Ah, interesting - it doesn't work at all on my S20 which was pretty disappointing. I've heard something changed with the update to Android 10 on these.
The DeX client on Windows is interesting, I tried it briefly since I still have one Windows machine lying around. I think overall I still prefer the idea of having my phone be the brains and docking to effectively dumb terminals though, provided there are high-quality docks out there I can use. That's also provided the phone/software is powerful and flexible enough though... DeX isn't that for my personal needs, but some of the upcoming Linux phones/DEs might be.
