This is a new DAC chip that does real-time anti-aliasing, achieving the above
virtual resolution. It does not really increase the resolution nor the colors,
but after doing proper anti-aliasing (ie. getting rid of the pixel jaggies)
it achieves a pictures that is equivalent to the above resolution/colors.

Although it is a direct replacement for most current VGA DACs you must have
proper drivers to take advantage of it. Some VGA makers a reported to come
out with VGA cards soon that contain the chips and have drivers for AutoCAD,
and Windows 3.0.
