„ DualHead Clone – View a copy of your main display on your secondary display. Each
display can use different monitor settings (refresh rates).
„ DualHead DVDMax – Play digital video in a window on your main display and, at the same
time, view that video full-screen on a TV.
„ DualHead Zoom – Use your secondary display to view a zoomed-in portion of your main
display.
Note: The Matrox display driver for Windows 95/98 supports multiple displays with
Windows 98. For more information on multi-display mode, see Windows 98 online help
under “Multiple Display support”. (Windows 95 doesn’t support multiple displays.)
Note: In multi-display mode under Windows NT 4.0, the same display resolution and color
palette is used for each display.
