10 Running the Automated EDID Tests on HDMI Source Devices
This section provides procedures for running the optional Auto EDID test on HDMI source devices.
The HDMI Auto-EDID Test is included only if you have purchased the Auto EDID Test option.
10.1 HDMI Auto EDID Test
The Auto EDID Test enables you to verify that an HDMI source (or upstream HDMI network) properly handles a
series of EDIDs. The test checks the incoming timing against what is expected based on the contents of the
EDID such as the preferred timing. The test also verifies that the video parameters are consistent with the
capabilities of the EDID that is emulated. The 780B is configured with a set of EDIDs that it will emulate on its
HDMI Rx port. The EDIDs can be commercial EDIDs, test EDIDs or even known-bad EDIDs. The HDMI source
is connected to the HDMI Rx port and the test is initiated. The results are presented on the embedded screen.
As an option you can define a report for later viewing and dissemination to other colleagues and subject matter
experts.
10.1.1 Procedures for Configuring a Set of EDIDs for the Auto EDID Test
This subsection provides procedures for configuring the 780B with the desired set of EDIDs for testing. Note
that the test comes with a default set of EDIDs for running the test. However, typically you will want to create
your own set of test EDIDs. You will have to create a text file with the names (and descriptions) of the EDIDs
that you wish to use for testing.
Quantum Data offers an EDID Library free of charge which has a variety of EDIDs for use in testing. The EDID
Library provides details procedures on how to download and install EDIDs on a PC. The procedures below
assume that you have a set of EDIDs on your PC that you wish to use for the Auto EDID test. This procedure
also assumes that you have transferred those EDIDs into the EDID directory of the 780B. Refer to the section
in this manual
Adding Reference EDIDs for Use in Testing HDMI Devices for instructions on transferring EDIDs
into the proper directory of the 780B.
1. Open up your favorite text editor program (example Notepad). Create a text file listing the EDIDs. Each
EDID listing in the file is structured as follows:
<name> <description>
Where name is the name of the EDID as it appears in the 780B file system and description is the name you
assign and appears in the Name field on the Auto EDID test results screen. The following is an example of
the text file:
