8.3. Auto 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-500-MTRX-230-4X4 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 configuring EDIDs via the included IR Remote. Before configuring 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 11.1 IR Remote on page 21.
While all EDID configurations are available via the remote, the Configuration Utility can be used for faster setup.
Download the Configuration Utility and manual on the Support Tab for the B-500-MTRX-230-4X4 at www.SnapAV.com.
What is EDID? EDID, or Extended Display Identification 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.
Check each source and confirm 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 fixed video resolution and audio format.
It is recommended that Consumer Electronics Control (CEC) be turned OFF in all displays when using the B-500-MTRX-
230-4X4. 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.
The quickest and easiest method for configuration 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 2ch 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 first step to configuration, following up with advanced methods for particular displays and dedicated sources.
Note:
For advanced EDID configuration when using a legacy display and/or dedicated sources, use embedded EDIDs
or learning as described in the following sections.

8.3.1. How to Configure Auto EDID
To set up Auto EDID configuration, first make sure that all displays are powered on and connected to the matrix switcher.
Then, press the following remote buttons in this order. Be sure to press each button within 10 seconds of the previous
button-press to prevent the command from resetting.
