LG OLED55C6P vs LG OLED55B6P Review: Which is the better choice?

The LG OLED55B6P and the LG OLED55C6P are part of LG’s OLED TV lineup for the B6P and C6P series.  They are sold for a similar price but come with a different feature set. Essentially both of them offer a virtually identical excellent picture quality on SDR content and on HDR content. Talking about HDR, both the LG OLED55C6P and the LG OLED55BP handle both HDR formats being HDR 10 and Dolby Vision. In order to process HDR sources well, both are supported by the Perfect Mastering Engine with HDR Super and Dolby Vision for their image processor. Of course, there are a number of LG’s containing their most advanced technologies to improve performance.

The main key to the superb picture quality offered by each is their perfect black level and infinite contrast ratio. This is due to each having pixels of OLED TV that can switch on/off/dim individually.  You need to know that with self lighting pixels, the condition of each pixel is not affected by the condition of the other pixels surrounding it, this seems fair that the LG OLED55B6P and the LG OLED55C6P have local dimming technology with the number of dimming zones based on the number of pixels. It is understandable that the black level reached by them is perfect because the more dimming zones for local dimming, the more the black level reached is deeper. In addition to a deep black level, both the OLED55C6P and the OLED55B6P support color gamut. And although their peak brightness is not as bright as LED TVs, at least it is very bright for OLED TV and exceeds the minimum standardization HDR 10.

In addition to an amazing picture quality, both the LG OLED55C6P and the LG OLED55B6P come with an excellent smart TV platform called WebOS 3.0. It is a very attractive, intuitive, and responsive interface with useful apps provided. Of course this will add to your pleasure when enjoying 4K entertainment in your home.

LG OLED55C6P vs OLED55B6P Key Specs

The Differences between the LG OLED55C6P and the LG OLED55B6P

Type of Panel

We can see from the comparison table above, the major difference between the LG OLED55B6P and the LG OLED55C6P is their type of panel display. The LG OLED55C6P comes with a curved panel while the LG OLED55B6P comes with a flat panel. Of course it is like talking about the differences between a curved panel and a flat panel.  There are 4 points which detract from this difference: size and immersiveness, viewing Angle, aesthetics, and reflection. But because the OLED panel already delivers perfect viewing angle and reflections, there are only size and immersiveness and aesthetic which becomes their differences in these types of panel.  In terms of size immersivenes, although they have the same screen size, the picture displayed on the curved panel of the OLED55C6P looks slightly bigger than the OLED55B6P with the flat panel. This is caused because the curved panel has a bigger FOV (Field of View) than the flat panel. At a distance of 6 feet, the OLED55C6P’s curved 55” looks like a 55.8” screen. About the aesthetics, it doesn’t affect picture quality but only on the appearance because it seems more elegant.

3D Technology

The second major difference between the LG OLED55BC6P and the LG OLED55B6P is the 3D technology. The OLED55C6P comes with passive 3D technology while the OLED55B6P doesn’t come equipped with 3D technology. The 3D performance offered by the OLED55C6P is very good. 3D images displayed look very sharp and clear with tons of depth. Additionally there is also no crosstalk and no flickers so that it is comfortable for the eyes. The other benefit is that you can use any passive 3D glasses for the OLED55C6P. Passive 3D glasses are cheaper, lighter, more comfortable to use and batter-free. But as noted, passive 3D glasses allow the eyes to receive only half the number of lines of horizontal resolution.

Connectivity

The LG OLED55C6P is equipped with 3 HDMI Ports and the LG OLED55B6P is equipped with one more port having a total of 4 HDMI Ports for their major connectivity. In terms of input lag the LG OLED55C6P offers slightly lower input lags than the LG OLED55B6P on all input sources. This is helpful for viewing professional games especially for HDR games that need low input lag, and the LG OLED55C6P offers better performance than the LG OLED55B6P. In addition to the HDMI Ports, both are also equipped with 3 USB ports (2 ports are 2.0 version and 1 port is 3.0). Additionally, there’s also a Composite IN (AV), Component In, Ethernet port, Digital Audio Out (Optical) and RF in (Tuner) where the number of each is 1. The other difference is where the ports are located. On the LG OLED55B6P, the HDMI 1, HDMI 2, USB 1 and USB 2 ports are all installed at the side of the panel where the other ports are located on the rear panel. Meanwhile on the LG OLED55C6P, all the HDMI ports and USB Ports are located at the side panel while the others ports are installed at the rear panel.

Similarities

Except for the above, the LG OLED55B6P and the LG OLED55C6P offer virtually identical performance and features, whether it is about picture quality, motion handling, UHD Up-scaling, Smart TV, and even sound quality.

Picture Quality

As mentioned above, picture quality is the main reason why we choose OLED TV. Just like the other series of LG’s OLED TVs, OLED technology offers the best picture quality for 2016 and beyond. The main component of amazing picture quality produced by these is their perfect black level where no LED TVs can achieve. Because the black level reached by both is 0 nits, this allows both to have an infinite native contrast ratio. As we know, contrast ratio is the ratio of the white brightness divided by the blacks. And contrast ratio is the best indicator to know how good the picture produced. With 0 nits of black level, both the LG OLED55C6P and the LG OLED65B6P can display HDR10 and Dolby Vision contents without any issue at black level. For displaying them fully, HDR 10 needs 0.0005 nits of black level and Dolby Vision need 0 nits of black level for exploiting the detail of images in shadows or dark scenes.

Additionally the other important component of HDR is peak brightness. As the standardization, HDR 10 needs at least 550 nits of peak brightness while Dolby Vision needs at least 10000 nits with the current target being 4000 nits of peak brightness. What is achieved by both the LG OLED55B6P and the LG OLED55B6P about peak brightness is a very bright range for OLED TVs. The LG OLED55B6P can reach about 780 nits of peak brightness on a 10 % window while the LG OLED55C6P can reach about 650 nits of peak brightness on the same 10% window. This means that peak brightness reached by them exceeds the minimum standardization required for displaying HDR 10 fully. Unlike a baack level where OLED TV is the best, this is not the brightest peak brightness reached by a TV.  Samsung’s 2016 UHD TV lineup or the Sony X930D/ 940D and Z9D even can reach more than 1000 nits of peak brightness. Even so, peak brightness reached by them meets the minimum standard for HDR10. Combine to infinite contrast reached by them, both HDR 10 and Dolby vision picture displayed on each of their screens will look absolutely amazing despite theoretically, their peak brightness is not quite bright t display Dolby Vision Contents fully.

For color performance, both the LG OLED55B6P and the LG OLED55C6P support wide color gamut. With 4 sub-pixel technology by adding white sub-pixel to standard RGB sub-pixels, both can reach about 96% of DCI P3 color space. The minimum color coverage required for displaying HDR 10 fully is 90% of DCI P3 color space while Dolby Vision needs Rec.2020 color coverage. This means that there are no issues on color gamut when they are displaying HDR 10 contents. Additionally the color gamut delivered by them is also equivalent to 74% of Rec.2010 color coverage. Although it is still not enough to cover all color coverage required for displaying Dolby Vision fully, but at least for displaying Dolby Vision, it is quite good.

One more parameter required by HDR is about the depth of color. This has to do with the color gradient of the picture produced. HDR 10 requires 10 depths of color while Dolby Vision requires 12 bit depth of color. And both the LG OLED55C6P and the LG OLED55B6P support 10 bit color depth and this means they can deliver about 1.07 billion shades of color. The result is a color gradient of the picture when they are displaying HDR contents that look very smooth without color banding and gradation.

The combination of deep black level, bright whites, and wide color gamut makes the HDR picture produced by each of them look very amazing, even for HDR 10, and they are compliant with the Ultra HD Premium Certification set by UHD Alliance. This mean when they are displaying HDR 10 contents, the picture displayed looks absolutely amazing without any issue. Additionally although in some aspects, what is reached by the LG OLED55B6P and the LG OLED55C6P is still not enough to meet the minimum standardization of Dolby Vision, at least Dolby vision contents that re displayed on the screen still look amazing and are among the best compared to the other series of LG’s 2016 OLED TV lineup.

UHD Up-scaling

Although it is still below the upscaling abilities of the Sony 4K TVS (those are the best,) the UHD Up-scaling performance of the LG OLED55B6P and the LG OLED55C6P is also very good.  No matter the resolution of the video sources, they will be displayed in 4K quality sharply and clearly at the screen of both. 1080p videos like Blu-Ray Movies displayed sharply in 4K quality without small details missing. Additionally, even 720p content like movies from HDTV it also still looks sharp once up-scaled and small details are also still visible.  Even for 480p contents like DVDs, they are up-scaled to 4K quality very well. Straight lines in images don’t look choppy at all. Of course this is very useful to play your old contents which have lower resolution than 4K. Additionally most of the contents that are available in the market still have lower resolution than 4K, so a great performance enhancing UHD Up-scaling engine for 4K TVs is still required.

Motion Handling

Their ability when handling motion blur is similar. Pixel response time of both is excellent and is about 0.1ms. This is quite quick to display fast contents like sports programs or fast movies without adding motion blur. It is perfect for a TV. When playing 24p contents like Blu-Ray movies, they also show the same golden performance that means there is no judder. But when they are playing 24p via 60p signals, their performance is less than maximal. The judder cannot be removed completely. A different performance by them is indicated when they are playing 24 contents via 60i signal like satellite or Cable TV. For this case, the LG OLED55C6P offers better performance than the LG OLED55B6P. This means that the LG OLED55C6P offers a judder-free picture while the LG OLED55B6P doesn’t.  Because most people don’t notice judder, usually we can ignore this difference.

Smart TV

Smart TV is another excellent feature offered by both the LG OLED55B6P and the LG OLED55C6P. With WebOS 3.0 as the platform, they offer a very attractive and responsive smart TV platform. The user interface is designed to be simple and intuitive, which becomes a part of the distinctive charm of WebOS. The most useful and popular apps are organized on “Strip Bar” at the bottom across the screen so you can easily select and launch an app. The booting time (load in time of an app) and selecting between apps is also very quick, which makes it more comfortable when operating it. For pampering you when enjoying Smart TV on the screen of your LG OLED55B6P and LG OLED55CP, there are a lot of the most popular and useful apps like Netflix, YouTube, Hulu Plus, Spotify, Amazon Prime and more. Even some of them already support HDR 10 and Dolby Vision and allow you to stream them directly. The other apps  provided are WebOS Browser, LG Contents Store, and many more. The new features are Magic Zoom and Magic Mobile connection.

For the controller, both the LG OLED55B6P and the LG OLED55C6P are equipped with LG’s magic remote. The most useful function provided is “Point and Click” which is similar in function to a mouse on a computer.   This is very useful when you are surfing the internet, inputting text, and more. The other interesting function is Voice Navigation that allows you to control TV functions with voice commands. This means there is a built microphone in the remote.

Sound quality

As to their audio system, both are equipped with a 4.0 channel speaker system with 40 watts total power speaker system. Their sound system is designed by Harman Kardon, a big name for premium audio systems. But unfortunately, there is no built-in woofer. This can be ascertained in that low frequency or bass performance for both of them is poor. Even so, frequency response on both is very good to make their sound quality above average. A small issue found at higher volume, the sound heard is slightly compressed. For most people, the sound quality offered by the LG OLED55C6P and the LG OLED55B6P might be quite good but for those purists who care about sound quality, the addition of an external sound bar is highly recommended.

Conclusion

As we have discussed above, the type of panel, the 3D technology and the number of HDMI ports are the main differences between these LG models. None of these have a major impact on picture quality although the difference in 3D technology is very clear. The other slight difference between them is the peak brightness reached by them where the LG OLED55B6P can reach a slightly brighter peak brightness than the LG OLED55C6P. Overall the picture quality produced by them is virtually identical.

So which is a better choice for you? As discussed above, the LG OLED55C6P is superior on 3D technology while the LG OLED55B6P is superior on the number of HDMI Ports. In term of type of viewing panel, some people might prefer the aesthetic of a curved panel, but for some people, they prefer a flat panel. While there are differences between them for some other aspects such as 24p handling and input lag, the differences are not very significant. Now the decision is yours based on your preferences.
