This tv was replaced by the LG LF6000

The LG LB5900 LED TV is an affordable barebones TV. Unfortunately, the picture quality isn't as good that of other TVs, especially in a dark room. You will be better off with another TV.

  • Great viewing angle. The colors are great, even when viewed from the side.
  • It has a fair amount of motion blur, however, making it average for video games.
  • Very low contrast ratio. In a dark environment, the blacks are gray.
  • Wide stand. You need a very wide table to support it.

LG LB5900 Design

The design of the LG LB5900 is very similar to other LG TVs. Same borders and thickness.

LG LB5900 Stand

The stand is very wide. The 47" LB5900 barely fits our 38" table.

4k : No
6.1 Contrast
LG LB5900 Contrast
Black : 0.118 cd/m2
White : 100.2 cd/m2
Contrast : 849 : 1

This TV has an IPS panel, which means the contrast ratio is very low. It doesn't matter in a bright room, but the blacks will appear gray if you watch TV at night.

8.0 Black Uniformity
LG LB5900 Black Uniformity

The black uniformity is average. The poor blacks accentuate the uniformity issues a bit, but there is no significant clouding or flashlighting.

5.0 Gray Uniformity
LG LB5900 Gray Uniformity

The LB5900 LED TV has a lot of gray uniformity issues. The edges are darker than the rest and it has a lot of darker spots everywhere. This isn't an issue with normal footage, but if you watch a scene with a solid color (like in sports or a panning shot), you will see the dirty screen effect.

7.3 Viewing Angle
Viewing Angle : 32 °

This TV's viewing angle is great. Even if you are watching TV at an angle, the colors are excellent. The screen just darkens off-axis instead of losing saturation like most other LED TVs would.

8.5 Average Room
LG LB5900 Average Room
Reflection : 1.8 %
Surface Type : Semi-gloss

At least it reflects less light than the similar LB5800. The screen is more visible when you have a light on.

6.5 Bright Room
LG LB5900 Bright Room
Max white : 176.3 cd/m2

The LG LB5900 does not get very bright. Enough that a few lights in the room will not ruin the picture, but still not optimal for a room full of windows.

Score components:
7.0 Motion Blur
LG LB5900 Motion Blur

This TV has a rare artifact on fast moving objects called inverse ghosting. It overvolts the pixels with the goal of reducing the ghosting, but it results in an opposite white trail. This isn't good for fast moving footage like video games or sports.

Motion Interpolation
Motion Interpolation : N/A


Score components:

LG LB5900 Input Lag
Input Lag : 29.8 ms

This TV's input lag is very low. You won't notice it, even in fast video games.

Though it is affordable, the LG LB5900 LED TV is not a great value for the price. The picture quality, especially in a dark room, is not as good as other TVs in its price range. The Vizio E Series is a better alternative for a barebones TV.
