Hey guys... I have a Samsung 3D tv 55 inches and I need help on changing it's resolution, mainly because of these blocks that keep showing up on the left and right side of shows that aren't in HD... I know you guys are probably thinking "You don't change the resolution. It automatically adjusts" or whatever, but my tv is being RETARDED! Every HD channel works great, but when I watch regular channels there are 2 BLACK BARS on each side and sometime the top and bottom. My tv is currently set on 1920x1080 HDmi and I think I some how changed it from 720x480 or something like that. Please HELP!!! Thanks!
