Is DVI faster than VGA on a TFT?
DVI is nothing more than a digital display interface. Just like
VGA, it operates in real time and a display card that has both VGA
and DVI will probably have the two synchronized so that they are
exactly in time with one another. They both have the ability to
operate at various frequencies and resolutions. For a given display
resolution and frequency, DVI is not faster or slower than VGA.
