Thank you for the suggestion, I will give it a try when I get home. I think there is only a firestick connected, I will also try in a different HDMI socket.

Have an LG55Nano which works well apart from when on specific BBC shows whereby whenever there is a switch if camera, say from contestants to host and vice versa, there is an extremely annoying flickering motion that takes place. May sound petty but any visitors comment on how distracting it can be. Happens constantly on Richard Osmans House of Games, Impossible, Pointless and similar BBC programmes. Reported it but was told I had to get video clips for them to assist despite it being less than a year old. Life's too short. Any advice very welcome.
