Hi guys, new to this so I'll do my best. Ok I have Sony Bravia hd tv. An dell xps pc, ps3 and an onkyo av receiver tx-sr605. So I have my ps3 and pc both running hdmi through the receiver to the tv. Now he's were it gets strange. When I put my ps3 on it works perfect, when I flick it over to pc I get a picture of the desktop and that's it. Yes just a still picture... Mouse doesn't move windows key does bring the menu up. It's literally just a picture of my desktop :s any idea?
