OK, this might not light up the forum BUT, A friend and I were having a debate over how burn-in proof a direct view tv is vs. a RPTV. Can anyone one here help win this bet ? Is a direct-view more burn-in resistant ? Is any TV burn-in proof ?
I guess this debate would be really moot if the TV universe just went 16x9 ! But alas, as long as there are two screen formats and beer to drink, we have these debates !
I would rate the TV's from most susceptible to least susceptible to overall damage, as follows:
Plasma
RPTV
Direct View
LCD
DLP
On the first three it's uneven phosphor wear. On the LCDs it has to do with "black level". DLPs have little or no concerns from what I've heard.
The first three are really about even, depending on how you adjust the contrast, brightness, whether the plasma has automatic settings to prevent burn in, etc.
Perhaps you're both right and should buy each other a beer.
PS, even in the 16:9 universe, you have to concern yourself with any static images - ticker lines left on TVs forever, games with static images, heavy duty network logos, etc. These are not typically as large a problem as a 4:3 image on a 16:9 set, since people tend to vary their viewing, however, they are issues to be aware of...

You know, it really is about time someone launch a campaign against networks that put logos on the screens. Even the translucent ones will burn in - the image is continuously brighter or darker (depending on the actual image) than the surrounding screen, therefore will lead to uneven phosphor wear. Is it really that hard to press the "info" button on your remote to see what channel you are watching in the event that you forget?

Well I guess I know why neither of us were winning the arguement !!!
Meanwhile I agree with the logos in the corner... I don't even notice them anymore, yet there are still there... eating phosphor

I would have to agree with that order of burn-in risk ... However, I was told by some engineer on AVS Forum once that PLASMA is actually low risk and should be placed somewhere between DLP/LCD/DirectView as for as burn-in risk ... who knows! Let's all buy one of each of these HDTV's and leave our PS2/XBOX on the title screen for 30 days and come back and see what happens! :D

The logos aren't displayed during commercials which seem to occur every five minutes!It take time for burn in to occur.When is a logo onscreen for more than 30 continous minutes?

Not to stray off topic, but it was always my assumption that broadcast companies stick their little logo "bugs" somewhere in the picture to annoy those who prefer to record stuff from OTA broadcast and place it on a VHS/VCD/SVCD/DVD. Look at any of the stuff you download off of the internet or from P2P programs such as Kazaa, you'll usually see the little "FOX" logo in the corner of programs such as Futurama or the Simpsons.
I believe this little tradition originated from Europe. I can remember watching movies on OTA broadcast in France and they would occasionally pop up with a logo "bug" during the movie...of course they RARELY show comercials during movies shown OTA. I watched the entire dubbed version of Predator with only one commercial break!

I agree about the logos. Just set up my TV yesterday and there was a big sticker on front of the TV warning about continuous TV logos. Then tonight I was checking out the Comcast HD channels - our local PBS channel was featuring a 2 hr movie all with a WETA logo in the bottom right. It was the first thing I thought of. Why can't they get rid of them?? :mad:

I agree totally that the logos and the scrawls on the bottom of ESPN need to go. Even though there are plenty of commercial breaks in most programming I am still concerned about burn in. How long does it take to be a concern? Hours, days, weeks? Does my short attention span, channel surfing syndrome help protect my set? How much of a concern is burn in for the average viewer?
As long as the same static image doesn't stay on your screen for more than about 15-20% of the time, you should be OK. This means that the average viewer has nothing to worry about, as long as you don't watch 4:3 continuously on your 16:9 set...
