For longer distances, the use of a DVI booster is recommended to mitigate signal degradation. Cable lengths up to 15 m (50 ft) can be used with displays at resolutions up to 1,280 × 1,024. This resolution will work even up to 10 m (33 ft) if a special cable is used. In general, cable lengths up to 4.5 m (15 ft) will work for displays at resolutions of 1,920 × 1,200. The maximum length of DVI cables is not included in the specification since it is dependent on bandwidth requirements (the resolution of the image being transmitted). If both receivers are active, analog EDID is used. If a display supports both analog and digital signals in one input, each input can host a distinct EDID. DDC2 (a newer version of DDC) 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). The data pairs carry binary data at ten times the pixel clock reference frequency, for a maximum data rate of 1.65 Gbit/s × 3 data pairs for a single DVI link. The second link can also be used when more than 24 bits per pixel is required, in which case it carries the least significant bits. When both links are in use, the pixel rate on each may exceed 165 MHz. The DVI specification mandates a fixed single link maximum pixel clock frequency of 165 MHz, where all display modes that require less than this must use single link mode, and all those that require more must switch to dual link mode. When more bandwidth is required than is possible with a single link, the second link is enabled, and alternate pixels may be transmitted on each, allowing resolutions up to 4 megapixels at 60 Hz. ![]() ![]() The DVI connector therefore has provision for a second link, containing another set of red, green, and blue twisted pairs. With a single DVI link, the largest resolution possible at 60 Hz is 2.75 megapixels (including blanking interval). The specification (see below for link) does, however, include a paragraph on "Conversion to Selective Refresh" (under 1.2.2), suggesting this feature for future devices. This means that the whole frame is constantly re-transmitted. No compression is used and there is no support for only transmitting changed parts of the image. The picture is transmitted line by line with blanking intervals between each line and each frame, and without packetisation. The timing of the signal almost exactly matches that of an analog video signal. A single DVI link consists of four twisted pairs of wires (red, green, blue, and clock) to transmit 24 bits per pixel. This uses transition minimized differential signaling (TMDS). The data format used by DVI is based on the PanelLink serial format devised by the semiconductor manufacturer Silicon Image Inc. ![]() If a PC's DVI output does not provide audio, it can be patched in as part of the DVI to HDMI adapter. The main difference is that DVI typically carries no audio data in its TMDS channel, although increasingly, modern PC video hardware is providing audio (e.g., cards by NVIDIA and ATI), allowing the PC to send audiovisual data to a high definition television with an HDMI input. In this way, each pixel in the output buffer of the source device corresponds directly to one pixel in the display device, whereas with an analog signal the appearance of each pixel may be affected by its adjacent pixels as well as by electrical noise and other forms of analog distortion.ĭVI is mostly compatible with HDMI. When the display is driven at its native resolution, it will read each number and apply that brightness to the appropriate pixel. The DVI interface uses a digital protocol in which the desired illumination of pixels is transmitted as binary data. It is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A). It is designed for carrying uncompressed digital video data to a display. It was developed by an industry consortium, the Digital Display Working Group (DDWG) to replace the "legacy analog technology" VGA connector standard. The Digital Visual Interface ( DVI) is a video interface standard designed to provide very high visual quality on digital display devices such as flat panel LCD computer displays and digital projectors. ![]()
