I recently bought the XFX R7770 Ultra OC GPU. At first it seemed alright, however I have found that when playing videos on youtube or sometimes steam and a few other places, my primary monitor goes hay wire. (as seen below but flickering and jumping around.)
This happens specifically while the video or ad is playing, after it will sometimes return the primary monitor to normal, sometimes slightly flickering, or a black line down the left of the screen and no cursor appears, or it will just stay in the crazy mode.
This always stays on the primary monitor, if I swap cables out while its in this mode, whichever monitor is becomes the primary, is affected the same way.
I have used the driver finder, and its says I have the most up to date drivers installed. Any help would be greatly appreciated, any further information needed please ask Thanks!
