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 1:4 Splitter for HDMI has advanced EDID management 
features to ensure complete compatibility with all sources and display 
devices. See pages 7-10 for more details.
