EDID Management

EDID (Extended Display Identification Data) is a collection of data cached inside

all modern displays that describes the unit's capabilities. The EDID information

is defined by a standard published by the VESA (Video Electronics Standards

Association) and includes information such as the manufacture's name, model

number, supported resolutions and video timings, supported audio formats, color

space, etc. During boot-up, a source device must be able to read the EDID of the

connected display. When using a splitter, it is necessary that the EDID from one

of the connected displays is passed back to the source device. The EDID value

used is critical to the performance of the system as a whole.

On the front of the unit there is an EDID selection switch. This switch controls

what EDID information the splitter will report to the source device. The EDID

information provided to the source can either be EDID from one of the connected

displays (AUTO EDID Mode) or from an on-board memory chip that contains a

library of the most commonly used resolutions (INT EDID Mode). These internally

stored resolutions are listed in the table below.

When set to the AUTO position, the splitter will automatically discover and apply

the EDID based on a predetermined selection hierarchy as follows:

When the splitter powers ON, it automatically begins the EDID discovery process

by sequentially scanning the connected displays on all outputs, starting with
