The goal was to use my new TV as the display for my old Dual 800 and a wireless keyboard and mouse. So have conected by Dual 800 to a Sony LCD projection TV using a DVI cable. This was not small achevement and I asked for help in a posting entilted DVI Cables. First I needed a ADC to DVI converter. Then I discoverd that ther are 2 types of DVI conectors and the cable I purchased was of course the wrong one. But finaly I got all my M into F and fired up my computer. All seams to start fine and the TV displays the grey screen with the Apple logo in the middle. Then the screen goes black and that is the end of the story. SO I NEED SOME HELP. I think I might have the resolution settings set incorectly but I do not have a nother display at home to plug in to check or change them.
