Can an LCD suffer burn-in?

[zephyrprime]

LCD's can definitely suffer burn in. At where I work, there are quite a few LCD monitors that have the windows login burned into the now. I've seen to first hand.

As for why they might get burn in, maybe the crystals get stuck like some say but ti's also possible that they are getting washed out by exposure to light. A poster left out in the sun fades after a few years, perhaps lcds suffer something similiar. Even without electron guns, there are other ways to get burn in.

I just experienced this with my 2005FPW :frown:

Time to find a good screensaver

Uhh...don't you have your monitor set to sleep after 10 minutes or so of inactivity? This reduces power usage, though it still draws more power than if it was actually off. LCD's are very resistant to burn in though it does happen. However, it takes literally days of the same static screen before burn in starts to set in.

Think about it.. when you are using Windows, the taskbar rarely moves.. say if you work for a few hours on the computer everyday, it adds up pretty fast

This is what happened to my 2005fpw

i have a 32inch plasma TV, and it annoys me when i play GTA SD with the PS2 because all of the objects on the screen (AKA Map etc) get burned in, but when i turn it back to the normal broadcast TV with the motion picture it corrects it. when i turn the PS2 off so the plasma is just waiting for a signal, i can see the objects that looks like they are embossed into a grey tint :|

LCD is the future no doubt.

Hrm, probably different usage patterns. I rarely browse the web for more than three hours tops at a time. After that I'm usually playing a a game or watching a video or editing a video. I also switch to portrait view (I got a 2005FPW as well) sometimes depending on what type of web pages I'm viewing. Taking a 10min break every 2-3 hours and turning the monitor off during that time probably could have prevented the burn in effect though.

nostolgia screensaver is a good one.
but powersaving is also good. why waste power?

just out of curiousity, when your lcd is on power saving, is that similar to turning off the LCD? Would having power saving on when idle for 10mins+ prevent burn-ins?

Dude, just get an Apple Studio Display. They are quality checked before they are even built so you get a perfect display ALL THE TIME.

It's pretty much the same thing as turning off your LCD.

Dude, can't lcds develop dead pixels over time?

yes thats true, some pixels can get stuck on green red or blue over time, there was this software that was used that flashes the whole screen red blue and green for an extended time, this would in some occasions unstick the pixel and have it start working again. My brother did it on his PSP and it had worked for 2 out of 4 pixels


i have one dead pixel on my monitor, it just didnt work out of the box, but its located on the "start" button so i aint that bothered.

My left monitor is a KDS RAD-5 LCD which has had a maximized web browser on it for several hours a day for about 4 years. Even after absolutely no change in the image for a day it has no burn-in at all.

I have a laptop that will burn in if you leave the same thing on the screen for several hours, but it goes away pretty quickly if I unplug it and remove the battery.

Like I said, it takes over a day of continuous static image before burn in starts to set. I think turning the monitor off for a couple minutes every three hours would be enough to prevent any burn in. Our LCD for the surveillance system was left on for about a week. Nobody bothered to turn it off. It was after that time that burn in was noticed.

hmmm, would a screensaver prevent burn-in on an LCD? If yes, what kind of screensavers, all of em?

 

[Ichinisan]

I'm wondering if image persistence in LCD monitors is due to analog conversion circuitry. Can anyone confirm persistence when using a digital interface such as DVI?

Pretty much any screensaver will do the trick. If you want, use Windows' built in screen saver. I have mine set so that the monitor powers down after 10min of inactivity. Right click on the desktop, go to properties and select it, then select the screensaver tab. The screensavers available suck but they take up very little resources and you don't have to install another piece of junk that's sucking up RAM. Plus the main job is to prevent screen burn in and not look pretty.
