The LG UF7700 4k LED TV has great smart features and good color accuracy at an angle. However, its picture quality when sitting in front is sub-par, both in dark and bright rooms. The contrast ratio is low, it has a few uniformity issues, and it reflects more light than average.

Our Verdict

6.6 Mixed Usage

The LG UF7700 isn't a great 4k TV. The picture quality both in a bright and dark room is not good. It also has high input lag and average motion blur for video games. In terms of positives, the smart features are great, and it has a great viewing angle.

This LG TV (except the 70") has an IPS panel. The contrast ratio is low, which results in poor blacks when you have the lights off.

It is equipped with the local dimming feature. The zones are really big, so as you can see in this video, it isn't very effective.

The main advantage of an IPS panel like the one found in this LG is the color accuracy at an angle. Instead of losing saturation, the picture just darkens when viewed 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 LG UF7700 reflects a lot of light. There are also a few rainbows around bright objects.
The maximum luminosity is average. Because the screen reflects a lot of light, that means this TV isn't ideal for a bright room.

This is a 120Hz TV with motion interpolation. It does support 24p playback for movies, and even do the 3:2 reverse pulldown over 60i, but it somehow couldn't do it over 60p.
