Hi @Graham71 yes, you should be able to change this. certainly can on my Tv though that is an older model. Go to sources. where it says Sky press up on Smart Remote and click on Edit. You will see all the Device icons,press right and you can change the names. see more here: https://www.samsung.com/in/support/tv-audio-video/how-to-label-the-inputs-on-your-samsung-f-series-t...
