Hey Folks, I've been using the Belkin VR cable for awhile now. No problems really but it is a long cable, and I've had to be really careful with signal integrity through the KVM switch and to the other computers. I stumbled on a new cable on Amazon and decided to test it out. Good news: works great, it's cheap, and ships fast. I'm running stable at 6k with full brightness/etc controls via USB.
The cable made by "WJESOG" is
on Amazon here for US$30. Make sure you get the "DP to USB-C" version.
If folks are hunting for a decent KVM switch, I've moved from my older StarTech DP1.2 2-port to the
Monoprice Blackbird (also on Amazon for US$140 as of this writing) DP1.4 4-port. The video signal has been solid so far, but the USB HID emulation leaves a lot to be desired ... ended up with the keyboard and mouse on the non-HID ports to make everything work properly. Nothing is perfect in the KVM switch market, but it's good enough for now.
This is on a 2019 Mac Pro, AMD Radeon Pro W5700X GPU.
