I have a AMD Radeon R5 200 Series videocard. I use 2 screens - a 27 inch and a 23 in in extended desktop mode.
The screen that is set as the primary displays fine, but the one set as secondary is rather dark and white is not really white.
I tried using a different screen, bought new cables, switched from hdmi to dvi,tried toying around with the monitor's OSD to no avail.
only known suspect left is the videocard... and yes I updated meanwhile to the latest driver
anyone who can share at tip on how to correct this ? Kinda annoying..
