I actually have a Samsung 40in and it fills the screen beautifully at 1080P. I didn't have to mess with it at all! Sitting close does make everything look big, but gaming on it is GREAT!!!!! Like, really great!!!! In fact, when I game on my PC, I switch from my monitor(which recently broke) to my TV. I do have another post though about forcing resolution. I can get it up to 2560x1600 with good quality but I dont want to hurt the tv.
