My issue is that every hour or so when playing my Xbox one X via the 4k HDMI input on my MU6470 the screen goes black for about 2 seconds then comes back to the xbox screen.
I thought at first it was due to ARC but I stopped using my sound bar this week as this is annoying. I did think my sound bar was sending a signal and the TV was changing source to that then returning to the xbox.
Last night the black screen bug happened about 3 times.
The TV was processing 4k and HDR 10 content from the Xbox.
Now I know that people are having green flashes when playing a console on the TV
I am wondering if this is down to that issue trying to be fixed.
I have unplugged all other HDMI wires when playing Xbox and still the black screen bug persists.
