Q:

Low resolution stuck aften pressing win+p, what does win+p do?

My screen resolution got stuck after I pressed win+p. I don't know what that key combination does and would like to find out? I've looked at setting -> Keyboard -> shortcuts.
To resolve the resolution issue, I've simply disconnected the monitor from the device, reset the device and then connected the monitor back to the device.

A:

So pressing Win-P enables Mirror displays, which in the settings and Display section it says: Note: may limit resolution options. I did it to test it and it took all screens to 1080, normally they are 2K or 4K.
