Display count is the host ceiling, not a promise for every dock or resolution.
What changes the connection decision?
A host ceiling of 2 screens does not mean every dock exposes that many independent outputs. Check the selected mode and whether the dock uses Thunderbolt display streams, MST or DisplayLink.
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.
