Resolution : 4k

The LG B7 is a high-end 4k OLED smart TV with exceptional picture quality thanks to its infinite contrast ratio and wide viewing angle. It produces little motion blur, and its ability to reproduce a very wide gamut of colors and relatively high peak brightness helps it produce an impressive HDR image. It does, however, tend to retain a ghost of static images temporarily and isn't quite as bright as some LCD TVs. It offers the same performance as the B7P found at warehouse stores like Costco and Sam's club.

Design

Score components: Subjectively assigned
LG B7A Design Picture
Curved : No

The design of the LG B7 OLED is excellent. The TV looks impressive, with a very thin screen and thin borders. It doesn't have the front-facing soundbar of the E7, and instead, sits on a stand similar to the B6. Some of the rear-facing inputs may be difficult if placed close to a wall, but the two HDMI and two USB ports on the side are easily accessible.

Stand
LG B7A Stand Picture

The stand of the B7A has a relatively small footprint and looks very similar to the B6 we reviewed last year. It has a clear support, which looks good and overall feels stable.

Footprint of the 55" TV stand: 8.9" x 22.2"

Back
LG B7A Back Picture
Wall Mount : VESA 300x200

The rear of the TV is minimal but looks good. Some of the rear facing inputs may be difficult to access if placed close to a wall though.

Borders
LG B7A Borders Picture
Borders : 0.43" (1.1 cm)

The borders are thin and look great. The edges of the TV are metal and feel well-built.

Thickness
LG B7A Thickness Picture
Max Thickness : 1.97" (5.0 cm)

The TV is very thin when viewed from the side, and the top half of the TV is only as thick as the OLED screen and backing. The bottom half of the TV houses the components and is thicker, but still will stick close to a wall if mounted.

Picture Quality

The LG B7 OLED TV has a remarkable picture quality. When set in a dark room, the amazing contrast ratio and the excellent black uniformity makes for a great home cinema experience, where dark scenes are well reproduced, with deep blacks. When set in the brighter room, its very good SDR peak brightness and excellent capacity to deal with reflection mean the B7A can also be a very good option to watch TV shows and movies during the day. The B7 is a good TV for people with a large living room since it has a very good viewing angle and picture quality remain good no matter where you will be sitting. The B7A is also a good TV for the sport's amateur, as the gray uniformity is great and dirty screen effect is not really a problem. Finally, when it comes to HDR, the B7 is excellent, as the mix of perfect blacks and good HDR peak brightness produces strong specular highlights, and when you add the wide color gamut, you can really experience a great HDR experience.

No
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.

Plot over time

Good SDR peak brightness, good enough for most bright rooms. Like other OLED TVs, the B7A unfortunately has an Automatic Brightness Limiter (ABL), though in this case it only lowers the brightness for scenes with a very high average brightness like our 100% white window. This means that the ABL should be rarely noticeable while watching normal content. However, it is very noticeable during PC monitor use as white windows are common. Overall, the B7A's brightness is very similar to its siblings the OLED C7 and E7P, but behind many high end LCD TVs like the Sony X930E and Vizio P Series 2017.

Plot over time

Good HDR peak brightness. Because each OLED pixel is its own light source, in a typical HDR scene the TV can use the power savings from the dim pixels to make the bright pixels even brighter, producing a good brightness in our real scene test. This isn't as helpful in very bright scenes like our 50% white window test, where the TV's Automatic Brightness Limiter (ABL) dims the TV significantly, but luckily such bright scenes are rare in HDR content. Overall, the brightness is similar to the OLED C7 and E7P, but not as good as some high end LCD TVs like the Sony X930E and the Samsung Q9F. If users find the B7A too dim, increasing the 'Dynamic Contrast' setting will make the scene brighter but won't change the brightness of highlights.

The overall gray uniformity of the B7A is great. On the 50% gray test picture, some warmer patches are visible (on the left side of the screen), but those are mainly visible when displaying a uniform gray color and do not affect normal content. Since the screen is pretty even, no dirty screen effect is visible when watching sports like football or hockey.

On the 5% gray, some really faint vertical line are visible, but this is similar to other 2017 LG OLED TVs. Luckily, this is only visible in dark room and while looking at very dark uniform colors, which is fairly rare in TV shows or movies.

Great viewing angle, far better than most LED TVs, as expected of an OLED. Blacks remain perfectly black and the brightness decreases only slowly at an angle, though colors do degrade more quickly. Overall, this TV is an excellent choice for a room where people often sit to the side of the TV and view it at an angle.

The B7 is excellent at handling reflections. It has the same glossy finish and anti-reflective coating as the C7 and E7, which works very well to reduce the intensity of direct reflections and glare. The glossy screen doesn't distort or reduce the sharpness of the screen. As with other high-end TVs, there is a purple tint as a result of the coating which is most visible when the TV is off. Most people won't mind this, and overall, the reflection handling is fine even in a bright room.

When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.
Good value: 6500K
Noticeable difference: 400K

Out of the box, when set on 'ISF Expert (Dark Room)', the accuracy of the B7A could be better. Both the white balance dE and color dE are high enough so that most enthusiasts would notice the inaccuracies. Note that the 'technicolor Expert mode' has the same accuracy than the 'ISF Expert (Dark Room).

The gamma is a bit higher than our desired 2.2 target and if you do not intend to calibrate your TV and notice that there is black crush (loss of detail in the dark region of the screen), you could simply raise the gamma in the 'Expert controls' menu and it should fix this issue.

9.6 Post Calibration
What it is: TV's color accuracy after a full calibration with a spectrophotometer.

Color Temperature
What it is: The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.
When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.
Good value: 6500K
Noticeable difference: 400K

After calibration, all the issues were corrected and the white balance dE and color dE was brought down significantly and are now well below what most people would notice. The gamma value is right on our 2.2 target and the curve is now following our target curve very well. The calibration process went well and the 2 points and the 20 points white balance correction were easy to apply and the precision of both helped considerably. The color space management system was also precise and easy to use.

LG B7A EOTF

Great wide color gamut, one of the best of 2017, and only a little worse than the Samsung QLEDs like the Q7. Saturated colors in HDR content will be well represented. The TV's accuracy with the colors within its gamut could be better, as almost all points artificially undershoot their targets and saturated cyan turns green.

The EOTF in the technicolor picture mode (with Active HDR on) follows the target PQ curve almost perfectly until it clips at its peak brightness. The EOTFs in Game and PC modes have similarly great accuracy. Raising the 'Dynamic Contrast' setting above 'Low' will make the EOTF brighter, which may be useful when watching HDR in a bright room.

Update 11/10/2017: The Active HDR feature ('Dynamic Contrast: Low') doesn't work in Game or PC mode; 'Dynamic Contrast: Low' only applies normal dynamic contrast (brightens the EOTF a bit near the high end). Our Game and PC mode EOTF tests were done with 'Dynamic Contrast: Off'.

Decent color volume. The OLED panel is able to show its wide color gamut at incredibly low brightness, which is great. Unfortunately, it loses a lot of color volume at high brightness because it cannot make saturated colors nearly as bright as it can make pure white, because of its RGBW pixel structure.

The B7 can display our gradient test image very good and no banding normally seen on 8-bit TV can be noticed. Some imperfection can be seen in darker colors and grayscale, but this is in lines with other OLED TV like the C7 and E7P and it does not cause major banding when watching normal content.

Update 2017-11-07: Note that when the TV is set to 'PC' mode, via the input menu, the banding is much more visible, and this for all picture modes.

The LG B7 has a bad result on our image retention test, as we detected some faint ghost remnant of the Rtings logos even after 10 minutes of recovery. This is a worse result than we tested on the C7 and the E7, which were both better on this test and this result is more in line with the 2016 B6. This is likely only due to panel variance though, as all 2017 LG OLED TVs should perform very similarly as the panel used in those supposed to be the same. Playing normal video content for a couple more minutes did make any image retention that was still visible go away though.

As mention on for the C7, if you find out that your TV has some image retention after playing video games for a long time or after having watched a news channel with a static logo, 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 any imprinted images that may still visible. This procedure lasts around one hour, and the TV needs to be shut off for it to work. This can usually take care of any image retention if watching normal content (without static image) did not make it go away.

'Screen Shift' is also another feature that will 'move' slightly (couple pixels) the screen to make the image retention less problematic. For our test, this feature was turned on but there was still some image retention anyway, so this function is not perfect.

Note that this temporary retention is not the same as permanent image retention (burn-in), which requires looking at the performance of the TV over a long time (months or years).

Note that there is a variation in temporary image retention between units.

Motion

Motion looks excellent on the B7 OLED. It has near-instant pixel response time, flicker-free lighting, judder-free 24p playback from almost any source, and 120 fps motion interpolation. The only thing it's missing is black frame insertion, which would've only been useful for gaming or when using motion interpolation.

Near-perfect pixel response time, far better than any LED TV, as expected of an OLED. All the blur in the image is due to 60 fps persistence, no response time blur can be seen. The black to 20% dark grey transition does have some overshoot, but this shouldn't be too visible.

Unfortunately, this lack of motion blur is a disadvantage when watching movies when motion interpolation is not enabled, as the very low frame rate of movies is made more obvious by the lack of blur, causing them to look more stuttery than normal.

10 Flicker-Free

The OLED panel dims without using any PWM, which is great because PWM adds double image artifacts. Some small flicker is measurable, but this shouldn't be visible.

0 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.

What it is: Whether the TV can take a 60 fps input and heighten the frame rate to at least 100 fps.
When it matters: 60 fps videos. Includes some video games, some sports channels.
:
Yes

The TV can use the soap opera effect to interpolate the frame rate of nearly any content into smooth 120 Hz. This significantly reduces motion blur, but this smooth motion may appear strange to those not used to it. Unfortunately this TV's interpolation isn't as good as on some other TVs: the motion stuttered at times during normal content, especially cartoons, and artifacts would appear in rare cases.

To activate motion interpolation for lower frame rate content, set 'TruMotion' to 'User' and raise the 'De-Judder' slider. For 60 fps content, raise the 'De-Blur' slider.

Update 11/13/2017: The motion interpolation performance has been clarified in the text.

The LG B7A is bad at showing low frame rate content without stutter. The frame transition occurs almost instantaneously which can be quite jarring, as the image is static for about 40ms each frame of a movie. This is especially noticeable with wide panning shots. The only way to reduce this stutter is to increase the frame rate of the content through motion interpolation.

When it matters: When gaming with a device which supports variable refresh rates, such as the Xbox One X or a PC.
:
N/A

Excellent low input lag, good enough for all but the most competitive gamers. Normally only the 'Game' picture mode has low input lag, however when in 'PC' mode all picture modes have low input lag. 4:4:4 color is only properly displayed in PC mode, but it's usually only relevant for PC use anyways. Overall, the input lag is very similar to the LG C7 and most Samsung TVs, and better than most Sony TVs, but not quite as good as the LG SJ9500 and TCL P607.

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The LG B7 features the same "Magic Sound Tuning" room correction feature found on other high-end LG TVs, but it's less powerful set of speakers means its performance is still only average. It's not bad, but a good sound bar will provide a significant upgrade to the sound quality.

6.4 Frequency Response
What it is: How accurately the sound level of each frequency is being produced.
When it matters: For a balanced and neutral sound.
LG B7A Frequency Response
Low-Frequency Extension
What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Movies, Gaming. Shows how extended the bass is.
Good value: < 60Hz
Noticeable difference: 10Hz
:
100.79 Hz
Std. Dev. @ 70
What it is: The amount of deviation (weighted standard deviation) in frequency response measured at 70dB SPL, as compared to a target response that would sound perfectly balanced to most people.
When it matters: Shows the TV's frequency response at quiet listening levels
Good value: < 4 dB
Noticeable difference: 0.5 dB
:
3.01 dB
Std. Dev. @ 80
What it is: The amount of deviation (weighted standard deviation) in frequency response measured at 80dB SPL, as compared to a target response that would sound perfectly balanced to most people.

What it is: Maximum volume reached by the TV at their optimum viewing distance (size dependent)
When it matters: For listening to loud audio.
Good value: > 88 dB
Noticeable difference: 2 dB
:
84.7 dB SPL
Dynamic Range Compression
What it is: The amount of difference between the TVs frequency response performance at 70dB SPL and Max dB SPL. Too much compression will result in pumping in the sound.
When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
4.06 dB

Passable frequency response. The LG's room correction feature helps the TV track our target quite well, but it does have a slight overemphasis in the treble range that makes the TV sound a little bright. However, the TV uses a significant amount of dynamic range compression to reach higher volume settings, and it doesn't make it very loud.

6.2 Distortion
What it is: Deformation of an output signal compared to its input, usually clipping, harmonic distortion, or inter-modulation distortion caused by non-linear behavior of the sound system.
When it matters: When a clean, pure and transparent reproduction is desired.
Score components:
LG B7A Total Harmonic Distortion
Weighted THD @ 80
What it is: The overall amount of harmonic distortion measured at 80dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.

What it is: The average amount of inter-modulation distortion produced by the TV under maximum load. The percentage shown here is the average result of 3 separate test signals/standards: SMPTE, DIN, & CCIF
When it matters: When a clean and free of aliasing reproduction is desired
Good value: < 5%
Noticeable difference: 2
:
21.47 %

Average distortion performance. The LG B7's THD levels are relatively low at most volumes, but IMD rises significantly when the volume is increased. Since minor aliasing appears at higher levels for very little actual volume gain, it is better to keep the slider under the 50% mark.

The B7 uses LG's WebOS smart platform, which is fast to navigate, has lots of apps and has a great remote. The interface is split into three sections; apps, settings and inputs; each with its own button on the remote, quick menu and full menu. This makes the interface fast to navigate, but may be confusing for first-time users. The included LG Magic Remote is one of the best and makes a cursor on screen follow the remote's movement, much like a Nintendo Wii remote, which saves time when browsing the TV.

The B7A comes with LG's excellent Magic Remote, which has some useful smart features and clever design choices. Although the remote is large, most of its thickness and weight is at the bottom where your hand is, so it feels very ergonomic to use. The remote's standout feature is making an onscreen cursor follow the remote's movement, much like a Nintendo Wii remote. This allows you to select menu items directly, which saves time.

Differences between Sizes and Variants

We tested the 55" (OLED55B7A). For the most part, we expect our review to be valid for the 65" (OLED65B7A).

The B7P (OLED55B7P, OLED65B7P) is a warehouse exclusive model in the USA and is also available in Canada but we expect its performance to be identical. One difference is that the B7P can play Dolby Atmos using its own speakers because it has a 2.2 speaker setup, while the B7A can't play Atmos with its own speakers because it only has a 2.0 setup. The B7A can still passthrough Atmos to an external receiver though.

The B7V (OLED55B7V, OLED65B7V) is a European variant which sports a different stand, similar to what is found on the LG SJ8500. We also expect this to offer the same performance as the German B7T (OLED55B7T, OLED65B7T).

If someone comes across a different type of panel or if their LG OLED 55B7A (55OLEDB7) or 65B7A (65OLEDB7) 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.

Compared to other TVs

LG B7A Group Shot Picture
Top left: Samsung MU9000 (UN55MU9000). Bottom left: LG C7 (OLED55C7P). Middle: LG B7A (OLED55B7A). Top right: Vizio P Series 2017 (P65-E1). Bottom right: Sony X930E (XBR55X930E).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG B7 is a great TV overall and offers a lot of value for money. Since it has the best picture quality while still being reasonably priced, it's a very competitive model. See our recommendations for the best smart TVs and the best 4k TVs.

LG B8
55" 65"

The LG B8 is somewhat better than the LG B7A. The LG B8 has slightly better motion handling due to the black frame insertion (BFI) feature which is great if you play video games and also the LG B8 performs somewhat better in temporary image retention if you use it as a PC monitor, although this could be due to panel variance. On the other hand, the LG B7A has marginally better input lag in HDR gaming and marginally better viewing angles, although both TVs are very good in that respect.

LG C7
55" 65"

The performance of the LG B7A and LG C7 is nearly identical. There are no major differences other than the design. The LG C7 and the B7P variant have a 2.2 speaker setup, which can internally decode Dolby Atmos sound. The B7A variant only has a 2.0 speaker setup and cannot decode Dolby Atmos internally, although the C7 and all B7 models can output Atmos to an external receiver.

LG C8
55" 65" 77"

The LG C8 is somewhat better than the LG B7A. While the overall performance of the two is very similar, the LG C8 has an optional Black Frame Insertion feature that the B7A does not have. This feature helps to improve the perceived clarity of motion on the C8, at the expense of some brightness.

Sony X930E
55" 65"

If you watch movies or HDR content in a dark room, then the LG B7A is a better choice, whereas if you extensively use your TV as PC monitor or watch a lot of news with static banners, go with the Sony X930E. The LG B7A, as an OLED TV, has perfect blacks that you will appreciate in a dark room while watching movies. Also, the LG B7A has a somewhat better response time and a bit better input lag to please those who play video games. Watching sports with a group of friends is better on the LG B7A as it has slightly better gray uniformity and better viewing angles to accommodate those viewing from the side.

Sony X900E
49" 55" 65" 75"

The LG B7A is better than the Sony X900E, unless you watch a lot of static content and the possibility of burn-in concerns you. The LG B7A uses an OLED screen, which has the possibility of burn-in, but provides perfect dark room performance and great wide viewing angles. The B7A has lower input lag, great for gaming. The Sony X900E does not experience any temporary image retention, and appears to be immune to the effects of burn-in.

LG E7P
55" 65"

The LG E7P has a very similar performance to the LG B7A. The two TVs score almost the same in most of our tests. The main difference is the presence of a dedicated soundbar found on the E7P to improve sound performance and the temporary image retention where the E7P is doing better, but this can be attributed to panel variance.

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

The LG B7A is better than the Sony X900F, unless the possibility of burn-in concerns you. The LG B7A uses an OLED panel, which offers perfect dark room performance and wide viewing angles. The B7A is prone to temporary image retention, and there is the possibility of permanent burn-in. The Sony X900F appears to be immune to burn-in and does not experience any image retention.

LG SJ9500
65"

If you enjoy watching movies in a dark room, then the LG B7A is a better choice, but if you will be watching a lot of static content like news, then the LG SJ9500 is better. The LG B7A has perfect blacks that improve the picture quality in a dark room. Also, the LG B7A has a bit better viewing angles and somewhat better reflections which is great for wide seating arrangments and rooms with many light sources. On the other hand, the LG SJ9500 has marginally better input lag which is great for video gaming and does not have the permanent burn-in risk OLED TVs have.

Samsung MU9000
55" 65" 75"

The Samsung MU9000 is a midrange 4k LED TV which features an advanced screen finish that enables it to handle reflections much better than average. It's not as good a TV as the B7A overall, but it's a good and less expensive alternative if you watch your TV with some ambient light and don't need the additional features that the OLED offers.

Vizio P Series 2017
55" 65" 75"

The Vizio P Series 2017 is a 4k LED TV with great picture quality in a dark room thanks to its powerful local dimming feature. It doesn't quite match the B7's picture quality, and it's not quite as versatile, but its a good alternative to the LG B7A for the movie buffs that want a larger TV in this price range.
