This tv has been discontinued.
It was replaced by the LG LF6300

The LG LB6300 LED TV has the best smart TV OS, low input lag, and a great viewing angle. Unfortunately, it has low contrast and reflects a lot of light, so its picture quality isn't up to par to TVs in its price range.

  • Great Smart TV interface. The WebOS platform is visually appealing and user friendly.
  • Low input lag, which is great for gaming.
  • Poor contrast ratio. The blacks are gray in a dimly lit room.
  • The screen reflects a lot of light. The screen becomes yellow when you have too much light in your room.

LG LB6300 Design

The LG LB6300 has a design very similar to the LB5800, except the back has the same gray finish as the borders.

LG LB6300 Stand

You need a wide table to accommodate this TV because the stand is as wide as the TV itself.

Questions & Answers

Is the LG 42lb6300 good for gaming? I just need a TV that is 120hz, full HD 1080p with low input lag. I'm gonna use it for my PS4. I need your advice. Thanks
It is a good gaming TV. The input lag is low (assuming you use the PC icon trick) and it handles motion very well.
Why does the LB6300 have an (MCI 600) rating, but the LB6100 has an (MCI 240) rating, even when they both have a 120Hz panel?
Marketing reasons, so that people purchase a pricier model.
What screen size did you review? I read on another site that the 50LB6300 (only) does not have an IPS screen.
We reviewed the 42", so the LG 42LB6300.
Does the LG LB6300 have a headphone jack? If not, does it come with an RCA output as an alternative for using headphone ?
No. If you want to use headphones, you need to have a DAC (digital to analog converter).
You should factor in the free 12-month Netflix subscription that is offered for the LB6300 (a $96 value) since most people have or will want Netflix. If you already have Netflix, it can be applied to an existing account for a $96 credit. The LB6300 is only $70 more than the LB5800. That means the thinner model with fancier WebOS smarts will come out to be cheaper than the lower LB5800 model.
Indeed, with the free 12 months of Netflix, you are better off buying the LB6300.
Do you think the LB5800 and LB6300 use the exact same IPS panels and so any measured differences are within the margin of error for your measurements and LG quality control? I am also wondering why the LB6300 is thinner than the LB5800 by 0.4" by your measurement, which is quite a lot. You said in the LB5800 review that it was direct LED lit. Does that also still apply for the LB6300, even though it's thinner? Is the lower input lag on the LB6300 compared to the LB5800 because of the faster processor? Oh, and one last question. How distracting are the reflections in a windowless bedroom with two fluorescent light bulbs up above? I am trying to decide between the 42LB6300 and 42LB5800, and that 0.4" slimmer body is making me wonder if there is something else going on with the LB6300.
It is definitely the same panel. The LB6300 is most likely edge lit. As for the input lag, it's probably not due to the faster processor. We achieved lower input lag by changing the icon of the input to PC, something that we didn't do on the LB5800 (not sure though if it is feasible on it due to the different interface). With no windows and only overhead lights, the reflections are not an issue. It is more problematic in a bright living room. For the 42", it is only a $70 price difference. If you plan on using the smart features a few times a week, the upgrade is worth it.
Trying to decide between the LG LB6300 and the Samsung H6350 (both 55 inches). The only purpose of this TV will be for gaming (PS4, XB1). The TV is in a windowless room, so it's never very bright.
If you don't need a wide viewing angle, the Samsung H6350 is better oin all other respects - especially in a dark room. The input lag is a little bit higher, but it isn't a deal breaker and it is barely noticeable.
I am planning to buy LG 55EC9300. If possible, please review this OLED TV.
We probably won't have time to review it this year. Maybe in 2015.
Do you know the maximum external hard drive size the 47lb6300 will play? For example, 2 terabytes or higher.
We haven't tested that, unfortunately. If you do end up with it, let us know the answer so we can update this question.
From some extra feedback on the LB6300; I had the 65 inch model but was frustrated with the power, composite, and digital audio inputs being inside the VESA mount points, which meant I couldn't access them when the TV was wall mounted. Also, the Skype app quit working when they pushed a firmware update and it wasn't compatible with my google nexus player on an HDMI port. Topping this all off was LG support blaming these problems on everyone else ended with me returning this TV.
Thanks for sharing your experience with it.
Thanks for including info about screen reflections. I have never found that in other reviews and it is critical.
It is indeed useful. Let us know if there are other aspects that would also be useful for us to test.
How's the 3D on the LG LB6500?
Unfortunately, we haven't tested the LB6500. It is passive 3D, though, which is usually great for 3D (half the vertical resolution for passive 3D is not really an issue).
Your reviews are really helpful! I'm choosing between the LG 47LB6300 (with the IPS) and Samsung's UN48H6350. My primary usage will be Netflix, Hulu Plus, and similar services. The TV will be located in a living room with big windows, but with blinds, so light can mostly be controlled. I found the Samsung at $600 for a limited time, and the LG for $700. What do you think will be a better choice?
Get the UN48H6350. It is not really a close call. Not only does it reflect less light, but it has far better contrast.
Does the LG lb6300 have flash player?
What's the difference between the 47lb6100 verses the 47lb6300?
The LB6100 doesn't have WebOS (it has the old interface), and it is only available at a few retailers.
What is the input lag when left in standard mode? I hate how PC mode makes the picture look bad on most TVs.
Unfortunately, we haven't measured it on this TV.
I am trying to chose between the 50LB6300 and the 47LB6300, I think the big difference is the IPS panel. Which one should I go for, or simply put, which one is the best option?
It depends on your room. IPS have better color accuracy at an angle, but a lower contrast ratio (gray blacks). So if you need a wide viewing angle, get the IPS.
I am deciding between the Samsung un55h7150 ang the LG 55ub8500. Is it worth giving up the 4k for 240hz and picture quality? Is the Samsung's picture quality better?
We didn't test that LG. The picture quality (besides the 4k), should be similar to the LG LB6300 that we tested because they both have IPS panels. Therefore, yes, the UN55H1750 has better picture quality, even if it isn't 4k. Especially in terms of contrast ratio.
How is the motion interpolation?
It works. That feature is similar on every TV. All of them have artifacts.
Will the 50inch version have better overall picture quality when facing the TV directly because of its lack of an IPS panel? What effect will it have, if any, on motion blur?
Yes, the contrast ratio should be three to five times higher. Motion blur should be slightly less. Viewing angle should be narrower.
Just as a heads up, some of the LB5800 models do come with an IPS display; it's just not advertised. I have the 47LB5800 and confirmed with LG that it does have an IPS panel.
Thanks for the info. Indeed, even the one that we reviewed was IPS (as you can see by the pixels picture). We will fix the table.
I am from Europe and I am interested in your opinion of the lb670. Is it expected that all series 6 LG LED TVs will have similar picture quality - black color, for example? I ordered the 50lb670 but i can cancel it and get the 50w805 Sony. It seems it's a choice between contrast and viewing angle.
Yes, the series 6 models should all have the same picture quality. Only the features change. Indeed, LED TVs can be categorized into two groups - one with great contrast but poor viewing angle, and vice versa.
Can you change the icon to PC for more than one input? Does that give you the lowest input lag for each input?
I’ve seen this TV with uneven backlighting on the side. The sides of the TV seems to be a little darker than the middle part. Is that normal for this model?
This defect is present on every LED TVs, to some degree. It varies per unit and it is more noticeable at an angle. If you can only see it on a completely black screen, don't worry about it. But if you can also notice it while watching normal footage, you might consider exchanging it for a new one.
I just got my 42lb6300 and it has very bad IPS glow when watched off-center. Why can't I see the glow in your viewing angle video?
The IPS glow is too subtle to be captured in our video under our conditions. The glow is more present at a vertical angle than an horizontal one, as well as when you are close to the TV (therefore increasing the vertical range). It would most likely appear if we would either have moved the camera vertically or if we would have used a completely black screen.
According to the manual, under Picture Options, there is a setting called "BLACK LEVEL: Compensates the screen brightness and contrast by adjusting the darkness of the screen." How effective is this at lowering the black level for darker scenes? Is it like with Samsung where it dims the whole backlight? How much does it dim? < 0.1cd/m2? Obviously on ANSI it's not going to dim, because the picture is too bright.
We did set that setting to Low (see our configuration settings). This is not local dimming and it does not affect the backlight in any way. This setting is simply a remapping of what is considered the black reference color, to accommodate your source. It changes the range from 16-256 to 0-256.
When will you review the LG 47LB5900?
Not soon; maybe in a few weeks. We have more popular models scheduled first (like some Vizio TVs). That said, the LB5900 has an IPS panel, so the picture quality will be really similar to the LB5800/LB6300 that we reviewed.
I want to buy an LG TV only because of the ease of use, magic remote, and WebOS. 42" to 50" for internet, movies, videos on internet only. Which LG should I buy?
Assuming you don't need 3D, get the LG 47LB6300. If you don't want an IPS panel, get the 50" version (the 50LB6300).
We're looking to use this TV for a digital signage application. Initially, we will use a "player" PC, however, we want to use the HTML5 built-in WebOS as a replacement for the player. Most of our use will be in portrait mode. Do you know if WebOS will recognize a rotation of the TV, or can it be set? Also, from an IPS panel perspective, are there any viewing angle issues in Portrait mode? BTW, despite our name, we are a USA-based company in the Chicago area.
Not sure about portrait mode on the LB6300, but for commercial use, you should look to their commercial line of WebOS TVs (the LS55A for example). They are, of course, pricier, but they are built to do exactly what you want (and do support the portrait orientation).
As for IPS panels used in portrait, it is a bit worse. The vertical viewing angle (when in landscape) is different from the horizontal viewing angle. Still better than VA panels, but there is something called 'IPS glow' that can be seen. It only affects the darker colors, so not something to worry about for digital signage (which usually displays bright pictures).
Your reviews are invaluable for a regular electronics consumer such as myself. One thing that would be helpful to me and that seems not to have been included in your analysis is the audio attributes of the TVs. For a number of reasons, I cannot add an elaborate sound system to augment the built-in speakers, so their quality is important to me. Nothing elaborate - just a basic evaluation would be very helpful in your coverage.
We will next year. For 2014 though, we wanted to concentrate on picture quality. Thanks for the feedback.
Does local dimming help with the 6700 series' black levels?
No. Local dimming on edge lit TVs is not effective at all.
Just reading that you "confirmed" the 5800 has the exact same panel as the 6300, so how is it that the 5800 is a 60Hz panel and the 6300 a 120Hz according to the panel info?
It depends what you mean by panel. The actual LCD layer is the same. The difference is the driving circuit. 120Hz panels have a MEMC (Motion Estimation / Motion Compensation) chip embedded to convert the 60Hz to 120Hz. The difference is just the circuit that commands the LCD layer.
I am looking to buy a large TV to use as a PC monitor. I will be watching it from eight feet away in a dark bedroom. I plan to watch movies on it and do a lot of gaming. I am accustomed to the quality of my outgoing plasma, and am therefore looking at an IPS because I've read it's the best looking LCD panel type. Am I wrong in thinking about going with this LB6300? The other contenders for me are the Sony W600B and Samsung UN48H6350. Which one is the best for my stated purpose? Thank you for your time.
IPS is not necessarily better - just different. The main advantage of IPS is its color accuracy at an angle. This is useful in a PC monitor if you sit close, because the color will be good even on the edges. However, IPS has a really big downside: it has really poor blacks. For typical TV usage, most people prefer the better blacks because the viewing angle doesn't matter. Therefore, for you, you will probably also want better blacks (assuming you sit in axis) because you are eight feet away, not at a normal PC monitor distance. Get the Samsung UN48H6350.
I just bought the LG lb6300 55 inch smart TV on 12/2/14. The screen is now showing a small black spot near the top of the screen. No idea what caused it or where it came from. Is this a common defect?
This is not common. Either return it if you are still within the return window, or call LG to get it replaced.
What DAC would be the best one to use with the LG 42LB6300 in order to convert its Optical Audio Out to 3.5mm Analog Audio for my Powered 2.1 Speaker System, while viewing ON-AIR TV and Netflix?
Unfortunately, we do not test DAC yet, so we cannot recommend you one.
LG 49UB8500. When do you plan on testing the LG UHD models? I am deciding between the Samsung UN50HU8550 vs LG 49UB8500. I saw both at Best Buy. They didn't look much different, but all reviews say to get the Samsung. However, I need a TV with a wide viewing angle and the LG has an IPS panel. What do you recommend?
2015 models. We won't have time for the 2014 LG UHD models. That said, if you need a wide viewing angle, get the LG 49UB8500. The IPS panel is worth it if you want good color accuracy at an angle. The reason all reviews point to the HU8550 is for the better blacks when sitting straight in front of the TV.
Any TV similar with this TV with 3D, but with better blacks?
What do you mean by similar? You can't an LED TV that has both a wide viewing angle and deep blacks. You need to compromise.
Why does my TV go from 120hz to 60hz?
The difference you're seeing is likely the input on your TV. When you change inputs, the hz number at the top of the screen is the source's output, not your TV's native refresh rate. The only difference 120 hz really offers is the ability to interpolate motion, which makes the picture look smoother.
You mentioned that the Samsung H6350 is better for gaming. Input lag aside, the VA panel in the 60" version is pretty bad for gaming. Reason I say this is with any textures that are high-contrast (chance N link fence, sunlit gravel, tree leaves, etc) flicker when the camera moves, or go dim until the camera stops moving. Regardless of settings (both game settings and TV settings), the issue never goes away. I never noticed this on my 2012 LG 47" that has an IPS panel I tried the Samsung H6350, the Vizio E series (60" with VA panel) and then a 65" LG with VA. All 3 of those have the same texture rendering issues when the camera moves. For videos, this issue comes up with and without interpolation, and regardless of settings. I tried everything. I know black levels can be important, but so is pixel response time. I've never had a problem with IPS in the past in this regard.
VA panels actually tend to have a lower response time than IPS panels, which translates into less motion blur / clearer moving images. For a proof of this, check out all our motion blur results.
Assuming good calibration settings, the issue that you are having could actually be the opposite: you are not used to a lower response time. High frequency textures (such as fences) create a flickering pattern not due to the screen, but aliasing on the console. This issue will be more apparent on a panel with low response time/motion blur because the picture won't be all blurred out.
Does the WiFi feature support hotspots? I'm using my phone and it's the hotspot.
Yes, that should be fine. You wouldn't be able to connect the TV directly to a data stick, but a WiFi hotspot is still a WiFi connection, so it should work.
Your thoughts on the LG 50LB6100, which does not have an IPS panel? How is this TV in a dark room?
Unfortunately, we did not review that TV, so we can't directly comment on its picture quality. It should have better contrast than the LB6300, meaning it should look better in a dark room. That said, it will have worse picture quality at wide angles.
Is the 47LB6300 bluetooth compatible and how can I use it with bluetooth headphones?
The LG LB6300 does not support Bluetooth connectivity for headphones.
We are not taking any more questions for this product because we no longer have it in our lab.
