Hello, guys. As the title says I own the kg251qf which is 144hz monitor, but I can't run it on 144hz, the highest option I have in the menu is 120hz. I'm currently using the DVI-D cable which came with the monitor, my videocard doesn't support displayport, so that's not an option for me. I have reinstalled all drivers, changed the ports but nothing worked, still 120hz only. Is there anything I can do to force it to use 144hz? Thank you in advance!
