The LG UF7600 4k LED TV has great smart TV features, but the picture quality both in a dark and a bright room isn't very good. It has the worst contrast ratio that we have measured so far, and it reflects a lot of light.
Picture quality-wise, the LG UF7600's main positive is the color accuracy at an angle. You will have the same picture quality when you view it from the side as you get in the 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.
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.
