“Just bought the M 55". Got it all set up and added the sound bar the next day. When I turn the tv on I don't get a full screen and the resolution is only 480. If I wait a few minutes, turn it off and then back on, the picture is fine. Why?”

• Make sure you’re using latest HDMI 2.0 for better audio video quality and have faster internet as well.
