black bar reverse burn in

I have heard that you must incorporate the entire viewing area of a tv screen(ie:no bars anywhere-top or bottom)or else the screen will be damaged over time.This occurs because part of the screen is constantly being used and part is not when you have bars present-thus the part that is used/colored gets worn out sooner.Supposedly,this is why ESPN puts grey coloring in there bars when broadcasting in HD.Is this true with all new tv sets or just a certain format-DLP,LCD,CRT,PLASMA?Can anyone confirm or deny this rumor?I personally dont like the zoom and stretch philosophy of viewing in Hi Def.

that would be impossible to do. Some movies (mostly sci-fi, action, older movies) are not in 16:9 like the Television, and have thin black bars on the top and bottom (I think the ratio is 1.33:1, I could be very wrong). Stretching that image to fit your screen would result in a blurry mess, due to having to zoom in.It should not be a problem. I think people worry about burn in too much. Burn in does occur on some sets, but it takes years before it actually becomes a problem, and by then, you would be ready to buy another television. Older plasmas had a problem, but new plasmas deal with it much better. As far as ESPN, leaving the same image on the sides is the same as having black bars. I think they do that, to let viewers know that they are watching the HD broadcast.

Watch your movies and 4:3 SD channels to your hearts content.

This whole burn-in thing is getting ridiculous. I have had more TVs(CRT) than I care to count and NONE have ever had burn-in. It takes literally months of the same image being on the screen 24/7 for the image to burn in.

BTW, RPTV LCD, DLP, LCoS do not burn in. They use a lamp. RPTV CRT can burn in, but only over a very long time. Plasmas are the same way as. People are stressing about something that will probably never happen.

I think in most cases you're right, however my Panasonic crt rptv that I purchased in 2004 had burn-in from a network logo on a news broadcast that I watched for about 40 minutes or so every morning. And this happened in spite of my changing the aspect ratio occasionally in an effort to make sure this didn't happen, and the fact that the logo was not on the screen during commercial breaks. And I find it ironic that I got burn-in through normal television viewing, but got none at all from my video games which you'd think would be the most likely cause. Go figure.

While burn-in is in most cases an unlikely event, there may still be certain sets that are still quite vulnerable to it. Unfortunately for me, my set must have been one of them.
