I have never hear of this before....i won't believe it unless some says yes...
I read this this on the AVS forum...
"Sony 61HS RPTV that has a true 16:9 mode when fed a signal of 480P or 1080i on it's component input"
When someone asked, why no burn in?
a reply:
"The reason there is no burn in is because it is truly squeezing the whole scanning area of the CRTs into a smaller projected area. In other words, what is happening is that the CRT has, let's say, 600 vertical lines (that's not the right number, but use it). When you see a 4:3 image, you get 600 lines covering the entire screen height -- pretend its 30 inches tall. When you switch to 16:9, the "squeeze" is done in the optics of the set and those same 600 lines are squeezed into just 20 inches of screen height.
It is the phosphors on the CRTs that can burn in, not the screen itself, which is just a projection surface. Because you use the set with all the lines all the time, there is no burn-in risk. Nice, huh?"
