I find it difficult to believe that there isn't a GUI for changing the scaling for multiple monitors, but I am prepared to use randr
if necessary.
I have a new 3840x2160 monitor which I've placed alongside my existing 1920x1080 monitor. If I leave scaling as is then the 1080p monitor looks fine but the 4k one is terribly small. Vice versa for setting scaling to 200%.
How can I fix the scaling to work for both monitors? I adapted this solution with my own resolution but received the following:
$ xrandr --output HDMI-A-0 --mode "3840x2160" --scale "0.5x0.5" --crtc 1
xrandr: Configure crtc 1 failed
If I leave the --crtc
argument out then xrandr
just misidentifies the monitor, like so: xrandr: Configure crtc 2 failed
.
What can I do to get the expected results? Mac just does what you would expect and automatically fix the scaling for both monitors.
