The basic differences between an analog display adapter and a DVI (digital) display

On the DVI cable, the images arrives

a digitally signal before it can be processed and shown.

connecting to a LCD display? Well yes an no. On the visual level there
are not that many user perceivable differences in display quality that you will notice.
