Problems During Application Development - Matrox Orion Installation And Hardware Reference

48 Appendix A: Troubleshooting
The picture quality is poor, with a dim picture, poor
contrast, and poor sharpness.
The monitor might be improperly adjusted.
Adjust the brightness, sharpness, and contrast controls of
your monitor.
Ensure that the cable is correctly and completely inserted at
both ends.
Make sure that the RGB input switches are set to 75 ohms.
The picture is broken up, with bad horizontal sync; in
other words, it rolls, jitters, or blinks.
The cables connected to the monitor might not be attached
properly or the monitor might not accept Matrox Orion's video
settings.
Ensure that the synchronization line(s) are properly
connected to your monitor (to identify the sync line(s), refer
to the appropriate monitor configuration in the ' Connecting
to a monitor' section of Chapter 2). If this does not solve the
problem, your monitor might need horizontal setting
adjustments, or it might be defective. Refer to your monitor's
manual.
Ensure that the resolution you specified is valid for your
monitor.

Problems during application development

I'm running an application and the computer 'hangs' or
produces unwanted results.
Check for an interrupt, memory or register conflict. Sometimes,
an EISA or ISA device might attempt to use the same
interrupts, register or memory space as Matrox Orion, and this
causes a conflict.
