Hi folks, Reading the manual for my new Panasonic TH42PE50B and something is puzzling me. In the set up menu, there is an option to "highlight" the side panels when viewing 4:3 or 14:9 images, in order to prevent any possible "after-image" or "screen burn". I can understand why they have this and seeing as I NEVER use 4:3 or 14:9 mode, it shouldn't be a concern. However, obviously when you watch a 2.35:1 aspect ratio DVD, you still have black borders at the top and bottom of the screen. So, if I watch a lot of 2.35:1 movies, should I be concerned about possible screen burn???? I cannot see what the difference is between having black borders down the left and right of the screen (4:3 & 14:9 modes) and black borders at the top and bottom of the screen (with 2.35:1 movies). Surely if there is the "threat" of screen burn with the borders down the sides, wouldn't there be a similar "threat" with the top & bottom borders??
