LG OLED C8 vs OLED C7 Review (C7P vs C8PUA, OLED55C8PUA vs OLED55C7P, OLED65C8PUA vs OLED65C7P)
LG OLED C8 or C8PUA is a mid-range model of LG’s 2018 4K HDR OLED TV lineup. It is a successor of LG OLED C7 that becomes one of the best seller TVs in 2017. Unlike the predecessor OLED C7 that comes with 2 screen size options only (55 inch and 65 inch), now, in addition to 55 inch (OLED55C8PUA) and 65 inch (OLED65C8PUA), OLED C8 also comes with the largest screen 77 inch (OLED77C7PUA). This is certainly as good news for you who want bigger screen OLED TV with more affordable price. Since the screen sizes which available on both are 55 inch and 65 inch only, this comparison certainly is also as true to these sizes only (OLED55C7P vs OLED55C8PUA and OLED65C7P vs OLED65C8PUA). With the same screen size, OLED C8 is priced hundreds to more than a thousand dollar more expensive than OLED C7, and of course this is a striking difference in price. Nevertheless, this is more caused OLED C7 is a last year model and its prices have dropped a lot. Otherwise, since OLED C8 is recently released, its price certainly is still high. But of course, their prices certainly are not fixed and could still change at any time, especially for the price of OLED C8PUA. So, what additional features and technologies offered by C8 and how is its performance compared to the predecessor C7?

Features and Technology of LG OLED C7 and OLED C8
One of the major changes brought by OLED C8 than the predecessor OLED C7 is picture engine. Now, OLED C8 is powered by Alpha 9 Intelligent processor that uses a four-step artefacting prevention algorithm where it is claimed bring some improvement in processing HDR images, particularly in handling motion artefacts and also optimizing its color gradient so minimizing the issue with color banding which becomes an issue of its predecessor OLED C7. Additionally, LG OLED C8 also brings some improvements on its smart TV platform. Still featuring WebOS as its smart TV platform, now the WebOS comes with LG’s AI (Artificial Intelligence) ThinQ that acts as a hub for connected smart devices. It is a built-in smart assistant like Samsung’s Bixby Voice Assistant on Samsung’s TV or Google’s Voice Assistant on Sony’s TV that can parse complex voice command. Not just that, AI ThinQ also can intelligently maximize picture and audio settings based on the currently selected input. Additionally, AI ThinQ can also be integrated with other smart assistant like Google Assistant or Amazon Alexa platform. Meanwhile, the other improvements brought OLED C8 are about the level of their True Color Accuracy and Ultra Luminance technology where with Pro version, it offers a bit enhancement on colors rendition and peak brightness than LG OLED C7. Additionally, there are still some changes and improvements brought by LG OLED C8 over OLED C7 like the design of their stand or others, but they are not too major.
On their panel, there are not a lot of changes. Both LG OLED C7 and OLED C8 equally use OLED Panel with 4 sub- pixels RGBW. As we know, OLED Panel offer some advantages than LED panel like infinite native contrast ratio which allow them to deliver perfect black, excellent pixel response time to deliver smooth fast paced images, and extremely wide side viewing angle coverage to deliver consistent picture quality when viewed from any angle. For maximizing their color reproduction, in addition to their panel uses 4 sub-pixels (RGBW), there is also a feature called “Tru Color Accuracy” behind them. But as we have mentioned, OLED C8 use Pro version while OLED C7 use standard version. Additionally, on brightness enhancement technology, both of them are also equally powered by Ultra Luminance technology. Also as we have mentioned, for this case, OLED C8 use pro version that allows it can do better in improving the brightness than OLED C7 that uses standard version. Coming with HDR, both LG OLED C8 and OLED C7 already supports most of HDR formats which available in the market including Dolby Vision, HDR 10, HLG (Hybrid Log Gamma) and also Advanced HDR by Technicolor. This allows you to enjoy your favorite movies with more HDR format options.
Meanwhile, for connecting with other devices, both of them are also equipped with similar inputs/outputs. There are 4 HDMI ports as their major connectivity, 3 USB ports, 1 Composite In, and others. This allows you to connect most of your electronic devices to OLED C7 or C8 at once. And for delivering impressive sound quality, both of them equally equipped with 2.2 channel speaker system with built-in subwoofer and 40 watts of total sound output. The interesting, both of them already support Dolby Atmos and with their 2.2 channel speaker system, this allows you to enjoy Dolby Atmos sound experience without additional external sound system.
LG OLED C8 vs OLED C7 Performance
Overall, LG OLED C8 and OLED C7 have excellent picture quality. They have infinitive contrast ratio, perfect black level and perfect black uniformity, bright peak brightness and good reflection handling, wide color gamut and excellent color gradient, excellent side viewing angle coverage, and strong performance of some other aspects. All of them certainly make the picture displayed on their screen looks excellent, no matter they are playing SDR or HDR images, set in a dark room or bright room, and the angle you are watching from. But even so, as a newer model that also powered by new processor called Alpha 9 Intelligence, LG OLED C8 bring some improvement than the predecessor OLED C7, particularly on their peak brightness and color gradient. However, this doesn’t mean they don’t have bad point. One of the major issues of OLED TV including OLED C8 and OLED C7 is about their bad image retentions. You probably will find out the images retention after they show static scene over a long time like after playing video games and this may be at risk to permanent burn-in. But don’t worry, they have a feature named “Pixel Refresher” under “OLED Panel Setting” that will help you to get rid the image retention that might visible.
Native Contrast Ratio and Black Level
As we know, one of the major excellence of OLED panel is it can deliver infinitive native contrast ratio and perfect black level. And since both LG OLED C8 and OLED C7 use OLED Panel, this certainly also makes both of them have infinite native contrast ratio and perfect black. Additionally, since it doesn’t use backlight and its pixel can switch on/off/dim individually, this also makes its black uniformity is also perfect. The result, dark scenes of non HDR images can be shown excellently on their screen, even when set in dark environment. As we know, to show dark scene of images in a dark room excellently, this requires high native contrast ratio of a TV. Meanwhile, coming with HDR technology, both LG OLED C7 and OLED C8 are required to be able to reveal more information in shadow or dark scene of HDR image where to do that like the intended, a HDR TV must have a very deep black level. As the example, for HDR 10 format, to show shadow details of HDR 10 images like the intended, a TV must have 0.05 nits of black level or darker while Dolby Vision need much darker black level. With close to 0 nits of black level, to show shadow details of HDR images like the intended, no matter the format of HDR videos, this certainly is not a difficult job for both OLED C8 and OLED C7. The result, no matter the format of HDR image, shadow details can be shown excellently on the screen of OLED C7 and OLED C8. This certainly makes them great to be used for watching movies with a lot of dark scenes like Horror or Sci-Fi movie.
When inputted by SDR source, both LG OLED C8 and OLED C7 have similar peak brightness and essentially, their peak brightness is quite bright to overcome the glare. On the other hand, both LG OLED C7 and OLED G8 also do a great in handling reflection. The result, as long as there are no light or sunlight strikes directly onto the screen, in a bright room, the picture displayed on their screen looks remains well. While their peak brightness is almost similar when inputted by SDR signals, when inputted by HDR signals, their performance is not similar. This might be caused by the different level of their Ultra Luminance technology. As we have mentioned, LG OLED C8 is supported by Ultra Luminance pro version while OLED C7 is supported by Ultra Luminance standard version. The result, OLED C8 can reach more than 900 nits at small windows size, while peak brightness reached by OLED C7 at the same small window size is about 700 nits. Both of them might not be able to show highlight of HDR images at 1000 – 4000 nits of brightness range where HDR images are usually mastered, but for OLED TV, what offered by the can be said excellent. They even can show highlight of HDR images brighter than 550 nits as the minimum recommendation set by UHD alliance to show highlight of HDR 10 images like the intended. Additionally, since each their pixel can switch on/off/dim individually without affected by the condition of surrounding pixels, makes there is almost no “blooming” around a small bright object. But since it has Auto Bright Limiter (ABL) that will limit their peak brightness at large window size, when they are showing a scene with all objects are bright or large bright scene, the picture displayed on their screen will look dim.
Discussing about their color reproduction, the color gamut of LG OLED C8 and C7 is nearly identical. Although not as excellent as Samsung’s 2017 QLED TV, essentially, their color gamut is also excellent and only a bit worse than Samsung QLED TV. Nearly all colors of HDR images in DCI P3 can be shown fairly accurate, even for deep greens where most of modern TV has an issue to show these colors fairly accurate. Additionally, their color gamut is also able to cover colors in Rec.2020 fairly well, makes color of Dolby Vision images displayed on their screen looks fairly accurate. Additionally, both LG OLED C7 and OLED C8 also have almost identical color volume. Both of them can show their wide color gamut at dark and moderately bright colors fairly well. A bit unfortunate, when showing extremely bright colors like colors in highlights of HDR images, they cannot show these colors as good as darker colors. Nevertheless, overall their color reproduction is excellent and not many TVs which able to match its performance.
As we have mentioned, the use of Alpha 9 processor makes LG OLED C8 has better color gradient than OLED C7. Nevertheless, essentially, LG OLED C7 already has excellent color gradient. When showing 10 bit images like HDR videos, OLED C7 is actually able to show them smoothly without any major imperfection. Some little imperfections are only visible on dark part of grey scale and darker shades of colors and this should not be a serious problem for normal content. Meanwhile, with Alpha 9 processor, OLED C8 can show color gradient of 10 bit images much better. Its performance might not be perfect and some little color banding still visible at certain scene, but it is able to significantly reduce color imperfections which notice on the screen of OLED C7. The result, when viewed closely, color gradient of HDR images displayed on the screen of OLED C8 looks smoother than OLED C7.
Side Viewing Angle
Side viewing angle coverage of LG OLED C8 and OLED C7 is excellent, far better than what offered by LED TV with IPS panel. Black level and brightness of the picture displayed on their screen looks consistent, even when viewed from extremely side angle. Color might still look shift started at about 30 degrees off center and front, but at wider angle, the color shift is not as bad as LED TV. Nevertheless, except viewed from extremely side angle, the color s shift will be not too noticeable. This means, except viewed from extremely side angles, the picture displayed on their screen will looks remain amazing. This certainly makes both of them as a great TV when used in a wider room where there is a group of viewers watch TV from multiple angles.
Motion Handling and 24p Playback
The other excellence offered by OLED TVs including LG OLED C7 and C8 is about its extremely low pixel response time, much lower than the lowest reached by LED TV. On the other hand, since OLED panel doesn’t have backlight, this allows there is no flicker when they dim the screen. Combination extremely low pixel response time and flicker-free of course makes their performance in handling motion blur is awesome. The result, when playing fast moving images like sports, fast movies or others, the picture displayed on their screen looks smooth with virtually no motion blur. Coming with Alpha 9 processor, OLED C8 bring an improvement in handling motion blur where it now has an optional BFI (Black Frame Insertion) to minimize the blur. By enabling BFI Mode (Set “Motion Pro” to on), this allow you to reduce the blur by adding flicker. For this case, LG OLED C7 has not this feature.
Meanwhile, when processing 24p movies, the excepting of 24p contents via 60i signals like movies from satellite TV, both of them equally can do a great job. This means, whether it is native 24p videos like Blu-Ray, DVD movies or movies from streaming apps like Netflix, Amazon Videos, and others, 24p videos via 60p signal like movies from streaming device such as Fire TV, Apple TV, and others, all of them can be shown clearly and smoothly with judder-free on their screen. While for 24p videos via 60i signal, for this case, LG OLED C7 can show it with judder-free while OLED C8 cannot. Nevertheless, although for this now, OLED C8 cannot remove the judder for 24p movies via 60i signals, usually, in future, there will be update software that will overcome this issue. In the second place, since most people don’t sensitive to judder, this should not be a problem for most people.
Both LG OLED C7 and OLED C8 equally equipped with 4 HDMI ports as their major connectivity. All of their HDMI ports already support HDMI 2.0 Full Bandwidth, HDCP 2.2, and also CEC, while that supports ARC (Audio Return Channel) is only HDMI 2. Additionally, they are also equally equipped with 3 USB ports. The difference, all of USB ports of OLED C8 are USB 2.0 while for OLED C7, 2 ports are USB 2.0 (USB 2 and 3) while 1 port is USB 3.0 (USB 1). In addition to USB ports, there are also equally equipped 1 Composite In (AV In), 1 RF In (Terrestrial), 1 Ethernet, and 1 Digital Audio Out (Optical). Additionally, they are not also equally equipped with Component In.
Meanwhile, both of them are also equally have excellent input lags in “Game Mode” and “PC Mode”. With less than 25 ms of input lags at 1080p and 4K inputs, this certainly makes the very comfortable when used for games. No matter the games you are playing, whether it is casual or fast paced games, this will feel responsively. But as the note, although both LG OLED C7 and OLED C8 are great TVS for games, since most of games has static image and on the other hand, both LG OLED C8 and C7 has bad images retention, play games over a long time should be avoided.
As their smart TV platform, both of them are equally featuring WebOS, one of the most simple but attractive smart TV platform. For this case, LG OLED C7 comes with version 3.5 while OLED C8 comes with a newer version that is version 4.0. In term of User interface of their home screen, there are not many changes. At the bottom of the screen, there are a “strip bar” contains “tiles” as the quick access to many most popular apps, settings, and inputs. This allows you to navigate easily and quickly. A bit differences, in addition to there are quick access icons for “multimedia”, “music”, and “setting” on the top right of the screen, on a newer version, there is also quick access icon for search function, allows you to search thing easily and quickly. A bit improvement brought by version 4.0 is about its performance where with a newer processor, this make the menu more responsive than the older version. Meanwhile, talking about their apps, there are a lot pre-installed apps provided such as YouTube, Netflix, Amazon Videos, Live TV, Web Browser, and many more. Additionally, although not as many as what provided by “Google Android TV” or “Samsung Apps Store”, WebOS also has an apps store name “LG Apps Store” that also provides tons of interesting and useful apps, contents, information, and games. A major new feature offered by newer version, it comes with LG AI ThinQ that makes its voice navigation can do a lot more functions. Additionally, ThinQ is also ready to support Amazon Alexa and Google Home Assistant.
As their controller, both LG OLED C8 and OLED C7 are equally equipped with LG Magic Remote. At a glance, they look similar, but if we observe more carefully, there are some little changes on the text of their buttons. Nevertheless, this is not important thing that has an impact on their performance. In addition to the standard buttons like “number buttons”, power buttons”, “common function button” and others, both of these remotes are also equally equipped with two dedicated buttons for Netflix and Amazon, allow you to launch these apps without entering the menus. At the center of their direction buttons, there is also a clickable “scroll wheel”, allow you to scroll the highlighted menus and select them by clicking it. The excellence, you can also move the pointers at the screen by moving the remote and the pointers will follow the remote’s movement, allow you to point and select thing directly. Combined to the function of their “scroll wheel” this allows you to navigate easily and quickly. Meanwhile, both of them might be equally equipped with built-in microphone and have voice navigation functions, but with already support LG AI ThinQ, remote of OLED C8 can do a lot more voice commands than OLED C7. On the OLED C7, with voice commands, you can only search contents only, While On OLED C8, with voice command, you can do a lot like search something, change some setting, change inputs, even talk about the weather at this time.
|Performance||LG OLED C8||LG OLED C7|
Essentially, OLED TV including LG OLED C7 and OLED C8 have excellent picture quality. Infinite contrast, perfect black level and uniformity, excellent color reproductions, extremely wide color gamut, excellent motion handling, and great performance of other aspects, all of them make the excellence of both in picture quality is undoubtedly. No matter they are set in a dark or bright environment, play SDR or HDR contents, viewed from the front and center or the side, the picture displayed on their screen looks remain excellent. Additionally, great performance of some other aspects like excellent motion handling and 24p playback, low input lags, and other make them as great TV for any usage, whether you use them for watching TV shows, movies, sports, playing games, and more. Meanwhile, coming with HDR, it supports most of HDR formats which available and their performance is also great, allows you to enjoy your favorites movies with more HDR formats options.
The only major issue of OLED C8 and OLED C7 is about their bad images retention that makes them have a risk to permanent burn-in. But even so, as long as you don’t often play contents with static images over long times like play games for a long time, this should not be a problem. A bit shortcoming, although for OLED TV their peak brightness can be said excellent, but their peak brightness is still below 1000 nits. This means, they are not able to show highlight images at 1000-4000 nits where HDR images are usually mastered.
As we have discussed a lot above, LG OLED C8 as a newer model brings some improvements and additional features makes its performance is better than the predecessor OLED C7. The improvement in picture quality offered is about peak brightness, color gradient, and motion handling makes picture displayed on the screen of OLED C8 looks a bit better than OLED C7, particularly when displaying HDR images. Additionally, the most attractive new feature offered by OLED C8 is about LG AI ThinQ, makes its voice command can do a lot of more than OLED C7. While some other improvement offered by OLED C8 like input lag or other don’t have a striking impact due LG OLED C7 also already have excellent picture quality and performance.
So, which is a better choice between them? As we have mentioned, with the same screen size and some improvements offered, OLED C8 is priced hundreds even more than thousand dollars more expensive than OLED C7. But this is more caused the price of OLED C7 has dropped a lot due its existence has been replaced by OLED C8. Now the decision certainly comes back to you according to your preference and budget. If you don’t mind to spend hundreds dollar more to get a newer model and some advantages offered, LG OLED C8 might be a good option for you. But if you have limited budget, LG OLED C7 might be a good alternative for you. But keep in mind, since OLED C8 is recently launched that certainly makes its price is still high, will be better if you wait for a few time until its price goes down. On the other hand, if you want to buy OLED C7, since its existence has been replaced by OLED C8 and it has been discontinued by the manufacture, you should buy it immediately before it runs out of stock.
