Designing and Configuring Video/Audio EDID
NOTE: HDMI inputs support both video and audio EDID. DVI and VGA
inputs support video EDID only.
EDID (Extended Display Identification Data) describes the video and audio
capabilities of a display. EDID resides in a display and is read by a source
device. The source device uses the EDID to determine the best resolution/
audio format to output.
As part of the system design process, EDID design is as important as the
selection of sources, displays, and DM components. Designing an EDID
configuration and manually setting the EDID ensures that all source devices
provide the output that meets the expectations of the end user.
When designing an EDID configuration, consider the following scenarios:
● Scenario 1: Source devices are user-provided laptops, and end
users expect laptop mirroring. For best results, include the native
resolution of each laptop in the EDID configuration. To achieve this, select
several popular resolutions and ensure that all selected resolutions are
supported by all displays in the system. A variety of laptops can then
display their native resolution while also sending that resolution to the
displays.
● Scenario 2: Source devices are not user-provided laptops. Select the
preferred resolution based on the capabilities of the displays in the
system. If all displays do not share the same native resolution, determine
whether there is a common resolution among the displays. Select only
that resolution in the EDID configuration. The addition of multiple
resolutions to the EDID configuration is not necessary when controlling
the source device.
A DM switcher provides configurable video/audio EDID for each input.
To configure video/audio EDID, use DMTool in Crestron Toolbox™. DMTool
allows the EDID configuration to be set manually while ensuring that the EDID
is accurate. For detailed information about configuring video/audio EDID, refer
to the Crestron Toolbox help file.
The “Link Quality” dialog box provides link status indications as listed in the
following table.

Using DMTool, test the link status of DM 8G multimode fiber, DM 8G SM
(single-mode) fiber, and DM 8G+ cable connections between the DM switcher
and a DM transmitter, DM receiver, or other DM switcher.
To test cable link status, do the following. In the
DM switcher tab within DMTool, click the LQ
(link quality) button for the output whose DM 8G
fiber, DM 8G SM fiber, or DM 8G+ cable
connection is to be tested.
The “Link Quality” dialog box appears, displaying
the link status of the cable connected to a DM 8G
fiber, DM 8G SM fiber, or DM 8G+ connector of
a DM transmitter, receiver, or other DM switcher.

Green Link is good. No errors have been detected. No action is required.
Yellow Link is fair. Video may be present; however, some errors have
been detected. Check cable connections. Using a
cable tester, check cable terminations.

detected. Check cable connections. Using a cable
tester, check cable terminations.
Link is down. Video is not present. Cable is unplugged or
disconnected from downstream device. Check cable
