What changes the connection decision?
For two independent native desktops, this host limit is the first constraint. An ordinary Thunderbolt dock or MST hub cannot remove it. A DisplayLink device uses a software display path and has separate OS, permission and protected-content limitations.
On macOS, two sockets on an MST hub can mirror rather than extend. Count independently supported display streams, not physical HDMI or DisplayPort sockets.
Manufacturer evidence
These are documentation findings, not NYBreaking hardware tests. A successful source fetch checks availability; it does not independently prove every connection.
