Hi,

In Xavier AGX there are three HDMI ports but only one CEC line. Can we just short the CEC lines from 2 HDMI ports after the CEC gating circuitry or should we buffer the signals? Will that work. Is it possible for 2 separate ports to share the HDMI CEC

Hi,

From hardware aspect, only one HDMI port supports CEC.

But from software, we don’t have a tool
