I am starting a new thread because this problem has existed since 15.7 and all threads about it have been ignored.
Something changed between 15.6 and 15.7 that caused anyone using 2+ 1440p monitors to experience display corruption when the card is running in 2D clock mode, as seen in the above video.
All the info can be found in the thread link below. In it there are several videos and links to other posts with users having the same issue.
did u resolve the issue ? i m also having these problems since i dont know when... the thing is that in the last week the problem escalated. it now corrupts my whole main screen, but leaves the secondary intact...
