How many 4ks at 120hz can it run? Asking for a friend
It should support at least 3. In case you’re seriously asking, TB3 is 40GBps and supports 1 display at 4k@120 with DP 1.4.
4K UHD needs a bandwidth of at least 10.2 Gbps, so this could drive eleven 4K displays
It can be much higher - depends on how much color information you’re sending, and what the refresh rate is.
The DisplayPort spec (which alt mode runs across usbc) covers the streams:

So some number from 3 to 11 apparently.
3x 4K at 144hz, it’s right in the graphic in the article.
