Analog (VGA) displays require that the original digital signal from the
video card processor be converted to an analog signal (still in the video
card). This analog siganl then travels over the VGA cable to the monitor
where the signal must now be converted from analog back to a digital siganl
that the monitor can use. All of this extra signal processing degrades the
signal and thus the image you see on the screen.
With a digital input monitor, the digital siganl from the video processing
unit in the video card is sent straight out over the digital video cable to
the digital input on the monitor and is directly used. Result: much
sharper, less noisey image.
