I am having the issue of the Fit to screen setting reverting back to Auto from On since firmware version 2001.4 on my QE50QN94A after turning the TV on and off using the remote, it does not happen all the time but enough for me to notice it.
I have heard from another owner on a different forum that this issue is also affecting their QN95A.
I too have the same problem with fit to screen and Samsung plus interfering when watching you tube and just now sky sports news. I’ve only had the tv since Saturday and was very satisfied until when I got home from work tonight and this started happening. I am also on latest firmware 2001.4 65qn94a model
