Question:My monitor is either blank, or the displayed image is distorted,
scrambled or smaller than I expected.
Solution: 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 correct monitor connector on your 3Dlabs Graphics Accelerator
Card. See your monitor documentation and Chapter 1 - Installation, in
this document.
Solution: Your card might not be seated properly in the appropriate slot. Remove
and reinstall your card as described in Chapter 1 - Installation .
Remember to use the anti-static wrist strap when opening your system
and handling the card.
Question:The performance of and/or the available resolutions for my 3Dlabs
Graphics Accelerator Card are not what I expected.
Solution: The 3Dlabs Graphics Accelerator Card driver may not have installed
fully, or a file may have been corrupted. Try installing the driver again.
Solution: You may have selected a display setting that is incompatible with
accelerated 3D graphics applications. See the Monitor Screen in your
3Dlabs display control panel for a list of compatible resolutions.
Solution: If the performance is different from what you expected, check to see that
the correct application or setting has been selected in the Optimized
Application Setting in the Taskbar Based Configuration Manager.
Solution: If the performance is different from what you expected, check to see that
the Wait for VBlank setting has been set correctly in the Display Control
Panel under Direct3D Support or OpenGL Support.
Question:When I restart my system, an “Invalid Display Settings” message
appears on-screen, followed by “The default display resolution has
been temporarily used by the system.”
Solution: Within a few seconds, the error messages should be replaced by a
window that allows you to set a display resolution. Pick your preferred
resolution from the list and you should get the sharp results you
expected.
