Windows 11 - Advanced display options problem

I found this problem with windows 11.

I press on the desktop right click, and then display properties.

Then i scroll down, and go to advanced display.

There is a button there, that says usually 50hz on it.

I hold the CTRL button on the keyboard, and i click on 50hz button 4 times.

and the screen goes black.

can that be fixed. i am not sure it broke something.

also all drop down menus in windows 11, they go invisible if you ctrl click on them 2 times.

for example, landscape or portrait drop down menu. if you hold ctrl and you click on it two times,

it becomes invisible. after you open it again, then it works.

can someone get this fixed.
