on my pc there is a hdmi port and i know it works because i have connected it to my tv befor. i am currently using a dvi-d cable and decided to get a hdmi to dvi-d cable to see if it is better quality. i know that the cable works because i plugged my ps3 into a pc screen using it and the picture is great. the only problem is when i put the hdmi end into my pc and the dvi-d end into my screen and turn the pc on nothing comes up on the screen. do i need to go to controll pannel and change settings or somthing?
