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 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.
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.
