Granted, I've always had these kinds of issues with new laptops, especially when it came to proprietary nvidia or AMD graphics (before AMDGPU) and I agree it's improved a lot, but I still need to tell people that there's caveats with some (especially newer) laptops.
In 2022.
That is the kind of basic thing that does not work.
In addition to that, if you have a high-DPI laptop display and you want to plug it into a low-DPI desktop monitor (or vice-versa), good luck getting the scaling to work in a usable way.
Sure? This is exactly the thing that Wayland was supposed to solve. Only X has one DPI for all screens.
I still use X because I'm on FreeBSD and I even got multi-screen multi-dpi scaling to work there, with xrandr settings but indeed it was not fun. In Wayland it should be click & play though.
It's not a fault of Wayland but it is reflective of the whole Linux laptop experience.
For example when I move my mouse from my 192 DPI screen to my 96 DPI screen, the mouse position translates in physical pixel, not in physical location. So at the bottom it matches but near the middle of the 192 DPI screen it stops going to the left (it already ends up on the top of the 96 DPI screen going from the middle of the 192 DPI screen) and becomes an 'invisible wall'. Even in Windows 11 they didn't bother to fix this :(
The only OS that had a good transition to multi-DPI capabilities was macOS and that's really because Apple doesn't care about legacy and forces app devs to update their stuff. But it's not just Linux that's having a hard time with this.
But I didn't know this was a specific problem. I'm not using Wayland yet and won't for the foreseeable future. I'm on FreeBSD and KDE on Wayland has been broken a long time. When I hear this it sounds like a good decision anyway :)
