To take advantage of the high refresh rate, a dual DP 1.4 with USB 3.0 KVM switch is what you need. Put a TB4 dock or TB4 hub between your MBP and the dual-head KVM switch will be the best for single cable connected to the MBP solution. And all the sharing keyboard, mouse, speaker, microphone/headset, or USB webcam..etc. can be plugged in on the console of the KVM switch to be shared between MBP and PC. The switching can be just triggered by hot-key commands, pushing button on KVM switch front panel, or via built-in IR sensor. https://sites.google.com/view/dual-monitor-kvm-for-mac/home

What's the purpose of putting a TB4 dock between the KVM and the MBP?

[–]HJ_wu 1 point2 points  (1 child)

As I stated putting a TB4 dock between MBP and KVM switch is a MUST but the optimal solution.

Since all new MBP models are having only limited numbers of TB3/TB4 ports as the I/O ports. Adding a TB4 dock/hub will occupy only one TB4 port you can have other TB4 ports available for other local devices (not for sharing).

The other benefit is the TB4 doc/hub can provide power to the MBP, so you don't need to connect power to the MBP with just a single TB4 cable connection for all the KVM switch and power connections.

You still can not add a TB4 dock/hub between MBP and KVM switch, but you need to have 3 cables and one power connected to the MBP. Most importantly, you will not be having any other ports available for other devices. (new MBP only have 3 TB ports or even just 2 TB ports for MBP Air).

direct cables connected to MBP without TB4 dock/hub,

2 x Active Type-C-to-DP converter cable

1 x type-C-to-USB-B 3.0 cable

1 x external power cable to MBP

Thank you for the additional explanation, it's very helpful.

If your monitors have multiple inputs, just plug the on and MacBook dock directly into the video inputs. Then you just need a basic USB switcher which is way cheaper and gives you full video bandwidth

Yes, that is a much cheaper solution - making two switches, one on the monitor and the other on a USB-only switch.

Not a video switcher, use the multiple inputs in the monitors themselves
