I have connected my pc to my Yamaha V675 receiver, and the receiver to my tv. Both connections are hdmi. I get fine sound from the receiver when I play music on the computer, but the video is another story. The only video that shows up on my tv is the wall paper on my computer. Previously, when I ran hdmi directly from my computer to my tv, the tv mirrored every thing I had on the monitor. Now, I just get wall paper. Is there some setting I should change?
