DP > DVI Cable is below. It looks to be passive alright: amazon.co.uk/gp/product/B07FZLGN6S/… Thanks for help. I will buy an active DP>DVI adapter and see if it works and post back

So I bought an active DP>DVI adapter and its still not working. The adapter is DP male to DVI female. And I then have a standard DVI male to male cable connection between the adapter and monitor. Do I need a specific DVI cable here?

I don't think so. It's just that because of the kvm in between / the source not being DP from the start, I wonder if you need an adapter that takes dedicated external power from a USB port or whatever.

Either way it's still just all theory from me, so don't have too much expectation that it could actually work with such double conversion chain.

KVM reads EDID and knows 2 DVI monitors are attached. The KVM firmware is programmed to know that some graphics cards support dual mode (DP++) and send HDMI signal through the DP++ port when HDMI monitors are detected. Hence, DP++ -> KVM -> DVI works because KVM passes through incoming HDMI signal to DVI monitor. Exotic case involving a DP->DVI converter is apparently not considered by Depzol KVM. So it probably just blocks the incoming DP signal when a DVI/HDMI monitor is attached as it has no means of knowing that there is a a DP->DVI active converter between it and the DVI monitor.
