I have just bought a second AOC Q3279VWF monitor and I have the two connected to my PC (Win 10/64 Pro) which has a Radeon RX460 graphics card (2Gb), one via a DVI-D lead and the other by an HDMI to DVI-D. I have successfully configured it as dual 2560 x 1440 res displays but I was getting a problem with some snap issues (which turned out to be an AOC software thing). Since then my displays have become a maximum of 1920 x 1080 and I can't seem to change that.
I know the system will work at 2560 x 1440 and that is what I bought the monitors for so can anyone tell me how I can override the system or whatever I need to do to get back up to full res?
Thanks in advance
