780C Multi-Interface Interoperability Tester – User Guide Page 181September 29, 2014 Revision A110 Running the Automated EDID Tests on HDMI Source DevicesThis 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 TestThe Auto EDID Test enables you to verify that an HDMI source (or upstream HDMI network) properly handles aseries of EDIDs. The test checks the incoming timing against what is expected based on the contents of theEDID such as the preferred timing. The test also verifies that the video parameters are consistent with thecapabilities of the EDID that is emulated. The 780C is configured with a set of EDIDs that it will emulate on itsHDMI Rx port. The EDIDs can be commercial EDIDs, test EDIDs or even known-bad EDIDs. The HDMI sourceis 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 matterexperts.10.1.1 Procedures for Configuring a Set of EDIDs for the Auto EDID TestThis subsection provides procedures for configuring the 780C with the desired set of EDIDs for testing. Notethat the test comes with a default set of EDIDs for running the test. However, typically you will want to createyour own set of test EDIDs. You will have to create a text file with the names (and descriptions) of the EDIDsthat 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 EDIDLibrary provides details procedures on how to download and install EDIDs on a PC. The procedures belowassume that you have a set of EDIDs on your PC that you wish to use for the Auto EDID test. This procedurealso assumes that you have transferred those EDIDs into the EDID directory of the 780C. Refer to the sectionin this manual Adding Reference EDIDs for Use in Testing HDMI Devices for instructions on transferring EDIDsinto the proper directory of the 780C.1. Open up your favorite text editor program (example Notepad). Create a text file listing the EDIDs. EachEDID listing in the file is structured as follows: Where name is the name of the EDID as it appears in the 780C file system and description is the name youassign and appears in the Name field on the Auto EDID test results screen. The following is an example ofthe text file:
