Product Information

Featuring support for analog connections, DVI devices manufactured as DVI-I are compatible with the analog VGA interface [1] by including VGA pins, while DVI-D devices are digital-only. 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). [2] Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players. Intel Newsrom – Leading PC Companies Move to All Digital Display Technology, Phasing out Analog (8. December 2010) DVI is the only widespread video standard that includes analog and digital transmission in the same connector. [13] Competing standards are exclusively digital: these include a system using low-voltage differential signaling ( LVDS), known by its proprietary names FPD-Link (flat-panel display) and FLATLINK; and its successors, the LVDS Display Interface (LDI) and OpenLDI.

In addition to digital, some DVI connectors also have pins that pass an analog signal, which can be used to connect an analog monitor. The analog pins are the four that surround the flat blade on a DVI-I or DVI-A connector. A VGA monitor, for example, can be connected to a video source with DVI-I through the use of a passive adapter. Since the analog pins are directly compatible with VGA signaling, passive adapters are simple and cheap to produce, providing a cost-effective solution to support VGA on DVI. The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so even if the four analog pins were manually removed, it still wouldn't be possible to connect a male DVI-I to a female DVI-D. It is possible, however, to join a male DVI-D connector with a female DVI-I connector. [12] One of the purposes of DVI stream encoding is to provide a DC-balanced output that reduces decoding errors. This goal is achieved by using 10-bit symbols for 8-bit or less characters and using the extra bits for the DC balancing. HDMI is a newer digital audio/video interface developed and promoted by the consumer electronics industry. DVI and HDMI have the same electrical specifications for their TMDS and VESA/DDC twisted pairs. However HDMI and DVI differ in several key ways.DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics.

The DVI specification includes signaling for reducing power consumption. Similar to the analog VESA display power management signaling (DPMS) standard, a connected device can turn a monitor off when the connected device is powered down, or programmatically if the display controller of the device supports it. Devices with this capability can also attain Energy Star certification. Video signals transmitted over DVI need no such conversion because they are digital-only. Consequently, picture quality is better. The difference may not be noticeable for text or even SD (standard definition) video but can be seen for HD videos and hi-resolution images or on hi-res displays.Because P&D was a physically large, expensive connector, a consortium of companies developed the DFP standard (1999), which was focused solely on digital video transmission using a 20-pin micro ribbon connector and omitted the analog video and data capabilities of P&D. [4] :3 [5] :4 DVI instead chose to strip just the data functions from P&D, using a 29-pin MicroCross connector to carry digital and analog video. [8] Critically, DVI allows dual-link TMDS signals, [9] meaning it supports higher resolutions than the single-link P&D and DFP connectors, which led to its successful adoption as an industry standard. Compatibility of DVI with P&D and DFP is accomplished typically through passive adapters that provide appropriate physical interfaces, as all three standards use the same DDC/EDID handshaking protocols and TMDS digital video signals. [10] :§1.3.7 Technical overview [ edit ] IEEE 1394 was proposed by High-Definition Audio-Video Network Alliance ( HANA Alliance) for all cabling needs, including video, over coax or 1394 cable as a combined data stream. However, this interface does not have enough throughput to handle uncompressed HD video, so it is unsuitable for applications such as video games and interactive program guides. Eiden, Hermann (July 7, 1999). "TFT Guide Part 3 - Digital Interfaces". TomsHardware.com . Retrieved 29 March 2012. DVI offers a higher quality signal compared to VGA. The difference is especially noticeable at higher resolutions. The video quality is a factor of the mechanism of operation and the length and quality of the cable; both are discussed below.

DVI'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).

There is a lot of misinformation in this article. There is no better way to convey a pure RGB video signal than a pure RGB high-quality analog link. This is what all other technologies are compared to. Unified Display Interface (UDI) was proposed by Intel to replace both DVI and HDMI, but was deprecated in favor of DisplayPort.

To make it easier to understand, most graphics cards have at least one dual-link DVI port, single-link DVI-I is kind of dated. DVI-D is the digital format connector. It comes in both single-link and dual-link formats, the difference being that the dual-link connector provides more power and twice the data transmission rate compared to the single-link connector. DVI-D is the most popular type of connector for hooking up DVI cards to LCD monitors. For large screens, the dual-link connector is often a better choice than the single-link connector. a b "Digital Visual Interface Revision 1.0" (PDF). Digital Display Working Group. 2 April 1999 . Retrieved 31 January 2023. DVI stands for Digital Audio Interface and it was an attempt to create an industry standard for video connectors, a seat which HDMI has now filled. The technology is a little dated, but like VGA, it’s still common on computers, monitors, TVs, and other displays.To convert DVI to HDMI you’ll need a passive physical adapter. The good news is both DVI-I and DVI-D can be converted to HDMI because they both use digital signals. DVI-I Dual Link has a maximum resolution of 2560×1440 at 60 Hz. You can push it higher but you’ll have to lower the Hz rate to 30 which is a little clunky. DVI-I is the integrated format connector. It works with digital and analog equipment, acting as a DVI-D or DVI-A cable, but it won't convert pure DVI-D output to analog. DVI-I has two variations—single-link and dual-link—and has a 29-pin layout to accommodate multiple connections.
