You can check out a detailed walkthrough of the setup in the videos below. The workaround isn’t too complicated and involves downloading the DisplayLink software for macOS (Tulupov says works fine with Big Sur) and picking up a 4K DisplayPort to USB 3.0 adapter (and/or HDMI adapter).ĭepending on how many displays you want to run with this trick, you might need a USB-C to USB-A 3.0 adapter or a Thunderbolt or USB-C dock as well as additional cables, etc. YouTuber Ruslan Tulupov has shared two videos demonstrating the workaround he discovered (via MacRumors). However, just like we’ve seen in the past when Mac compatibility with Apple’s Pro Display XDR was found to be broader than Apple says, it appears that M1 Macs can indeed run up to 6 external displays with good performance… at least in early testing.

And the Mac mini up to 1 6K at 60Hz over USB-C/Thunerbolt and 1 display up to 4K at 60Hz over HDMI. In what looks like some exciting news, it appears Apple may be underselling the M1 Mac external display functionality.Īpple says in its tech specs the M1 MacBook Air and 13-inch MacBook only support up to 1 external display up to 6K at 60Hz.

While almost all aspects of M1 Mac performance are greatly improved compared to the Intel Mac predecessors, one notable downside has been reduced support for external displays.
