Turning the monitor off and on again changes the refresh rate to the correct value. However it's still locked at 60hz when the system is rebooted. I have the same problem with a Gigabyte FI32Q monitor, I'm also on Archlinux and the problem started when I upgraded to 5.27.4. On my monitor it's 170Hz that works, on all others (120,144,165) the fps meter on my monitor and the kde one under desktop effects shows 60 fps. Powering off and on the monitor also fixes the problem on my system. Additional observation: if the screen goes into sleep mode then turns back on, it goes back to 60hz. But powering it off and on after that fixes the problem again. Same for me on Dell S2721DGF since 5.27.4. When I select 120hz and 144hz it stays at 60hz. Switching display off/on is a temporary fix, but after reboot it is back to 60hz again. When I select 165hz it works correctly.
