Best 4-Monitor DP 1.4 KVM?

I have 4 Dell U2722Ds, and I’m driving them on a 3070 Ti which has 3 DisplayPort ports using just 2 in a 2x2 daisy-chain – I was looking into a KVM that could swap that entire setup between a different machine.

This one looks like all I need, but it specifically warns about dell monitors, and I’m not 100% if it means the 2x2 configuration I’m going for would work:
[store]14-kvm-switch-dual-monitor-2computer-z5erd-n6mbj

I would love to go for this one, even though I don’t have a use for the last DP port, but if I couldn’t chain at least one of them then I wouldn’t be able to drive it with my graphics card anyway:
[store]14-kvm-switch-quad-monitor-2computer-t6dr4-6cwaa

2560x1440 @ 60 is really the top of what I’m going for, and all the other products that allege to handle 4 DP say in the fine print that they do each monitor at 1080 at best, and make no mention of EDID.

Thoughts?

Daisy chain works fine via the kvm but Macs don’t do daisy chain. And some dell monitors are buggy with daisy chain

Those specific ones are maybe okay assuming your other input device supports mst/daisy chain and isn’t a Mac
