I recently bought an HD mobile external monitor to use with my laptop. My laptop screen is a 4K monitor (3840x2160), whereas the external monitor is HD (1920x1080). I've been trying to get my laptop screen to 'match' my external monitor in terms of 'sizing' and scaling/DPI.



When I say 'sizing', I mean that when I move my mouse along the top edge of my laptop screen into the external monitor, the mouse appears at the top edge of the external monitor, and the same goes for the bottom edge (in other words, they match in terms of 'virtual height' if that makes sense).



When I say 'scaling', I mean the physical height of screen elements on either screen should match the other.



I have explored other Stack threads that have advised trying to use Wayland, enabling fractional scaling, and manually setting xrandr commands, but alas none of these have helped, and xrandr experimenting in particular has led to a lot of odd and distracting visual fragments.



Is is possible to match both sizing and scaling between these two displays? If possible, I would greatly prefer to do this without sacrificing the 4k resolution of my laptop screen.
