I have had this card a number of years and used a 1920x1080 monitor. I just bought an AOC 2560x1440 display and it doesn’t show anything above 1920x1080 resolution in W7 or AMD Catalyst Control center (2015.0804.21.41908). W7 "does" see the new AOC display via it's display settings. This seems a basic issue and I'm not a gamer; just want higher resolution. See the post from AMDMatt about peak optimization and Crimson/Catalysts Beta drivers, but seems I shouldn't need to do Beta for a basic resolution issue?
Connecting via HDMI.
In this spec, It says it’s supposed to do:
2560 x 1600
The HD6xxx series has reached peak optimisation and been moved to legacy status, there will not be any further driver updates for your product. More information available here.
The latest Crimson driver for your system is 16.2.1 and is available here.
The last Catalyst driver for your system is 15.11.1 Beta and is available here.
Any help would be greatly appreciated!
