EDID MANAGEMENT
External EDID Management
The GefenToolBox 1:4 Splitter for HDMI features EDID Management. Before the
source can send video or audio signals to the display, the source devices reads
the EDID (Extended Display Identifi cation Data) of each device connected to
an output. The EDID contains information about what type of A/V data that the
source can send to each display.
GefenToolBox 1:4 Splitter for HDMI 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.
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 copied from Output 1 to all other outputs. The audio block will be
copied from Output 1. EDID-copying is performed only when the Splitter is
reset or power-cycled.
3DTV Support
• 3D signals are supported if a 3DTV is connected to Output 1.
Deep Color
• Deep Color will be disabled if one of more other displays connected to the
Splitter do not support Deep Color.
