7. EDID CONFIGURATION
The displays used within an installation usually vary from room to room, and some may not support all resolutions
available from a source. It is necessary to make sure sources will provide a video and audio format compatible with
all connected displays programmed to use them. To accomplish this, the B-120-HDMATRIX-4x4 includes built-in
EDID management for each source input. The stored EDID is per source, so all display locations will see the same
resolution and have the same audio format when that source is selected.
Note: Source is only able to output one video resolution and one audio format.
Note: The default EDID for each input is always 1080p with 2-channel stereo audio, since this format is accepted
by most displays with no issues.
The following sections explain conguring EDIDs via the included IR remote. Before conguring the EDID, be
sure to refer to the source and display manuals for available features and resolutions for each device. For more
information about using the included remote, see Section 10.1 IR Remote on page 21.
While all EDID congurations are available via the remote, the Conguration Utility can be used for faster setup.
Download the Conguration Utility and manual on the Support tab at the product page for the
B-120-HDMATRIX-4x4 at www.SnapAV.com.
What is EDID? EDID, or Extended Display Identication Data, is a stream of information sent from a display to a
source when the two devices are connected to tell the source what video and audio formats the display can use.
This prevents sources from outputting media that won’t work with the display.
7.1. Source Setup
Check each source and conrm that the audio format and video resolution are set so that they will change based
on the EDID. Normally this setting is called Auto or similar.
Note: EDID setup is not required if the source supports setting one xed video resolution and audio format.
7.2. Display Setup
It is recommended that Consumer Electronics Control (CEC) be turned OFF in all displays when using the
B-120-HDMATRIX-4x4. This will provide for proper communication of video/audio signals and allow EDIDs to
function at their optimum performance. Refer to the display’s manual for information on how to turn this function
OFF.
7.3. Auto EDID Conguration
The quickest and easiest method for conguration is to use Auto EDID. When this mode is used the matrix
switcher looks at the EDID from each of the connected displays. It uses the highest common video resolution to
create a new EDID and saves that EDID in all of the inputs.
Note: Auto EDID sets audio to 2-channel stereo for all inputs regardless of the capability of the connected displays.
If multi-channel audio is desired, embedded EDIDs or Learned EDIDs will need to be used.
When to use Auto EDID
• All sources will be available on all displays.
• As a rst step to conguration following up with advanced methods for particular displays and dedicated sources.
• For advanced EDID conguration when using a legacy display and/or dedicated sources, use embedded EDIDs
or learning as described in the following sections.
