of Blue (U), and the color difference of Red (V). RGB does this by using the gradation of the 3 colors, Red
(R), Green (G), and Blue (B).

This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors.
One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and
analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
