No, but with it being the tv in the main sitting room I cant be always changing it between HD and UHD, so I just leave it on the HD on sky q, as there's not much UHD being aired atm.. But I just think its kind of bad if you have a 4k tv and have it setup in 4k, but the non 4k content looking noticably worse then in the non 4k setting.. I wonder when 4k becomes the standard in a few years will the quality of 1080p and lower content improve when tvs are set to 4k,, I noticed this a few years ago bewteen 720p and 1080p, that 1080p didn't look as sharp and good as 720pHave you tried the "IMAX Enhanced" stuff on Disney+ or anything on Apple TV?
I thinks its Samsung AU7100 55 InchWhat model TV is it?
