I have a 1440p screen on my laptop; with 1x scaling everything is too small and with 2x scaing everything is too large. So on Xorg I created a 4k resolution and used it with 2x scaling to get to a comfortable size. However, applying 3840x2160 doesn't seem to work using this tool. I also tried 3200x1800 with similar results. However, applying 1920x1080 works perfectly. I'm not if this is to any relevance, but here's what I've got:

Also, I'm running Fedora. Apologies if I missed something blatantly obvious,
Thanks!
