Four-screen ceiling requires the internal panel disabled in Windows; merely closing the lid is not sufficient evidence. Exact dock, bandwidth and cables remain unreviewed.
What changes the connection decision?
A host ceiling of 3 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.
For Windows, inspect the exact graphics configuration and whether the built-in panel is enabled. Dock bandwidth and cable capability can reduce the modes available across several screens.
Manufacturer evidence
These are documentation findings, not NYBreaking hardware tests. A successful source fetch checks availability; it does not independently prove every connection.
