Hi, I was wondering about the software utilised in DIY KVM products like PiKVM and BliKVM.

If I understand correctly, to be able to interface with a computer like with a KVM, you would have to:

1. Have an HDMI capture card capture the feed from the server.
2. Feed it into the main computer.
3. Have both a VNC server and VNC client running on the main computer.
4. Feed the HDMI capture to the VNC server.

If this is indeed the flow, then why do people use PiKVM? Or if I’m missing a step/am wrong in these steps, please let me know.

Thanks!
