Hi, As the title i have an HTPC with ATI Radeon HD3450. it has DVI-I (is that correct) and VGA. I have VGA to a Samsung T240 Monitor and DVI Straight to a SIM2 Projector. Now im wanting to do all my Video switching through the Receiver,so i purchased a QED Qunex DVI-HDMI cable which i have connected from DVI on HTPC to the HDMI in on my Pioneer 1017av and a QED silver reference HDMI-HDMI cable which is connected from monitor out on receiver to the Projector. I cant get a signal!! Ive tried the DVI-HDMI cable straight to Monitor and Projector and it displays signal fine. Ive also connected a Samsung HDMI dvd player to the Receiver and it switches to the Projector. So i know the QED DVI-HDMI cable works,the QED HDMI-HDMI cable works,the Receiver will switch an HDMI signal, Just wont from the HTPC. The HTPC has a gigabyte 780g motherboard with hdmi built in but it stopped working a while back and i never got it working again,hence why i purchased the HD3450. Now am i missing something,or doing something completely wrong!???? HELP!!! Any input greatly appreciated, Thanks. Andy.
