This is quite infuriating...seeing as it is definitely not a hardware limitation. Is there some way we could get them to do something about this? It seems to be an ongoing issue (10 years +) and no one does anything about it. I do not understand how such an issue has not been addressed yet.
MacBook Pro 14″, macOS 13.1
DisplayPort version 1.2 was introduced on 7 January 2010.[11] The most significant improvement of this version is the doubling of the data rate to 17.28 Gbit/s in High Bit Rate 2 (HBR2) mode, which allows increased resolutions, higher refresh rates, and greater color depth, such as 3840 × 2160 at 60 Hz 10 bpc RGB.

That says a 4K Hi-color display essentially saturates a USB-C cable's 20 G bits sec capacity.
There is nowhere else for additional data for an additional display to go.
The Mac supports up to two displays on one cable only when that cable is a genuine Thunderbolt cable appropriately rated for high speed 40 G bits/sec and appropriately short, 0.8 meters or less, and connected to a genuine Thunderbolt device (Dock or Display) as the first device.
In my opinion, USB-C cables do not have enough bandwidth to be generally useful for his purpose.

Why does Apple STILL not support DisplayPort MST?
