First of all, I can't seem to be able to make screenshots anymore, never happened before. So all my pictures are actually photos, sorry.
I'm running Windows 10 Professionnal 64-bit.
My graphics card, HIS HD 7970 IceQ X² GHz Edition, has my Samsung PC screen plugged into the DVI port and my Philips Flat TV plugged into the HDMI port.
When I'm watching my PC screen, it displays this: http://i.imgur.com/63IaYfS.jpg
When I'm in "Extended Mode", I get this on the TV: http://i.imgur.com/OccuhPU.jpg which is normal.
But when I'm in "Duplicate screen Mode", I get this: http://i.imgur.com/WULrzlM.jpg but my PC screen keeps the normal colors.
I tried uninstalling the drivers, rolling back to 15.30.1025.1001-151204a-298676C, changing "HDTV settings" in "Advanced Radeon settings", nothing fixes the problem.
I'm currently installing the Beta drivers to see if it changes something.
Is there a fix?
