I am trying this on a Radeon 9600 XT, which has both VGA and DVI. The reason I was trying the DVI is because I have a new computer on order with a 8800GTX, which only has DVI. I have tried a different VGA monitor and had the same result, but I don't have access to a DVI one. My PSU is 450 watts, and the adapter came with the current card, and has never been used. the odd thing is, when i pull the monitor from the VGA, i get the cable not connected message on the screen. i plug it into the DVI with the adapter, and that goes away, but the monitor stays in its off state. does this mean anything?
