DVI is a digital video interface, video port, which is specially designed by the Digital Display Working Group (DDWG). They were intended to provide the best display devices such as LCD screens and digital projectors for customers.
DVI format uses data based on the format of panel series, Transition Minimized Differential Signaling (TMDS) uses. There are four twisted pairs to son in a single DVI, each with a color-coded red, green and blue and one of them is used to transfer a clock signal to 24 bits per pixel. The clock is almost similar to the analog video signal. The image is sent electronically, line by line with blanking intervals between each line and frame and packages. There is no compression in DVI and, if necessary, the changed portion of the image transfer, then the only way is the situation as a whole, must be repeated once.
