55-inch B7a Oled 4k Hdr Smart Tv Review

Test Results

Pattern

Curved No

The design of the C7P is not bad, and stands out in whatever room. It has a similar manner to the LG OLEDs of 2016, but with a different stand and some minor aesthetic improvements. Dissimilar the 2016 models, there are no curved options bachelor in 2017. The top tertiary of the screen is extremely thin, fifty-fifty compared to the relatively thin  LG B6.

The stand is quite different from the 2016 OLED models, with a brushed metallic finish. It supports the TV well and feels sturdy, but is also small plenty to fit on most tables.

Footprint of the 55" Idiot box stand: 8.vii" 10 22.vii"

Wall Mount VESA 300x200

The rear of the TV is similar to the B6. In that location is a removable cable management claw for guiding cables, simply it isn't as skillful as the cable direction on some other TVs such as the X930E. The controls are located on the rear of the Telly similar to the E6. If wall-mounted, some of the inputs may be difficult to access.

Borders 0.43" (i.one cm)

The borders of the Telly are very thin, and await great.

Max Thickness 1.97" (5.0 cm)

The tiptop of the TV is exceptionally sparse when viewed at an angle, even compared to the 2016 OLEDs such every bit the B6. The max thickness measurement is taken at the thicker trunk of the Television set, just information technology is still very thin. The cable management hook can exist removed to sit down flush against a wall.

Maximum Temperature 95 °F (35 °C)

Average Temperature 91 °F (33 °C)

The C7 only gets a little warm, and the heat is fairly even across the display because each pixel in an OLED produces its ain light.

The build quality is great. The Tv feels solid, although the top of the screen does feel a bit thin which can make information technology a bit more difficult to move.

Picture Quality

Native Contrast Inf : 1

Dissimilarity with local dimming N/A

The LG C7 has a perfect dissimilarity ratio, and like other LG OLED TVs, is a great performer when set in a dark room.

Local Dimming No

Backlight N/A

Since at that place is no need for local dimming on OLED TVs, this video is for reference but.

SDR Sustained 100% Window 135 cd/m²

SDR ABL 0.070

Expert SDR peak brightness, a little brighter than the LG B6 and C6. The TV remains at a consistent ~380 cd/1000² for all content except extremely big and bright images like our 100% white window, which unfortunately dims quite significantly due to the Television receiver'due south Automatic Brightness Limiter (ABL). This means that almost all scenes in SDR content will have a good brightness, but extremely bright scenes may dim.

The Telly dims over time when showing a static epitome, but this won't happen during video. A plot of SDR peak brightness over time can be institute hither.

Update 04/24/2017: ABL is less of an issue if the OLED light setting is set to 35 or less, where the fluctuations betwixt scenes will only driblet by 20 cd/m2 or less.

HDR ABL 0.100

Good HDR peak brightness, a piddling brighter than the LG B6 and C6. Although the Goggle box gets very dim when showing a pure white window due to its Automatic Brightness Limiter (ABL), it is very vivid when showing our real scene test, so about HDR content volition be very bright. However the TV is unable to achieve chiliad cd/mⁱⁱ on small highlights similar our 2% window, so small highlights in HDR content won't get as vivid as intended.

The TV dims over time when showing a static paradigm, but this won't happen during video. A plot of HDR tiptop brightness over time can be found here using the Cinema picture manner, and here using the Vivid pic mode. The Goggle box is brighter when in Vivid mode, but colors aren't equally accurate.

The overall gray uniformity of the C7 is good. There are some faint vertical lines visible when you lot look very closely and the right side is a flake warmer than the residual of the screen merely it does not testify when watching normal content. There is very little dirty screen outcome which is practiced, specially when watching sport.

The 5% gray uniformity is also proficient, and when looking at our examination film, nothing actually stands out. When viewed in a nighttime room, some vertical lines are visible, and information technology seems a chip worse than on the 2016 LG B6. Notation that those vertical lines are mostly visible when a compatible night paradigm is displayed and it very hard to notice with regular content like movies or TV shows.

Color Shift 32°

Brightness 75°

Black Level 75°

Swell viewing bending. The true blacks of this OLED TV ensure that blacks never appear washed out even at an extreme angle, and the Boob tube also remains very bright at all angles. Its weak point is its colors on an bending which exercise shift, however this should merely be noticeable for people sitting at a significant angle to the TV.

Native Std. Dev. 0.332%

Std. Dev. w/ 50.D. N/A

The C7 has flawless black uniformity when displaying a black prototype. This is due to the fact that the pixels are totally turned off and emit no light when displaying a true black. No clouding whatsoever occurs and this provides ane of the best experiences that a TV can provide, specially when watching movies in a dark room.

Screen Finish Glossy

Total Reflections ane.5%

Indirect Reflections 0.2%

The C7 is excellent at handling reflections. The purple tint present on about high-end TVs is however visible, only much less so than the 2016 OLEDs. The reflections are fine even for a bright room.

Moving-picture show Style Expert (Night Room)

White Balance dE iv.47

Colour dE 3.04

Gamma two.04

Color Temperature 6,101 1000

Out of the box the color accurateness of C7 is a fleck off and this may be noticeable to enthusiasts. The white residue dE is over 4, which is pretty high and the epitome is warmer than our target of 6500K. The color dE is as well high and only the xanthous and green track the target closely. The gamma as well doesn't track our 2.2 target.

Picture Way Expert (Nighttime Room)

White Balance dE 0.15

Color dE 1.22

Gamma 2.20

Color Temperature 6,491 K

Calibration on the LG C7 is washed pretty easily and the white balance is particularly responsive and precise. The color space management is a chip less responsive than the white balance, only that is about always the case for LG TVs. Fifty-fifty if it is a bit less responsive, the total colour dE was brought downwardly significantly to a reasonable one.22. In the end, the gamma was spot on our desired value of two.2.

You can encounter our recommended settings hither.

Upscaling of low quality content is good. Some halo artifacts tin be seen along lines merely details are preserved.

720p content such as cable is upscaled well. Some moire can be seen in the prototype from the camera focus.

1080p content such as Blu-rays are upscaled well. Details look good and the image is sharp.

Native 4k content looks expert on the C7. No issues can be seen.

Wide Colour Gamut Yes

DCI P3 xy 96.xv%

DCI P3 uv 97.xl%

Rec 2020 xy seventy.49%

Rec 2020 uv 74.07%

Outstanding colour gamut, similar to the B6 and C6 from last year. The Goggle box can accurately show nearly any colour in the P3 color space, even deep greens that many other TVs struggle with. The Rec 2020 color space is too well covered. Colors in HDR content will be well reproduced.

Normalized DCI P3 Coverage ITP 81.i%

10,000 cd/chiliad² DCI P3 Coverage ITP 44.4%

Normalized Rec 2020 Coverage ITP 61.6%

x,000 cd/m² Rec 2020 Coverage ITP 33.ane%

Decent color volume. This OLED TV is able to bear witness its wide color gamut for night and moderately vivid colors, but information technology is unable to testify extremely bright colors at their proper brightness. This should only be a problem for extremely brilliant highlights in HDR content.

Color Depth 10 Bit

Carmine (Std. Dev.) 0.131

Green (Std. Dev.) 0.119

Bluish (Std. Dev.) 0.097

Gray (Std. Dev.) 0.085

The LG C7P can display our exam image smoothly without any banding typically seen on 8-flake panels. Calorie-free shades of colour are displayed without issues, notwithstanding small imperfections can be noticed in the darker shades of colour and the dark role of the greyscale. Overall though the gradient performance is good, and these pocket-size flaws should not be a problem when watching standard content.

Update 2017-11-07: Notation that when the Television is set to 'PC' fashion, via the input carte du jour, the banding is much more visible, and this for all picture modes.

IR after 0 min recovery 0.81%

IR after two min recovery 0.ten%

The C7P OLED TV is prone to image retentiveness just like previous models. Fortunately, the prototype retention is less strong than what nosotros have measured on 2016 LG OLED TVs.

If you notice out that your Television has some image retentiveness after playing video games over a long time for case, there is a function in the 'Picture settings' page, under 'OLED Panel Settings' named 'Pixel Refresher' that will 'recalibrate' the screen to get rid of whatsoever imprinted images that may however be visible. This procedure lasts effectually 1 hour and the TV needs to be shut off for it to piece of work. This can normally take care of any image memory.

Another characteristic is likewise available on the same settings page named 'Screen Shift' that will 'move' the screen slightly (yous can't really notice information technology) to make the image retention less problematic. For our test, this feature was turned on but there is still some image retention.

Notation that at that place is a variation in temporary epitome retention between units.

Permanent Fire-In Hazard Yes

OLED panels such as the C7 practice have the possibility of experiencing burn in. You lot tin run into our investigation into this here.

Due to the RGBW pixel structure, non all of the sub-pixels on at the same time. When displaying a purple epitome more of the sub-pixels tin can be seen.

Motion

80% Response Time 0.1 ms

100% Response Time 0.2 ms

Like other OLED TVs, the C7 has an almost perfect response fourth dimension. This results in about no visible blur post-obit moving objects. Unfortunately this means that low frame rate content may announced to stutter as there is no motion mistiness to shine between the frames.

Flicker-Gratuitous No

PWM Dimming Frequency 0 Hz

The C7 doesn't flicker to dim and instead shows each image for each frame. This makes motion announced slightly more polish, but does result in some persistence blur (visible in the motility mistiness image).

Optional BFI No

Min Flicker for 60 fps 0 Hz

60 Hz for 60 fps No

120 Hz for 120 fps No

Min Flicker for 60 fps in Game Manner 0 Hz

The C7's OLED console doesn't flicker, and has no optional flicker setting like the Sony A1E does; this means that flicker can't be added to brand motion look clearer.

Motility Interpolation (30 fps) Yes

Movement Interpolation (lx fps) Yes

The C7P has a 120 Hz panel and is able to interpolate lower frame rate content to 120 fps, which significantly improves motility. Unfortunately the interpolation is not as skillful equally on some other TVs: the motion stuttered at times during normal content, specially cartoons, and artifacts would appear in rare cases.

To enable motion interpolation (also called the lather opera event) set up 'TruMotion' to 'User'. For a 30fps source increase 'De-Judder' and for a 60fps source increase 'De-Blur'.

Update 11/xiii/2017: The movement interpolation performance has been clarified in the text.

Frame Concur Time @ 24 fps 41.5 ms

Frame Hold Fourth dimension @ lx fps 16.v ms

The C7 experiences stutter, which is peculiarly noticeable with low frame rate content. This is a result of the almost instant response time, and so there is very little mistiness to smooth movement betwixt frames.

Judder-Free 24p Yep

Judder-Free 24p via 60p Yes

Judder-Free 24p via 60i Yes

Judder-Costless 24p via Native Apps Yes

The LG C7P is judder free when movies are played via 24p sources similar DVDs, Blu-ray players, and native streaming apps. To be able to display 24p content without judder, the 'TruMotion' pick must be prepare to 'User' and both the 'De-Judder' and 'De-Blur' sliders set to zero (when set up to 0, no soap opera effect will exist added).

When it come to movies playing via a 60p/60i source like cable boxes, the C7 was able to remove judder completely just by turning on the 'Existent movie theater' choice.

Native Refresh Rate 120 Hz

Variable Refresh Rate No

4k VRR Maximum N/A

4k VRR Minimum Due north/A

1080p VRR Maximum North/A

1080p VRR Minimum N/A

VRR Supported Connectors N/A

The LG C7 OLED has a native 120Hz panel like other 2017 OLED TVs, but doesn't support any variable refresh rate features.

Inputs

1080p @ 60Hz 21.iii ms

1080p @ 60Hz + HDR 21.2 ms

1080p @ 60Hz Outside Game Mode 46.iv ms

4k @ 60Hz @ four:four:4 + 8 fleck HDR 21.3 ms

4k @ 60Hz Outside Game Mode 63.0 ms

4k With Interpolation 104.vii ms

4k @ 120 Hz N/A

4k with Variable Refresh Rate N/A

1080p with Variable Refresh Charge per unit N/A

Very low input lag. When in game mode the input lag is a solid 21 ms regardless of input resolution. This should be good enough for all simply the near competitive gamers. This input lag is lower than any of LG'due south 2016 OLEDs similar the B6, and is competitive with some of the all-time TVs from last yr similar the KS8000.

Update 04/24/2017: Turning on PC mode on whatsoever of the moving-picture show modes will result in input lag of nearly 21ms. 1080p outside game fashion has been corrected after beingness re-tested.

Update 08/fourteen/2017: webOS update 3.vi fixed the PC manner HDR issue, then 4:4:4 color tin can at present exist properly displayed in HDR content. The 4:4:4 + HDR input lag has been measured equally ~21 for both 4k and 1080p, which is no dissimilar from the other low input lag measurements.

Update 09/20/2017: Tested 1080p @ 120 Hz input lag using our new input lag tool. It's nearly identical to the 1080p @ 60 Hz input lag, which is very unusual. The first on screen reaction input lag of 1080p @ 120 Hz on this TV is iv ms higher than for 1080p @ 60 Hz, which counteracts the benefits of the eight ms faster scannout of 120 Hz, producing an average input lag that is equal to the 60 Hz input lag. This may be by design, to go on the audio sync consistent between both refresh rates. Either way, ~20 ms input lag is very good for a Tv, and should delight well-nigh gamers.

1080p @ 60Hz @ four:4:four Yeah

1080p @ 120Hz Yes (native support)

1440p @ 60Hz No

4k @ 30Hz @ iv:4:4 Yeah

4k @ 60Hz Yes

4k @ 60Hz @ 4:4:4 Yes

4k @ 120Hz No

All the mutual input resolutions are supported. For the Idiot box to properly display four:iv:4 color, the HDMI input in use must take its icon changed to 'PC'. To play 4k @ 60 Hz @ iv:ii:2 or 4:4:4 color, 'HDMI ULTRA HD Deep Color' in the general settings must be enabled for the input existence used.

Update 05/31/2017: 1080p @ 120 Hz + HDR does non piece of work properly. Its brightness appears to exist following the SDR gamma curve rather than the HDR PQ bend, making everything look off and too bright.

Update 08/fourteen/2017: webOS update three.6 stock-still the PC mode HDR issue, and then 4:4:four colour can now be properly displayed in HDR content.

Dissimilar the 2016 OLEDs, the C7P doesn't have a component input.

The webOS interface is separate into three sections: settings, inputs and apps. Each has its own button on the remote, a quick menu containing common items, and a full bill of fare with advanced options. This makes the interface easy to apply and fast to navigate, only the split nature may confuse some beginning fourth dimension users.

Ads Yes

Opt-out No

Suggested Content in Home Yes

Opt-out of Suggested Content No

The TV did not display ads during our testing, but there was a personalized advertising section of the user agreement so the TV may have ads in some regions.

Update 05/25/2017: Ads were establish in voice search results, similar the UJ7700'due south search ads shown here. Information technology can be assumed that there are also ads in the LG Content Shop like on other 2017 webOS TVs.

Other Smart Features Yep

The C7's remote is bully, and it'south by and large unchanged from terminal twelvemonth's smart remote. It has a lot of advanced features that make the Tv easier to utilise. When the remote is pointed at the TV a cursor follows its movement, which allows the user to point at and select menu options directly. The cursor is very sensitive to motility and takes some getting used to, but information technology actually helps when navigating the TV. The remote also has a microphone for vocalism commands, which works well.

Differences Between Sizes And Variants

We tested the 55" (OLED55C7P). For the most office, we look our review to be valid for the 65" (OLED65C7P).

The B7 (OLED55B7P, OLED65B7P) is a warehouse exclusive model in the The states and is also available in Canada but we expect it to have the aforementioned performance, with a slightly different design.

If someone comes across a different type of panel or if their LG OLED 55C7P doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Size	US Model	European union Model
55"	OLED55C7P	OLED55C7V
65"	OLED65C7P	OLED65C7V

Compared To Other TVs

Top left: LG B6 (OLED55B6P). Bottom left: Sony X930E (XBR55X930E). Middle: LG C7 (OLED55C7P). Top correct: Samsung Q7F (QN55Q7F). Bottom correct: Vizio P Series 2016 (P65-C1).  Unlike our other photographs, this motion picture wasn't taken under a controlled environment, and then practice non draw conclusions from it.

The LG OLED C7 is one of the best TVs available today and its moving-picture show quality cannot be matched, but it's a very small-scale comeback over last year's models. Encounter our recommendations for the best flatscreen TVs.

55" 65" 77"

The LG C8 is a fleck better than the LG C7. While the overall performance of the two is very similar, the LG C8 has an optional Blackness Frame Insertion feature that the C7 lacks. This feature can amend the perceived clarity of motion on the C8 at the expense of some effulgence.

55" 65"

The LG B8 is somewhat better than the LG C7. The B8 has a black frame insertion (BFI) characteristic that tin can innovate flicker to clear blur in fast-moving content, whereas the LG C7 has a lower input lag when y'all play HDR games. Other differences like the B8'southward less temporary epitome retention or the C7's better gray uniformity tin can exist attributed to panel variance.

55" 65" 77"

The Sony A1E is marginally ameliorate than the LG C7. The Sony A1E has an optional Black Frame Insertion feature that tin ameliorate the clarity of motion. The LG C7 doesn't support Black Frame Insertion, merely it has much ameliorate (lower) input lag, great for gaming.

55" 65" 77"

The LG C9 OLED is a bit better than the LG C7 OLED. The two TVs were tested nether dissimilar examination benches, just some comparisons tin even so exist fabricated. The C9 has wider viewing angles and lower input lag, and is more future-proof thank you to its input ports. The C9 has 4 HDMI 2.ane inputs, which for the moment doesn't add much if anything at all. When HDMI two.1 sources get available, the C9 should back up a 4k @ 120Hz input, even at total chroma. The C9 also supports eARC and supports the HDMI 2.1 variable refresh rate technology, which is currently simply supported past the Xbox One.

49" 55" 65" 75" 85"

The LG C7 is better than the Sony X900F, unless yous consume a lot of static content and the possibility of burn down-in concerns you. The LG C7 uses an OLED console that delivers perfect dark room operation thanks to the infinite contrast and perfect black uniformity. The C7 besides has wider viewing angles, good for a wide seating expanse. Since the C7 uses an OLED panel, in that location is the possibility of permanent burn-in or temporary image retention. The X900F uses a VA panel which is not prone to burn-in.

55" 65"

The performance of the LG B7A and LG C7 is most identical. There are no major differences other than the pattern. The LG C7 and the B7P variant accept a two.2 speaker setup, which can internally decode Dolby Atmos sound. The B7A variant simply has a 2.0 speaker setup and tin can't decode Dolby Atmos internally, although the C7 and all B7 models can output Atmos to an external receiver.

55" 65"

The LG E7P has a very similar operation to the LG C7. They have very similar scores in all our tests, and the main difference is the presence of a dedicated soundbar on the E7P. Also, the operation of our temporary image retention test was slightly better on the E7P, but this can be attributed to panel variance.

55" 65"

If you are a movie fan, then go with the LG C7, whereas if you lot use your Boob tube as a PC monitor or watch the news with static banners for prolonged periods of fourth dimension, become with the Sony X930E. The LG C7 has perfect blacks that are neat for movies and HDR content in nighttime rooms. The LG C7 also has a slightly ameliorate response fourth dimension and somewhat better input lag then that yous can enjoy playing video games. Finally, the LG C7 has better viewing angles for those sitting on the side and better gray uniformity for those sports fans. The Sony X930E is a better selection if you lot worry besides much about the permanent burn-in.
