DVI-I is analog with digital. DVI-D is digital only. So any DVI-I card should connect to DVI-D KVM or monitor without an issue.
As for suggestions, I thought I gave these to you in another thread.
I'm using the Starview 4-port DVI KVM.
- The video is perfect.
- Sometimes the shift key sticks (holding it down too long confuses the KVM), and I have to swap to another screen and back again. But it's not too often.
- From what I remember, the audio was pretty terrible, but all KVMs are. I prefer to have dedicated speakers for each system. Less wires = less noise. I've not tried KVM audio in at least 3 years now.
Aside from that, I have no idea.
