i think 1080p is the best. i just got an hdmi cabel and it is by far the best resolution i ever had. for those that dnt know 1080p is the highest resolution a tv can have. any thing under that is ok. i am not going to knock any resolution under that because since i got my ps3 i have been usibg a hdmi cabel that outputted 480p and it was ok but this is just over the top it is so crisp and clear. by the way the tv that i have is a 2inch LG and it is just so friggin cool
