HDMI 1.4/2.0 RX subsystem v3.1 - Why does HDCP fail authentication with Roku Express?

描述

When I use the 2019 model of the Roku Express (3930R) to connect to a HDMI RX Subsystem, only HDCP 1.4 mode works.

Authentication fails in HDCP 2.2 mode or if both are selected.

How can I resolve this problem?

解决方案

This is a known issue when the Roku Express is driven to HDMI RX.

HDCP authentication works without issues with the Roku Ultra and QD980.

To work around this issue, see (Xilinx Answer 76159)
