The DVI port has succeeded the VGA port. It was developed in 1999 and was designed to provide uncompressed, high-quality video to LCD monitors. Now there are three different versions of a DVI standard. There's DVI-A whose 'A' stands for analog. And is used to send only analog signals. There's DVI-D where the 'D' stands for a digital. And this is used to send only digital signals. And there is also DVI-I where the 'I' stands per integrated which is used to send both analog and digital signals. Now on the ports that are able to send digitals, which would be the DVI-D and DVI-I, there are two different potions in the DVI standard. There is single link and dual link.Dual link has six extra pins and these pins are what allows for a higher resolution than single link. Dual link DVI doubles the video bandwidth which has a max resolution of 2560*1600, whereas single-link DVI has a max resolution of 1920*1600. And the DVI and adapter will typically have a white color.
