3. Make sure the display is plugged in and switched ON.
4. Make sure the display video cable is correctly connected.
5. If you are using a high-resolution display, make sure its input switches are set to 75
ohms.
6. Turn OFF the display, and unplug it from the power outlet. Examine the video cable
pins. If they are bent, carefully straighten them.
If your PC has a Matrox video adapter board and the screen is blank or the picture is
fragmented, the high-resolution display may not accept the board's video parameters.
1. Set the display's RGB inputs (and sync switches if available) to 75 ohms,
external
sync.
2. Make sure a fixed-sync high-resolution display accepts the vertical and horizontal
refresh rates of the resolution you are using. (Refer to
Some of the Available Video
Resolutions
in “Technical Information,” and
Using the Matrox Video Software Tools
in
“Configuring Your PC”.)
If a high-resolution display shows spurious colors:
1. Make sure the Red, Green and Blue lines are connected to their corresponding inputs
on the display.
2. Make sure your display's RGB inputs are set to 75 ohms.
3. The video settings may not be correct for the display.

PC”.)
If the display image does not align with the screen (usually when you change resolutions),
use the display's controls to center the image. (Refer to the display's manual.)
If the screens produced by the applications look wrong:
1. Check the application manual to find out which video standard is required.
2. Check your display manual to find out which refresh rate is required.
3. Check that you are using the correct video driver for your display.
If you changed the display resolution in Windows, you may have selected a resolution not
supported by your display.
1. Start the PC from a diskette containing the operating system.
2. Run Windows Setup from the
C:\WINDOWS
directory and select a supported video
resolution. (Refer to your display manual.)
