The Digital Visual Interface standard is a video interface standard covering the transmission of video between a source device (such as a personal computer) and a display device (such as a monitor or digital TV). The DVI standard has achieved widespread acceptance in the computer industry for both desktop computers and monitors. Most contemporary retail desktop computers and LCD monitors feature a DVI interface, and many other devices, such as projectors and consumer televisions, quangphucau.com DVI indirectly through HDMI, another video interface standard.
