I think Dell has pretty good support for this, I had a pretty old Dell model before my current monitor and ddc worked fine with it. I now have an AORUS FO48U and it also supports it. I'm not sure it's always listed as a feature though when you're buying a monitor so it might be tricky. FYI, I originally learned about this stuff via https://haim.dev/posts/2020-07-28-dual-monitor-kvm/ https://haim.dev/posts/2020-07-28-dual-monitor-kvm/.
