There's a Mac keyboard command to restore screen settings?

So I have a late 2014 Mac mini in Mac os Monterey. I played with my refresh rate on my Monitor and put it to 25 hrz.Now I can’t see the display cause it doesn’t support 25 hrz. It is giving me the message to change the refresh rate to 60 hrz at least. But I don’t know how to do that cause I cant see the screen.Is there anyway to restore it to default with a keyboard command? Pls help me fast. Thank you. It is a Philips PHL monitor.

I don't know if this will fix it but it's what I would do.

Try starting in safe mode and see if the display activates and if it does go to system preferences and change the refresh rate.

or

Try resetting NVRAM

Intel Macs

To reset your NVRAM, you use exactly the same procedure you once used to reset PRAM.

Shut down your Mac.

Press the power button, and as soon as you power up, hold down Command-Option-P-R.

Keep holding down those keys for about 20 seconds. Then let go and allow

your Mac to continue starting normally. If you have an older Mac that

chimes at boot, hold down the keys until you hear a second startup chime.

Then check the Startup Disk, Display, and Date & Time panes of System

Preferences to make sure they’re set the way you want them.

Last night I tried the same with Apple Support too but nothing still the same so I am going to try team viewer. Going to connect it to TV give the code to another computer and then connect it to my display HDMI and from the other computer I am going to change the settings. I did not try it out yet but lets see.
