Update to tv saga,I returned tv for replacement as I wasn't happy. However I wasn't very lucky in the panel lottery as the replacement tv has similar if not more banding issues but these are to a lesser degree so decided to keep tv ( took 3 weeks to get a replacement).Anyways as for picture quality issues previously mentioned when watching dvds and sd content it seems there's dvds and there's dvds. Some look terrible and some look very good,any Star Wars DVDs look very good . Same as tv channels,some look decent,others terrible which obviously excludes any blame to the tv.On 4k streaming via Netflix picture looks great so obviously its all to do with the quality of the feed tv is given. My only remaining issue is,what should I choose to do upscaling? I have a panny blu ray and a sony av which can upscale to 4k or should I leave it to the tv to do it all? Thanks for any replies.
