Troubleshooting

If you have trouble using your Oxygen GVX420 card or a 3D application, you may find the answer to your
problem in the following sections. Always start your problem- solving efforts with the simplest solution and
work up to the more complex ones.

My monitor is either blank, or the displayed image is distorted, scrambled or smaller than

I expected.

If the monitor is blank, be sure that your system and monitor are plugged in and turned on.
Is the monitor’s power cord attached securely? Check each component’s documentation for
the location and use of power connectors and switches.

Solution:

Make sure that your video cable is connected securely to the monitor and to the monitor
connector on your Oxygen card. See your monitor documentation and Chapter 1 -
Installation, in this document.
