[Video] Image And Sound Drop Out (HDMI 2.0a Cable)

You can also try to switch OFF the Deep Color mode.
If you still have image or sound drop out, please check if your media player have the last firmware release installed. Press Blue button of the RC to check it.
If you have black screen problems with the supplied HDMI cable (even no booting "Z" logo), it may be defective. In this case, return it to your dealer so that it is exchanged by a new one.
