When the HDDA is completely connected and turned on it will load the Internal EDID™
automatically, which supports the highest common native video resolution and audio format of the
devices.
Example: With a mix of resolutions and audio formats the HDDA will default to the highest
common video resolution and audio format. In the diagram below the default would be 720p with
2ch audio. Multi-channel audio and 3D are not enabled on internal mode, unless all devices
support these features.
