The table can designate a preferred mode or native resolution. The EDID block contains the display's identification, color characteristics (such as gamma value), and table of supported video modes. When a source and display are connected, the source first queries the display's capabilities by reading the monitor EDID block over an I☬ link. It is up to the display to choose which EDID to send. Since the DDC can only support one EDID, this can be a problem if both the digital and analog inputs in the DVI-I port detect activity. If a display supports both analog and digital signals in one DVI-I input, each input method can host a distinct EDID. A newer version of DDC called DDC2 allows the graphics adapter to read the monitor's extended display identification data (EDID). Like modern analog VGA connectors, the DVI connector includes pins for the display data channel (DDC). Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players.ĭVI's digital video transmission format is based on panelLink, a serial format developed by Silicon Image that utilizes a high-speed serial link called transition minimized differential signaling (TMDS).

This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). Featuring support for analog connections, the DVI specification is compatible with the VGA interface. This interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). It was developed with the intention of creating an industry standard for the transfer of digital video content. The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor.
