LG LN5700 LED TV Review

Reviewed Aug 02, 2013 By Cedric Demers
This television has been discontinued.
It was replaced by the LG LB5800

The LG LN5700 LED TV has the same screen as the LN5400, but is equipped with Smart TV features and motion interpolation. The viewing angle is great, but the contrast and black level is sub-par.

7.1
Overall
  • Great viewing angle for an LED TV.
  • Average amount of motion blur for an LED.
  • Average input lag. Most gamers will not notice it.
  • Low contrast. The blacks will appear slightly gray in a dimmed room.

Dark Room

Black: 0.140 cd/m2
White: 100.2 cd/m2
Contrast: 716 : 1

The contrast on the LN5700 isn't good, which results in grayish blacks. This TV isn't the best option in this price range for a dark room (the Samsung F5500 performs a lot better).

Viewing angle: 37 °

The viewing angle on the LN5700 is really good, without any discoloration. Half the maximum contrast was present at 37°.

LG LN5700 Uniformity

The uniformity is average for an LED.

Bright Room

Reflection: 3.3 %

The LN5700 is better suited for a bright room. The amount of glare is slightly higher than average, but it shouldn't bother you unless you have a lot of windows in your room.

Max white: 235 cd/m2

The details are more visible with a bright scene.

Video Games

The motion blur is slightly worse than the average LED.
It supports 24p playback without judder and it also has the option to turn on the soap opera effect.

5.9
LG LN5700 Input lag
Input lag: 66.6 ms

The input lag is more than the similar LN5400, but it shouldn't be noticed by the majority of gamers.

Conclusion

The LG LN5700 LED TV is basically the same as the cheaper LN5400, but with a smart TV interface. If you do not need this, save yourself some money and get the cheaper LN5400. Both have the same picture quality, which means they perform good in a bright room but not so much in a dark one.
