I'd like to buy a new monitor and have been looking at models that have an in-built **KVM** switch functionality as this would both reduce cabling/connections and enable me to use the monitor for home and Work-From-Home easily. I'm aware [I could get a separate KVM](https://apple.stackexchange.com/questions/384476/usb-c-hdmi-switch-for-macbook-pro-mac-mini), but one that's already in the monitor seems ideal.

I have a home [MacMini (2020, M1)](https://support.apple.com/kb/SP823?locale=en_US) and a work [MacBook Pro (16" late 2019, Intel)](https://support.apple.com/kb/SP809?viewlocale=en_US&locale=en_US). Both have USB-C connectors with [Thunderbolt 3](https://en.wikipedia.org/wiki/Thunderbolt_(interface)#Thunderbolt_3) which both state:

> 
> Native DisplayPort output over USB‑C
> 
> 
> 

in the technical specs (linked above).

I'm aware that I may need specific cables such as [Apple Thunderbolt 3 (USB-C) Cable](https://support.apple.com/en-gb/HT208368)

*Before buying the monitor*, is there any way to verify that at least one of the Macs has the required feature/signalling to communicate to the monitor so that it can use the KVM feature?

This whole question was brought up by a [review of the monitor](https://www.rtings.com/monitor/reviews/gigabyte/m32u#page-video) which mentioned the DisplayPort Alt Mode issue.
