Software setup
*
If a TV or video recorder is connected to the second monitor connector on your Matrox graphics card,
you can use TV output mode to view or record your display on your TV or video recorder.
(To connect video devices to your computer,
see page 18
.)
While in TV output mode, your computer display may use TV settings. TV settings have lower
resolutions and refresh rates than typical computer monitor settings. Lower refresh rates may result
in more noticeable flicker.

WARNING:
Because some computer monitors don’t support TV settings, a computer
monitor may become garbled or unusable if it uses TV settings. If this happens, you can
simply turn off your computer monitor and use your TV to view your computer display.
Also, some computer monitors may be damaged if they use the 50 Hz vertical refresh rate
used with European TV settings. For more information, see your monitor manual.
Note:
Two TV standards are supported for TV output. The NTSC standard is used in North
America and Japan, among other places. The PAL standard is used in most of Western
Europe and in China, among other places.
If an incorrect TV standard is selected in Matrox software, the output from your computer
may not appear or record properly on your TV or your video recorder. To find out what
standard your TV or video recorder supports, see its documentation.
† Under Windows NT 4.0, the DualHead DVDMax feature isn’t supported.
