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.
Unless you really want a good viewing angle or WebOS, there are better TVs out there for the same price as the LG LF6300. In a bright room, it reflects too much light, and in a dark room, the blacks look gray. It is also not a good gaming TV, because of the high input lag and the sub-par motion blur.
This LG has an IPS panel, so it has the contrast ratio is sub-par.
The top and the side edges are much darker, and there is a significant amount of dirty screen effect.
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.
There is significant clouding on this TV.
The LG LF6300 reflects a lot of light. You can see a rainbow flare around bright objects.
It doesn't get very bright, which means it isn't ideal for a room full of windows.
The LG LF6300 has more motion blur than average.
This is a 60Hz TV with motion interpolation, so the effect won't be as strong. It does support 24p playback though, which is great for movies over Blu-rays. It can't do the reverse 3:2 pulldown though.
The lowest input lag we could get out of the LG LF6300 was 50.1 ms, under PC. Game mode had 69.7 ms.
To display Chroma 4:4:4, you need to change the icon of the input to PC.
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.
Low distortion levels throughout, but the TV doesn't get loud either.
The remote doubles as a mouse pointer, which works really well for navigating the smart features.
