This tv has been discontinued.
It 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.

Pros
  • Great viewing angle. The colors are great, even when viewed from the side.
Cons
  • 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.

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.

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.

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.

Just wanted to confirm that the LG 60LB5900 that I purchased was definitely not the same pixel layout described in this article. I can also confirm that the input delay is nowhere near the 29ms stated in the article, but is in fact closer to 100ms in PC (HDMI)/Game (Picture setting). Pixel layout: (rtings.com picture on the far left, and crops of my TV on the right.) i.imgur.com/bRFfv5t.jpg Input lag test with 1/2000 shutter speed on a DSLR: www.youtube.com/watch?v=n1GYNki0zo8 I just felt it was important to share this information as I used this website to make my decision on which TV to get, and clearly I'm a loser playing panel roulette with LG.
Thanks for sharing this. It is very interesting to learn that the 60" isn't IPS but VA instead. We will update our pages. As for the input lag, can you try the settings that we posted? We didn't do the PC/Game label trick on that one. The 29.8ms that we measured using the Leo Bodnar's tool was simply under Expert1 mode. Also, can you check if your set has the TruMotion feature that ours was lacking? And if it does have it, can you check to see if it indeed works correctly? Thanks!

LG's LB5900 is a 120hz and 240MCI configured TV. This article has incorrect values displayed. I think they mistook or duplicated it with LG's LB5800.
As mentioned in our review, our 47LB5900 didn't have the TruMotion feature (check the screenshot of the picture settings that we took). This means it couldn't interpolate the frames, so it behaved like a normal 60Hz TV instead. The LB5800 that we tested did have that feature, but not our LB5900.

Is it normal to have poor image clarity with an HDMI input from a PC? Trying to read letters on the screen seems to be blurry and hard to read. I had the kdl55w700b before the LG lb5900 and the image quality was fantastic, but the TV had severe clouding in the center during dark scenes. Is this normal? I think I might go back to the Sony after seeing the LG.
No this isn't normal. Have you tried our posted calibration settings? Also, make sure your PC outputs at 1080p.

Thank you for your accurate review. I returned the LG LB5900 for the Samsung H6203. The Samsung picture quality is much better. The difference was immediately noticeable right out of the box. At Best Buy the prices were $850 and $899, respectively. While the LG was less expensive, it has no connectivity. I hoped that LG traded off net access for a better picture... they didn't. The net component of this Samsung isn't the greatest, but except for the full web browser, quite usable. I like the "screen mirroring" and the remote TV diagnoses functions. Again much appreciation and keep up the good work.
Thanks for sharing your opinion on these TVs.

I was wondering if the 50" variant has a different panel than the 47"? It seems other sites have given the 50" model glowing reviews, along with great black levels and contrast. Thanks in advance.
It could be. LG does produce 50" IPS panels, but with the lower-end models they often put VA panels in them instead.

I would love it if you could do a review of the LG UB9200 or UB9500. I am very interested in this set but fear the black levels and contrast ratio will not be up to par. Do you have any insight on this TV?
We probably won't have time for them. They are IPS though, which means their contrast ratio will be in the 1,000 : 1 range. Poor blacks are common to all IPS panels, unfortunately.

I was wondering if it's possible to use an LG magic remote for this TV. I have a magic remote and it can't change inputs for some reason, but it can change channels and volume and turn on the TV.
It is not fully compatible; some buttons won't work.

The TV I have came with what appears to be an A-MVA screen. I went and looked at a display model at another local retailer and it appeared to have an IPS screen.
Which size? And do you base your assumption of the LCD technology on the shape of the pixels? If that really is the case, it wouldn't be the first time a manufacturer uses different panels in the same model. It could also be why LG doesn't list the LB5900 as IPS on their website, so they can change it at their own discretion.
I have a 50" and yes I took a picture of the pixels on the TV I have and the display model. The display model I looked at has chevron (typical LG IPS) pixels. And the one I have is rectangle. In any case I have zero complaints as the quality of the picture is excellent.
Thanks for letting us know!

I have the LG 60 inch model. It has fantastic picture. Sports, including hockey, are amazing. I returned a Sharp 650 series because it was terrible all around. I also own a Samsung 7150 TV and nothing compares, but this LG holds its own.
Thanks for sharing!

I recently purchased a 50" LG LB6000 set from microcenter. I believe this is the same exact set as the 5900. It also was advertised on the box as being 120hz, but it's definitely 60 hz because it also lacks the interpolation feature. I am highly disappointed with my purchase and after two weeks I realize I can't live with the dirty screen/gray uniformity issue. I watch a lot of sports and the shadows bother me a lot. Soccer, football, and especially hockey just bring out this TV's faults. I'm looking for an entry-level set to replace it with, something that would perform much better for my needs and at a similar price. I'm torn between the Sony w600b 48", because it's direct lit, and the Samsung f5300 plasma. I think I should go with the plasma. What do you guys recommend? Thank you for the work you guys do. I appreciate your reviews.
If you have a dark room, get the plasma. Otherwise, the W600B is good.

After reading your review, I'm confused. Was it just your model that you reviewed that lacked the TruMotion feature, or do all of the TVs in the LB 5900 lineup lack it? I noticed they are advertised as 120hz, with their 5550 line advertised as 60hz.
Our 47" didn't, but some other sizes do have it.

I recently purchased the 50LB5900 through Dell at $499 and also includes a $125 gift card. However, I am slightly disappointing in the TV. Dark scenes are hard to make out and you can definitely see the splotches in the uniformity. We have the TV up high on a mantle. Do you think the viewing angle has anything to do with that? I am concerned about how this TV will look for football games and sports in general. Will the blur be pretty noticeable? Because I got a good deal with the gift card, returning it for something else is a tough decision.
We experienced similar uniformity issues with our LB5900, so it's unlikely that the viewing angle is the cause. Also, this TV does have reverse-ghosting issues with motion blur, so it's not going to look great when displaying sports.
Your best bet here is to try it out for a bit and see how it handles itself with your regular viewing activity. You can then decide whether you like it, or if you want to return it. Just make sure you make up your mind before the return window closes.

I recently bought the 55LB5900 and am disappointed in how blurry motion is, considering it's listed as a 120Hz TV. I'm thinking about exchanging it for a Vizio M5021-b1, as it's listed as a 240Hz. (The sales associate at Best Buy recommended the M series over the E series for Vizio, saying that the M series uses the same components as Sony and Sharp, whereas the E series uses lower-quality components.) What do you recommend?
Refresh rate doesn't matter when it comes to motion blur - the two are separate things. What's more, the advertised refresh rate is false, and the real one is usually much lower. The Vizio M should still be good for blur, though, so you should go for it.
We are not taking any more questions for this product because we no longer have it in our lab.
