144FPS monitor only shows 60?

I got a 144FPS monitor for the new XBox series X. When I go to the menu on the monitor, only 60FPS are displayed, although the Xbox makes up to 120 Hz.

Can I do anything there?

It's a Mag322CQRV Curved monitor

You have to look in the XBOX settings. It is locked there by default

And can that be exhibited?

Thank you

Should.
