Our Verdict
Excellent TV for a wide range of usages. The LG 55C8PUA has perfect blacks, resulting in excellent dark room performance. The TV handles motion extremely well due to the instantaneous response time and ability to flicker the image at 60Hz to clear up motion. The picture also remains accurate at an angle, which is great for those with wide seating. Reflection handling is excellent for rooms with lights or glare on the screen.
- Can produce perfectly deep and uniform blacks
- Instantaneous response time
- Image is accurate when viewed at an angle
- May be a risk of permanent burn-in (see here)
- Brightness changes with screen content (ABL)
Excellent choice for watching movies in a dark room. Perfect blacks result in deep and detailed dark scenes. The TV can display most content without judder, but some stutter is visible due to the low frame rate of movies - especially for wide panning shots.
Great choice for watching TV in a bright room. Reflection handling is excellent, which is great for rooms with lights or glare on the screen. The TV also has a good brightness to overcome ambient light. The WebOS smart platform works well for casual browsing or watching content on Netflix. For regular watchers of channels with a lot of static content, there may be a risk of burn-in though (see here).
Excellent for sports fans. Motion handling is excellent due to the instantaneous response time and ability to flicker the image to clear up motion. Dirty screen effect is also not an issue, as the screen is very uniform. Picture quality is also excellent, and remains accurate when viewed at an angle which is great for large numbers of people to watch an important game.
Excellent TV for gamers. Input lag is very low, so the TV feels very responsive. Motion handling is excellent due to the instantaneous response time and ability to flicker the image to clear up motion. Picture quality is also excellent due to the perfect blacks.
Excellent for watching HDR movies in a dark room. Picture quality is excellent due to the perfect blacks and impressive uniformity. The LG 55C8 can produce very bright highlights in real scenes and also produces saturated colors, to make HDR pop. The fast response time does result in some stutter, especially when viewing movies in long panning shots.
Impressive HDR gaming performance. Input lag is very low, so the TV feels responsive with HDR. Motion handling is excellent due to the instantaneous response time and ability to flicker the image and clear up motion. Picture quality is also excellent, and the TV can make HDR scenes pop due to the high peak brightness of highlights and ability to produce very deep colors. For people who play games with a lot of static content there may be a risk of burn-in though (see here).
Great choice for PC use. Image remains accurate when viewed at an angle so the sides of the screen are uniform. Supports chroma 4:4:4 for clear text across all backgrounds. Also, the LG C8P supports a 1080p @ 120Hz input for those who want the most fluid experience. Motion handling is excellent, due to the instantaneous response time. Unfortunately the brightness of the screen changes depending on the content and areas of static content may have a risk of burn-in (see here)

Differences Between Sizes And Variants
We tested the 55" model (OLED55C8PUA). For the most part, we expect our review to be valid for the 65" (OLED65C8PUA) and 77" model (OLED77C8PUA).
If someone comes across a different type of panel or if their LG OLED 55C8PUA doesn't correspond to our review, let us know and we will update the review. Note that due to variances between panels some results such as gray uniformity and image retention may vary between individual units.
| Size | US Model | EU Model |
| 55" | OLED55C8PUA | OLED55C8PLA |
| 65" | OLED65C8PUA | OLED65C8PLA |

Update 12/11/2018: We have received a few notes that the 77'' model makes a hissing sound. If you experience this, we suggest that you contact LG.
Popular TV Comparisons
The LG C8P offers excellent performance across the board. However, it isn't perfect and comes at a high price. Check out some of our comparisons below for different recommendations depending on your usage. See also our recommendations for the best TVs and the best OLED TVs.
The LG C8 OLED and the LG CX OLED are very similar TVs. Their OLED panels allow them to individually turn off pixels, resulting in an infinite contrast ratio and perfect black uniformity. Picture quality between each are similar, and the real differences are that the CX has HDMI 2.1 support, allowing it to support 4k @ 120Hz. It also has VRR support to reduce screen tearing, which the C8 doesn't have.
The LG C2 OLED is a lot better than the LG C8 OLED. There's not much difference in picture quality: they both display deep, uniform blacks in a dark room with no blooming around bright objects. The C2 is a lot brighter, especially in HDR, so bright highlights stand out much better. The C2 also has more advanced gaming features, including variable refresh rate support to reduce screen-tearing.
The LG C8 OLED is very similar to the LG B8 OLED for mixed usage. The C8 offers performance in the same ballpark, and the small differences between the two TVs could be due to panel variance. The C8 has the newer Alpha 9 processor, whereas the B8 still carries the Alpha 7 processor, but we did not see a significant difference in performance.
The LG C8 OLED is somewhat better than the LG B7/B7A OLED. While the overall performance of the two is very similar, the LG C8 has an optional Black Frame Insertion feature that the B7A doesn't have. This feature helps to improve the perceived clarity of motion on the C8, at the expense of some brightness.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
