Does it now support using two monitors with different scaling factors? With display calibration?

This is what is holding me back at the moment: heterogenous scaling is only available in wayland, but color calibration (colord-kde) only works in X11.

I think I'll give Gnome another try this time around.

I had the same issue with my 14,0" WQHD (2560x1440) laptop screen and my external monitor. I wanted to scale up only the laptop's screen so that I can read the text on it, but then my external monitor got scaled too large.

After using it for months like that I solved this by simply setting the resolution on the laptop to 1920x1080, and scaling to 1. I felt really stupid after that I did not do this sooner.

That's not an optimal solution though, because you're relying on your screen to do non-integer scaling and you'll have blurrier fonts etc. as a result.

If your software supports non-integer scaling it can render things with that knowledge and give you crisp edges on the edge of text and UI elements.

Sadly color calibration is not yet available in KWin-wayland. I saw a MR around but it didn't got merged yet. It will probably come in Plasma 5.21.
