I think I might be going crazy. I'm watching some tv now, and it's on 'full' mode. Apparently, 16:9 tv shows in 'full' mode are supposed to be viewed in its original size. But I'm getting vertical black bars on the left and right side of my TV. Isn't it supposed to fill my screen if its broadcast in 16:9? Also, the 4:3 shows are filling the screen. Could it just be the program I'm watching?
