HDMI or DisplayPort cable — which should a project specify?
Choose by device ecosystem and topology, not by which one is "better".
Answer: choose by what the devices actually are and how many screens you need — the two standards are not ranked, they are aimed at different ecosystems.
Scenario
Usually
TV, projector, AV receiver, set-top box
HDMI
PC monitor, multi-display, daisy chain
DisplayPort
Long run to a display
Either, via AOC/fibre
Laptop docking to one 4K screen
USB-C DP Alt Mode
A converter at either end adds a failure point and is capped by the weaker side — specify the native standard where possible.
