Oxygen GVX1
Installing an Oxygen GVX1 Card
Setup Screen
The Setup screen lets you configure settings that are not specifically related to OpenGL.
NOTE These tools are inactive (greyed out) when the current user does not have
Windows NT administrator access.
You can enable (check) or disable (uncheck) the Configuration Manager on the Task
with a click. The default setting for the Configuration Manager is Enabled.
The Gamma Adjustment slider lets you simultaneously adjust RGB color curves and
define the color output for you display. You can also enter a precise Gamma value, rather
than use the slider, when you know which value is appropriate for you monitor and
ambient lighting conditions.
