LG B6 OLED
It was replaced by the LG B7A
The 4k LG OLED B6 TV provides an excellent picture quality, with an infinite contrast ratio and great motion handling. It delivers great performance even when viewed from an angle, and is perfect for a home theatre setup. Unfortunately there is still room for improvement with an average full screen brightness and average input lag.
- Almost no motion blur in sports and video games
- Perfectly deep blacks provide an infinite contrast ratio
- Very good picture quality when viewed at an angle
- Brightness depends on screen content due to Automatic Backlight Limiter (ABL)
- Displaying static images results in temporary image retention
The LG OLED B6 has an impressive design with a very thin screen, metallic finished back and clear stand. Unlike the E6, there is no large sound bar but instead speakers built into the main body of the TV.
The stand has quite a small footprint but still feels very stable. It is made of clear plastic, similar to the EG9600.Footprint of the 55" TV stand: 22" x 8.7"
The max thickness is measured at the bottom half of the TV. From a side profile, it looks very similar to the E6. However unlike the E6, there is nothing protruding from the back and so the TV is thinner and appears more flush with the wall.

The LG B6P OLED panel's perfect black and high peak brightness of highlights results in a very good picture quality and HDR implementation, making the B6 a very good choice for a home theater enthusiast. The picture quality remains very good, even when viewed at an angle and reflections are dealt with very well. There is some temporary image retention, but this should not be an issue for most people. Those who like 3D will be a bit disappointed, since the B6 does not offer this option unlike the more expensive LG E6.
Like the other OLED panels, the light is emitted from the pixels themselves and are individually turned off when a true black picture is displayed. This is resulting in a infinite contrast ratio.
For reference, we took a video of our local dimming test.
The SDR peak brightness of the B6 is almost the same as the LG C6 and the LG E6. Overall SDR peak brightness is average, but for highlight smaller than 25%, it has good result around 400cd/m². Anything beyond 25% of the whole screen gets dimmed by the ABL (Automatic Brightness Limiter), and this affect the final score, making it an average performer when compare to any similar priced, LED TVs.
The peak brightness for the LG B6 is fairly good. It is quite similar in performance to the higher end LG E6. This level of brightness mixed with an infinite contrast ratio will make HDR content look amazing. Unfortunately the Automatic Brightness Limiter (ABL) causes the fullscreen brightness to be very low, and it may not be enough to combat glare in bright rooms.
Like the other OLED TVs tested before, the gray uniformity is better than LED TVs, but still isn't 100% perfect. On this picture you can see that the left and right side of the image are more bright and there is also a large band just right of the center that is a bit warmer. That said, the gray uniformity of the LG B6 is still very good and should not cause the dirty screen effect when watching sport like hockey or football. This may vary depending on the individual unit.
On the LG B6P, the image retention is still problematic. When an static image is present on screen for a long time, it will leave a imprint on screen until some normal video content is play. Usually after 5 or 10 mins, the faint ghost image should go away. Gamer should be aware of this inconvenient.
The viewing angle of the LG B6P is very good and you will have a relatively good picture even if you sit at a wide angle. You will notice a change in the tint when viewed from the side.
Since no light at all is produced by the individual pixel when a perfectly black picture is displayed, the black uniformity is flawless.
The LG B6P is using an 10 bit panel and color are reproduce very effectively. The gradation is very good and smooth, but there is still some little imperfection in the darker color, but should not be visible when watching movies or regular TV programs.
Even before calibration, the results are quite good.
The calibration is straightforward, and was able to fix the imperfections out of the box.
Wide color gamut is enabled automatically when the TV detects a HDR signal. The wide color gamut is about the same as the LG E6.
Update 10/13/2016: We remeasured the color gamut, and have updated the result.
The B6 has one of the best color volume performances of all 2016 models. It is able to cover most of the P3 color volume and produce saturated colors even at low luminance.
The LG B6 does have some image retention, but it differs a bit from what an IPS panel would show. Unlike LED TVs, on an OLED TV the image retention looks more like a photo negative, where the brightly exposed part of the screen now looks darker than the rest. When looking at the test picture of our 15% gray pattern the left part of the picture where the white section was is clearly darker than the right side which was black.
Even after 10 minutes, some faint retention remains, but this does go away after some more normal TV viewing. In a case where the retention lasts longer the LG OLED TVs do have some internal testing/fixing programs to fix retention problem and after running this program, any retention that would not be fixed by watching normal content usually goes away. We are not aware of any image retention being permanent on any OLED TVs that we have tested yet.
The screen coating on the B6P does a great job at dealing with reflections. It results in a purple tint as visible in the image, but this helps to reduce the intensity of the reflections.
Unlike the LG E6, the LG B6 does not support any type of 3D.
The B6 performs very well when it comes to motion handling. Fast plays appear well defined thanks to the excellent response time and it is possible to interpolate all content for those that like the soap opera effect. Movies played via a blu-ray or streaming apps are smooth, but for some other sources judder may be experienced.
As with other OLED TVs, the response time is excellent and so no trail can be seen following the logo. The backlight is flicker-free. Some people may prefer a flickering backlight instead. Motion blur is non-existent. For low frame rate content this lack of motion blur can be jarring, especially for panning scenes.
The B6 doesn't flicker, and there are no options to enable a flicker. This means that despite the fast response time, images may appear slightly blurrier than other TVs.
To play 24p source material without judder, you need to activate 'RealCinema' option under 'Setting'→'Picture options'. Although inconsistent, for 60p and 60i sources set 'Trumotion' to user and set 'De-Judder' and 'De-Blur' to 0 to remove judder. It wasn't consistent enough for us to consider a pass though.
The B6 is a native 120Hz display, and can interpolate 60Hz and 30Hz content. To enable motion interpolation, set 'Trumotion' to 'User'. For a 30fps source increase 'De-Judder' and for a 60fps source increase 'De-Blur'. Note that this may introduce artifacts.
The input lag is average but for casual gamers this should still be okay. The TV can accept a wide range of resolutions over all 4 of the HDMI inputs and displays text very clearly.
The 1080p input lag of the B6P is average and will disappoint the more professional gamers out there who need fast reflexes. To get the lowest input lag, set the input icon to 'Game Console' and change to the 'Game' picture mode. This results in 43.2 ms input lag with a 4k @ 60Hz input and 44.4ms input lag with a 1080p @ 60Hz input. With interpolation, there is 62.6 ms input lag.
It is important to note here that from the get-go, our set always had an input lag a bit higher than what other sources were reporting for this specific TV model, so some of this may be due to differences between individual sets.
Update 11/07/2016: The input lag results have been updated with the newest firmware update 04.30.40, but the results remain largely unchanged. Note that the HDR input lag still cycles, which may be an issue for gamers. A video showing the cycling can be seen here, and a full table of the results can be found below. We will continue to update these results with any further firmware updates.
Note that ranges of numbers show the variance in the cycle of the result.
|1080p @ 60Hz||27.6ms|
|1080p @ 60Hz @ 4:4:4||62.9ms|
|1080p @ 60Hz @ HDR||28.2ms|
|4k @ 60Hz||27.8ms|
|4k @ 60Hz @ 4:4:4||70.9ms|
|4k @ 60Hz @ HDR||28.5ms|
Update 11/08/2016: Some owners have started a petition to LG to address these issues. This can be found here.
After some more testing we have found that none of the LG TVs support chroma 4:4:4 when in a HDR picture mode, regardless of the input icon. This can be seen here .
Update 01/05/2017: With the newest firmware update (04.30.77) the input lag has been reduced across all resolutions. A 'HDR Game' picture mode has been added, and the input lag no longer cycles over time. The results above have been updated.
Update 02/07/2017: Note that in the 'HDR Game' picture mode there is some screen tearing in the bottom 1/4inch of the display. This does not affect the other picture modes.
Update 03/06/2017: Retested the B6 with the latest firmware update (04.31.10) and the screen tearing issue in 'HDR Game' picture mode is now fixed. Input lag remained the same as with the previous update
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
To enable Chroma 4:4:4 support, first go in the 'General' menu, then enable 'HDMI ULTRA Deep Color' for the HDMI port that you are using. After, change the input icon to PC in the 'All inputs' menu, accessible thru the remote input button. Under PC mode, the input lag is 70.9 ms at 4k.
On the LG B6P, when a Bluetooth device is connected, the 'Game' picture mode is unavailable.
The LG B6P provides a response which is better than most TVs, but unfortunately there is distortion across all volumes and the TV doesn't get loud.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
Very good frequency response, for a TV, especially at lower volumes. Lowend cutoff of 90Hz and maximum loudness of 87.6dB are not great, but decent. However, at higher volumes, some pumping and compression may be present. Also, it won't be able to produces the punch and low-end thump that external speaker/sub systems are able to produce.
Poor performance. The amount of total harmonic distortion at 75dB is excellent. However, there is a noticeable rise in the amount of harmonic distortion under heavier load, especially at maximum volume, where it could be audible is certain situations.
The B6 features WebOS 3.0, which provides a very responsive interface and is easy to use. Popular applications such as YouTube, Netflix and Amazon Video come pre-loaded and the 'LG Content Store' provides a wide range of applications to extend the viewing experience. The number of available applications is increasing all the time. The remote is similar to the EG9600 and provides a pointer for easy navigation.
The remote is much smaller than the E6, and is the same as the UH8500. Although it looks less premium than the E6, the smaller size is more comfortable to use. It features a pointer controlled by the remote movements to navigate menus. Although there is a 3D button, the TV does not have the feature.
Differences between Sizes and Variants
We tested the 55" (OLED55B6P). For the most part, we expect our review to be valid for the 65" (OLED65B6P).
If someone comes across a different type of panel or if their LG OLED 55B6P doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
Compared to other TVs
The LG OLED B6 performs quite similarly to the higher end LG OLED E6, as well as last year's OLED TVs. As an OLED it can't be beaten on picture quality, but this comes at a high price. Keep that in mind with our recommendations below.
The E6 is a higher end model in the same line up as the B6. It provides the same excellent picture quality but boasts slightly lower input lag and improved sound over the B6, as well as 3D. For gamers with a large budget it is the best TV you can buy, but for everyone else the B6 provides the same experience at a lower price.
The KS8000 is a great overall TV. It provides deep (but not perfect) blacks and an impressive picture quality when viewed from the front, but for home theatre viewing it just can't beat dark scene performance of an OLED TV. For those who don't quite have the budget for an OLED the Samsung KS8000 is our next recommendation.
The Vizio P Series 2016 is a budget home theatre TV. It doesn't provide the perfect blacks or excellent motion of the B6 but offers good performance for those on a strict budget. It is good for gamers though, due to the low input lag. For those on a tighter budget the Vizio P Series 2016 is a good choice, but if you can afford it go with the B6.
The Sony X930D has a worse native contrast ratio, and overall worse picture quality. The picture quality degrades when watched from a slight angle. This is not recommended as there are other TVs in the same price range with better picture quality and features.
Questions & Answers
For most people, this input lag is not noticeable. Even with a 60fps signal, the difference between 54ms and 34ms is about 1 frame. We have re measured our B6 with the newest firmware and can confirm the 54.3ms measurement. This is with the input icon set to 'Game Console' and the picture mode set to 'Game'. The picture quality of this TV is exceptional.
Update 11/11/2016: With the newest firmware update, the input lag for 1080p @ 60Hz is now 44.4ms.
Sorry to bother you guys but today I had a day off and I just spent 5 hours to read this thread from page 735 till 768. The thing is: LG fucked up with the firmware bigtime! And this is just one topic in one language (you have many topics like this in dutch/german/italian etc etc and also on different websites). So it is not just one country and one little issue. If you call/e-mail LG, they don’t know shit or they give us some bullshit answers. LG support is like Hell.
We customers pay a lot of money for these OLED’s but LG doesn't care and I think you will agree with me: this has to stop. Most users on this forum are complaining about the following after update 05.30.03:
- No more perfect black anymore -> glow
- Menu is laggy (mostly with 4k input) sometimes also after factory reset
- Loss of contrast
- Banding in some hdr movies
- When in PC MODE: greenish picture in all HDR modes or too dark
- WIFI not working properly anymore (also for c6)
- Bad stuttering with motion
- Causing screen tearing on OSSC (a line multiplier to upscale retro consoles and it outputs 1080p)
- Text is very blurry now with occasional blue/red banding in PC MODE
I also think they can easily reduce the input lag for PC mode (4:4:4) but LG doesn't care. And what about the HDR Game mode, that is way too dim? That’s not okay for a high end tv. I bought this tv for pc gaming, but I can’t enjoy it to the max. Anyway, the reason I e-mail you guys is because I think you guys are honest, independent and not paid by LG or Sony etc to do a TV review. Many review sites won’t say shit about this, because they get paid by TV companies and I hate that because we customers get screwed. I hope you will investigate this … and I promise you, the community (from av till avs till neogaf till tweakers etc) will love you guys for making an article about this because the b6 is one of the best selling tv’s … even now!
Sorry for this long e-mail but I’m a little upset and want justice ?? Greetings from Holland and keep up the good work! X
The B6 isn't perfect, but as with the other OLEDs it is one of the best all-round TVs we have reviewed. As you have noted, the biggest issues with gaming on the B6 are the average input lag and the temporary image retention on static content. The difference between the B6 (or EF9500) and the E6 with input lag is ~20 ms. For most people, this should not make a difference. With a 60fps game this results in the command occurring 1 frame later.
The biggest advantages the B6 has over the EF9500 is the higher peak brightness and wider color gamut. For gaming, this should not make a difference. Unless you plan to watch a lot of HDR content go with the cheaper one. The picture quality of an OLED is better than any LCD at the moment.
We did recheck the input lag after the last firmware update (03.15.25) and there was not any change. It was still 54.3 ms.
Update 11/11/2016: With the newest firmware update, the 1080p @ 60Hz input lag is now 44.4ms.
