TV flickers sometimes
I have apple tv4k, connected to Samsung TV by HDMI cable . sometimes screen flickers, goes black and sound is lost for 10-20 secs. problem appears even in home screen, not only while playing.
cable is high quality, WiFi connection is stable and fast, distance to router from tv is 10 meters.
tvOS is latest.
any suggestions?
