Technologies and Features of LG OLED C8

Coming as the successor of OLED C7, LG OLED VC8 bring some improvements and new features over the predecessor. The major change brought by OLED C8 is on its picture engine where it is powered by Alpha 9 Intelligent processor. Not just improve the picture quality, Alpha 9 also act as the main brain of OLED C8 in controlling almost all of its features including WebOS 4.0 and LG AI ThinQ, a home intelligence system by LG. It is a new feature that bring by OLED C8 over the predecessor OLED C7 that allows you to interact with other ThinQ compatible devices or even Google Home or Amazon Alexa Devices with your voice commands.

Still optimized for HDR, LG OLEC C8 already supports most of HDR format which available in the market including HDR 10 by UHD alliance, Dolby Vision by Dolby Laboratories, Advanced HDR by Technicolor, and HLG (Hybrid Log Gamma) by NHK and BBC. Meanwhile, as we know, uses OLED panel makes it has infinite contrast ratio and perfect black level, where this becomes the major excellence of OLED C8. Additionally, with 4 sub-pixels RGBW technology that optimized by True Color Accuracy Pro, this allows OLED C8 can deliver excellent color gamut. Even not just that, Alpha 9 processor behind it also helps to improve its color gradient so looks better and smoother than the predecessor OLED C7. And for maximizing its peak brightness, OLED C8 is powered by Ultra Luminance Pro technology, make it is able to produce bright peak luminance.

The other advantages that offered by LG OLED C8 with its OLED panel is its extremely low pixel response time that allows it to deliver smooth picture quality with almost no motion blur. An additional feature brought by OLED C8 over the predecessor OLED C7, it now has Black Frame Insertion mode that help to reduce the blur when it is playing 60 fps contents like games, sports, and others. Meanwhile, like other models of LG’s 2018 4K HDR lineup, it is also equipped with 4 HDMI ports, 3 USB ports, and some other inputs/outputs that allows you connect most of your other devices on OLED C8 at once. And that is not less attractive is about its smart TV where with WebOS 4.0 with LG’s AI ThinQ as its smart TV platform, it offers simple but powerful smart TV experience in your home. And for delivering impressive sound quality when you are enjoying HDR experience, LG OLED C8 is equipped with 2.2 channel speaker system including Woofer with 40 watts of total sound output. Even not just that, it also already support Dolby Atmos, allow you to enjoy HDR entertainment with Dolby Atmos sound experience without adding external speaker system or sound bar.

Performance of LG OLED C8

Picture Quality

Native Contrast Ratio and Black Level

LG OLED Black Level

Native contrast ratio and black level become the major advantage offered by LG OLED C8. With OLED Panel that has self-lighting pixel where the light source is not from backlight but from the light of their pixels themselves, when displaying totally black, this allows the screen doesn’t emit light at all. This make depth of black level produced by OLED C8 is perfect and its black uniformity is also perfect. This certainly is great for everything related to the dark. The result, when showing dark scene, the picture displayed on its screen looks excellent, even when set in a dark room where the impact of high native contrast ratio is very sensitive.  Additionally, its perfect black produced by OLED C8 is also able to reveal more information in dark scene of HDR image, makes shadow details of HDR images looks excellent like the intended. With excellent performance in dark scene, this makes LG OLED C8 is a great TV when used to watch HDR movies with a lot of dark scene like horror or thriller movies, even when you are watching in a dark environment.

Peak Luminance

ultra luminance

While OLED C8 has infinite native contrast ratio and perfect black level, on the other hand, it also has excellent peak luminance. Its peak luminance might not able to match what produced by top model LED TV like Sony X930F or Samsung Q9F, but for OLED TV, it is really excellent, even still brighter than some upper middle model of LED TVs. When inputted by SDR signal, it has peak luminance more than 300 nits that mean it is quite bright to overcome the glare of ambient light when set in a bright room. Combined to its good reflection handling, this makes the picture look remain good and is not too dim when used to watch movies in a bright room. A bit unfortunate, its peak brightness will be slightly dimmed when it is showing a scene with all objects are bright. But overall, its peak brightness is fairly good when playing SDR contents.

Meanwhile, when playing SDR contents, LG OLED C8 even can reach brighter peak luminance, particularly for small windows size.  When showing small bright object like highlight of HDR images, OLED C8 even can show it at close to 1000 nits of peak brightness. This certainly makes a dramatic highlight of HDR images looks excellent on the screen of OLED C8. But a bit unfortunate, the larger a bright object, the peak brightness will dimmer and till when showing a scene with all object are bright, its peak brightness will look very dim, even dimmer than when it showing SDR images. However, because there is almost no scene with all objects are very bright, this should not be a problem when it used for watching movies. On the other hand, since its peak brightness is still less than 1000 nits while on the other hand, HDR images are usually mastered at 1000 – 4000 nits of brightness range, this certainly makes LG OLED C8 is not able to show highlight of HDR images as bright as the native brightness where they are mastered. This is still less powerful than what offered by Sony X930E in last year that was able to reach about 1500 nits of peak brightness. Nevertheless, for OLED TV, what offered by OLED C8 is including the bests. It even still can show highlight of HDR image like the intended particularly for HDR 10 images considering the standardization set by UHD alliance for OLED TV is only 550 nits, different to LED where the standardization set by UHD alliance is 1000 nits.

Color Reproduction

In term of color reproduction, LG OLED C8 also has excellent performance. Its color gamut coverage in DCI P3 is excellent, as well as in Rec.2020, it is also fairly good. Its color gamut coverage even is only a bit less than Samsung Q9F in last year as a TV with the best color gamut. With excellent color coverage in DCI P3, this certainly makes colors of HDR images that mastered in DCI P3 color space like HDR 10 images look very accurate, even for deep greens where most of TVs has an issue to show these colors fairly saturated. Additionally, its good color coverage in Rec.2020 also makes color of HDR picture that mastered in Rec.2020 color space like Dolby Vision images looks fairly accurate. Meanwhile, although not as good as Samsung QLED TV, color volume of LG OLED C8 is also fairly good. The excepting of extremely bright colors, overall, it can show its wide color gamut fairly well, even at extremely dark colors that most TVs usually have issue. But when showing very bright colors like highlight of HDR images or outdoor scene, the color might looks a bit less accurate. Additionally, coming with Alpha 9 processor, it makes LG OLED C9 is able to show color gradient of HDR images far smoother than the predecessor OLED C7. Some little bandings that visible on the screen of the predecessor can be significantly minimized on the screen of OLED C8. About color gradient, this is one positive impact caused by the use of Alpha 9 processor.

Side Viewing Angle

OLED TV Viewing angle

The other excellent performance offered by LG OLED C8 is about its side viewing angle coverage. Less than 30 degrees off center and front, color might start to look shift, but from wider angle, the color shift is not as significant as that happen on LED TV, even on IPS TV. Meanwhile, brightness and black level looks consistent from any angle, even when viewed from extremely side angle. The result, no matter from the angle you watch TV, you will get the same viewing experience. This certainly makes OLED C8 is as a great TV for you who often watch TV or play games with a group of your family or friends where they usually watch from multiple angles.

Motion Handling and 24p Playback

LG OLED TV Motion Handling

As we know, one of the main factors that has a big impact to the performance of a TV in handling motion blur is pixel response time. The lower pixel response time, the smoother the picture produced and the blur can be more minimized. Meanwhile, extremely low pixel response time is one of major excellence offered by a TV that uses OLED panel including LG OLED C8. Its pixel response time is extremely low, even far lower than 1 ms. As the comparison, the fastest response time reached by LED TV is still more than 1 ms. The result, when used for playing fast moving contents like sports or fast movies, the picture displayed on its screen looks very smooth, there is no visible trail following fast moving object. Additionally, since OLED C8 doesn’t have backlight, there is no flicker visible when it dims the screen makes the motion looks smoother that means it is great. But on the other hand, this will produce persistence blur. Started 2018, LG has add an option Black Frame Insertion mode on their OLED TV lineup including OLED C8. This is required to make the motion look clearer particularly when playing 60 fps contents like games, sports, etc. You can enable/disable this feature by turning on/off “Motion Pro” on its picture setting.

When playing 24p movies, LG OLED C8 also can do a good job. The excepting of 24p videos via 60i signals like movies from satellite TV, OLED C8 can show any source type of 24p videos clearly and smoothly with judder-free. This means, no matter it is native 24p videos like Blu Ray or DVD movies, 24p videos via 60p signals like movies from streaming devices, or  24p videos via streaming apps like Netflix, Amazon Videos, and others, all of them will be shown clearly and smoothly with judder-free on the screen of OLED C8. To remove the judder, you just need to turn on the “Real Cinema”, set “TruMotion” to “User” and set both “De-Blur” and “De-judder” to “0”. On the other hand, OLED C8 might not able to remove the judder when playing 24p videos via 60i signals, but usually there will a firmware update that will solve this issue.


Like middle to upper models of LG’s 2018 4K HDR TV lineup, LG OLED C8 is also equipped with 4 HDMI ports as its major connectivity. All of their HDMI ports already support HDCP 2.2, CEC, and HDMI 2.0 Full Bandwidth, while that support ARC (Audio Return Channel) is only HDMI 2. Additionally, there are also 3 USB ports. But unlike the predecessor OLED C7 where one of their USB port is USB 3.0, all of USB ports of OLED C8 are USB 2.0 and it doesn’t have USB 3.0. In addition to HDMI and USB ports, there are also 1 Composite In (AV) In, 1 RF In (Terrestrial), 1 Ethernet In, and 1 Digital Audio (Optical). Meanwhile, for wireless connectivity, it is equipped with built-in Wi-Fi 802.11 ac and Bluetooth. 3 HDMI ports and 1 USB ports are installed on side panel, while the others are installed on the rear panel.

OLED C8 Rear Panel

Overall, LG OLED C8 has excellent low input lags in PC Mode and Game. Its input lags at almost all of any source type are less than 25 ms that means it is great. Only in 4K HDR input at 60 Hz that might a bit higher, but it is still less than 30 ms that means it is still quite low to play any games so feels responsively. Combined to its excellent picture quality, good motion handling, and wide viewing angle, this certainly makes OLED C8 as a great TV when used for playing games. But as the note, since it has the possibility of experiencing permanent burn in, it is not recommended when often used to play games over long time.

Smart TV

WebOS 4.0

Like other models of LG’s 2018 4K TV lineup, LG OLED C8 is also featuring WebOS 4.0 as its smart TV Platform. There two important points that becomes the main highlight in this year. First, powered by Alpha 9 processor makes its performance is faster and more responsive than previous version. The second, It now features LG’s AI ThinQ that offers a more immersive smart experience.  Discussing about its WebOS, we certainly believe that it is one of the best smart TV platform with has simple navigation but powerful in performance and features. Its user interface is not many different to previous version, there is only a bit addition of search icon at the top right that allows you easier and quicker to access search functions. Meanwhile, at the bottom across the screen, there are still a group of “tiles” lined horizontally as the quick access to most popular apps, inputs and settings. Discussing of apps provided, there are a lot of interesting and useful pre-installed apps including VoD apps like Netflix, YouTube, Amazon Videos, Web browser, Live TV, games, some LG’s defaults smart features, and many more. Not satisfied with the default application? It also has LG’s apps store provides ton of downloadable apps, games, and other contents.

The interesting is about LG’s AI ThinQ that brought by WEBOS 4.0 that implemented through the voice commands. With this feature, you can interact with your other smart devices like Ovens, Laundry Machine, Dishwasher, and more through the voice commands of LG’s magic remote. Not even just that, it also already supports Amazon Alexa and Google Assistant compatible device that means you can also interact with smart devices which support them with its voice commands. Additionally, ThinQ also help its voice command can do more for TV functions or other features like check the weather, switch inputs, search on YouTube, and many more where you never get them in previous version.

LG Magic Remote 2018

As the controller, LG OLED C8 also comes with LG’s remote. As we have discussed a lot previously, this remote is excellent. The size of the remote is sufficient, not too large also not too small. In addition to standard buttons like “0-9” buttons, power button, direction button, menu button, and others, this remote also has two dedicated buttons for Amazon Videos and Netflix, allow you to launch these apps without entering the home menu. Additionally, in addition direction button, it also has a clickable “scroll wheel”, that allows you to scroll the highlighted item and select it with just click the wheel. Additionally, when the remote is pointed to TV, you can also move the cursor on the screen by moving the remote. And the other interesting thing which offered, this remote also can act as a universal remote, allow you to control some functions of other CEC compatible devices connected on OLED C8 via HDMI ports. And as we have discussed above, with ThinQ, its voice navigation work well not just on basic command, but also some advanced commands.
