle" setting and right-click outside the menu to hide the menu box. Let this run overnight and see if that doesn't fix the problem.
 
All right, try those two (three?) fixes to see if they work.

I should have clarified earlier: most reputable (read: non Wal*Mart) brands won't have too much of a problem with burn-in. I have seen extreme cases of burn in with things like the LCD displays in the Terminator ride at Universal Studios (constant spinning triangle for years? yeah, it has burn-in), and on the McDonalds touchscreen terminals (I worked there; when they changed the menu style, we had to get new screens). Most of the "devastating" rumors were people confused between Plasma and LCD when they were just beginning. Nowadays, they should be closer to computer screens with recoverability. Viewsonic has been a so-so brand for me: when they had their first consumer LCD panels, they were horrible. They progressed along enough so that they became a mediocre brand, and now they have the nice "tell-your-neighbor-about-me" models. Every once in a while, though, they come out with something in the budget range that stinks, kind of like Sony.

Care to share the model?
 
This is a very interesting article about the burn in on all types of LCDs
http://www.behardware.com/articles/615-1/lcds-with-persistent-images.html

Interesting to read, right at the end of the article they tested some monitors for days and they didnt exhibit the problem.
One thing that hasnt been mentioned is that the effect is directly proportional to temperature.
Perhaps they tested those Monitors in a colder environment, or maybe there are some that really do not have the problem bad enough for us to see.

I only get burn in on hot days and/or if a fan isnt working.
I can induce the effect any time by turning the fans off, so my problem is definitely related to heat.
(this is using an Iiyama monitors LCD for a projector)

A little airflow around your TV may be all it needs to prevent this happening.
Displaying a white image for a few hours definitely gets rid of it faster, I heated the panel (turned one fan off), got a good burnin and left a white image on it. After a few hours the burnin is completely gone.
 
Yep, that is true as well. Extreme cold slows response time, extreme heat deteriorates it. Mild cold is the best, mild heat can cause shadowing (impermanent burn-in).
 
Thanks for the link to the utility. I downloaded something similar for the PSP but it is just a video and I couldn't get it to display 16:9 with the media player I was using so this one is better.

The Viewsonic model is N2750w. I was going to buy a Gateway 20" computer widescreen LCD but I saw someone post on here that N2750w is good for PC use so I thought 27" for only $50.00 more was a better deal, plus HDTV has a lower native res which gives me better performance in games. Live and learn.

I've still got my 21" Trinitron CRT though so I can always go back to that. Plus I've got a 19" LG CRT for backup. I've had two LCD's now, first being a Samsung, and I still prefer CRT. I just wanted widescreen and is why I got the LCD.
 
I bought this HDTV at Costco and after doing a bit of researchat the AV forums I see I should have no problem returning it for a refund so that is what I will do if I can't get rid of the problem.
