On: The Peculiarly Quiet Decline and Fall of the KVM

I think the real isssue is with HDCP.

The output device "ensures" the display device is authorized via a key to output.

So, you would need an intermediary device that would accept any incoming signal, while also having a legit handshake with the output device.

So, as you switch "inputs", there is no additional authorization required, because the output device does not detect any changes.

It's absolutely not HDCP since a 4k HDMI splitter is much cheaper than a 4k KVM.

My guess is that with KVMs disappearing from server racks, there isn't enough volume to get the prices we used to get.

I believe this is also the case. The only organizations that can get exemptions from the HDCP Alliance (DRM Cabal) for devices that effectively circumvent encryption are for high end broadcast gear. Nothing precludes making a 4k KVM. Infact, a mid range AV main unit could probably route 4k KVM.
