One Desktop, Four Clients Without Any Thin Client?

Question

The videos below appear to have connected all monitors in to a single desktop without any thin clients in between. It looks like he installed 4 video cards in the desktop. It also looks like they have their own separate audio as if there was a client in between but there's none.

The place appears to be a low-end internet cafe but it looks like he's saving a lot of energy in this setup. Any ideas how did he achieve this?

Answer 1

I believe he is using this software:

Basically, what you mention (different video cards) and audio for each one comes from USB ports.
