The Permedia3 Create! Driver
Chapter 2 - Software Configuration 12
Setup Screen
The Setup screen lets you configure settings that are not specifically related to Open GL or
DirectX.
• You can enable (check) or disable (uncheck) the Task-bar based
Configuration Manager with a click. The default setting for the
Configuration Manager is Enabled.
• The Optimal Refresh Rate field displays the preferred refresh rate for your monitor. If
it is available, Permedia3 Create! will use it. If that refresh rate is not available,
Permedia3 Create! will use the next available lower rate.
• The Gamma Adjustment slider on the Setup screen lets you simultaneously adjust
RGB color curves and define the color output for your display. You can also enter a
precise Gamma value, rather than use the slider, when you know which value is
appropriate for your monitor and ambient lighting conditions.
