AOC AG275QZ/EU not detected correctly with Radeon RX 7900 XTX
My new monitor AOC AG275QZ/EU is only detected as being capable of 240 Hz refresh rate and no vrr capabilities. See connector 0 in the drm_info.txt. My old monitor is detected correctly with 144 Hz and vrr on connector 1. When switching to HDMI the AG275QZ/EU also supports vrr, but only 144 Hz, which is correct according to it's specs, therefore I don't think it's an issue with the monitor settings. When switching from DP 1.4/1.2 to 1.1 in the OSD, it only supports 60 Hz and no vrr. All other settings don't appear to make a difference. It should be detected as being capable of 270 Hz refresh rate and vrr according to https://aoc.com/us/gaming/products/monitors/ag275qz
