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.

Black Friday Deals – the LG OLED B7 55" and 65" prices have dropped on Amazon by $100 and $300 respectively. See our other recommended Black Friday deals.

B&H Photo Video also have them at the same price here, with no tax outside NY and NJ.

The TV is also sold by a third party via Newegg at $1399.00 for the 55" model and at $2149.00 for the 65" model - Ended

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

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

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

Thickness

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.

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.

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.

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 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).

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.

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.

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. Unfortunately, the TV doesn't have the option to add flicker using black frame insertion, which would reduce persistence blur when gaming or using motion interpolation, like the Sony A1E does.

LG B7A Motion Interpolation (60 fps) Picture

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.

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.

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.

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.

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.

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.

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.

LG C7
55" 65"

The LG C7 is a slight step up in LG's OLED product line and is almost identical to the LG B7. The only difference between the two is the fancier stand and trim design on the C7 and the lack of Dolby Atmos support through the slightly less powerful speakers on the B7. The B7 can still passthrough Atmos though, so most people are better off with the cheaper TV.

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.

Sony X930E
55" 65"

The Sony X930E 4k LED TV is a very bright HDR TV with great picture quality. It can't match the OLED B7 in a dark room and it doesn't have the same wide viewing angle, but it can get significantly brighter. If you want the brightest TV in this price range or if you have issues with the temporary image retention of the B7, it is the best alternative for most usages. Otherwise, most people should buy the B7.

Questions & Answers

26 ANSWERED QUESTIONS
16
If supposedly all of the LG OLEDs are using the same panels, why would the B7A have worse image retention than the C7? What would cause that? Do you think it was just your unit or are the panels or processing actually different between models?
We expect the difference to be mostly caused by unit variance instead of an intentional decision by LG. The retention performance is similar to models from last year (B6, E6), which should not have a very different OLED panel than what is found on the 2017 models.
12
Did you use the latest firmware update? I and other testers have noticed picture quality improvements that should change some of the scores.
Our B7A received a firmware update shortly before we started testing (firmware 4.70.07), so we tested on the latest firmware. It had the new technicolor picture modes, for instance, and the EOTF followed the PQ curve better than most LG TVs tested previously (meaning HDR game mode wasn't too dark).

I don't know your term '24p Playback', but I can see a lot of judder in Blu-ray movies (24p) even with 'Real Cinema' and 'Trumotion De-Judder 0 De-Blur0' turned on. I did get a smooth picture with 'Trumotion' on and set to 'De-Judder 8' and 'De-Blur' above 5, but I hate the soap opera effect! Can't LG solve this?
What you're seeing is likely stutter, which just means that the framerate is low because it's 24p. OLEDs have very low motion blur, which is great for watching high framerate content, but it unfortunately makes the low frame rate stutter of 24p more visible. The TV isn't adding the stutter, just making it more obvious, while other TVs with more motion blur make the stutter less obvious. There's unfortunately no way to avoid this without adding the soap opera effect (motion interpolation).

Note that we consider stutter different from judder: judder is when some frames stay on the screen for longer than others, while stutter is when the framerate is low. The B7A has no judder from almost all 24p sources, but makes stutter more noticeable.

8
I am between this one (OLEDB7) and Samsung QLED Q7F to play Xbox One X, which one should I buy?
B7, hands down. The motion is far better due to the near-instant pixel transition time and lack of flicker, and the picture quality is much better due to the infinite contrast and perfect black uniformity. The B7 does have two big downsides for gaming though: it will have temporary image retention of the game HUD after you've been playing for a while, but this will fade within minutes. The larger concern is that it's susceptible to permanent burn in, as shown in our ongoing burn in test, however this is unlikely to be much of an issue over the TV's lifetime during normal usage. Our test is more of a torture test, though we'll use its results to make more real world conclusions when the test has run for a few more months.

Please help me understand why there's so many differences in the ratings between the OLED C7 and the OLED B7? If the only difference is the TV stand for a fancier look and Dolby Atmos for sound, why are the ratings for TV Shows, Sports, Video Games, HDR Gaming and PC Monitor higher on the C7 and lower on the B7?
Mostly because of the image retention score, which is 4 points lower (5.4 vs 1.2), however we think this is mostly due to unit to unit variance. If we tested a second C7 and B7 their positions might be reversed. We still recommend getting whichever is cheaper (usually B7).

Rtings.com, as I have a mount already installed on my wall, I was wondering if you could provide some detailed dimensions for the back of the TV. Since the mounting section of this, and all other LG OLED's are at the bottom of the TV, what is the distance from the top of the TV to the top screws for the mount?

I ask because I have an older LCD TV mounted in my living room and the mounting brackets are much higher up on the back of the set, but not centered on the back either. This way I can determine if I need to make any adjustments to the wall bracket if I decide to purchase an OLED. Have to make sure that the TV will fit above the mantle.

I just measured some dimensions of the TV, shown in a diagram here. The first VESA holes are ~16.5" from the top; the exact distance is hard to measure because of the offset between the two halves of the back.

The 55" model is currently on sale at Best Buy for $1,599.99 which is a fantastic buy. 65" model is on sale for $2,599.99.
Thank you for the heads up. The B7A will soon be added to our deals page since it is quite competitively priced for an OLED TV.

How import is the color calibration being done professionally? Can this be done via apps or something? Looking at LG B7A versus Samsung X900E for Black Friday deals and leaning B7A but the huge pre and post color calibration change worries me. The same with your burn-in test.
Generally, higher-end TVs have decent accuracy out of the box and only changing a few settings is necessary to get most of the way there. We don't tend to recommend calibration except if you feel like your TV is particularly off, even after following our recommended settings.

I have the LG B6. Is it worth replacing it with the B7?
Unless you really want a 1080p @ 120 Hz input for PC gaming, it is not worth replacing an LG B6 with the newer B7.

Hey guys, love this site! The B7P seems to have Dolby Atmos. That might make a difference for some when purchasing. That being said, does that make a difference when run through an AVR with Atmos?
True, we'll add a note about Dolby Atmos support to the Variants section. The B7A can still passthrough Dolby Atmos to a receiver, but it can't play Atmos through its own speakers because it only has a 2.0 speaker setup. The B7P has a 2.2 speaker setup, so it can play Dolby Atmos.

Have you noticed colors are completely off in PC mode HDR on the 2017 LG OLEDs? On both the PS4 Pro and Xbox One X - colors are washed out. Even when set to YUV420 instead of 422. YUV420 fixes the color banding issues.
Confirmed on all counts. In PC mode HDR colors are always undersaturated, confirmed from our Blu-ray player, Xbox One S, and Alienware 13 laptop. All players also had bad banding in PC HDR, except the laptop when playing 4:2:0. On the laptop the banding in RGB (both limited and full) was a little less bad than 4:2:2 or 4:4:4, but still not nearly as good as 4:2:0, which had banding as good as non-PC mode. We do not recommend using PC mode for HDR unless people find the chroma subsampling bothersome when reading text.

With price now being almost equal, would you buy a 55XBR930E or a 55LGB7A ?
Easily B7A; the X930E is only better if the TV will be often used in a very bright room (because the X930E is very bright).

I've read reports of even the 2017 OLEDs showing noticeable color banding even in 4K and HDR sources, as well as a fair amount of noise as part of its processing and upscaling. I'm just as sensitive if not more so with color banding than I am with light halo effects from backlight/blooming. I see it from time to time on my KS8000 and it drives me crazy! Would you say that the Sony X930E would be the best pick over the OLED in this area as well (and not just for overall brightness like in your comparison in the review)? Sony seems to consistently score highest in the gradient section and has the "smoothing" feature on top of that too. I love the look, features and improving affordability of the OLED, so I'm a little torn.
If you noticed bothersome banding and noise on the KS8000 then it's likely due to the source itself, rather than a problem with the TV, as the KS8000 was very good with gradients. Sony's 'Smooth Graduation' setting and other processing may remove this banding and noise, which will be beneficial for you. The B7A didn't have much banding or noise with any of our test materials, but we have seen cases where the infinite contrast ratio of an OLED will make noise in dark areas much more visible than on LCD TVs, because an OLED shows dark detail so much better. Even the Sony A1E revealed this noise. However unless you find banding and noise to be really bothersome, the picture quality improvements of an OLED are likely more beneficial than the banding and noise reduction of the X930E. The Sony A1E OLED would be the best of both worlds, but it is quite expensive.

I bought the OLED B7P and calibrated it according to your settings (white balance and cmd) 2 point and 20 point, but I feel it degraded the blacks a little, why? I'm a fan of your calibration (especially white balance) but I had to reset the settings because the blacks were grayish and bluish.

Also HDTVTest.co.uk said this in their review: "after 200 hours of use, a green tint slowly creeped into the dark-to-midbright portion of image, whilst the brighter area became blue-deficient". Is this correct? If yes then what's the solution?

LG says Edge Enhancer in the expert picture mode setting does not increase sharpness and they actually recommended it! Is this correct?

And last question! Should I turn on Trumotion for a 30 fps PS4 game (dejudder and deblur), because in game mode it's very stuttery!

Our 2 point and 20 point calibration settings are specific to our unit, and may cause problems with other units. We actually had a raised black level the first time we calibrated it, like yours; then we calibrated it a second time and didn't have raised blacks. If you want to calibrate your TV, use all our settings except the 2 point, 20 point and color management system settings (the little pictures at the bottom of the page), then follow our calibration guide here.

We've heard that 'Edge Enhancer On' in HDR actually bypasses the setting, but in SDR 'Edge Enhancer' works normally; so we recommend setting it to 'Off' in SDR and 'On' in HDR.

We haven't noticed any green tint on any OLED we've reviewed, but if it happens then the TV may need to be recalibrated.

Activating TruMotion when gaming will make the motion smoother but will drastically raise the input lag. This means that games will be more difficult because you'll have less time to react to what's happening before you get hit by a bullet, for example. You can try gaming in one of the other picture modes with TruMotion enabled and see how it plays.

Not knowing the particulars that you consider when choosing "for pc use numbers" I would ask that somehow ask if image retention is a consideration when gaming. Maybe a poll. This review - the LGB7 oled - has great numbers, 8.5 and 8.6 considering gaming. I disagree with the seeming lack of importance when considering image retention. While not a top consideration for every person, I feel that it will be for more than a 8.5 score will make it seem like. An 8.5 considering image retention drops it to a 6.5 for me, if after 10 minutes of testing a slight halo of image can still be seen. Nobody games for only 10 minutes. Some for a couple of hours, some half a saturday. Considering that most games have a task bar or other static image throughout a game, this becomes a factor. Maybe a disclaimer when scoring gaming that image retention can be a factor for some folks but the image and lag are superior. Judge for yourself. thanx.
Our temporary image retention test is indeed part of our Video Games and PC Monitor usage ratings, and it accounts for 6.3% and 6% of the result currently. We do try to inform our readers about the presence of image retention as well as the risk of permanent retention, but our test for the latter is not conclusive enough for us to determine a robust way to implement this in our scoring directly. The permanent retention that did appear on our unit took weeks to appear on our accelerated test and it was not visible on actual content, only on fully saturated colors. Since the interface from games rarely uses fully saturated colors that degrade the OLEDs faster, we can expect a realistic use to more in line with results of the logos shown at the right size which have a reduced intensity.

I have an LG OLED55B7T which is not on your list so I'm confused as it's 4k HDR 10bit for games and movies. It also supports Dolby vision and Atmos with 2.2 via TV speakers or pass-through. Firmware 04.70.06. I have no idea which region it is but any info you could give and add to your LG B7 review would be great. Cheers.
It appears that the B7T is an india exclusive variant of the B7. It should be similar to the B7P variant available at some retailers in North America, and it features a slightly different speaker setup which supports Dolby Atmos.

On the B7 what cable provider do you use? What kind of cable box is it? Because on my Hopper 3 from dish the image for sports and TV shows looks soft and dull. And no amount of adjustments changes that. Thanks
We use a synthetic feed for our upscaling test to reduce the risk of involving unrelated elements to the score. If it does look soft, the B7 does feature H Sharpness and V Sharpness settings which add sharpening and can enhance the clarity of some feeds. If you feel like the colors are a bit dull, you can also use the Color setting to augment the saturation of every color.

I understand that the B7A can pass through Dolby Atmos content, but can you do that with the onboard apps like VUDU and Netflix?
Yes, Atmos is supported by the TV's internal applications.

Is there a difference between the B7 and B7A? Also I am pairing with a UP970 hopefully, does this have Dolby Vision or not?
Yes, all LG OLEDs and 'S' series TVs support Dolby Vision (and some 'U' series TVs like the UJ7700). There are a few B7 models such as the B7A, B7P and B7V in Europe; the differences between them are explained in the Variants section.

Looking at the LG B7A vs Sony X930E. The LG seems to be the overall better TV from your review. However, I will be primarily watching cable TV broadcasts (720p/1080i). I’ve read mixed things online about the quality of upconversion on an LG, especially compared to Sony, on bigger screens (where flaws can be amplified). In your review, they both get a score of “8” (but almost all TVs seem to get 8’s for that). Any reason one should go with the Sony over the LG for primarily cable TV watching? Thanks for all you do! Your site is awesome!
Thanks! The X930E's upscaling is a little better than the B7A's (due to the amount of customization possible with Sony's processing), but it isn't a very significant difference. The other benefits of OLED are much more important than the difference in upscaling.

I ran your test video for 24p using a true 24p source (an Oppo BDP-83), and I don't find that TruMotion needs to be set at User:0,0, only RealCinema needs to be turned on. I verified 24p source through my receiver, and I photographed your video with a 1s exposure and found all the blocks to be evenly lit. I'm wondering if you can explain why you think this setting is necessary.
While disabling the TruMotion setting entirely will sometimes produce judder-free motion and pass our test, we've found it to be somewhat inconsistent across a few measurements. Setting the TruMotion setting to 0 on both slider has been the best way we've found to produce a consistently judder free picture.

Thank you for your review of this TV. I'm finally getting around to replacing a Samsung LN52B750, which has been great except for reflections and blacks (especially dark scenes in Sci-Fi movies). Based on your reviews and our intended use I have been going back and forth between the Sony XBR55X900E and X930E with the 930 currently in the lead. We watch 60% movies, 30% TV, and 10% sports with all sources being streaming. Looking forward to upgrading to Netflix and Amazon HDR service. Is this model a better choice over the 930 if you have a bright room during the day but watch a lot of dark scene movies and TV shows at night?
The B7 still does quite well in a bright room even if it isn't as bright as the Sony thanks to its more advanced screen finish. It will look quite a bit better in a dark room, however, but the difference might be marginal if you tend to use ambient lighting while watching TV. If most of your viewing is during the night, with little to no ambient light, then the B7 will provide a significantly better picture quality than the X930E.

On LG's website, LG said the B7A has a 4.0ch sound system while the B7P has 2.2ch sound system, what does it mean? 4.0ch is better than 2.0ch? And what's the difference between 4.0ch or 2.0 speaker?
That must be a typo: on this page (http://www.lg.com/us/tvs/lg-OLED55B7A-oled-4k-tv) it says 4.0 channel in the Audio section of the specs, but 2.0 channel in the Summary section. The 2.0 channel is correct, which means it has two normal speakers. The B7P has 2.2 channel because it has two speakers and two subwoofers, same with the C7; while the E7 has 4.2 channel because it has a four speaker sound bar with two subwoofers. More channels is generally better, and our C7 did have a bit better sound than our B7A, but sound isn't usually a big factor when comparing TVs.

Thank you for the review on this TV! I own one, I understand the TV can pass Dolby Atmos through its internal applications. Does that mean I don’t need a receiver to play Dolby Atmos? I have 2 Bose speakers with a subwoofer for my sound, currently through optical cable. How can I get the full Dolby Atmos effect using my Bose? Can I add on to the Bose system?
Dolby Atmos playback will be entirely dependent on if your Bose system supports Atmos, as the TV will just passthrough Atmos transparently. Also Dolby Atmos is likely not possible over an optical connection, so you may need an HDMI ARC connection.

How big is the color/HDR difference from the B6 to the B7 and is it worth upgrading?
The difference in color or brightness between the two generations is essentially nonexistent. Unless you want the 120 Hz input for PC gaming which is available on the newer model, the B6 will offer almost identical performance.

Are you sure that active HDR isn’t supported in game mode? I asked LG directly and they said that it does support it in game mode.
Active HDR isn't supported in game or PC mode, or at least not the same Active HDR as everywhere else. This is likely done to keep input lag low. The lack of Active HDR was most visible on the SJ9500 when running an EOTF test with constant APL (ie. as the center square gets brighter, the background gets dimmer). With 'Dynamic Contrast: Off', 'HDR Cinema' and 'HDR Game' had nearly identical EOTFs; but with 'Dynamic Contrast: Low', the EOTF of 'HDR Cinema' was much better than that of 'HDR Game', because of 'HDR Cinema's Active HDR. Setting 'Dynamic Contrast' to 'Low' in 'HDR Game' only warped the EOTF the way 'Dynamic Contrast' usually does.

Note that the dip in the 'HDR Cinema' EOTF with Active HDR occurs at stimulus 50 when the whole screen is almost one uniform shade, so the dip is likely the TV dimming the screen because it thinks it's just a blank slide with a black box.
