My 30" Toshiba has the bars on the sides. I didn't realize it at first, because I had the aspect ratio set to 16:9 (but chopping off the top and bottom of the screen), but I can't change the bars on the side to anything other than WHITE.
It's very annoying, at least for me. The wife doesn't care. I wish I had figured this out while I still had the option to return in. Shame though.. because the picture is nice otherwise.
