This is a great tv. Upscaling is very good. Got 65" didn't have room for 78". Don't bother buying a 4k blu ray or receiver right now b/c drm compatible ones aren't out yet. Optical audio out is through one connect box not back of tv like specs say so use that to send audio back to your receiver. Matrix surround I'm sure isn't perfect but has sounded great to me and I'm a tech professional and a musician. People are saying curve is a gimmick. The place I've found it compelling is when watching 3d it really adds depth at the edges. I'm using the built in 3d function for normal tv which is quite nice as this technology has matured in this tv. 3d glasses don't fold which is dumb but you can snap sides off for storage. No app for Amazon prime which is ridiculous but hopefully they'll figure it out in firmware update. Don't bother with third party remote apps for your phone or tablet as Samsung broke those with this series via encrypted protocol. Samsung smart view 2 is your option.
I would recommend this TV to anyone...Its very pricey but well worth it. Its the last TV you will have to buy for a very,very.very long time. The picture is exceptional and the sound quality is great...The UHD is out of this world
Over the last 7 years I have purchase 2 x Plasma's and 1 X Led LCD TV from a respected Japanese competitor in my search for the best picture quality (all top end TV's). This Samsung TV has amazed me. I have never been as satisfied with a TV's picture quality and after running a simple calibration test, a couple of minor changes, the picture was even better. Pros Picture quality, Realistic colour, TV remote , TV setup . Foxtel picture even good in Standard def. Cons Not sure about the curved screen, A massive e manual.
