The LG LF6300 LED TV has great smart features and a wide viewing angle. However, it has too many downsides to be worth considering. It is only a 60Hz TV, it reflects a lot of light, it has a bit too much motion blur, and its input lag is high, too. Its contrast ratio is low, too.
It maintains good color accuracy even when viewed at an angle. Instead of the colors shifting, the picture just darkens.
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 lowest input lag we could get out of the LG LF6300 was 50.1 ms, under PC. Game mode had 69.7 ms.
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.
Poor frequency response, which gets worse as the volume increases. Significant pumping under heavy load. The TV doesn't get loud either, but the bass extension is OK for a TV.
