My Acer Nitro XV273K is stuck in 144 Hz mode. How do I disable it? The XV273K was an early 144 Hz 4k monitor and it enabled 144 Hz by using two Displayport cables. I was running it in 120 Hz mode on a single cable. Now I have the monitor attached to two separate PCs and find that the monitor is stuck in 144 Hz mode. If I go into the monitor OSD settings when I get to try to modify the entry the OSD just disappears and the screen refreshes. I want to set it back to 120 Hz mode. How do I fix this?
