What is DVI and how does it work?
DVI, or Digital Visual Interface, is a video interface standard designed to maximize the visual quality of digital display devices such as flat-panel displays, digital projectors, and HDTVs. It was introduced in 1999 and was widely used for connecting computers to display devices. DVI transmits digital video signals, which are less prone to degradation and interference compared to analog signals. This results in a sharper and more accurate image on the display device. DVI connectors can carry both digital and analog signals, making them compatible with a wide range of devices.
The DVI interface works by transmitting digital video signals from a source device, such as a computer graphics card, to a display device. The signal is transmitted through a DVI cable, which can be up to 4.5 meters long. DVI supports a range of resolutions, from 640×480 up to 2560×1600, depending on the type of DVI connector used. There are several types of DVI connectors, including DVI-A (analog only), DVI-D (digital only), and DVI-I (both analog and digital). The type of connector used determines the type of signal that can be transmitted and the maximum resolution supported.
When was DVI phased out and what replaced it?
DVI was phased out in the mid to late 2000s, as newer digital display interfaces such as HDMI and DisplayPort became widely adopted.
