LCD: pixel burns possible?

Postposted on Mon Feb 06, 2006 1:32 pm

I finally opened my final 2005FPW exchange and it seems to be on par with my original one in terms of the backlight issue. Found a bad pixel though.

But now I am noticing my original seems to have some burn-in's already when I switch to black using DPB or Logon screen saver. In particular, I have a few icons on the desktop and they seem to be "showing through" on the top left corner. I have switched to try VGA and DVI on both monitors. The new one doesn't have it, so can burns be possible even on an LCD? :o

Please tell me I'm not crazy.

I saw "burn in" on a philips LCD a few years back that was being used at my workplace. it seemed that the pixels were almost stuck "open", allowing light to pass though. One coworker said that with a little excercise (ie. something like one of those plasma screen break in dvd's) the pixels would begin functioning properly again, but soon after we noticed, the screen died anyways, so we never found out.

In short, I have seen it happen once, but I've got no idea if it's common or permanent.

OK, been doing some reading, the technical term for this is "image persistence". I will see if I have time tomorrow to try some of the remedies, see as I will be using the machine for the rest of the day.

What are the remedies, and what exercises? Not that I have a LCD monitor, but it'd be nice to know.

Yeah, I've never heard of it being permanent. But it usually takes longer than it seems to have in your case. Just play some music videos full-screen (or anything with lots of jump cuts and flashes of different colors) and you should be fine.

I have a 2000FP that becomes tired after being on for a few hours straight. I was using for gaming and didn't let it turn off at all (no screen saver either). In particular, game chat windows and toolbars were showing bad image persistence. I noticed exercising the screen would help -- but only so much. I'm mostly using it with desktop (e.g., web browsing, finance, etc.) apps now -- I turned on the blank screensaver and power saving power schemes. If I know I'm walking away from the comp, I'll go ahead and turn it off, too. I think the longest I have it on at a time is about four hours now. This has had a lot more impact than exercising the screen. :-? Anyone else have any luck rejuvenating an LCD?

Well it looks like my 2005FPW is showing signs of image persistence :(

It's clearly from the Windows title bar. Maybe I should blame Microsoft :P
Hopefully I can make it go away.

Use DeadPixelBuddy and cycle through a few colours. If after a while it doesn't go away, do the all white for a few hours then all black for a few hours thing. After that's taken care of, use a short timer for your screen saver. And pick one that does move the image(s) often. I use good old XP screen saver which means I just need the Windows logo to move often enough.

I read that leaving your monitor off for an extended period is supposed to help, but the 2 weeks my monitor was off over Christmas break didn't help at all. Right now I've got an all white background and screensaver. I'll try DeadPixelBuddy and see if it does anything.

It may be the more serious case then (which I ran into). Turn off monitor turning off in Windows Power options, then just set DPB to all white overnight, then switch to black for another few. That did it for me. I think I read somewhere that said you may need to do the all white thing for up to 12 hours or more.

Yeah I'm going to try leaving a white screen up all night, even just having a white background up for a couple hours seems to have helped a bit.

This is really good information. I have a Dell 23" TV that has a really bad case of this. It's rarely on widescreen because I don't have that many HDTV channels here, so it's got a really bad line along the right border. I'm hoping this will diminish it.
