I will admit, have never seen you monitor before. But looked up in Google and found this. Hope this helps.

1 Press and hold the power button for 5 seconds. Then a menu should appear...
2 Press and hold it until it is over AUTO. Then tap the button once.

Let us know if it helps. It would not break your monitor to do the above. But be patient and follow the above simple procedures. This could help others same as you.

Depends of what seems to be a problem.
If you want to get rid of that message box, appearing by itself, then probably you need to take front panel PCB with buttons and replace "Auto" one, 'cause it's stuck.
If you want to unlock an Auto Adjustment and other functions in your monitor, then press and hold 'Enter' button for 5 seconds.
