An IT technician is configuring a dual-monitor workstation using a laptop equipped with a single USB Type-C port that supports DisplayPort Alternate Mode (DP Alt Mode), but lacks Thunderbolt certification. The technician intends to connect two 1080p external displays by daisy-chaining them using DisplayPort Multi-Stream Transport (MST). Which of the following requirements or features are necessary to successfully support this configuration? (Select TWO.)
- The primary monitor in the chain must feature a DisplayPort Output (DP-Out) port that supports Multi-Stream Transport.Answer
- The USB Type-C cable connecting the laptop to the primary display must explicitly support DisplayPort Alternate Mode video transmission.Answer
- CAn active Thunderbolt 4 host controller must be present on both monitors to negotiate multi-stream video routing over USB Type-C.
- DA single-link DVI-D cable must connect the primary and secondary monitors to transmit the required analog timing signals.
Answer
The setup requires a USB Type-C connection supporting DisplayPort Alternate Mode from the laptop, and a primary monitor equipped with a DisplayPort Output (DP-Out) port that supports Multi-Stream Transport (MST).
DisplayPort Multi-Stream Transport (MST) enables daisy-chaining multiple monitors over a single video output. For this setup to function from a non-Thunderbolt USB-C laptop port, the host cable and port must support DisplayPort Alternate Mode to output the initial video data, and the first monitor must have an integrated DisplayPort Output (DP-Out) port supporting MST to pass the second display stream down the chain.
