i have a Mitsubishi TV Model WD-52327, I am trying to connect my computer to my TV using DVI. when I turn on the computer, and windows start up, a message shows: "NO 720p - CHANGE OUTPUT TO 1080i FOR HD". I cannot even see the desktop to change resolution seetings. At the moment I am using S-video, but what will be the best resolution so I could use the DVI Cable?
