The LG LF5500 LED TV isn't a great budget TV. It has good color accuracy at an angle and low input lag, but its poor contrast ratio and screen uniformity are a deal breaker if you watch it in a dark room.

Our Verdict

5.9 Mixed Usage

While it has low input lag, the motion blur of the LG LF5500 is a bit too much to make it a good choice for gaming. Movies aren't great either, due to the low contrast ratio and poor screen uniformity. The main advantage of this LG TV is the good color accuracy at an angle.

Pros
  • Low input lag.
  • Good color accuracy at an angle.
Cons
  • Poor contrast ratio.
  • Significant motion blur.
  • Poor screen uniformity.

Like most LG TVs, the stand is separated into two feet, which requires a very wide table. Our 49" (LG 49LF5500) has a footprint of 40.5" by 10".

This LG TV's contrast ratio is below average, because it has an IPS panel. In a dark room, the blacks are gray, which isn't ideal.

It has the worst gray screen uniformities that we have seen so far. It has a lot of brighter spots, which creates noticeable dirty screen effect.

The LG LF5500 maintains good color accuracy even at an angle. The picture only gets darker when viewed from the side.

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.

The uniformity of the black color isn't great. The edges are darker, and our unit had a few clouding spots.

The LG LF5500 only reflects an average amount of light. However, there is a rainbow around very bright objects (like light bulbs).
Its maximum brightness is sub-par. It should be okay for a room with a window or two, but not more than that.

The LG LF5500 LED TV has a good deal of motion blur. It isn't a good choice for sports or video games, but it should do fine for TV shows or movies.

Very poor frequency response that only gets worse as the TV is pushed hard. This is the weakest TV we have tested in terms of loudness. However, the low-end cut off is decent.
