Good morning guys,
I can report that I am having exactly the same issues, While on the menu / playing a game the screen will drop out and go black for a few seconds! I thought this was an isolated issue due to Sony's response... This is my first PS4 console and it's putting me off playing!
I can confirm my setup below:
Samsung UE65KS8000 (UK) with PS4 Pro connected into the One box,
Samsung firmware 1154
PS4 Pro 4.06
I have tried 2x HDMI Cables which I though helped but didn't, Changing to YUV Setting helps a lot but still receiving drop outs randomly
I will try bypassing the One box tonight and plug straight into the TV!
Hopefully we can get a resolution soon!
