A DVI (Digital Visual Interface) port transmits digital video signals from a computer to a display, offering high-quality, uncompressed visuals. Developed by the Digital Display Working Group (DDWG) in 1999, DVI supports multiple signal types (DVI-D for digital only, DVI-A for analog, and DVI-I for both) and comes in single-link and dual-link configurations for different resolutions and refresh rates, with dual-link supporting higher resolutions like 2560x1600 at 60Hz. Unlike HDMI, DVI does not support audio transmission, but it can be converted to HDMI using an adapter cable to send both audio and video signals to other devices.

Key Features

Digital Video Transmission: DVI focuses on sending high-quality, uncompressed digital video signals, resulting in crisp and clear images.

Signal Support: DVI ports can be digital-only (DVI-D), analog-only (DVI-A), or support both digital and analog signals (DVI-I).

Single-Link vs. Dual-Link: Dual-link DVI provides more conductors and bandwidth for higher resolutions (e.g., up to 2560x1600 at 60Hz) compared to single-link.

Audio Incompatibility: DVI does not support audio transmission; the signal is strictly for video.

Compatibility: DVI ports are designed to connect to digital flat-panel monitors and projectors, and DVI-I can be compatible with analog signals from a VGA port.
