Difficulty: MediumDisplay Cables and Connectors

Match each display cable or connector standard on the left with its defining physical or operational characteristic on the right.

  • DVI-D Dual-Link24-pin digital-only interface supporting resolutions up to 2560x1600 without analog pins.
  • VGA (DB-15)High-density 15-pin connector carrying purely analog RGB signals.
  • DisplayPortVESA royalty-free standard utilizing packet-based data transmission and optional latching pins.
  • HDMIProprietary digital video and audio interface featuring Audio Return Channel (ARC) capabilities.

Answer

DVI-D Dual-Link matches the 24-pin digital-only interface supporting resolutions up to 2560x1600. VGA (DB-15) matches the high-density 15-pin connector carrying purely analog RGB signals. DisplayPort matches the VESA royalty-free standard utilizing packet-based data transmission and optional latching pins. HDMI matches the proprietary digital video and audio interface featuring Audio Return Channel (ARC) capabilities.
Each display technology possesses distinct physical and signal characteristics: DVI-D Dual-Link provides digital-only video at high bandwidth via 24 pins; VGA (DB-15) is a legacy 15-pin analog RGB connection; DisplayPort is an open VESA packetized video standard with latching connectors; and HDMI is a consumer AV standard supporting integrated audio technologies like ARC.

Step-by-Step Solution

1
Identify signal type and pin configuration for analog legacy interfaces.
VGA (DB-15) is identified as the 15-pin analog-only connector carrying RGB video.
VGA is the only purely analog display connector in the list.
2
Differentiate DVI variants based on signal capability and bandwidth.
DVI-D Dual-Link is identified as the 24-pin digital-only high bandwidth interface.
The '-D' suffix indicates digital-only, and Dual-Link provides the extra pins needed for 2560x1600 resolution.
3
Distinguish modern digital interfaces by architecture and proprietary features.
DisplayPort pairs with packet-based VESA standard featuring latching connectors, while HDMI pairs with consumer AV features like ARC.
DisplayPort relies on packet transmission (micro-packets) while HDMI includes consumer electronics features such as ARC and CEC.

Key Concept

Display standards vary by signal format (analog vs digital), pin count, packet architecture, and feature sets such as ARC or physical latching mechanisms.
