I have an old PC with an HD6670 card connected to a Dell U2515H via HDMI. When I upgraded to Windows 10 I cannot set the resolution to 2560x1440. This worked fine in Windows 7. I have tried Catalyst 15.7 and now 15.10 Beta but I do not get higher resolution than 1920x1080.
Have Googled around trying to solve things with Windows 7 Compability when installing the drivers but no luck as of yet. Do anyone have any pointers?
