This seems laptop specific, i.e. having the MacBook + 2x external extended displays via Thunderbolt. I think surely the Mac Mini M1 works with 2x monitors though (extended)? Has anyone tested this?

The Mac mini M1 can drive two independent screens - one over HDMI, one over USB C. The limitation seems to be number of screen outputs, and a laptop has one already built in, hence only 1 external.

That is what I'm planning to do. Mac Mini with two 4K screens running at 60Hz. Was just making sure that it would work.

I've been running this setup. Mac mini M1 connecting to LG 4K monitor over HDMI at 60 Hz, with DisplayPort to a 4K Wacom Cintiq also at 60 Hz. It works flawlessly.

Out of interest's sake, what kind of resolution are you running? I found 3008x1692 to be perfect for my 4K screen, but it actually doesn't show up in Display preferences unless you option-click the "Scaled" radio button.

I'm using the standard scaled 1920x1080 resolution on both of my screens. I don't see the 3008x1692 option on my 27-inch LG 4K, but I do see the option on 16-inch Wacom Cintiq. It's a little bit too small on my 16-inch, though.

I see. On my screen, 1920x1080 would be far too large, but then the full blown 3840x2160 resolution would be absolutely tiny. I tried to approximate something that is similar to my MacBook Pro's retina screen. I guess it also comes down to what one is comfortable with. The beauty of the 4K screens is that no matter the resolution, the text is always crisp.

I sit about 45 cm away. Quite comfortable. Loving the Dell 4K.

Ah. I sit about 60~80cm away most of the time from my bigger 4K screen (due to the space needed for my Cintiq when I'm drawing). I tried several resolution after your previous comment and found 2048x1152 to have the best balance between real estate and readability at my viewing distance. I should give this a try for few days. Thank you for suggesting to have a look at the resolution!

I have been using an M1 setup with three screens for the last month. For the first two monitors, I use one usb-c port and one hdmi. For the third monitor, i use a Startech usb-a to htmi adapter using display-link. It works.
