Why doesn't the Color Control work for me?

It could be for several reasons, for example:

• Your graphic card might not support it (color controls are part of the graphic card hardware).
• The Overlay Mixer or VMR9 Video Renderers aren't in use (color Control requires either Overlay Mixer or VMR9 to work).
• When using the VMR9 (Video Mixing Renderer 9) Video Renderer, not all cards have the hardware or driver support for the color control interfaces. VMR9 is based on DirectX 9 technology and some older card may lack the hardware for color control when using VMR9. Make sure you have the latest driver when attempting this.
