Description

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 While DVI technology has superseded VGA technology, both specifications are often included in personal computers, with VGA technology being much more common in laptop computers than desktop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.

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.

At the electrical level, these pairs are highly resistant to electrical noise and other forms of analog distortion.

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.

Single Link and 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.

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. 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. 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. Intel Newsrom – Leading PC Companies Move to All Digital Display Technology, Phasing out Analog (8. December 2010)Like other ways of transmitting video, there are two different regions: the active region, where pixel data is sent, and the control region, where synchronization signals are sent. The active region is encoded using transition-minimized differential signaling, where the control region is encoded with a fixed 8b/10b encoding. As the two schemes yield different 10-bit symbols, a receiver can fully differentiate between active and control regions. 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. Unified Display Interface (UDI) was proposed by Intel to replace both DVI and HDMI, but was deprecated in favor of DisplayPort. Some DVD players, HDTV sets, and video projectors have DVI connectors that transmit an encrypted signal for copy protection using the High-bandwidth Digital Content Protection (HDCP) protocol. Computers can be connected to HDTV sets over DVI, but the graphics card must support HDCP to play content protected by digital rights management (DRM).
