READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 1:8 SPLITTER FOR HDMI 1.3
• EDID contains the A/V capabilities of a display device in regards to video
resolutions and audio formats supported. This information is used by the
source device to determine the format of the A/V signal it outputs. The
GefenToolBox 1:8 Splitter for HDMI 1.3 has advanced EDID management
features to ensure complete compatibility with all sources and display
devices. Please see pages 7-10 for more details.
• The GefenToolBox 1:8 Splitter for HDMI 1.3 detects the presence of Deep
Color automatically and disables Deep Color EDID features across all
outputs if any connected device or display is not capable of Deep Color.
This automatic behavior insures compatibility among all output devices in a
mixed-device environment. This feature cannot be disabled.
