Change screen SIZE (not resolution)

I have a projector that i cant change the screen size, but… i was using Android TV, and there you can change the size of the screen. Now, im trying to use a computer with Manjaro to acomplish the labor of the Android TV.
But… how i can change the screen size?

Hello @9acca9 :wink:

You can use xrandr when using xorg on Gnome, if the session type is wayland, then there would be no other way than modifying the EDID of the monitor.

xrandr --fb 1920x1080 --output VGA

:notebook: This will create screen which should fit the monitor. If it is larger it will be outside of the visible space.

More info: man xrandr
