It is often found on computers, televisions and video projectors that require high-definition video. Through it the video signal is sent to the monitor in digital form, thus less subject to interference.-- The DVI is now implemented in many of the latest generation video cards, and leads to a significant improvement over previous analog interfaces. The images produced by DVI interfaces are very sharp, high resolution and HDTV-ready.
