•
Bus-master capable slot: If you still do not see anything on
your monitor, your Oxygen card may not be in a bus master-
capable slot in your computer. On some PCs, not all slots are
bus master-capable slots. Consult your computer or
motherboard documentation for more information on your
PCI bus and master-capable slots.
•
VGA jumper disabled: Is the VGA jumper on your Oxygen
card set to the factory position, "VGA enabled"? Compare the
jumper on your card to the illustration on page 62. Your
Oxygen card must have VGA enabled to display VGA mode
2D graphics on your monitor. See
Appendix C: Using Dual
Oxygen Cards for additional details on setting your VGA
jumper.
•
Multiple displays: Not all computers support multiple video
cards simultaneously. If you are attempting to use more than
one video card and monitor, you may wish to contact your
computer or motherboard manufacturer to confirm that this
is a supported display configuration.
•
VGA Jumper enabled using two Oxygen cards: If you are
using two identical Oxygen cards to drive two monitors, you
must disable VGA on one of the Oxygen cards. Refer to
Appendix C: Using Dual Oxygen Cards for more information
about switching your VGA jumper.
Problem : My monitor is either not displaying anything, or displaying
something, but what is displayed is distorted, scrambled or smaller
than I expected.
Solution : Your vertical refresh may be set higher than your monitor is
capable of displaying. Displaying at a refresh rate that is too high can
damage your monitor. Select a lower refresh rate using the Display
Control Panel. For more information about your monitor and vertical
refresh rates, see the manual that accompanied your monitor.
