The LG LF6100 LED TV has great contrast and black uniformity, so it is a good TV for movies or TV shows. However, its motion blur and high input lag prevent it from being a good gaming TV.
Our Verdict
The LG LF6100 LED TV has about the same picture quality as the cheaper LF6000, but it adds motion interpolation (up to 60Hz) and smart features. The contrast ratio and black uniformity are great, but it has too much motion blur and high input lag. It is a good TV for movies and TV shows, though.

Test Results
You will need a wide table to accommodate this TV, because the stand has a foot on either end. Our 50" had a footprint of 40.5" x 10".
The LG LF6100 has a thin gray border around the screen which tends to stand out, rather than blending in with the room.
The native contrast ratio is really great - the best we've tested so far this year.
Unfortunately, the gray uniformity isn't as good as the black. The corners are darker and the screen has a few small dark patches all across the screen.
This LG has a VA panel, which means the color shifts when you watch the TV at an angle. The blacks are also not as great off-axis.
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 black uniformity is great on this TV. No clouding or flashlighting at all.
This TV has no problem upscaling DVDs. The picture stays sharp, even when 'Noise Reduction' is turned on.
The reflection on this LG LF6100 is average. You can have a few lights on without problem.
It doesn't get very bright, so it isn't the best TV if you have a lot of windows in your room.
The length of the motion blur trail is long. It isn't an issue for movies or TV shows, but it could be for sports or playing video games.
It is a 60Hz TV with motion interpolation. It also supports 24p playback (which means no judder in movies when sent over a 24Hz input). However, it cannot do a 3:2 reverse pulldown.
The input lag of the LG LF6100 is 49.7 ms under game mode. Labeling the input as PC increases the lag to 59.8 ms. The rest of the modes have a really high input lag 149.8 ms.
Label the input as PC to enable chroma 4:4:4.
This TV doesn't get loud, but the low-end cut off is decent. The frequency response is good at lower volumes, but it suffers as the volume increases. Pumping may be present.
Acceptable distortion level throughout the range, but the TV doesn't get loud.
The LG LF6100 is using LG's old smart TV OS from two years ago. It isn't user friendly, but it has all the apps that you need, and even a web browser.
