Product Information

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. In some cases, DVI can carry over audio when connected to a physical HDMI adapter. For more information about that, take a look at this article. If you have the option to use HDMI or another port liked Display Port, use those instead, DVI and VGA should only be used as a last resort because the quality isn’t the best. DVI (Digital Visual Interface) is a hardware specification for computers and display equipment that is similar to VGA. DVI-D (Digital Visual Interface Digital) refers to DVI technology that is used exclusively with digital devices, while other versions of DVI can be used with analog devices. While VGA technology was made for analog computers, DVI technology is more modern and is intended for digital computers and display equipment, such as monitors and projectors. While VGA and DVI produce similar quality on regular monitors, DVI produces much higher picture quality on LCD monitors and other high-definition equipment. a b "Digital Visual Interface Revision 1.0" (PDF).

However, DVI-I and DVI-D are still found on monitors and computers. I won’t be talking about DVI-A in this article because it’s rarely used today. 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.

It provides DC power as well. If a depth greater than 24 bits per pixel is desired, the least significant bits are sent on the second link.

How to Convert DVI to VGA

The DVI connector on a device is given one of three names, depending on which signals it implements: Generalized Timing Formula (GTF) is a VESA standard which can easily be calculated with the Linux gtf utility. Coordinated Video Timings-Reduced Blanking (CVT-RB) is a VESA standard which offers reduced horizontal and vertical blanking for non-CRT based displays. [15] Digital data encoding [ edit ] Some DVI-D sources use non-standard extensions to output HDMI signals including audio (e.g. ATI 3000-series and NVIDIA GTX 200-series). [17] Some multimedia displays use a DVI to HDMI adapter to input the HDMI signal with audio. Exact capabilities vary by video card specifications. DVI devices manufactured as DVI-I have support for analog connections, and 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.

DVI made its way into products starting in 1999. One of the first DVI monitors was Apple's original Cinema Display, which launched in 1999. DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link) When DVI was designed, most computer monitors were still of the cathode ray tube type that require analog video synchronization signals. The timing of the digital synchronization signals matches the equivalent analog ones, so the process of transforming DVI to and from an analog signal does not require extra (high-speed) memory, expensive at the time.You can also convert VGA to DVI because DVI supports analog signals too. Do remember that only DVI-I supports both analog and digital, DVI-D only works with digital, so you’ll need an active adapter to convert that to another type of connector.

Digital Visual Interface ( DVI) is a video display interface developed by the Digital Display Working Group (DDWG). 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. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content. Most modern graphics cards have abandoned VGA ports but they still have one or more DVI ports. It’s rumored these connectors will be abandoned soon too. DVI connectors use digital signals, and the DVI-I version has a couple of pins for analog signals, so you can easily convert to VGA with a simple port converter (more on that later). VGA (Video Graphics Array) is a hardware specification for display monitors and computers that allows a computer to display applications on a VGA-based monitor via a VGA cable. VGA technology is one of the oldest forms of display hardware in computing and is outfitted in virtually every computer system in the world. VGA uses analog signals but is compatible with most digital devices. While DVI technology has superseded VGA technology, both specifications are often included in personal computers, with VGA technology being much more common in laptop computers than desktop computers.
