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.

Our Verdict

7.0 Mixed Usage

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

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

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.

Uniformity

The backlight uniformity is average for an LED.

Dark scene in a 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 better than average for an LED.

The brighter the scene, the better it performs.

Viewing angle
Viewing angle 37°

This is the LN5400's strongest point. The colors stay 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.

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).
