I have a problem with my monitor: I have an AOC G2260VWQ6, which supports freesync and 75hz, but I can't enable freesync, because it says "freesync not supported" in AMD display settings, and when i go to advanced display settings in windows, there is no option for 75hz. (I have an RX 580, and I use an HDMI cable that supports 1080p 144hz.)
