I have a 600m with ATI 9000m 64mb video card. I recently got a 15' VGA cable so I can hook it into my LCD HDTV, which has a max resolution of 1366x768. Ive noticed that the cable is missing a prong and does not support DDC, which is the info about the LCD so the video card can set up the right resolution. The only resolution I can set it to is 1280x786. The only way I can get it to the max resolution is to plug in my other vga cable from my lcd monitor. Is there a way to customize a screen resolution? Problems that cannot be solved: I cannot return the cable and get a 15' cable with all the prongs I cannot find new video driver for the 9000M on the ATI website for Vista
