Resolution : 4k

The LG C8 is a great 4k OLED TV with excellent picture quality. The emissive technology allows it to produce perfect blacks, which is excellent for dark rooms. The image also remains accurate when viewed at an angle, which is great for those with wide seating. It performs well with HDR content, as it can produce very bright and saturated highlights. The motion handling and input lag are also excellent, so it feels very responsive to gamers or PC users. It isn't perfect though, as the brightness changes depending on the screen content and static images shouldn't be shown for long on the TV due to temporary image retention and the risk of burn-in.

LG C8 Design Picture
Curved : No

The design of the LG 2018 C8 is excellent. The stand is wide but very sturdy and well built. The frame around the screen and stand are made of aluminum and seem well built. The stand is designed to help direct sound throughout the room, but due to its shape, it is not possible to place a soundbar directly in front of the TV. The TV is more uniform in color (black and dark gray) compared to the black and white design of the B7. Similar to other LG OLED TVs we have reviewed, there is only basic cable management.

Stand
LG C8 Stand Picture

The stand is wider than last year's C7, this time taking up nearly the full width of the TV, so it may be hard to fit on some tables. It supports the TV well and is very sturdy. It is made of aluminum with a hard plastic finish.

Footprint of the 55" TV stand: 35.0" x 9.2"

Back
LG C8 Back Picture
Wall Mount : Vesa 300x200

The rear of the LG C8PUA is very similar to the C7. Basic cable management, only a small removable cable guide as seen here. The 4 HDMI inputs face to the side, but the composite input is rear facing and may be difficult to access if the TV is wall mounted. The controls are located on the back to the side, similar to the C7.

Borders
LG C8 Borders Picture
Borders : 0.35" (0.9 cm)

The borders of the LG C8P are very thin and look very good. There is almost no gap between the border and the first row of pixels.

Thickness

Max Thickness : 1.89" (4.8 cm)

The top half of the screen is exceptionally thin, comparable to last year's C7. The bottom half houses the electronics and is thin and it sits flush to a wall when mounted

9.0 Build Quality
LG C8 Build quality picture

The overall build quality is excellent. The TV is solid and there were no obvious build issues or gaps. Care should be taken when moving the TV as the top is very thin.

Excellent picture quality on the LG OLED C8. The infinite contrast ratio delivers perfect blacks, making this an excellent TV for watching movies in a dark room. The good wide viewing angle and excellent reflection handling make this an excellent TV even for large, bright rooms. HDR highlights are very bright and stand out. The wide color gamut makes colors pop in HDR, and the pre-calibrated levels are good enough for most viewers. Excellent gray and black uniformity, the OLED C8P is an excellent TV for Sports.

Good SDR peak brightness on the C8P, almost identical to last year's C7. Real scene brightness is bright enough for most rooms. Highlights do not stand out in SDR. The TV remains consistent at ~350 cd/m² except when showing a large bright scene, like our 100% test window, where the screen dims significantly due to the Automatic Brightness Limiter(ABL).

With an 'OLED Light' setting of 40 or less, the fluctuations between scenes due to ABL drops to 20 cd/m² or less.

The LG C8 displays our test gradient smoothly with no significant banding. In certain scenes there is some banding noticeable in large areas of similar color. This can be reduced by enabling 'MPEG Noise Reduction', which toggles the gradient smoothing feature of the C8. This reduces the visible banding but also results in a loss of fine detail.

This test is only indicative of short term image retention and not the permanent burn-in that may occur with a longer exposure to static images. We are currently running a test to help us better understand permanent burn-in. You can read about our investigation into this here.

The 2018 LG C8 handles motion extremely well. The near instantaneous response time is excellent for watching sports or playing video games, as there is no ghosting or trailing during fast motion. Also, there is no visible flicker since there is no traditional backlight on OLED TVs, unlike Samsung's QLED technology. One downside to OLED technology is that there is some stutter when playing low frame rate content, especially when watching movies or TV Shows.

Like all OLED TVs, the response time is nearly perfect.

The TV uses motion interpolation (commonly known as the Soap Opera Effect) to artificially increase the frame rate of lower fps content up to a much smoother 120 fps. Motion Interpolation can look strange to many people, and it creates artifacts. In scenes with a lot of motion, the C8 stops interpolating the extra frames to avoid creating artifacts, preferring accuracy over smooth motion.

To enable this feature when watching lower frame rate content, set 'TrueMotion' to 'User' and adjust the 'De-Judder' slider for low frame rate content (such as 30 fps), and the 'De-Blur' sliders for 60 fps content.

The C8 is consistently able to remove judder from native 24 fps content, whether that content is played from the native apps or external sources such as a Blu-ray player. It can also remove judder consistently from 60 fps progressive scan content, but is inconsistent with interlaced content. Some judder may be visible when watching interlaced movies.

To enable this feature when playing 24p content from an external player, the 'Real Cinema' option must be turned on, and 'TrueMotion' must be set to 'User' with both the 'De-Judder' and 'De-Blur' sliders set to zero.

Note: We will retest 24p Judder when the next firmware update is released as this result is unexpected.

Very good low input lag, similar to the C7P. In game mode, the input lag is very low regardless of resolution, and outside of game mode the input lag is lower at 4k than the C7, and is one of the lowest we have ever tested.

The input lag was slightly higher in 4k @ 60 Hz + HDR. This result is highly unusual and has been retested to verify the results. The input lag is still low, and should feel very responsive.

Most of the common input resolutions are displayed properly without any issues. The C8 does not support 1440p resolution. When connecting to a PC, the HDMI input must have its icon changed to 'PC'. 4k @ 60 Hz @ 4:2:2 or 4:4:4 color is only supported when 'HDMI ULTRA HD Deep Color' is enabled in the 'Picture/Additional Settings/' menu for the chosen input.

The new α9 processor also supports 120 fps files in 1080p when played from a USB drive.

The LG C8 has an above-average sound quality. This TV gets pretty loud and has a bass with a good amount of punch and body. It also has a pretty well-balanced mid and treble ranges, which is important for producing clear dialogs. However, its bass is not extended enough to produce the thump and rumble common to film scores and sound effects, it doesn't have a self-calibrating system for room correction, and produces a bit of pumping and compression artifacts under maximum load. For a better sound, dedicated sound bars are recommended.

The LG C8 has an above-average frequency response. The LFE (low-frequency extension) is at 64Hz, which is also above-average and much improved over last year's model, the C7. This means that the bass won't be able to produce any thump or rumble, but it'll have a decent amount of punch and body to it. The frequency response above the TV's LFE is well-balanced, but since it doesn't have a self-calibrating system, it wasn't able to correct the modes of our test room (the bumps between 200Hz and 300Hz). Additionally, this TV does pretty loud, and doesn't produce too much pumping and compression artifacts under maximum load.

The remote itself is nearly identical physically to last year's C7. It has a limited selection of controls, allowing control of basic functions and quick access to the settings and search menus. When pointed at the TV the remote acts as a pointer, which when combined with the scroll wheel found in the center of the directional pad allows quick access to all options.

Voice control is now much better, on par with Samsung's service, and allows you to control other LG devices powered by ThinQ, including lights, air conditioners, etc... The TV will also be compatible with Amazon Alexa and Google Home later in the year. The basic commands we tried worked very well, and allowed us to search YouTube, switch inputs, change some settings, and even ask about the weather. In order to use voice control features (known as ThinQ AI) you must consent to sharing your viewing information and voice information, since the TV offloads certain requests to an external service. We don't know what exactly is shared with LG so if you are concerned about privacy, this should be left disabled.

    LG C8 Group Shot Picture

    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.

    LG C7
    55" 65"

    The LG C7 is 2017's entry-level OLED TV. The C7 and C8 perform very similarly. Both have excellent picture quality however the C8 handles gradients better than the C7 and has added black frame insertion, so it is a bit better for gaming. Until the C8 comes down in price, the C7 is the better buy.

    Sony A1E
    55" 65" 77"

    The Sony A1E is Sony's premium OLED TV from 2017. They both have very similar features, and both offer excellent picture quality. The C8 is noticeably brighter, but the C8 and A1E offer very similar performance. The C8 has much better input lag and better smart features. For the same price, the C8 is the better buy.

    Samsung Q8C
    55" 65" 75"

    The Samsung Q8C is the premium curved QLED from 2017. It has a good contrast ratio, although not as good as the true blacks on the OLED C8. It is not as bright and has slightly worse input lag. While the C8PUA is more expensive than the Q8C, it is a much better TV.

    Sony X900F
    49" 55" 65" 75" 85"

    The Sony X900F is the latest Sony LED TV from 2018. HDR real scene brightness on the X900F is almost 200 nits brighter than the C8, producing brighter highlights for HDR. The C8 is better suited to a bright room with wide seating due to the wider viewing angle and better reflection handling, but it is not worth the significant difference in price.

    Great Review! Question about mounting, because of how thin the TV is, have you heard of any issues using a full motion TV mount on the C8/7? (bending/damage) I would like to mount it but the placing of the VESA holes and how thin the top is worries me if I need to pull or tilt the TV. Thanks!
    There shouldn't be any issues mounting this to a full motion mount. When moving the TV it is important to always grab it by the thicker bottom third where the electronics are, as it could damage it by pushing or pulling on the screen.

    Thanks for the excellent review, as usual. Does BFI add any input lag to game mode?
    No, black frame insertion does not add any input lag to game mode.

    Primary for HDR gaming, would you recommend the C8 over the C7 Not including price? I have read the C8 is a bit brighter and offers Dynamic Tone Mapping for HDR Game mode as well as BFI (black frame insertion) similar to Active HDR on the 2017 models. Is there that much of a difference to upgrade if one already owns an LG C7? Thank you.
    The C8 has added a black frame insertion feature, which can help achieve the clearest motion possible, especially when gaming. The difference in brightness is negligible, and we do not recommend using the 'Dynamic Tone Mapping' feature as it changed the PQ curves too much. Overall, there is not enough of a difference to buy the C8 over the C7, especially if you already have the C7.
