The Samsung J4000 LED TV isn't a very good budget TV. It has a good viewing angle, but the picture quality in other respects isn't great. It is also only a 720p TV, and lower-resolution footage isn't clear on it.
The contrast ratio isn't great. The blacks will look gray in dark rooms.
As of this review, the J4000 has the worst standard deviation of the gray color that we have measured so far. At least it doesn't have a lot of dirty screen effect.
The colors remain the same when you watch this TV at an angle, which is great.
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.
The center of the screen has very good black uniformity. However, there are a lot of brighter spots around the edges.
The Samsung J4000 lacks both white balance and colorspace calibration options.
It reflects an average amount of light. There are no rainbow around brighter objects, which is good.
The Samsung UN32J4000 doesn't get very bright, but it should be enough for a normal living room.
The Samsung J4000 handles motion very well, with almost no visible blur at all.
Game Mode doesn't make a significant difference on the input lag. All modes have about the same amount.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
The bass is practically non-existent with this TV. It doesn't get very loud and at higher volumes it will produce noticeable pumping. The frequency response is also not good.
This TV doesn't produce a lot of distortion, but it doesn't get very loud either.
