This tv has been discontinued.
It was replaced by the LG LF5600

The LG LB5600 LED TV is not a good value. The picture quality in both a dark and a bright room is sub-par, even compared to TVs in its low price range.

  • Great color accuracy at an angle.
  • Low contrast ratio. In a dark room, the blacks are gray.
  • It reflects a lot of light. The picture in a bright room gets washed out by the reflections.
  • Very low input lag. However, it suffers from a little bit of inverse ghosting with fast-moving objects, so it isn't ideal for gaming.

LG LB5600 Design

The LG LB5600 LED TV has the same design as all LG TVs in the 5 series. The borders are matte gray and the TV is slightly thicker than average.

LG LB5600 Stand

The stand is a big problem with the 2014 LG TVs. It is stable, but it is as wide as the TV itself. You will need a wide table, even for the 42".

Black : 0.125 cd/m2
White : 100.5 cd/m2
Contrast : 804 : 1

In a dark room, the LG LB5600 LED TV isn't great. The contrast ratio is low, which causes dark scenes to appear dull.

8.0 Black Uniformity
LG LB5600 Black Uniformity

The black uniformity isn't bad, but because the blacks are gray, any small issue is more apparent.

5.0 Gray Uniformity
LG LB5600 Gray Uniformity

All IPS panels in the low and mid level price range seem to suffer from a significant dirty screen effect. You won't see it under normal footage, but it could bother you with sports or panning shots.

7.3 Viewing Angle
Viewing Angle : 32 °

The viewing angle is excellent for an LED TV. When watching from the side, you won't suffer from a significant loss of picture quality the way you might with most other LED TVs.

7.0 Average Room
LG LB5600 Average Room
Reflection : 2.5 %
Surface Type : Semi-gloss

The LG LB5600 reflects a lot of light. Even a normal room with a few lights causes issues with this TV. The semi-gloss screens of other brands perform a lot better.

7.4 Bright Room

Max white : 237.8 cd/m2

Don't buy this TV for a room full of windows. You will see virtually nothing. It doesn't get very bright and the TV has a yellow tint under bright conditions.

7.5 Motion Blur
LG LB5600 Motion Blur

This TV has effective backlight flickering, but the motion blur trail is longer than average. It has slight inverse ghosting; the trail appears brighter than the moving object. Is you watch sports or play video games, you will prefer another TV.

The picture quality of the LG LB5600 LED is inferior even to other entry level TVs. It reflects a lot of light and has a low contrast ratio. If you are looking for a budget TV, go for the Vizio E Series or the Sony W600B instead.

Questions & Answers

Does it support movies (from flashdrive) with DTS audio?
It can't read movie files at all.
Does the 39" have an IPS panel? I read the review of the 39" on and that size got very good results for contrast and black levels, and mediocre viewing angles.
No, it doesn't. There are no 39" IPS panels on the market, which explains the results of the review you read.
I want to know how to put the TV in 1080p, please. Thanks.
Your TV will display 1080p by default. If you're not getting full quality from the resolution, it will be because your source is not sending a 1080p signal.
Does it support HDMI ARC?
I have a movie in six different formats: Mkv, avi, divx, wmv, etc, etc. The LG 42LB5600 will not recognize any of them. My VIZIO 55in 4k reads every one on the same USB flash drive. It is a 2.0 16GB drive, which is recommended. Desperately seeking answers as to why it doesn't work.
Your LG TV can't read video files, so you'll need to connect a different device that can. A PC running the VLC media player will be able to handle just about any media file, so your best bet would be to connect one to your TV via HDMI and use that.
Does it have a game mode?
Yes, but every mode has the same low input lag, so you can use any of them.
We have a Vizio Blu-Ray player that won't work when plugged into the HDMI port. Is there a possible compatibility issue? Other ideas?
Compatibility should not be a problem. Make sure you selected the corresponding HDMI Input number on the TV. Also, your Blu-ray player might output on another connection. Check the manual for the player to troubleshoot it.
Why does the volume mute when I change channels? I have to turn power off and back on to get the sound to come back on.
This is not normal. Call LG.
Hello, I just got the 42lb5600 and I'm very pleased with the price and quality, but I just found out that some stores are selling the 49lb5550 for about the same price I paid for the former. Now I'm thinking about maybe getting the 49" because I'll be gaining 7", but I'm worried about the input lag and the sound! Any suggestions, please?
We didn't review the LB5550, so unfortunately we can't offer a direct comparison for input lag, and we did not test for sound with last year's TVs. It's likely that the TV would have similar input lag to the other LG models, though, so it's probably somewhere between 27 and 45 msecs.
Can you play music off your phone through the TV?
Yes, but not wirelessly. You would need a cable that could either connect your phone to HDMI or to the audio input.
We are not taking any more questions for this product because we no longer have it in our lab.
