LG LN5400 LED TV Review

Reviewed Jul 10, 2013 By Cedric Demers
This television has been discontinued.
It was replaced by the LG LB5800

The LG LN5400 LED TV has a good viewing angle and low input lag. However, its contrast is very low and it suffers from some noticeable motion blur. This TV is more suitable for a bright room due to its poor blacks.

7.4
Overall
  • Very good viewing angle. The colors stay true wherever you sit.
  • Low input lag. It is great for a gaming TV.
  • Average amount of motion blur.
  • Only 2 HDMI inputs.
  • Poor contrast ratio. The blacks will appear gray when you have the lights off. This isn't an issue in a bright room.

Dark Room

Black: 0.132 cd/m2
White: 102 cd/m2
Contrast: 773 : 1

The LN5400 does not perform well in a dark room. The blacks are gray due to the poor contrast. If you want an LED TV for a dark room, you will be better served by a Samsung like the F5500.

Viewing angle: 37 °

This is the LN5400 strongest point. The colors stays about the same at any angle. We measured a drop of half the contrast at 37°, which is really good for an LED. This makes the LN5400 a great choice for a living room with multiple seats.

LG LN5400 Uniformity

The backlight uniformity is average for an LED.

Bright Room

Reflection: 3.4 %

It performs a lot better in a bright room where you can't notice its poor blacks. The reflection is slightly more than average for an LED.

Max white: 212 cd/m2

The brighter the scene, the better it performs.

Video Games

Like most LG TVs, there is slightly more blur than average. Most people won't notice it though.
It supports 24p playback for movies. It doesn't have motion interpolation (the soap opera effect).

Conclusion

If you don't have a dark room, buy this TV. Its only major downside is its poor blacks when you have the lights closed. With the lights on, it is a solid TV with an impressive viewing angle. It also has a very low input lag which is perfect for gaming. It is also significantly cheaper than the competition.
