Ps4 screen flashing black screen every few seconds?

Disabled deep colour and only thing that fixes it is to set 1080i over 1080p.

Thing is though I can't see any picture quality loss at 1080i but keep reading it's meant to be terrible?

I had my PS4 losing signal to my TVs randomly. Turned out the HDMI cable was faulty.
