Wanted to chime in. Got a 4090 coming, so I'm losing the virtual link usb-c on my 2080 ti. Need displayport because my lg c2 needs to use the single hdmi port. Got an itx setup with only one pcie, so I can't use a passthrough expansion card either...

Tried out both the fairkabe cables (cheap and more expensive one) , and they do not work at all. The reviews had said it worked with the xreal, so I thought it should work with the rokid. Even had the usb power cable connected to a external 5v 1A (exact power requirement for rokid) power adapter, still didn't work. Not gonna een bother trying out the WJESOG one.

Luckily I do have an old dp 1.4 to hdmi 2.0b adapter. Now gotta find the ugreen cm323 or a working alternative.
