I just upgraded from a 1080p monitor to a 4k monitor and when I load up phas and try to change the resolution to 4k, the highest resolution option that it goes up to is 1920x1080. I've updated my graphic drivers, restarted my PC. the display settings are setting to 3840x2160 and scaled to 100%. any help with this would be much appreciated!
