Video Connectors Overview
This section provides an overview of various video connectors, including VGA, HDMI, DisplayPort, and DVI.
VGA Connector
- The VGA connector is a DB-15 connector commonly known for its blue color associated with the Video Graphics Array.
- It does not integrate audio signals within the video connection, requiring a separate audio connection.
- VGA signal degradation occurs beyond 5 to 10 meters due to its analog nature.
HDMI Connector
- HDMI is a digital connection that combines video and audio signals in one cable.
- HDMI cables can extend up to around 20 meters without significant signal degradation.
- The common type A connector for HDMI is proprietary and specific to HDMI interfaces.
DisplayPort Interface
- DisplayPort is a digital standard capable of transmitting packetized video and audio signals.
- It features standard and mini DisplayPort interfaces, with locking mechanisms for secure connections.
- DisplayPort is passively compatible with HDMI through appropriate cables.
Video Adapter Interfaces
This section explores video adapter interfaces such as HDMI, DisplayPort, and DVI in detail.
Video Adapter Outputs
- Video adapters may support multiple outputs like HDMI, DisplayPort, and DVI interfaces simultaneously.
- These interfaces allow connecting to various display devices efficiently for enhanced user experience.
DVI Interfaces
- Digital Visual Interface (DVI) supports single link and dual link connections for different throughput capacities.
