I have a Xbox One S and a Samsung KS8000 4K TV. Everything was working fine, but when i just upgraded and got a new receiver - the xbox now looses connection (goes black for a short time) or flashes white blocks on half the screen. Strangely this does't occur if I am playing a 4k game like Forza Horizon 3 or watching a 4K blu-ray. But on the xbox dashboard or in a game like overwatch it happens. Sometimes much more often then others but enough its no usable. But I didn't have this issue when going through the TV. Anyone have similar issues and suggestion on what can be done? Receiver works fine with PS4 Pro and Apple TV and other inputs.
