Hey there.
First of all, i do run with dual monitor setup, and a Asus HD7950, non OC.
Recently i have experienced a weird flicker kind of thing on my sec. monitor. First, i thought it was my 7950. I did a quick gfx replacement with my, last known working HD6970, and ofc installing necessary drives for the card. But still the same.
By accident, i found a solution. Every time i reboot into windows, i need to reset AMD Overdrive, and the flicker stops right away.
And again, i have not overclocked my card, not even changed a thing in the AMD software, but a reset of the Overdrive settings fixes it, until next reboot.
Installing drivers 10 revisions back or Windows update, still the same. I do use DDU in safe mode for uninstalling drives.
Anyone dealing with the same issue?
Best regards, Alexander.
