Flickering and weird Noises (From the Speaker?) when having HDMI Sync Issues

[SchmuFoo]

@IvoGrijt

Does this flickering happen when:

1. You connect the Philips Hue HDMI Sync Box to any other device?
2. You connect any other device with HDMI Output to the PPM?

I’m using a HDMI-over-CAT Extender Setup and the problem only occours, when the Hue HDMI Box is sitting in the middle before of the Transmitter and Receiver. When connecting my Equipment (via AV-R) directly to the PPM, or when I directly connect a FireTV 4K to the PPM, then everything is fine.

But good point, I will test if the problem also occours when using a (Philips) TV instead of the (Philips) PPM.

3. Can you change the cable you’re using to connect the Philips Hue HDMI Sync Box to the PPM?

I tested it with different other cables and also today I’m receiving even more brand new HDMI Cables for testing.
