Try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up. If that doesn’t work then go into the monitor’s menu and do a factory reset.
Check your monitor and cable on another PC as a double check to make sure that the issue is not the PC. I am fairly sure that this is a monitor issue. Try a "feel" test of the monitor buttons to make sure that the buttons aer not faulty.
