Aha, so you’re showing off some later firmware 🙂
I did a factory reset last night to get the latest firmware. It shows 4.17 for the build version, which is correct.
Software version? DCX960_-MON-PRD-00.01-067-AQ-AL-20190628143437-NA004
That looks ok, as it’s the production firmware from 28th June.
I’m currently doing some testing to see if it’s an HDMI handshaking issue, by turning the devices on in different orders to see if that helps.
Edit: Nope, can’t get it to show. Turning the box on turns on my TV and AVR automatically (and it’s not IR, it’s definitely HDMI-CEC). Also, if they are both already turned on, the TV detects the HDMI-CEC input correctly.
