Apple

I am a diehard Apple fanboy and don’t see any viable alternative for any of their main product lines. But their multi monitor performance is comically bad: I have Thunderbolt docks and two monitors work fine through that from a technical perspective. Though dragging windows between monitors is not seamless and macOS even rubs it in your face with some quirky UI hints when you are “leaving” one monitor and enter another like it’s the 90s. Icons and real life data in the menu bar have had scaling issues for a decade now on the screen you are not currently active on with a window (but can still see in real life, because eyes). There is an old desktop wallpaper saved somewhere from when I first connected the monitors that stays on the second one (the first monitor has my normal wallpaper). I know I can change this independently, but why?! When opening monitor settings you can adjust things like refresh rate or color profile independently, which is nice, but each window for adjustments opens on the screen it is adjusting. Apple’s whole multi monitor experience feels clunky and dated and hasn’t been getting any improvements for years, which tells me, nobody at Apple uses multiple screens.

You are saying absolute shit

M1 supports one external 4K display on laptop, two on the mini

M1 Pro supports 2 external 6K displays on laptop, 3 on the mini

You can extend any M1 Capability with an external hub.

Furthermore, you are comparing Linux (an Operating System) to the M1 (hardware). That’s stupid.

Not ideal but the volume control can be fixed using monitor control: https://github.com/MonitorControl/MonitorControl

And there are many third party implementations of snapping like magnets.
