Difficulty: EasyDisplay Cables and Connectors

Match each display cable and connector standard on the left with its correct physical characteristic and signal specification on the right.

  • DB-15 (VGA)15-pin connector transmitting legacy analog RGB video signals only
  • DVI-I Single-LinkConnector carrying both digital video signals and analog RGB pins surrounding a flat blade
  • HDMI Type A19-pin connector transmitting digital video, multi-channel audio, and CEC control signals
  • DisplayPort Standard20-pin connector featuring a mechanical locking latch that transmits packetized video data

Answer

DB-15 (VGA) matches 15-pin connector transmitting legacy analog RGB video signals only; DVI-I Single-Link matches Connector carrying both digital video signals and analog RGB pins surrounding a flat blade; HDMI Type A matches 19-pin connector transmitting digital video, multi-channel audio, and CEC control signals; DisplayPort Standard matches 20-pin connector featuring a mechanical locking latch that transmits packetized video data.
Each display standard matches its specific physical pin layout and supported signal type: DB-15 (VGA) uses 15 pins for analog RGB video; DVI-I contains both digital pins and analog pins around the flat blade; HDMI Type A is a 19-pin connector for audio, video, and CEC; DisplayPort uses a 20-pin latched connector to transmit packetized display data.

Step-by-Step Solution

1
Identify the physical properties and signal type of DB-15 (VGA).
VGA uses a DE-15/DB-15 connector with 15 pins and carries pure analog RGB signals.
VGA is an older analog video standard with no digital data or audio transmission capabilities.
2
Determine the pin layout and functionality of DVI-I.
DVI-I (Integrated) supports both digital and analog signals, identifiable by four pins around the flat horizontal blade.
The 'I' in DVI-I stands for Integrated, combining DVI-D digital lines with DVI-A analog lines.
3
Evaluate the pin count and feature set of HDMI Type A.
HDMI Type A uses a 19-pin connector to deliver digital video, audio, and control signals like CEC.
HDMI is the standard 19-pin consumer interface for combined digital video and multi-channel audio.
4
Examine the physical structure and packet transmission of DisplayPort.
DisplayPort utilizes a 20-pin connector with a latching mechanism and packet-based data transport.
DisplayPort is engineered for PC displays using 20 pins and physical latches to secure the connection.
