I have a Dell U2720Q monitor that accepts HDMI 2.0, DisplayPort 1.4 and USB-C. I use USB-C because the monitor acts as a hub for a range of peripherals (keyboard, mouse, webcam, speakers, etc.etc ...

If you have the opposite type of cable, or a CTIA/OMTP adapter, you could give it a try. Also, the manual shows the socket as AV OUT / PHONES so a 3.5mm to 2 RCA cable should work.

All told, the selling point of both the Ultra96 cable and HDMI 2.2 specification are the increased bandwidth, which doubles the HDMI 2.1 bandwidth from 48Gbps to a staggering 96Gbps.
