the game on PS3 is what 663p and on X360 its 720p the PS3 version is not even HD. and who said i got a 20" monitor lol. and on PC version you can set your own resolution. so i could get better than 1080p if i wanted to

that explains it right there. and on pc you can turn the graphix up all u want if ya pc can handle it. so ur 42" 1080p tv is pretty much doin nothin for GTA since its at 663p or 720p.
