External EDID Management
The 4K Ultra HD 8x8 Matrix for HDMI features EDID Management. Before the source
can send video or audio signals, the source device reads the EDID (Extended Display
Identification Data) from the output devices connected to the matrix. The EDID contains
information about what type of audio/video data that the source can send to each output
device.
The 4K Ultra HD 8x8 Matrix for HDMI routes multiple sources to multiple output devices.
This involves reading EDID data from more than one device. Management of the EDID data
is important to maintain compatibility between all devices.
The following EDID features are copied from Output A:
• Supported Resolutions
• 3D Support
• Audio Features
Display Connections:
• If a device is not connected to Output A, then no EDID changes are made, meaning
that the previous EDID information will be used. This state will be in effect until a
display is connected to Output A and the Matrix is power-cycled.
• EDID is built from Output A to the Input. The audio block will be copied from Output A.
EDID-copying is performed only when the Matrix is reset or power-cycled.
