Note:
In DualHead Multi-Display mode under Windows 2000, Windows treats the main
and secondary displays as a single display (which the Matrox display driver divides between
two monitors). As a result, these displays always use the same resolution and color palette
settings. The resolution of both displays is limited by the display with the lower maximum
resolution.
