Matrox Graphics Card – Installation Guide 19
Solution Make sure the 15-pin connector to your Matrox graphics card
is firmly in place.
Solution If your monitor uses a 15-pin connector, make sure the
connection to the monitor is firmly in place.
Solution If your monitor uses BNC input, make
sure the Red, Green, Blue, Horizontal
Sync (HSYNC – white or gray wire),
and Vertical Sync (VSYNC – black
wire) connections are firmly in place
and plugged into the correct input.
Cause If your monitor uses BNC input, one or more connection settings may be incorrect.
Solution Set each of your monitor’s RGB input and sync switches (if available) to 75 ohms,
with the sync set to “external”. These controls are usually switches on the back of
your monitor.
Problem After the startup screen, or after display settings are changed,
the screen image is garbled or unusable
(blank screen, rolling or overlapping screen images)
Cause
The Matrox display driver may be trying to use settings your monitor doesn’t
support. This can happen if a monitor was never selected in the software and the
display resolution was changed to one your monitor doesn’t support, or if the monitor
connected to your computer was changed without it being changed in the software.
Solution Windows 95/98:
1 Press [Ctrl]+[Alt]+[Del] twice to restart your computer.
2 Before Windows starts, press [F5] to enter “safe mode”.
3 Right-click the Windows desktop background, then click Properties  Settings.
4 Move the Desktop area (Windows 95) or Screen area (Windows 98) slider
down to its lowest setting, then click
OK.
5 Restart your computer normally.
6 Select a monitor with the Matrox Monitor property sheet, then you can adjust
your display settings. For more information, see the online Matrox PowerDesk
