My PS3 graphics do not look how they should. The texturing in games looks very pixelated and not smooth. Objects in games seem to flicker a lot. It has always been this way and I can't figure out how to fix it. I have tried my PS3 on three different tvs and none of the settings change anything. I use and hdmi on an hdtv. All of the settings on my PS3 are correct and nothing makes a difference if I change it. I get the same ugly, pixelated graphics on any game. Could there be a problem with my PS3 or hdmi cord?
