I upgraded my gaming rig's monitors 3 weeks ago, and I'm using the old ones in my home office: 2x 24" 1920x1200 monitors in portrait. The old office monitors had cheap stands and didn't rotate. I can't say that it's a no-brainer upgrade, but I'm OK with it.

Did you find any solutions for tiling windows vertically?

Windows 10 definantly does not do this well.

FancyZones (part of Microsoft PowerToys) works well for me. I also like the fact that it's first-party, free and open-source:

FancyZones docs: https://docs.microsoft.com/en-gb/windows/powertoys/fancyzone...

I just downloaded it..

Why does Microsoft not promote this more?

I may not need to use Linux now for a while

On macOS I use hammerspoon to define window positioning keyboard shortcuts. With my 4k monitor I can place windows in a 4x2 grid, or 4 columns (both similar layouts to my two-screen setup), or 3 columns, or left half / right half / middle half (with two narrow columns either side).

On Linux I use i3wm, but I have not yet configured it for my 4k setup.

I use Divvy[1]. It also works on MacOS. I use gTile on Linux. The combination lets me use the same keyboard short cuts (or close enough) on all 3 OSes.
