BenQ claims that their monitors will handle that:

I've got one (MA270S) hooked to a MBP (recommended, if you don't want to spend the dosh on an Apple display), but I haven't yet dug out another Mac to test the KVM. Considering that it's a $900 monitor, like the one in TFA, it damned well better work as advertised.

It's mentioned elsewhere, but check out DeskFlow (oss) https://github.com/deskflow/deskflow

What’s stopping you from running the same command on both Macs? Maybe I missed something.
