So far problem has not come back.
Update : Well today it came back again. I turned off the system and held the power button for 10 secs and turned it back on and it stopped it again. This tells me it’s not the monitor now at least. It’s the system for sure. My new system will be here by Saturday. But this will be yet another first system bad experience. Every single xbox at launch I have purchased I’ve had to exchange the first system for another one.
