Xorg has a lot of accumulated hacks that make scaling work ok-ish. It falls apart when you have multiple monitors with different scaling, but for a laptop, just close the lid when you dock it and it should be good enough. Wayland, after much feet dragging (why this wasn't a day-1 feature for a supposed Xorg replacement is beyond me), finally managed to cobble together basic support for non-integer scaling [0], so it should finally Just Werk (tm), regardless of if you scale at 2x, 1.75x, etc. without looking like a blurry mess. I don't have experience with 4k displays in laptops, but I will say this: considering AMD's ongoing problems with idle power draw on >120 Hz displays [1], I'd recommend not getting the 165 Hz display if you're getting an AMD CPU.

> It falls apart when you have multiple monitors with different scaling Yeah that's my colleagues! This is why half the monitors in the office are not being used :D. Someone thought it was a great idea to get three or four 4k screens but only one person actually wants them; everyone wants their laptop as a second or third screen. (Personally I'm a single-screen type of person anyway, but what made me commandeer a 1080p screen is the very noticeable lag that my 2018 i5 Lenovo had when trying to drive a 4k screen with or without display scaling. Got a new work laptop now that ought to not have that problem, but I haven't bothered trying yet.) Anyhow, thanks for the pointers! Especially that 120 Hz AMD thing sounds like a big caveat.

  Running an xrandr script with ’--scale’ when you plug in the externals works okay for me. I have a 4k laptop monitor and 2 X 1k externals. It's perfectly fine for work use cases. This is on i3wm btw

  Couldn't you just feed a 4k screen a 1080p resolution? It's a bit annoying if it defaults to 4K every time you plug in I guess. If you can use HDMI, you could get an inline EDID adapter.

Fractional scaling in Wayland still needs some work in my experience. Primarily, apps running through XWayland look blurry which sucks because there’s a decent number that font natively support Wayland yet (or have it behind an experimental flag with caveats, like how Anki loses its native titlebar and window shadow when Wayland support is turned on).
