The Full Screen Renderer supports a static set of display modes. By default, every mode is enabled. You can use this method to enable or disable a particular display mode. The video card on the user's system might not support every mode. The Full Screen Renderer will not use a mode that the video card does not support, even if that mode is enabled. To determine whether the card supports a particular mode, call the IFullScreenVideoEx::IsModeAvailable method. If a mode is disabled, the Full Screen Renderer will not use it, even if the card supports it.

Display modes are indexed from zero. The IFullScreenVideoEx::CountModes method returns the number of modes. To retrieve the width, height, and bit depth of a particular display mode, call the IFullScreenVideoEx::GetModeInfo method.
