Which smartv did you get?
I got the 49" X830C, only because they had an 'open box' when I walked in to purchase the W800C (1080p) set for $700 as a hold over until OLED gets more players from Sony or Samsung to drive prices down in hopefully a year or two. I wanted a larger display for when UC4 hits (been gaming on a 1080p 27" IPS monitor for the PC/PS3/4).
But as the salesperson was heading to the back to get one, he noticed I was watching a PS4 stream on the X830C. He then said, "we have an open box, but the TV was never taken out, it was opened to give the guy screws for the base stand that his internet ordered one did not come with. We have let you have this for $600." (it retails for $900 and change).
It was a no brainer decision. 4K set, 120hz, X1 scaler, IPS (while not as deep blacks as VA, I am used to them from PC for better viewing angles), and perfect 4:4:4 Chroma 4K @ 60Hz for PC input, brand new for $600?, less than the 60hz 1080p set? Uh, YES! And they even discounted the extended warranty to be $40 less too. (Florida is the lightning capital of the world, while I never had an issue, better safe than sorry.)
I also lucked out, because I guess they gave him the stand brackets that screw to the TV and stand as well (the screw bag was taped to it), so I did not need the screws from Home Depot, they opened another box the next day and gave me the screws and brackets since it was mislabeled, and will correctly label the new open box so it isn't an endless cycle, lol.
All I got to say, Daredevil in 4K on Netflix... BRUHHHH!!!! (Just wish they did not have that silly noise filter, I get they wanted to add style, but the already crystal sharp bricks in the distance could be even sharper, lol) I will say though, make-up artists will have to be good as fuck going forward with 4K... you can spot all the imperfections and the makeup lines in the neck when not blended properly.
