I think I’m a unicorn. 14” M1 Max, triple displays, albeit with two cables. We also have an M1 Pro in the house w/ CalDigit TS3 (non-plus), which is driving dual 4k’s without issue.

I’m confused why the author didn’t just purchase one of the cornucopia of Thunderbolt 3 (or 4) docks that do everything including display output.

Triple config (M1 Max): - OWC Thunderbolt 4 dock, connected to 2 4k displays, network, speakers, USB devices - 5k display connected direct to the mac

Dual Config (M1 Pro): - CalDigit TS3 dock, connected to 2 4k displays, speakers, ethernet, USB devices

Works perfectly, and we have no complaints about either config.

Why Is the 5k direct connect? Because there aren’t any TB docks that support 3x displays when pushing > 4k; I’m unclear if it’s technically possible.

I had previously run triple displays on a 13” Intel MBP using an eGPU. I wrote about that journey here: https://www.codevoid.net/ruminations/2020/09/27/three-displa...
