EDID MANAGEMENT Understanding EDID The GefenToolBox 1:4 Splitter for HDMI with FST features automatic and manual EDID adjustments to maximize compatibility of all attached devices. First it is necessary to understand EDID and what it is used for. EDID. What is it and what is it used for? Under normal circumstances, analog (i.e. VGA computer) and digital (i.e. Blu-ray player) source devices will require information about a connected device/display to assess what resolutions and features are compatible.
EDID MANAGEMENT EDID Mode Selection 1. EXTERNAL MODE: To use this mode, set the EDID Mode Switch on the front panel to the EXT position. In External EDID mode, the Splitter directly retrieves EDID data from each connected A/V display device and builds a new EDID created from the highest common video resolution that all display devices can use together and the highest audio capability. This new EDID is sent back to the source device.
EDID MANAGEMENT Audio Channel Selection The GefenToolBox 1:4 Splitter for HDMI with FST features a switch that will modify the supported audio formats listed in the pre-programmed EDID. This feature is useful for limiting the output of the source device to either 2 or multichannel audio formats. NOTE: This selector switch will only affect the pre-programmed EDID in the INTERNAL (INT) EDID Mode.
EDID MANAGEMENT External EDID Management The 1:4 Splitter for HDMI with FST features EDID Management. Before the source can send video or audio signals to the display, the source devices reads the EDID (Extended Display Identification 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. The 1:4 Splitter for HDMI with FST distributes a single source to multiple output devices.
