I must start by saying that I think the T.V looks great off or on its got great looks and styled well the picture needs a few tweaks but on the whole the picture is sharp with good movement no ghosting on sports and from the limited 4K pictures I have put through the set well wow they are pin sharp with lots of detail so you might ask why the down beat title well let me start I have apple phones and ipads so I love ios operating system the tv starts to fall down when you use the smart functionalty I personally find the user interface slow and clunky come on android is this all you have to offer also it crashes when moving around menus and my biggest gripe after spending the money on this set at the moment it doesnt support 5:1 surround sound when watching either netflix or amazon prime I have a choice of watching through my ps4 with surround sound but only hd pics or watch through tv with great 4k but just stereo having spend a good 45 mins on line with netflix helpline I have found out they are now working with sony on a firmware update to solve this surely sony should have resolved this before the last update which incidently took 45 mins to download all in all like my title suggests a potentially great set mared by a clunky operating system and what seems to be half baked apps
