Since installing a Q6600, my DVI to HDMI cable no longer displays a picture on the Panasonic HDTV I connect it to (TX-32LMD70). VGA to VGA (with a DVI adapter) works fine, but I don't have a VGA cable long enough to use, I just used a short one to test and I'd rather not buy a new cable. I've tried with two different DVI-HDMI cables and it's the same.
I've extended my desktop and I can feel the space, I can drag things over, etc, but there's just no picture on my TV. I've tried both HDMI1 and HDMI2 channels on the TV. I've also installed the latest CCC in case it was a driver error or something. My video card is a HD4850 1GB and I'm using XP.
I can't understand why it isn't working - I've used this cable for a good year now and it's been fine. Why would installing a new CPU make it suddenly not work?
Cheers for any help
