Hello, I'm connecting my grapic card with HDMI cable to my new LG HDTV (37cs560y). The problem is that I can't raise the resolution above 1280x720. Also. picture and video are in very low qualiy. I'm sure that the probelm is with the graphic card HDMI output. I know this because I've connected the TV to another computer (with a low budget grapic card) and everything worked fine.
