Apple 4K tv and LG oled signal issue

Hi there, I have seen others report this, when my Apple TV is playing it seems to switch to a black screen and displays no signal. Seems to be worse on YouTube when switching between ads and back to videos and also when launching content on Netflix once the app opens.

To be clear this isn’t a wifi, cable or signal issue, there seems to be some issue with ATV and a lag to the signal to the LG particularly when showing Dolby vision content.

Changing ATV settings to SDR reduces how often this happens but this isn’t acceptable for such a premium device.

Anyone else experiencing this?
