The J6300 LED TV is Samsung's top-of-the-line 1080p TV in 2015. It has good picture quality, handles motion well and has a lot of features, but it isn't perfect. The colors change when viewed at wide angles.
Unfortunately, Samsung doesn't sell top-quality 1080p TVs anymore. The J6300 is a good mid-range TV, but it is not high-end. It has average input lag and motion blur, which isn't ideal for gaming. The screen uniformity is also sub-par. Picture quality-wise, this TV is about the same as last year's H6350.
The contrast ratio is good, but not exceptional.
The J6300 isn't ideal when watching at an angle because the colors desaturate.
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.
It doesn't reflect much. However, you can see a small rainbow around bright objects. The screen finish is semi-gloss, which is inferior to what Samsung uses on higher-end models.
It can get bright enough for most situations, so do not worry if you have a few windows.
There is no judder when a movie is playing via a 24p source (like Blu-ray player). Over 60p or 60i though, it doesn't always succeed at removing the 3:2 pulldown. You can turn on the soap opera effect though to get rid of it.
Labeling the input as PC is the way to get the lowest input lag on the Samsung J6300. Game mode is a bit higher, at 50.1 ms.
Set the HDMI type to PC to benefit from chroma 4:4:4.
Decent low-end and loudness for a TV. The frequency response is decent, except that it suffers as the volume increases. There will be pumping present when the TV is under heavy load.
Major Apps Available
The Tizen smart platform has developed quite a bit over the year, and is now quite good.
The remote included with this TV is just a basic one. If you want Samsung's smart remote, you'll need to get the Samsung JU7100 instead.
