The LG LF5500 LED TV isn't a great budget TV. It has good color accuracy at an angle and low input lag, but its poor contrast ratio and screen uniformity are a deal breaker if you watch it in a dark room.
The LG LF5500 maintains good color accuracy even at an angle. The picture only gets darker when viewed from the side.
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.
In game mode, the input lag is a low 28.4ms. The other modes aren't much higher (31ms), so feel free to use whichever you prefer.
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.
