Difficulty: HardDisplay Cables and Connectors

An IT technician is auditing display adapter inventories and cable standards for an enterprise workstation hardware refresh. Match each video connector standard on the left with its corresponding signal characteristic or pinout feature on the right.

  • DVI-I Dual-LinkCarries both digital video and analog RGB signals using 4 extra pins surrounding a flat grounding blade.
  • DisplayPort 1.4Natively supports packetized Multi-Stream Transport (MST) data to daisy-chain multiple independent displays.
  • USB-C with DisplayPort Alt ModeRepurposes high-speed lanes on a 24-pin reversible physical interface to transmit native video signaling.
  • HDMI 2.0Utilizes a 19-pin connector layout providing native Audio Return Channel (ARC) and CEC signaling channels.

Answer

DVI-I Dual-Link matches carrying digital and analog RGB signals via additional pins around a flat blade. DisplayPort 1.4 matches native packetized Multi-Stream Transport (MST) for display daisy-chaining. USB-C with DisplayPort Alt Mode matches repurposing high-speed lanes on a 24-pin reversible interface. HDMI 2.0 matches the 19-pin connector layout supporting ARC and CEC.
Each display standard matches its specific physical and functional properties: DVI-I includes 4 distinct analog pins around the flat blade; DisplayPort 1.4 supports MST packetized streaming for display daisy-chaining; USB-C Alt Mode reassigns pins on the 24-pin Type-C interface; HDMI 2.0 operates on a standard 19-pin design with ARC and CEC features.

Step-by-Step Solution

1
Analyze analog versus digital signal pinout configurations on legacy and modern DVI interfaces.
Identify DVI-I Dual-Link as the integrated standard featuring 4 analog pins around the grounding blade.
DVI-I integrates both digital DVI lines and analog RGB lines directly within a single physical connector shell.
2
Evaluate display interface packet structure and daisy-chaining capabilities.
Identify DisplayPort 1.4 as the native provider of Multi-Stream Transport (MST).
DisplayPort utilizes packet-based architecture, allowing multiple independent video streams to travel down a single cable assembly to chained monitors.
3
Examine multiplexed pin assignments across universal serial bus interfaces.
Identify USB-C with DisplayPort Alt Mode as using high-speed lanes on the 24-pin reversible Type-C connector.
DisplayPort Alt Mode reallocates physical differential signal lanes in the USB Type-C cable for direct video transport.
4
Identify consumer audio/video connector standards featuring control and audio return pins.
Identify HDMI 2.0 as the 19-pin standard integrating ARC and CEC signals.
Standard HDMI Type-A connectors use a 19-pin layout with discrete pin assignments for CEC control and ARC audio return.
