I am wondering if this has something to do with AMD Catalyst 12.4. I just recently upgraded to this. In the past I could run my HTPC and simply leave it on. There were never any "No Signal" errors on my TV screen. In the previous post I noted that when I run my AppleTV, I don't get any issues. Could there be a setting in AMD Catalyst 12.4 which cuts the signal after a certain amount of time?
Thanks
