One of these?
Looks like it has a micro HDMI port.
So one of these should work:

Buuut... it's HDMI 2.0, not 2.1. So you're going to be limited to 4K/60.
4K/120 won't work on 2.0.
They do make HDMI to USB-C cables, but you have to plug in to both the HDMI AND a USB port on the PS5 to power the output to the USB-C monitor.

Also more expensive.
And then this is the actual cable I bought.
Could they both be wrong? I have tried both.
