How is the multi monitor story? Especially when the resolutions or refresh rates do not match?

If you have mixed resolution, mix refresh rate, and mixed DPI setups, anything Wayland native will be just fine. XWayland can still have some quirks, but I'm not sure if that's an easily solvable problem (or at all). Though I don't have HiDPI displays, I have a triple monitor setup with NVIDIA (2x 1920x1200@75Hz~96ppi and 1x 2560x1440@60Hz~108ppi) and though I use Xorg due to some specific applications, the Wayland session is completely usable and fine otherwise for 99% of my use cases. I actually wish I could use it full time. This is on Fedora 36 Workstation.

  By "have some quirks" you mean windows will either show as 200% or 50% size on one monitor which is usually unusable. But you're right, its not anything the Wayland side can control, but as a user, you are better off just getting your monitors to have the same DPI than to wait for every single electron app to update it's base electron version.

I have a 5k monitor and a 4K laptop screen that I run simultaneously. It all works seamlessly in my experience (Fedora 36, vanilla Gnome).

I have two 1920x1080 60fps screens and one 2560x1440 120fps screen and they work perfectly in sway. The DPI between them is different but it's minor enough that I haven't bothered fixing it

Better than X but still not perfect. If you have neat monitors where the difference in pixel dpi is simply an integer multiple (1×, 2×, etc) it's really good, no issues at all. If you need fractional diff in pixel dpi (e.g. you want one screen at 1× and the other at 1.5×) it can kind of work, but dodgy - the 1.5× screen will have its windows rendered at 2× then downscaled, so won't be pixel crisp (and the unnecessary 2× render can push limits on old integrated graphics cards) If you need diff in text dpi, e.g. like setting Xrdb.dpi or gnome's Scaling Factor, then you're up shit creek (but with X11 to keep you company)
