Do you know what sucks? DisplayLink. It's 2023, and the best we have for 3 monitors (MacBook Pro, and 2 external monitors) is basic screen scraping with software drivers if you want to use a single cable... otherwise you have to fall back to 2 cables (one for power + first monitor, and one HDMI).

The other reason why DisplayLink sucks is performance (or lack of) - what they don't tell you on the box. Video is like 16FPS on my third monitor!

This is only because MacBooks do not support MST. On all of my non MacBook laptops I can use multiple monitors over USB-C.

Macbooks (at least the intel ones) support MST with another OS like Linux.

The missing support is in MacOS.

Ah damn. After your comment and reading around here, looks like it's going to be impossible to support this natively with a single cable.

... there goes my cable feng shui

If you have high end monitors (4K 120Hz or 6K 60Hz), each monitor will use up all the bandwidth so using one cable for multiple monitors is a nonstarter.

IIRC there's a way around this limitation with DSC and thunderbolt docks, but it's not worth the effort.
