The Samsung JS9000 SUHD 4k TV has excellent picture quality both in a dark and a bright room. If you don't mind the loss of color at an angle and it is within your budget, get this TV.
The Samsung JS9000 is our overall top rated TV this year. It has picture quality very similar to the cheaper JS8500, which is really great both in a dark and bright room. It outranked the JS8500 in our test suite, thanks to the lower input lag. If you don't care about the input lag, the curve, or the full OneConnect box, you get the same excellent picture quality with the cheaper JS8500.
The Samsung JS9000 is pretty eye-catching, thanks to its curved screen and gray back, and its stand is nice and stable. The bezel is not the thinnest, though.
While this TV did outperform all the others this year, the Sansungs JS8500 is a similar option that comes for a good deal cheaper. You pay a lot for a curved screen, so if that's not a 'must' for you, consider saving money with a flat TV.
The native contrast ratio of this TV is good. Turning on 'Smart LED' doesn't change the measurement on our checkboard pattern.
The edge-lit local dimming's zones are big, because the LEDs are located on the left and right sides of the TV.
The maximum luminosity of a 2% white window is not really impressive, even with 'Smart LED' set to 'High'.
As with the JS8500, the JS9000's edge-lighting backlight is really great at getting rid of the dirty screen effect (small darker patches). The top and bottom center edges are slightly darker, but it shouldn't be an issue.
The picture quality when you view at an angle is not as great as what you get from directly in front.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
Samsung's glossy finish is great at reducing the ambient reflections, and thus increasing the perceived contrast ratio when you have a few lights on. There is a little bit of rainbow glare around bright objects.
This TV can get very bright, but its glossy screen finish won't be ideal if you have windows directly opposite the TV. Your eyes will tend to focus on those outlines.
Movies don't have judder when using a 24p source (like a Blu-ray player). However, it doesn't always do the reverse 3:2 pulldown, so you might see a little bit of judder in movies when watching over a 60p or 60i source (like on cable, or some streaming boxes). Of course, turning on 'Auto Motion Plus' solves this, but it adds the soap opera effect.
In game mode, the input lag is very low (23.6 ms). In PC mode, the lag is a bit higher, at 55.8 ms.
It doesn't support an input of 1080p @ 120fps, but handles 4k @ 60 Hz @ 4:4:4 well. For 4:4:4, turn on UHD Color and use PC mode.
Major Apps Available
The remote is really good. It would be better if it came with more buttons - you have to use an onscreen keypad to input channels - but the motion and voice features are great ways to navigate quickly. The smart platform itself is likewise really good.
The One Connect box houses the processor and the inputs. Your TV won't be usable if it is not connected, and it's an unfortunate extra bit of clutter. Having this separate does mean, though, that you'll be able to upgrade some of the TV's 'guts' in the future, should you wish to do so.
