TV cuts out and starts back up, with Sync Box
Sorry for the messy title
The situation is this. I‘m watching stuff on my Apple TV 4K, which feeds into the Hue Sync Box which then feeds into the LG TV. Sometimes not at all and sometimes 1-2 times within an evening the screen just turns black. Then the HDR Symbol appears at the top right, until the Image comes back. All taking like 5-15s. Whatever was playing usually stops playing, but i can just start playing again.
It‘s sounds like a small nuissance, but when really immersed in the movie or series it just knocks you out of it.
Does anyone know what causes this? Or had the same issue?
