Running an HDCP 2.2 Sink test
The procedures below describe how to run the HDCP 2.2 authentication on a DP 1.4 sink device. For testing
DisplayPort display devices (sinks), the 980 DP 1.4 Video Generator / Analyzer module emulates an HDCP
2.2-capable DisplayPort source device. You can either verify the simple case with the module acting as a source to
test a display or you can test the input of an HDCP 2.2-capable DisplayPort repeater device to verify its handling of
downstream display devices. You can optionally view the HDCP 2.2 authentication transactions over the DDC
using the Auxiliary Channel Analyzer (ACA) utility. Procedures for monitoring the HDCP 2.2 transactions through
the ACA are in the next section.
To run the HDCP 2.2 authentication test on a sink:
1. Connect the DP sink device to the DP module's Tx Analyzer port 2 as shown below.
Note the second PC shown is used for the external 980 GUI Manager application. In this case you will use the
embedded 980 GUI Manager application on the 980 Test Platform.
