jwm,
All tv's will burn over time. Some just happen to burn real fast and that is normal projection tv's.
Sheik:
From my reading, DLP's and LCD's cannot suffer from burn-in because there's not the phosphorus coating on the screen to be burned with use. That's a problem with traditional CRT's and Plasma.
Let me cite a source with respect to burn-in and LCD's. This is from
http://www.cheap-plasma-tv.com/plasma-tv-vs-lcd-tv.htm and since the following admission goes against their commercial interests, it should carry particular weight:
"Screen Burn-In Effect
Here, LCD TVs have a marked advantage. Because of the liquid crystal technology, there is absolutely no risk of images burning in from prolonged viewing, resulting in an after image 'ghost' effect. The lack of burn-in risk of LCD TVs is helpful when watching shows that have a common viewing pattern (such as a news or stock ticker, or video games). However, many Plasma TVs include a screen saver function to help minimize the risk, and some of the newest Plasma TVs include clever technology to very slightly move static pixels to minimize, if not remove, this risk."
I'll cite just one more source and then leave the topic alone. See
http://forum.pcvsconsole.com/viewthread.php?tid=3850&page=2
"...Modern CRT direct view, CRT rear projectors, and plasma displays can suffer from burn-in. That's when you see a permanent "ghost" image in areas that have had constant use. Most modern units, though, drive a faint gray signal to unused areas, which minimizes burn-in a bit. Others will stretch or squash an image to fill the screen, which simply looks weird to my eyes. However, DLP and LCD front and rear projectors don't suffer from burn-in at all. This is great if most of your viewing is in one aspect ratio that's not necessarily the TV's native aspect ratio. For example, my daughters will probably watch a lot of standard definition TV, which will be 75% of the use. I'll be using it for DVD movies, HTPC experimentation, and wide-screen gaming the rest of the time."
Over to you Sheik.
