Static lines on main monitor?

post #1 of 6
Thread Starter 
I have owned my 7950 for a few months now, and I have noticed a problem ever since I got it (see pic attached)




This occurs every so often when I try to play a video either one that is already downloaded to my computer, or load up a video on chrome.

It has never happened when gaming.

I also have a second monitor, but nothing never happens to it. I can still move the mouse on that monitor and everything still works.


Could this be driver related (I have tried at least 4 drivers), or maybe an OC problem? (I have had it OC'd since day one and nothing came up when I stress tested it, but after this last one occurred, I toned it down a bit). Also it's not heat related as my card stays in the low 30°C range.

I'd say return the card to stock clocks to see if it makes any difference. First thing that came into my mind was that the video engine, or something related to it, is misbehaving, since almost all modern programs use the GPU to decode video, so if the video decoding causes this, it would clearly point towards the video engine on the GPU. However, it could be just a driver/software issue. Also, this sounds funny, but do the "static lines" get captured on a screenshot (printscreen & ctrl-V in paint)?

Also, what happens if you switch the monitors around, so that your "primary monitor" becomes secondary and vice versa (swap the ports on the gpu), and then try opening a video, do the "static lines" follow over with the monitor, or is it just "the primary output" that gets these?

Good question. I will leave the OC toned down but not stock for now, and if it happens again I will try to screenshot the problem, and switch the monitors around. If it happens again, I will return to stock and update this thread.

Drop it to stock.
Dont just tone it down.
Seriously.
All you are doing is adding another step to troubleshooting and making the process of narrowing down the issue take longer.

Stock on a 7950 for a few days isnt going to kill you.
I manage to run my 480 at stock most of the time and Im still alive.

Go into Catalyst Control Center as shown and disable some of the video enhancements to see if it fixes anything:
