These adapters also need to have their Mac drivers installed and, as luck would have it, they already work on macOS Big Sur. Tulupov, fortunately, shares the secret to his magic tricks, which pretty much involves using DisplayLink adapters to connect HDMI monitors via the Macs’ USB-C ports. Again, the total still depends on the screen resolutions being used. The M1 Mac mini can have as many as 6 monitors attached to it while the M1 MacBook Air and M1 MacBook Pro could connect 5 external displays (also for a total of six, counting the built-in screen). YouTuber Ruslan Tulupov, however, discovered that the M1 Macs can support more than Apple’s advertised combinations. The M1 Mac mini, in contrast, can connect only one 6K monitor and one 4K screen via two different ports. The Intel Mac mini, for example, can combine either three 4K monitors or one 5K and one 4K monitors.
As always, the number of displays you can connect to these Macs isn’t straightforward and depends on the resolution of the monitors being connected.
