44 Dynamic Pictures Oxygen 3D Family
Software Troubleshooting
Problem : I installed a new driver (either from the Oxygen CD-ROM or
from the Dynamic Pictures web site), and the available resolution(s) or
performance is not what I expected.
Solution : You may not have fully installed the Dynamic Pictures driver
or an installed driver file may have been corrupted. You can confirm if
the driver is installed and its version number by using the Oxygen
control panel (Figure 15). It should be the same as the version number
of the driver you most recently installed. You can also use the “Test”
button on the
Support Information page in the Oxygen control panel to
verify successful installation.
When driver file corruption occurs, it is often a result of a media error
or a communications error during the download procedure. Try
downloading and/or installing the driver again.
Alternatively, you may have selected a display setting that is
incompatible with accelerated 3D graphics. For example, the Oxygen
202 can support a maximum resolution of 1280x1024 when
accelerating 3D graphics in true color mode. Selecting a true color
resolution higher than this will greatly reduce performance. Refer to
the
Monitor Resolutions Tables on page 38 to select a setting that offers
hardware accelerated 3D graphics.
You must restart your system for the new driver to be loaded by the
Windows NT operating system.
Problem : After installing my software and Oxygen card, or after
selecting a new resolution, when restarting my computer Windows
displays the message, “Invalid Display Settings” and “The default
display resolution has been temporarily used by the system.”
Solution : You should soon see a window that allows you to select a
display resolution. Once you have selected your preferred resolution,
your Oxygen card should work as expected.
