Difficulty: MediumDisplay Cables and Connectors

An IT support specialist is inventorying video cables and display adapter types across workstations in a corporate environment. Match each display connector standard on the left with its correct defining signal and functional characteristic on the right.

  • DB-15 (VGA)Legacy connector utilizing 15 pins across three rows to transport exclusively analog video signals without integrated audio.
  • DVI-D Dual-LinkDigital-only connector incorporating additional pins in the center matrix to double data bandwidth for high-resolution displays.
  • DVI-I Single-LinkIntegrated connector providing both digital video pins and four dedicated analog pins, enabling passive DVI-to-VGA adapter usage.
  • DisplayPortPacket-based display interface developed by VESA that natively supports Multi-Stream Transport (MST) daisy-chaining.

Answer

DB-15 (VGA) matches the 15-pin legacy analog video description. DVI-D Dual-Link matches the digital-only connector with extra pins for double bandwidth. DVI-I Single-Link matches the integrated digital/analog connector with pins for passive VGA conversion. DisplayPort matches the VESA packet-based standard supporting MST daisy-chaining.
Each connector standard is uniquely paired based on signal transmission mode (analog vs. digital), pin layout, and supported architectural capabilities like MST daisy-chaining and dual-link bandwidth scaling.

Step-by-Step Solution

1
Identify physical and signal capabilities of VGA (DB-15).
VGA uses a 15-pin connector arranged in three rows and transfers analog-only video.
VGA has no digital capability and carries no audio signal.
2
Differentiate DVI-D from DVI-I and Single-Link from Dual-Link.
DVI-D is digital-only. Dual-Link expands pin connections to double bandwidth. DVI-I includes 4 analog pins around the flat grounding blade, allowing a simple passive adapter to extract analog RGB for VGA.
DVI-D lacks the four analog pin holes around the flat blade present in DVI-I.
3
Identify VESA packet-based video standards and features.
DisplayPort sends data in packets (similar to Ethernet) and supports Multi-Stream Transport (MST) to connect multiple displays via a single DP output port.
MST daisy-chaining is a native feature of DisplayPort specifications.

Key Concept
