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.
Overall, the LG UF7600 is not a very good choice for a 4k TV, even considering the price. In a dark room, the blacks are gray, and the screen isn't uniform. In a bright room, it reflects a lot of light. The color accuracy at an angle is great though, as are the smart features.
The contrast ratio is incredibly low. The blacks look gray in most lighting situations.
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.
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.
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.
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.
To enable chroma 4:4:4, change the icon of the input to PC. For 4k @ 60Hz @ 4:4:4, turn on UHD Color.
LG's WebOS is a great platform that is easy to navigate and to use. You can read our full review of LG's smart features here.
