Features
Signal Integration: The most prominent feature is that a single interface can simultaneously support digital (TMDS) and analog (RGBHV) signals without the need for additional chip conversion.
High-bandwidth Digital Channels: The dual-link design doubles the digital bandwidth compared to a single-link, enabling higher resolutions and refresh rates.
High-bandwidth Digital Channels: The dual-link design doubles the digital bandwidth compared to a single-link, enabling higher resolutions and refresh rates.
Physical Structure Easy to Identify:
Inside the interface are two rows of a total of 24 pins.
One side has 4 pins surrounding a "cross" or "bar" shaped positioning hole, which is an intuitive indicator distinguishing it from a pure digital interface (DVI-D).
Gradually being replaced: As a mainstream interface of its generation, its functions have been replaced by DisplayPort and HDMI. The latter two support higher resolutions, refresh rates, audio transmission, and smaller interface sizes.
Applications
High-resolution digital display: Connect to a display or projector that supports DVI input to achieve high-resolution display at 1920x1200, 2560x1600 and other 2K levels.
High-resolution digital display: Connect to a display or projector that supports DVI input to achieve high-resolution display at 1920x1200, 2560x1600 and other 2K levels.
Classic graphics cards and motherboard outputs: Widely present on mid-to-high-end discrete graphics cards, workstation graphics cards and motherboard integrated video output interfaces from the early 2010s.
Professional and industrial equipment: Commonly found in professional equipment such as industrial control and medical displays that require stable connections and wide compatibility.
