The main Differences between LG OLED C8 and OLED B8
If in last year, the differences between OLED B7 and C7 are on their design and audio equipment, in this year, LG OLED B8 and C8 also has a difference in design, particularly on their stand. The stand of OLED B7 is almost similar to OLED C7 of last year model. Its stand is quite narrow, makes it is small enough to fit on most tables. However, it can support TV well and sturdy, and with a brushed metallic finish, it looks elegant on your table. On the other hand, the stand of OLED C8 is wider than B8, up close to the full width of the TV. It is made of aluminum with a hard plastic finish. This certainly makes it can support the TV more sturdy than the stand of OLED B8, but on the other hand, it is hard to fit on some tables. Meanwhile, on their main panel, it looks almost identical, no matter they are viewed from the front, side or back.
The main difference between LG OLED B8 and C8 is on the processor that supports them. LG OLED B8 is still powered by Alpha 7 Intelligence processor, the same processor that also used by all models of LG’s 2017 OLED TV lineup including B7A, C7, E7, and others. On the other hand, LG C8 is already supported by Alpha 9 Intelligence processor, the same processor that also be used by other higher model of L’s 2018 OLED TV including E8, or even W8. Alpha 9 processor as a higher type brings some advantages than Alpha 7 processor. One of the impacts is on their performance when handling 120 fps videos or called HFR (High Frame Rate). Both LG C8 and B8 might be equally already support HFR and HDR, but with Alpha 9 Processor, LG C8 is more powerful enough to handle HDR and HFR simultaneously. On other hand, LG B8 with Alpha 7 processor has limitations in handling HFR. OLED B8 might be able to handle both HDR and HFR, but it cannot handle them simultaneously like a TV with Alpha 9 processor like C8. Additionally, OLED C8 with Alpha processor also can provide smoother and clearer picture at 120 Fps, particularly when they are playing fast moving images. But even so, since their HDMI ports support HDMI 2.0 only and have not support HDMI 2.1, their HDMI ports don’t accept HFR due the lack of sufficient bandwidth. This means, for a while, they are only able to accept HFR contents via USB. On the other hand, since there are not many 120 fps contents released, for a while, this doesn’t give any practical advantage to OLED C8 against OLED B8.
The other advantage offered, Alpha 9 processor also provides four-step process of noise reduction, while alpha 7 Processor only provides two-step processing. This makes LG OLED C8 can provides better clarity of images and smoother color gradient. Additionally, Alpha 9 processor also provides better color performance the alpha 7. In addition to has an effect on their performance in processing images, the use of Alpha 9 also makes performance of its Smart TV is faster and more responsive than OLED B8, though both of them are featuring the same Smart TV platform and features.
The level of True Color Accuracy Technology
As we see on comparison table above, the other difference between LG OLED B8 and OLED C8 is on the level of their True Color Accuracy technology where LG OLED C8 comes with Tru Color Accuracy Pro while OLED B8 comes with standard Tru Color Accuracy. As a result, OLED C8 with Pro Version can provide better color correction than OLED B8 with standard version. This should makes the color accuracy of images produced by OLED C8 is better than OLED B8.
Features and Technologies of LG OLED B8 and OLED C8
The excepting of what mentioned above, LG OLED C8 and OLED B8 have similar features and are also powered by the same technologies. Both of them equally use OLED panel with 2160 x 3840 of resolution. In addition they can provide four-times more details picture quality than 1080p picture, with OLED panel, it also can provides infinitive native contrast ratio and perfect black level. Additionally, with 4 sub-pixel color technology (RGBW), both of them also can provide wide color gamut and excellent color reproduction. But as we have mentioned, for maximizing its color reproduction, they are powered by different level of Tru Color Accuracy where the impact have been discussed above. For maximizing peak brightness produced, both of them are also equally powered by Ultra Luminance Pro Version Technology.
Equally maximized for HDR experience, both of them already support most of HDR formats which available in the market including HDR 10, HLG (Hybrid Log Gamma), Dolby Vision and Advanced HDR by Technicolor. The only most popular HDR formats that is not supported by them is HDR10+ where for a while, this format is only supported by Samsung TV. In addition to what mentioned, there are also Tru 4K Up-Scaler, Intense Color, Billion Rich Color, and other features behind them.
As their Smart TV platform, both LG OLED B8 and C8 are equally featuring WebOS 4.0 with ThinQ AI. As we know, In addition to allow you can do a lot of thing with your voice command, LG ThinQ also acts as a HUB for your compatible home device like Dish washing, Laundry machine, and others. As their controller, both of them are also equally equipped with LG’s magic remote which has a lot of useful features. And for providing impressive sound quality when you are enjoying HDR experience, both LG OLED B8 and OLED C8 are equally equipped with 2.1 channel speaker system that already supports Dolby Atmos.
LG OLED B8 vs OLED C8 Performance
Contrast and Black Level
As we know, since both LG OLED C8 and B8 equally use OLED panel, this certainly makes both of them have infinite contrast ratio and perfect black level. Additionally, OLED panel also makes them has perfect black uniformity. This certainly makes their excellent performance in a dark room is undoubtedly. Since they have perfect black level, details of images in dark scene of HDR images can be revealed excellently, make shadow details of HDR images also looks excellent like the content creator’s intended, even when they are set in a dark room where the impact of high contrast ratio is very sensitive. Additionally this also makes them can show darker color fairly accurately, even for extremely dark colors. Combination of perfect black level, perfect black uniformity and accurate darker colors certainly makes dark scene of images displayed on their screen looks very amazing, particularly when they are showing HDR images. With their great performance in showing dark scene, this certainly makes them as a great TV when used for watching movies with a lot of dark scenes like horror or thriller.
While both of them the equally have perfect black level, in regard peak luminance, LG OLED C8 has brighter peak brightness than OLED B8, no matter they are playing SDR or HDR contents. When playing SDR content, peak brightness of OLED C8 is a bit brighter than OLED B8, but essentially, their peak brightness is quite bright to overcome the glare. Additionally, both of them also equally have excellent performance in handling reflection. The result, combination between bright peak brightness and excellent reflection handling certainly makes the picture displayed on their screen looks remain excellent when set in a bright room. But a bit unfortunately, when showing a scene with all object are bright, their brightness dim to below 200 nits due it is limited by ABL. (Automatic Brightness Limiter).
Meanwhile, when playing HDR contents, both LG OLED B8 and OLED C8 also can produce brighter peak brightness. But like when playing SDR content, LG OLED C8 can produce brighter peak brightness than OLED B8. Overall, when playing HDR content, their peak brightness is close to 700 nits, makes HDR images displayed on its screen looks excellent in most room. Even when showing small window size, it can produce peak brightness about 900 nits, makes highlight of HDR images displayed on its screen looks excellent. But even so, since its peak brightness is still less than 1000 nits, it cannot show highlight of HDR images at 1000 – 4000 nits like the creator’s intended. On other hand, its peak brightness is also drop significantly when showing a scene with the whole of screen is bright, its peak brightness is drop significantly below 2000 nits. But overall, peak brightness of LG OLED C8 is great for OLED TV.
Meanwhile, although not as bright as OLED C8, LG OLED B8 still has good peak brightness. When playing HDR movies, its peak brightness is nearly 600 nits that means it is still bright enough for most room. It also can show small window size is brighter than 700 nits, makes highlight of HDR images looks excellent. But since its peak brightness is not as bright as OLED C8, the highlight of HDR images displayed on the screen of OLED B8 is also not as bright as what be shown by OLED C8. And of course, it also cannot show highlight of HDR images brighter than 1000 nits like the intended. Additionally, like LG C8, peak brightness of LG B8 also drops significantly when showing a scene with the whole of screen is bright. But overall, although not excellent as OLED C8, for OLED TV, peak brightness of OLED B8 is still good. Its peak brightness even is still brighter than 550 nits as the minimum recommendation set by UHD alliance that means it is good for most rooms.
Winner: OLED C8
Both LG OLED B8 and OLED C8 equally have excellent color gamut, only a bit worse than Samsung Q7FN as the TV with the best color gamut in 2018. Their DCI P3 coverage is impressive and nearly close to 100%, makes most of colors of HDR images mastered in DCI P3 like HDR 10 contents can shown fairly accurate, even for deep greens where most modern TVs struggle to show these colors fairly accurate. Additionally, its color coverage in Rec.2020 also fairly good, make colors of HDR images mastered in Rec.2020 like Dolby Vision contents also can be shown fairly accurate. But a bit unfortunate, their color volume is not so good and far below Samsung Q7FN. In producing deeper colors, particularly for extremely dark colors, performance of OLED B8 and OLED C8 might be better than Q7FN, but its wide color gamut narrows significantly at around of their peak brightness, makes very bright colors cannot be shown fairly saturated. But even so, this problem should only affect on the colors of very bright highlight of HDR images, while overall, the excepting of extremely bright colors, they can well-show their wide gamut at their brightness range. While their color gamut and color volume is not as good as Samsung QLED TV lineup, particularly Q7FN or higher model, both LG OLED C8 and OLED B8 equally have excellent color gradient, better than Samsung QLED TVs. Both of them can show color gradient of HDR images smoothly with almost no color bandings. Some little imperfections might still be visible at certain colors but this should not be a problem for normal contents. Or if you are very sensitive to this imperfection, you can enable “MPEG Noise Reduction” on their picture setting, but in the other hand, this will make a fine details of picture will lose.
Side Viewing Angle
As we have known, one of the major advantages of OLED panel than LED panel is about its excellent side viewing angle coverage. If on LED TV particularly TV with VA panel, the picture will look degraded when viewed from the side, on the screen of OLG OLED B8 and OLED C8, the picture displayed will look more consistent at wider angle. Color might still look fade at less than 30 degrees off center and front, but at wider angle, the color degradation is not as significant as on LED panel. On other hand, their excellence is about their ability in maintaining black level and brightness at wide angle, even at extremely wide angle. The result, when viewed from the side, the picture degradation is not as striking as on the LED TV, even on their screen, the picture degradation is not too visible. Whet offered by OLED B8 and OLED C8 even is far better than what offered by IPS TV that also be maximized for providing wide viewing angle coverage.
Motion Handling and 24p Playback
The other major advantage of OLED TV including LG OLED C8 and OLED B8 is about its extremely low pixel response time, far lower than LED TV. When they are playing fast moving images like sports or fast games, the picture displayed on their screen looks very smooth and clear with no ghosting trail behind fast moving object. Meanwhile, since OLED TVs don’t have backlight, this allow them has flicker-free. But on the other hand, this will result in some persistence blur. But for this case, LG OLED B8 and OLED C8 equally have an optional flicker mode (BFI mode) at 60 Hz. This feature is very helpful to clear-up the motion particularly when playing 60 fps content like sports or video games. For enabling this feature, you just need set “on” the “Motion Pro” on its picture setting. By enabling this feature, motion may be looks clearer, but on the other hand, this will make flicker will be visible. Additionally, since both of them have native 120 Hz refresh rate panel, both LG OLED C8 and OLED B8 are able towel- interpolate both lower frame rate content 30 fps and 60 fps.
Meanwhile, when playing 24p movies, LG OLED B7 offers a bit better performance than OLED C7, particularly when playing 24p videos via 60i signals like movies from satellite TV. For this case, OLED B8 can play the movies with this frame rate with judder-free while OLED C8 cannot remove the judder completely. But even so, the excepting of 60i movies, their performance is similar. Whether it is native 24p videos like DVD or Blu-Ray movies, 24p videos from streaming apps like Netflix, Amazon Videos, and others, 24p videos via 60p signal like movies from streaming devices or PC, both of them can play them smoothly and clearly with judder-free. In order to they can play 24p movies with judder-free, you must make some certain settings on their picture setting like turn on the “Real Cinema”, set “Tru Motion” to “User”, and set both “De-Judder” and “De-Blur to “0”.
Winner: OLED B8 offers better performance in handling 24p movies
Both LG OLED C8 and B8 are equipped with the same inputs/outputs. As their major connectivity, they are equally equipped with 4 HDMI ports where all of them already support HDCP 2.2, HDMI 2.0 Full Bandwidth. Meanwhile, they also equally have 1 port that support ARC (Audio Return Channel) that is HDMI 2. But a bit unfortunate, their HDMI ports have not support HDMI 2.1 for playing HFR or 120 fps contents via HDMI port. Like we have mentioned, although both of them already support HFR, but since their HDMI ports don’t support HDM 2.1, their HDMI ports don’t accept HFR and they can play HFR contents via USB only. Additionally, both LG OLED B8 and C8 also equally equipped with 3 USB ports. But unlike the last year model where they support USB 3.0, both OLED C8 and B8 don’t have USB 3.0 and all USB ports of them are USB 2.0. In addition to HDMI and USB ports both of them are also equally equipped with 1 RF In (Antenna In), 1 Ethernet Port, and 1 Digital Audio Out (Optical). There are no Composite and Component In behind In. As their wireless connectivity, they are equally equipped with built-in Wi-Fi and Bluetooth.
Meanwhile, LG OLED C8 and B8 also have almost identical input lags in PC and Game mode. Although not the lowest, their input lags are still less than 25 ms that means it is great for any games, even for fast paced games that required fast reflexes. Combined to their excellent picture quality and motion handling, this certainly makes them as great TVs for video games. But keep in mind, since OLED panel has a risk to permanent burn-in, play a same game for a long time should be avoided.
As their smart TV platform, both LG OLED B8 and OLED C8 are also featuring the smart TV platform that is WebOS 4.0. But for this case, since OLED C8 is powered by Alpha 9 processor, this makes its performance is a bit faster and more responsive than OLED B8 that powered by Alpha 7 Processor. Nevertheless, although its performance is a bit less smooth than OLED C8, but it is still smoother than competitors like Samsung QLED with Tizen OS or Sony TV with Android TV. But even so, the excepting of in regard performance, they are almost identical. As we know, in this version WebOS has been integrated with LG ThinQ AI, a home intelligence app by LG. In addition to it acts as a HUB for controlling your LG’s ThinQ AI compatible devices, it also allows you to do a lot of things with your voice command. Meanwhile, in term of user interface, there are not many changes over last year version. User interface of WebOS is still simple and easy to navigate with a “strip bar” at the bottom across the screen contains a lot of “tiles” as the shortcut of apps, settings, and inputs. A bit change over last year is on the top right where there is a new quick access button to search function. Meanwhile, discussing about apps installed, provided, there are a lot of attractive and useful apps provided. There are VoD services like YouTube< Netflix, Amazon Videos, and others, Live TV, Games, Web Browser, and many more. Additionally, like other smart TV platform, it also has an apps store called “LG apps provide”. Although apps provided are not as many and complete as Google Play Store or Samsung Apps store, but what provided by LG apps store are also a lot and even is more focused on what people want.
As the controller, both LG OLED C8 and B8 are also equally equipped with the “Excellent” LG’s magic remote. The remote is nearly identical to what used by last year models. In addition to standard buttons like “numbers buttons”, power button, and others, it also has some it also has two dedicated buttons for quick access to Amazon and Netflix. At the center of the remote, there is a combination of a scroll wheel and direction pad that makes navigation and access to all options is easier and quicker. Not just that, when pointed to the TV, the remote can acts as pointer, allow you to move the pointer on the screen by moving the remote. Like other smart remote, this remote is also equipped with built-in microphone for voice navigation. Since it is integrated with LG’s ThinQ AI, its voice command works much better. Not just TV functions and menu that can be controlled by your voice commands, but also other LG’s ThinQ compatible device like dish washer, air conditioner, lights, and others. It even is also compatible with Amazon Alexa and Google Home. This remote also has a universal ability, allow you to control other CEC compatible device connected via HDMI ports with a single LG remote.
Winner: OLED C8 offers a bit more responsive performance
|Performance||LG B8||LG C8|
As we have discussed a lot above, the major difference between LG OLED B8 and OLED C8 is the processor that supports them. With Alpha 9 Processor, C9 can do a better job than OLED B8 with Alpha 7 Processor like handing 120 Hz (HFR) content, smart TV performance, color accuracy and others features. Meanwhile, OLED C9 also can provides brighter peak brightness than OLED B8, makes the picture displayed on its screen looks brighter. The impact will be noticeable when they are playing HDR content in a bright room. While the excepting of what mentioned, their performance is almost identical and essentially, both of them equally have excellent picture quality and great performance on some features offered like wide viewing angle coverage, excellent motion handling, low input lags, and attractive and responsive smart TV platform. Essentially, both LG OLED B8 and C8 are great TVs for mixed usage, whether for watching movies, TV Shows, sports, or playing games.
So, which is a better choice between them? As we have mentioned above, with the same screen size, LG OLED C8 is sold about one two hundreds dollar more expensive than OLED B8, while the benefit of the use of alpha 9 processor on OLED C8 is not too noticeable for this time. The difference between them that is a bit noticeable is about their peak brightness, particularly when they are playing HDR content, while when playing SDR contents, their peak brightness is almost similar. Now, the decision comes back to you according to your own preferences. Since OLED C8 can handling HFR contents better, for the long term, it is a better choice. Nevertheless, OLED B8 is also a good choice for you who want a cheaper model, considering its picture quality and performance is not far behind OLED B8.
