Matrox Graphics Card – User Guide 29
Software setup
If a TV or VCR 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 VCR. (To connect video devices
to your computer, see page 26.)
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 VCR. To find out what standard your TV
or VCR supports, see its documentation.
* To enable TV output support for DOS display modes, use
Matrox System Utilities
. You can install this software from your Matrox
installation CD-ROM. For more information, see the
Readme
file included with this software.
Note:
In Windows 95/98, to avoid using TV settings with your computer monitor, you can
enable the
Keep optimal refresh
check box on the
DualHead Clone Options
dialog box.
