The Samsung J5500 LED TV is a good basic 60Hz TV. While it does have a good smart TV interface, it lacks more advanced features like motion interpolation or 24p playback. The picture quality is good in both dark and bright rooms, but it has quite a lot of motion blur.
The Samsung J5500 has the same stand as the pricier J6300. It is stable, but a bit wide.
The colors on the J5500 change as soon as you are at an angle. You can still see the picture, but it won't be as good.
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 semi-gloss finish on this Samsung doesn't reflect a lot of light. You will have no problem having a few lights on.
The maximum luminosity of the screen is average, so while it isn't the best choice for a porch or sunroom, it should be fine in a room with a few windows.
Game Mode on this Samsung brings the input lag to 40 ms. PC mode is barely higher, at 41.9 ms. Movie mode has 91.7 ms of lag.
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.
