Hi there. I had been using a LG 34um58-P monitor on a GTX 960 with a hdmi-dvi cable with no problems at all. Today I bought an RX480 and for whatever reason, I cannot select the native resolution, 1920x1080 is the max. Cable is the same, it's a dual link DVI-D on one end, and hdmi on the other.
I've tried to uninstall/reinstall monitor and vga drivers, but it's still acting up.
Googling it up hasn't really given me any help either. Save me please from throwing money at more cables and having to recable my wall mount and desk again.
