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. 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 ensure a basic level of interoperability, DVI compliant devices are required to support one baseline display mode, "low pixel format" (640×480 at 60Hz).

DVI stands for Digital Visual Interface. It is a video display interface developed by Digital Display Working Group (DDWG). The interface is used for connecting display devices to PC or smart unit and it was developed with the intention of creating a standard for transferring digital video content. The DVI connector is used to establish this interface. 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.

Retrieved 31 January 2023.As I mentioned earlier, DVI and VGA are dying standards, but they still have some practical uses. DVI-I is good because it can support modern resolutions (1080P at 60Hz) and you can easily convert it to other connector types. Most analog connectors, such as VGA, require active adapters to convert to HDMI, but you don’t need that with DVI. Manchester, Gary (October 7, 1996). "Molex PnD intellectual property letter" (PDF). Archived from the original (PDF) on February 22, 2003. With televisions, HDMI is the most common connector. But if you want to connect a computer to your TV (or you've got a new computer monitor), the options tend to be HDMI, DisplayPort, DVI, and sometimes old-school VGA.

The Intel/Apple love child of Thunderbolt is technically only available on one monitor ( Apple Thunderbolt Display). There are likely to be more, but don't expect some sort of Thunderbolt revolution. The connection is compatible with Mini DisplayPort. 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. Specifications [ edit ] A passive DVI-to-VGA adapter. This adapter will not work with a DVI-D output. It requires a DVI-I or DVI-A output to get the analog signal to a VGA input (even if the adapter looks like a DVI-D). A more expensive active adapter (or converter) is required to connect DVI-D to VGA. Digital [ edit ]However, DVI-D will require an active adapter, something like this one. The good news is DVI has a pink for +5V so these adapters can take the power they need directly from the device without needing an external power supply, like VGA to HDMI adapters need. Overall, converting DVI to other connector types is very easy with inexpensive adapters.

DVI-I (Digital Video Interface - Integrated): As the name suggests DVI-I supports both analog and digital signals but not both at the same time. The user has to choose the type when both are supported at the other end. DVI-I port can be connected to both VGA monitors and HD monitors. There are two types in DVI-I. They are Single Link DVI-I and Dual Link DVI-I. The pin configuration for both is given below. You can see in pin diagram the DVI-I pins are a combination of both DVI-A and DVI-D. DVI-I (Single Link) supports a video stream at 1920X1200 @ 60 Hz. DVI-I (Dual Link) support a video stream at 2560X1600 @ 60 Hz.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.
