Difficulty: MediumDisplay Cables and Connectors

An IT technician is configuring a desktop workstation to drive three independent external monitors using a single output port on the graphics card. The deployment plan specifies daisy-chaining the monitors sequentially from one screen to the next. Which display interface standard natively supports this Multi-Stream Transport (MST) configuration?

  1. DisplayPortAnswer
  2. B
    HDMI
  3. C
    Standard USB 2.0 Type-C
  4. D
    Dual-Link DVI-D

Answer

DisplayPort is the correct display interface standard, as it natively supports Multi-Stream Transport (MST) for daisy-chaining multiple independent displays from a single port.
DisplayPort (v1.2 and later) introduces Multi-Stream Transport (MST), allowing a host computer to transmit multiple discrete video streams across a single DisplayPort interface. Compatible monitors with a DisplayPort Out port can pass subsequent streams down the chain to additional monitors.

Step-by-Step Solution

1
Identify the key requirement in the scenario.
The scenario calls for connecting multiple independent monitors to a single port using a daisy-chain setup.
Understanding display transport features is necessary to select the correct cable interface standard.
2
Evaluate candidate display standards against Multi-Stream Transport (MST) capabilities.
DisplayPort 1.2 and newer standards support MST, allowing a graphics card to send distinct display streams through a single DisplayPort output to monitors equipped with DisplayPort Out ports.
Legacy formats (DVI, VGA) and standard HDMI do not support native display daisy-chaining.
