Is it possible to have different zoom for each display for dual-display configuration?

Question

It seems for me like it isn't possible, as zoom is changed for both displays simultaneous in "Displays" tool.
ubuntu 18.04, nvidia, one display 4K other 2K
I want to have 200% zoom on 4K display and 100% on 2K display so "resolutions" are equal

Any suggestions, please?

Answer 1

This should do the trick. Replace $YOUR_4K_SCREEN with the name of your output. You can play with the scaling factor until it's comfortable for you.

xrandr --output $YOUR_4K_SCREEN --scale 0.5x0.5

If anyone knows how to make this persist let us know.

If you encounter overlapping issue on second monitor use arandr to set screen position

sudo apt install arandr

Answer 2

Log out, and log again, but just before use the little cog, choose Ubuntu Wayland. And then in your configuration of screen , you'll be able to select different scale for different monitors.

Answer 3

You also need to turn on Fractional Scaling to be able to have different zoom values for each display

Answer 4

So I was having a similar problem, using Ubuntu 18.04 on an HP Spectre laptop with 2560x1440 at 200% magnification and have an Acer display at 1600x900. I was trying to get the Acer display to not display at 200% in the setting and it would not work. I ended up running this (Thanks dsklosr)

xrandr --output HDMI-1 --scale 2x2 

and now have 200% magnification on my laptop display and 100% on my attached Acer display :)

If someone knows a sudo command to make it permanent I will be all set
