The Similarities and Differences between LG OLED B6 and B7
As we see on comparison table above, as a newer model, LG OLED B7 comes with some additional features and technology than OLED B6, but not a lot. They use similar panel that is OLED panel with RGBW pixel, but they are powered by different HDR engine. OLED B6 is powered a picture engine named Perfect Mastering engine with OLED HDR engine, while OLED B7 is powered by an HDR engine named Active HDR. Meanwhile, as a newer model, OLED B7A also already supports more HDR formats than OLED B6P. For this case, LG OLED B6 supports HDR 10, Dolby Vision, and with a firmware update, it also might support HLG. On other hand, OLED B7 already supports most of HDR formats that available in the market including HDR 10, Dolby Vision, HLG, and advanced HDR. Additionally, OLED B7A has a new feature named “HDR Effect” that allows you to enjoy any contents with quality as close as 4K HDR, while OLED B6P doesn’t has this feature. The other difference between them is about their sound performance. Although both of them equally have 4.0 speaker system with 40 watts of total power speaker, but the sound system of OLED B6 is powered by HarmanKardon, while OLED B7 is not. On other hand, with a firmware update, LG OLED B7 already support Dolby Atmos, while OLED B6P doesn’t support Dolby Atmos. Nevertheless, since sound performance of OLED B7A is less powerful and it doesn’t have built-in sub-woofer, to enjoy Dolby Atmos experience, you need an external sound bar.
The other difference between LG OLED B6 and B7 is about their connectivity, particularly Composite In (AV In). For this case, OLED B6 has 1 Composite In (AV In), while OLED B7A doesn’t have AV In. Additionally, although essentially both of them featuring WebOS as their platform, but the version of their platform are also different. OLED B6P comes with WebOS 3.0, while OLED B7 comes with WebOS 3.5. For this case, as a newer version, WebOS 3.5 is powered by a new chip that makes its performance is faster and more responsive. Additionally, WebOS 3.5 also comes with the number of new features like Magic Link, 360 Degree Videos, and others.
Coming with OLED Panel, both LG OLED B7 and B6 equally have infinite native contrast ratio and perfect black level, makes both of them equally have excellent dark room performance. Additionally, OLED panel also makes both of them have wide viewing angle coverage, makes them can maintain their excellent picture quality from any angle. Not just that, since OLED panel has extremely low pixel response time, this certainly also makes both of LG OLED B6 and B7 has great motion handling, result in smooth and clear picture quality with almost no motion blur when playing fast moving images.
For maximizing their rendition of colors, in addition to RGBW sub pixel that makes them already support wide color gamut, both of LG OLED B6 and B7 are also equally powered by Tru Color Accuracy, makes the color of the picture displayed on their screen looks very accurate. Additionally, both of them also equally support 10 bit depth of color that makes the color gradient of the picture produced by them looks very smooth, particularly when playing HDR contents. Meanwhile, for maximizing their peak luminance, LG OLED B7A and B6 are also equally powered by Ultra Luminance. Essentially, the excepting of what we have mentioned on their difference section, both of LG OLED B6 and B7 are powered by similar technology and have similar features.
LG OLED B7 vs OLED B6 Performance
Picture quality is one of the main advantages of LG OLED B7 and B6. Since OLED Panel has self lighting pixel and doesn’t use backlight, this allows the screen don’t emit any light at all when showing totally black. The result, blacks colors produced looks perfect. Combined to its excellent black uniformity, this makes dark scene of images displayed on their screen look excellent, particularly when set in a dark room where the effect of high native contrast ratio is very influential. Not even just that, when playing HDR videos where contrast ratio is one of major components, contrast ratio of OLED B6 and B7 is also quite strong to reveal details images in dark scenes. No matter they are playing HDR 10 videos, Dolby Vision, or other HDR formats, they can show shadow details of HDR images excellently like what intended by HDR technology itself. As we know, to show shadow details of HDR image like what intended, particularly when showing HDR 10, and one of the terms to get Ultra HDR Premium Certification set by UHD alliance, an OLED TV must be able to reach 0.0005 nits of black level or darker. This means, with nearly 0 nits of black level, to show shadow details of HDR images like what intended, both LG OLED B7A and B6P don’t have any problem.
Meanwhile, discussing about their peak brightness, there is a bit improvement on OLED B7 over B6.Overall, peak brightness of OLED B7A is a bit brighter than OLED B6P, whether it they are inputted by SDR or HDR signal. As the note, OLED B7 can reach its peak luminance at brighter than 800 nits in small area of window test, while peak brightness reached by OLED B6 is still brighter than 700 nits, but still below 700 nits. This certainly makes OLED B7A can show small highlight of HDR images a bit brighter than OLED B6P. Nevertheless, essentially, peak brightness of LG OLED B6 and OLED B7 is fairly good for OLED TV. Peak brightness reached by them is even quite bright to fight the glare of ambient light, result in consistent excellent picture quality, no matter the light condition of a room they are used, even when they are set in a room with very bright light or sunny window. Additionally, their peak brightness is also quite bright to show highlight of HDR 10 images like what intended. Unlike LED TV, where the minimum recommendation to get Ultra HD Premium Certification set by UHD Alliance is 1000 nits, OLED TV has lower standardization that is 550 nits. With brighter than 700 nits of peak luminance, this certainly makes both of them can show highlight of HDR images fully like what recommended by UHD alliance. But since most of HDR images usually are mastered in 1000 – 4000 nits of brightness range, both of OLED B7A and B6P certainly cannot show highlight of HDR images as bright as the native brightness of HDR images. This certainly makes their performance is less powerful than premium LED TV like Sony X930E or Samsung Q9F series that has peak luminance brighter than 1000 nits. Nevertheless, essentially, their peak brightness is really great for OLED TV and quite bright to show highlight of HDR images fairly well.
Both of LG OLED B7A and B6P already support excellent color gamut and their color gamut is similar. Color gamut reached by them is even including the best, a bit less than Samsung QLED TV as a TV with the widest color gamut in 2017.The result, almost all colors in DCI P3 of HDR images can show properly, makes the color of the picture displayed on their screen looks fairly accurate. Additionally, color gamut delivered by them also can cover colors in Rec.2020 color space fairly well. However, like most of modern TVs, when showing saturated green, the result might not as good as other colors. Nevertheless, colors of images that mastered in Rec.2020 like Dolby Vision contents still looks very accurate. Additionally, both of the also equally have good color volume. Both of them can show their wide color gamut almost in all their brightness range, even in extremely low luminance. A bit unfortunate, their color gamut will a bit narrows at nearly their peak brightness due its RGBW pixel structure doesn’t allow to that. Still about color performance, both of them also already support 10 bit depth of color that means they can deliver more than 1.07 billion shades of color. The result, color gradient of the picture displayed on their screen looks very smooth without any major issue. In darker color, some little imperfection might still visible, but overall, their color gradient is excellent. Combination of wide color gamut, good color volume, and smooth color gradient, this certainly makes LG OLED B6P and OLED B7A have excellent rendition colors.
Meanwhile, to anticipate the many of lower resolution contents which available in the market, both of LG OLED B7 and B6 are equipped great 4K up-scaling engine called Tru 4K Up-Scaler. No matter the resolution of the video source, it will be up-convert as close as to 4K resolution. The result, low resolution contents like DVD movies with 480p resolution looks sharply and clearly in 4K quality. And of course, the higher resolution of the source, the final images in 4K produced by them will look sharper and clearer with small details are preserved better. The ability of OLED B7 is even not just that. It also has a new feature named HDR effect where when be enabled, it can improves the brightness and color range of the picture, so you can enjoy any content with the quality as close as 4K HDR. Meanwhile, OLED B6 doesn’t yet have this feature.
The other superiority that offered by LG OLED B7 and B6 is about their wide viewing angle coverage. As we know, since OLED panel doesn’t use backlight, this makes it has extremely wide viewing angle coverage, even far better than LED TV with IPS panel. The result, both of them are able to maintain their excellent picture quality from any angle. This means, when you are watching TV from a wide angle, the picture displayed on their screen will look as good as when viewed from the front and center. This certainly becomes its advantages than LED TV considering most of premium LED TVs have an issue on side viewing angle. This certainly also give a benefit when they are used in a wide room where the viewers watch TV from multiple angles.
Winner: OLED B7 has a bit brighter peak brightness
Motion Handling and 24p Playback
In addition to excellent picture quality, both of LG OLED B7 and OLED B6 also have great motion handling. As we know, one of the advantages of OLED panel than LED panel is about its extremely low pixel response time. As the note, until now, the fastest pixel response time reached by LED TV is about 3 ms, while OLED panel can reach up to 0.1 ms, far lower than LED TV. The result, when playing video contents with fast moving scenes like sports or fast movies, the picture displayed on their screen looks very smooth and clear. Following fast moving object, there is only an extremely short trail where most of people might not notice. Meanwhile, when playing 24p movies, there is an improvement performance on OLED B7 over OLED B6. LG OLED B6 is only able to deliver judder-free picture when it is playing 24p videos like Blu-Ray movies, while when playing 24p movies via 60p signal like movies from streaming devices or 24p videos via 60i signal like movies from satellite TV, it cannot remove the judder completely. Meanwhile, no matter the source of the movies, whether it is native 24p videos, 24p videos via 60i signals, or even 24 videos via 60p signal, OLED B7 is able to deliver judder-free picture. Nevertheless, to remove judder without adding soap opera effect on OLED B7, you should make a certain setting on their “picture option” by activate “Real Cinema” option, set “TruMotion” option to “User”, and set both “De-Blur” and “De-Judder” to “0”. Additionally, since both of them have native 120 Hz refresh rate panel, this certainly also makes them are able to play both lower frame rate content 30 fps and 60 fps.
Winner: OLED B7
As their major connectivity, both of LG OLED B7 and OLED B6 equally equipped with 4 HDMI ports and 3 USB ports (2 USB 2.0 and 1 USB 3.0). All of their HDMI ports already support HDCP 2.2 and other formats. Meanwhile, their HDMI port that already supports ARC is HDMI 2. A bit difference, ARC of OLED B7 can pass through Dolby Atmos signal while OLED B6 cannot. In addition to HDMI and USB, there are also 1 Composite In (AV In), RF In, Ethernet In, and Digital Audio Out. A bit difference is about Component In where LG OLED B6 has 1 Component In while OLED B7 is not equipped with this input. Meanwhile, talking about their input lag, there is a significant improvement on OLED B7 over OLED B6, particularly in “PC Mode”. The input lags of OLED B7 are similar at 4K and 1080 in “PC Mode” or “Game Mode that is about 21 ms. Although this might not as low as SJ8500, this certainly is low enough to play any game so feel responsively without laggy, even for fast paced games which required fast reflexes. On other hand, the input lag of OLED B6 is low only in “Game Mode” that is about 28 ms at 4K and 1080p resolution. Although not as comfort as OLED B7, play game on OLED B6 also still feel responsively. Meanwhile, in “PC Mode”, the input lags of OLED B6 are too high, that is about 60 ms at 1080p resolution and 70 ms at 4K resolution.
Winner: OLED B7
As we have mentioned above, they might equally featuring WebOS as their smart TV platform, but as a newer model, LG OLED B7 also comes with newer version of Web OS. For this case, it featuring WebOS 3.5 while LG OLED B6 feature WebOS 3.0. According to the manufacture, the newer version of WebOS comes with some improvements and is supported by a new chip that makes its performance is faster and more responsive. Additionally, WebOS3.5 also comes with some additional features that makes it is more attractive like 360 degree videos, Magic Sound Tuning, Magic Link, and more. Meanwhile, in term of interface, there is not many changes. The user interface of WebOS is still looks simple but attractive. Across the bottom of the screen, there is a strip bar contains quick access to a lot of most popular and your favorites apps and smart features. Meanwhile, discussing about apps provided, the excepting of the new features on WebOS 3.5, essentially, both of them provide a lot of attractive and useful apps. As their preloaded apps, there are VoD Service like YouTube, Netflix, Amazon Videos, and many more, Web Browser, Games, Live TVs, and many more. Additionally, both of them also has apps store named “LG apps Store” that provided tons of downloaded apps, games, and contents where you can directly download them from you LG OLED TV. Although not as complete as Samsung apps store or Google Play Store, the apps, games, and contents provided are also very complete.
As their controller, they equally come with smart remote named “LG Magic Remote”. At a glance, their remote are similar. Although the remote is a bit large, but it comes with some useful smart features and attractive design. Both of these remote are equally equipped with built-in microphone, allows you to make a setting or control TV functions with your voice command. Additionally, both of these remotes also equally have universal capability, allow you to control some functions of other devices connected on your LG TV with a single LG remote. The most interesting and that becomes the advantage than other smart remote, they have “point and click” functionality, makes you more comfort and easy when navigating. In the center of the remote, there is a “scroll wheel” that allows you to point and click an app or features what you want to open. This is like a mouse on your PC or laptop. Meanwhile, a bit difference between their remote, on the remote of OLED B7, there are “Amazon Videos” and “Netflix”, allow you to open Netflix or Amazon Prime Video directly without entering the main menu of smart TV.
|Performance||LG OLED B6 (B6P)||LG OLED B7 (B7A)|
As a newer model, LG OLED B7 comes with some improvement over OLED B6 that makes its performance is better. Its peak brightness is a bit brighter, makes OLED B7 can show brighter highlight of HDR images than OLED B6. Additionally, OLED B7 now can show any source of 24 videos with judder-free, while OLED B6 still have an issue when playing 24p movies via 60i signal or 60i signal. The other improvement on OLED B7 over LG OLED B6 is about their inputs lag where LG OLED B7 has lower inputs lags in “Game Mode” and “PC Mode”, makes it is more comfort when used to play games, particularly for fast paced games. The other advantages that offered by OLED B7, it already supports Dolby Atmos, allow you to enjoy Dolby Atmos Experience in your home. But unlike the higher series, you need an addition external speaker to be able to enjoy Dolby Atmos with OLED B6. Additionally, there are also some improvements on WebOS 3.5 as the platform of OLED B7 over WebOS 3.0 as the platform of OLED B6. Nevertheless, ignoring some improvements on OLED B7, picture quality and performance of OLED B6 is also excellent.
So, which is a better choice between them? Although LG OLED B6 has been discontinued by the manufacturer, but some merchant still have some stocks and sell it. Nevertheless, it certainly sold cheaper than OLED B7. Now, the decision certainly comes back to your own preference. If you don’t mind to spend more about hundred dollars to get newer model and some improvements offered, LG OLED B7 might be a better choice for you. But even so, if you want a little frugality, performance of OLED B6 is also not far behind OLED B7. But once again, their price might not fixed and change at any time.
