Hello, For several weeks now I have been having a strange problem. I've been connecting my asus laptop (win7, radeon hd4670) to my tv via hdmi. However, recently, after anywhere between a few seconds to several minutes the display will disappear on the tv (no message or anything, just black) but the sound will remain. If I turn off the tv and turn it back on the display will reappear, only to have the problem repeat. Its not the tv, tried other hdmi devices. Not the cable, used other cables. I've reinstalled the latest catalyst drivers, didn't help. Any thoughts? Thanks in advance.
