That doesn't "Just work" on Windows 7 or 10, though, so not sure it's a failure on the part of Linux as much as a success on the part of macOS.

Anecdata incoming, multi-monitor on Win 10 works just fine for me. I've got 2 screens attached to my laptop and they're just fine, even with different scaling on each one.

It does work though. X can't be configured with 2 different DPIs at all.

  Are you sure? http://wok.oblomov.eu/tecnologia/mixed-dpi-x11/ http://wok.oblomov.eu/tecnologia/mixed-dpi-x11/ I can't say I've played around with it, but the above seems to indicate that such support is available - but that you might have issues with apps not supporting it (or reporting their DPI properly). There also might be problems with other layers above raw X (?) - but it seems like X itself does support it in some manner? I once had X supporting two mice on dual monitors (this was a while back - I had a couple of CRT monitors at the time); seeing that made me think X could do almost anything I asked of it (depending on how I "asked").

    Nope! Looks like I was wrong. I was never able to get it working on Gnome without the upscale/downscale workaround suggested in your link (resulting in terribly degraded image quality), but perhaps that is the fault of Gnome/GTK. It wouldn't have occurred to me that the fault could lie in any other layer than that which controls the resolution/DPI, but I'm certainly no expert on the Linux graphical stack.

How does that fail? I've never had issues with multi-monitor, and they've always been 3 different resolutions (with one rotated 90). I'm not doubting you, as my current win10 install won't let me change the default JSON association away from visual studio and I can't find anyone else with that problem. I'm just curious what fails, since I haven't encountered problems with multi-monitor since XP.

  I hate running multiple monitors in Windows 10. I was running 24" + 27" BenQ monitors (same model/specs, just diff sizes) and Windows would reboot and ignore both. On my laptop I would go into the display settings and try to turn them on and just get a "Failed to save settings" message. This usually resolved itself after a reboot or two. I honestly got so tired of it I just invested in an Alienware 34" monitor. I haven't had the problem since.

    I should add that while Ubuntu did not have this problem.. because the monitor configuration is apparently loaded post login screen I had other issues - like my login prompt being on the wrong monitor. Especially if I was using LUKS on my primary drive, but that one is a bit more obvious as to why. *setup is an Alienware 15 laptop which supports dual monitor out for up to 3 active displays if including the laptop monitor

I can boot my system into windows 10 right now and it all just works.

Since there are counter-anecdotes, I'll throw in my supporting anecdote: I've had endless problems with multi-monitor on Windows 10. Especially if they're different display densities. Windows that go out of bounds and are un-retrievable, permanently glitched window-content rendering when moving between densities, inaccurate mouse positions, desktops that resize to like 320x200 and then to the actual (shrinking every window and mashing all icons together, and breaking the notification area and status bar area in the process), I don't think I've ever had it work out-of-the-box even once on multiple machines and multiple monitors / projectors / etc. Some of this only occurs the first time it learns a new setup, but much of it just keeps happening randomly. On macs for like the past 5+ years? Almost perfect behavior, for almost every OS version, except on apps that clearly do their own thing (e.g. IntelliJ sometimes shrinks to nothingness, and Steam is just hot garbage much of the time).
