EDID MANAGEMENT

Understanding EDID

The GefenToolBox 1:8 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. This required information is read from a standardized file called the EDID (Extended Display Information Data). Almost all types of output devices/displays (computer monitor, HDTV, A/V receiver) will carry and transmit its EDID to a connected source. The source will then read this EDID file and make the necessary adjustments to ensure that only compatible features are released to the device/display. A source can only accept and read one EDID from a connected device/display. Likewise, the source can only output one resolution and audio type for a connected device/display to use.

Why is EDID so important with the GefenToolBox 1:8 Splitter for HDMI with FST?

The GefenToolBox 1:8 Splitter for HDMI with FST is a complex piece of technology that replicates a single input signal to multiple outputs. The single source device will require one EDID to read. Multiple devices/displays can be connected to the outputs on the GefenToolBox 1:8 Splitter for HDMI with FST, each with its own EDID, so management of this information is key to ensure that maximum compatibility is maintained between all devices.

What options do I have to manage the EDID in the GefenToolBox 1:8 Splitter for HDMI with FST?

It is important to understand that the EDID contains much more than just listings of supported resolutions and audio formats. However, resolutions and audio formats are the two key types of information that a user will need to understand how to use these EDID management functions.

Common problems that a user may encounter while using a splitter can be:

1.Video may not be visible on all output devices/displays.

2.Audio may not be heard on all output devices/displays.

These symptoms usually arise from video resolution / audio format incompatibilities between the devices / displays connected to the splitter.

The GefenToolBox 1:8 Splitter for HDMI with FST can use one of two methods to acquire and retransmit an EDID to the A/V source device telling it about the kind of output devices that are connected to the Splitter, thus curing the incompatibility.
