12 Chapter 11 Testing EDID for HDMI
Testing EDID for HDMI compliance in display (sink) devices
The 882 supports the following EDID and video HDMI compliance tests in accordance
with the HDMI Compliance Test Specification 1.4 (CTS):
• Test ID 8-1: EDID Readable
• Test ID 8-2: EDID VESA Structure
• Test ID 8-3: CEA Timing Extension Structure
• Test ID 8-17: 861B Format Support Requirements
• Test ID 8-18: HDMI Format Support Requirements
• Test ID 8-19: Pixel Encoding Requirements
• Test ID 8-20: Video Format Timing
These tests are intended for in-house testing of products before submission to an HDMI
ATC for full certification testing.
Note: This feature is not supported on the 881 generator.
Testing HDMI sink device for EDID compliance
HDMI sink compliance testing is conducted through the 882’s HDMI OUT connector. A
standard HDMI-to-HDMI cable connects the device under test to the 882. The 882 must
be configured to output HDMI signals.
You can run the EDID compliance test on an HDMI sink device in three ways: 1) through
the front panel using the EDIDHDMI image, 2) using the EDID Compliance report also
available through the front panel or 3) using the Compliance Controller. The Compliance
Controller is an application (available in release 2.18 or later) that is available on the 882
web home page. This section includes procedures for running the EDID compliance test in
all of the three ways.
Defining the capabilities of the display device under test
After making the physical connections, you must specify the capabilities of the sink display
under test, which are based on the Capabilities Declaration Form (Appendix 3) of the
Compliance Test Specification. This enables the 882 to compare the expected results with
the actual results measured from the display.
The manner in which you define the CDF depends on which method you are using to run
the test (front panel or Compliance Controller). The following table provides a description
of the parameters in the EDID CDF that need to be defined. Use this table as a reference
when entering the CDF for any test regardless of the test method (i.e. front panel or
Compliance Controller). One key advantage of using the Compliance Controller to run the
