I’m using pop_os and I desperately want scaling to work and it doesn’t.
I’ve found this works well across high and low DPI machines.
I usually prefer 2x scaling on a 4k screen, and then pictures and text are unscaled. I like being able to put a 1080p movie in the upper left corner and a reference webpage below that, then a big text editor to the right and 'work'.
Gnome programs work perfectly. Qt looks good when wayland backend is force enabled but it causes crashes in certain situations so it's choice between slightly blurry text and occasional crash. Firefox works well, it used to require an environment variable not sure if it still does. Chrome support still not there, scale is correct but text is blurry.
Why would you be looking up and down?
I just find it simpler to have 1 high resolution screen where I can put high def content side-by-side or in quarters on screen.
For now this works, but in 10 years when movies and web pages are 4k by default I'll need an 8k laptop screen (haha)
(Probably at 17" though)
When I am working I only use one screen, and only one window in the screen, and instead I constantly switch between virtual desktops, to the point where I just think "browser", "editor", "terminal" without even perceiving the keystrokes.
However, for gaming I dream of having one of these ultrawide screens that have the resolution of 3 normal screens side by side. Something quite complicated to have in a laptop, but I have seen some attempts.
