That's interesting. When you go to the KVM wizard on the monitors menu what does it show is tied to Displayport/HDMI? It should be USB-B and your laptop should be Type-C:Type-C
Not sure if you can help, I've been researching this monitor as a potential purchase - and google led me to this forum.
I run two PCs with one monitor currently using an external keyboard and mouse switch. If I got this monitor would like to use the inbuild KVM but don't want to use the USB-C as the video input.
Ideally DP for one video input, and HDMI for the other. The USB-B output appears as though it can be assigned to either HDMI or DP, just wondering if you know if the USB-C can be used as just an output for the Keyboard and Mouse and not for display?
My hope is that I can do HDMI with USB-B for one PC & DP with USB-C with the other.
Thanks.
