I had this last year and it always seemed to be an issue in winter with the heater on... once per 45 minute car ride it would give a NO SIGNAL and reset and be totally fine after.

Got the bmw update and lost all my coding and had to pay for that to be updated again

Now it's happened again... anyone else? 2016 550i

2016? Warranty?

If it was out of warranty I would be inclined to disassemble and physically reseat all of the connectors between the head unit and the screen. Hoping that it's a connection problem and not an internal component problem.
