I have my PS3 hooked up via HDMI to my LCD which is capable of 1080p, but, the PS3 will not display 1080p for some reason. It displays 1080i on the main menu screen and switches to 720 when I play games. When I set it manually to 1080p the picture looks a little distorted. Could it be the cable? If so, anyone have any suggestions on a good one? Also looking for a good optical audio cable.
