Catalyst has built-in screen gamma correction, that adjusts the entire output - not just an individual layer.

Use the HUD - -'Screen Presets', you can select a gamma curve preset which changes the contrast, black level, white level, saturation, colour balance of the entire screen or projector.

You do not need to rerender any footage. this is totally non-destructive. easy to use, and does not need any other software.

Each catalyst output can have a different output.

Select a menu option, and you will see a great difference in output levels.
