Difficulty: MediumDisplay Cables and Connectors

An IT technician is organizing display adapters and cable inventory for a office deployment. Match each display interface standard on the left with its defining technical characteristic or feature on the right.

  • DVI-D Dual-LinkDigital-only video interface supporting resolutions up to 2560x1600 without carrying audio signals
  • VGA (DB-15)Legacy 15-pin analog video interface carrying no digital signals or audio
  • DisplayPort 1.4Packet-based digital interface supporting audio, high bandwidth, and Multi-Stream Transport (MST) daisy-chaining
  • HDMI 2.019-pin digital audio/video interface supporting 4K at 60Hz and Audio Return Channel (ARC)

Answer

DVI-D Dual-Link matches digital-only 2560x1600 video without audio; VGA (DB-15) matches legacy 15-pin analog video without audio; DisplayPort 1.4 matches packet-based digital video/audio with MST daisy-chaining; HDMI 2.0 matches 19-pin 4K at 60Hz with Audio Return Channel (ARC).
Each display standard matches its specific physical pin count, signal type, and feature capability. DVI-D Dual-Link provides digital-only video up to 2560x1600 without audio. VGA is a legacy 15-pin analog-only connector. DisplayPort features packet-based transport allowing MST daisy-chaining. HDMI 2.0 is a 19-pin interface delivering 4K@60Hz with ARC.

Step-by-Step Solution

1
Differentiate signal types (analog vs. digital) and audio transmission capabilities for older display interfaces.
VGA is strictly a 15-pin analog video connection with no audio. DVI-D is digital-only (lacking analog pinouts) and Dual-Link supports higher resolutions like 2560x1600 without carrying audio streams.
DVI-D lacks the four analog pins present on DVI-I, and VGA cannot transmit digital packet or audio data.
2
Analyze distinguishing features of modern audio/video standards (DisplayPort vs. HDMI).
DisplayPort uses packetized data transmission enabling features like Multi-Stream Transport (MST) daisy-chaining. HDMI uses a 19-pin design with consumer features like Audio Return Channel (ARC) and 4K@60Hz support under version 2.0.
MST is an architectural feature specific to DisplayPort, while ARC is an established feature of the HDMI standard.
