EDID MANAGEMENT
External EDID Management
The 1:4 Splitter for HDMI 1.3 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 Splitter.
The EDID contains information about what type of A/V data that the source can
send to each output device.
The 1:4 Splitter for HDMI 1.3 distributes a single source 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 1:
• Supported Resolutions
• 3D Support
• Audio Features
EDID color features are built based on all attached displays, using the
following rules:
• Deep Color will be
enabled
if one or more displays are connected to the
Splitter supporting Deep Color.
• xvYCC (x.v.Color) is supported if all connected displays support it.
Display Connections:
• If a display is not connected to Output 1, 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 1 and the Splitter is power-
cycled.
• EDID is built from Output 1 to the Input. The audio block will be copied
from Output 1. EDID-copying is performed only when the Splitter is reset or
power-cycled.
