I'm having an issue with my 7950 when using a second display in clone mode, where the secondary display constantly produces what appears to be artifacts. The most notable of this is an almost constant screen-tear-like effect on anything in motion (video, games, even scrolling in a browser, etc), very much akin to normal screen-tearing when not using vsync. However, it's a little bit different than normal tearing, since the tearing always occurs in the same location on the screen. There are other issues as well, such as the image "shaking" at times, as well as the display sometimes losing the connection/gaining the connection back in rapid succession.
My primary display (Dell U2311H) is connected via a Mini-DP -> DP cable, and I've tried all manner of connections on the secondary display (Samsung LNT4061 TV), including straight HDMI, DVI -> HDMI cable, and Mini-DP -> HDMI adapter + cable, all with the same effect. I've also tried running the output from the card into my Denon AVR with those same different cables, which then outputs to the TV, and still get the same results. That eliminates any bad cables.
Should also mention that the issue is not with the TV itself, since I can set that as the primary display, and then get the same errors on the Dell monitor with it being the secondary display. And if I use only the TV by itself as the sole display, everything is perfectly fine.
I've also tried a number of different drivers (currently using 13.3beta), and no luck there either. The closest thread that I can find with a similar is issue is here, but I am not running Eyefinity and have tried using both Mini-DP connections on the card (which was the apparent fix found in that thread).
Anyone else having this issue, or able to provide some advice or other possible fixes?
