The LG UF7600 4k LED TV has great smart TV features, but the picture quality both in a dark and a bright room isn't very good. It has the worst contrast ratio that we have measured so far, and it reflects a lot of light.

5.3 Contrast

The contrast ratio is incredibly low. The blacks look gray in most lighting situations.

6.5 Reflections
Reflection
:
1.9 %
Screen Finish
:
Semi-gloss

Not only does it reflect a lot of light, very bright light sources also have rainbow glare around them.
For maximum luminosity, this TV is a bit below average. Not the best choice for a bright room.

5.6 Black Uniformity

The black uniformity is sub-par. The two lower corners are brighter than the rest of the screen.

The input lag is a bit high. We had to change the icon of the input to PC to lower it to 55.5 ms.

8.4 Motion Blur
Response Time
:
13.5 ms
Overshoot
:
2.9 ms

The response time of the pixels is constant across all transitions; motion blur won't appear worse in certain games compared to other ones. There is a little bit of overshoot, but it isn't very noticeable.

Picture quality-wise, the LG UF7600's main positive is the color accuracy at an angle. You will have the same picture quality when you view it from the side as you get in the front.

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.

6.1 Gray Uniformity
50% Std. Dev.
:
5.191 %
50% DSE
:
0.229 %

The gray uniformity is even worse. The edges are darker, and there are a few colored vertical bands that are a few inches wide.

Stand

The stand is separated into two feet placed at the opposite ends of the TV, so you will need a wide table. Our 49" spawned 43" by 9", which is exactly as wide as the TV itself.

8.0 480p Input

Upscaling of DVDs and 480p content looks good on this TV.

8.0 720p Input

Upscaling of cable TV and 720p content looks also good on this set.

8.5 1080p Input

1080p signals look a bit softer than on some other 4k TVs. You can see it in our motion blur pictures too.

10 4k Input

4k content looks good without any issues.

1.5 Local Dimming

The LG UF7600 is equipped with local dimming, but it is very slow to catch up to the picture, and the zones are really big.

The bass extension is decent for a TV, but the loudness and frequency response are poor. There will be noticeable pumping artifacts present when pushed.

This is a 60 Hz TV with motion interpolation. Unfortunately, there is a slight judder in movies when you don't want to turn on the soap opera effect.
