I have 2/3 monitor setup
nr #1 - 5120x2160 (21:9) AKA "5K"
nr #2 - 1920x1080 (16:9)
nr #3 - 1920x1080 (16:9) - connected and used only occasionally
It`s messy. Default resolution detected by system for #1 is 3440x1440. After switching to the full native resolution of "5K" it looks way better but UI elements and text are uncomfortably small.
When I change scaling for #1, #2 is changing as well :/ Also, I'm glad to see Fractional Scaling build in Gnome Display Settings but it's buggy in my case:
#1 set to 150% scaling - as you can see in this screenshot (although it doesn't reflect the problem 100%) its messed up. On #2 I can go only to half the height of the screen where the top bar is being displayed. Wallpaper is messed up. It's unusable.
Wayland is unavailable for me since I use Nvidia GPU. I wouldn't like to lower my resolution on #1 as a workaround.
So my question is:
How to set up #1 to 200% while keeping #2 (and #3 at some occasions) at 100%.
