The 4k LG C7 OLED TV offers excellent picture quality thanks to its ability to display true blacks. It's especially good for gaming thanks to its very low input lag and motion blur. It gets fairly bright, and it can display a wide range of colors, so it's also a great HDR performer. Unfortunately, it can retain static images for a few minutes, and brightness levels fluctuate depending on the content, so it isn't perfect.

Pros
  • Perfect blacks produce an infinite contrast ratio
  • Virtually no motion blur, fast moving content is very clear
  • Picture quality is retained, even at steep angles
Cons
  • Temporary retention can happen when static images stay on screen too long
  • Brightness levels vary depending on content being played (ABL)

LG C7 Design Picture
Curved : No

The design of the C7P is great, and stands out in any room. It has a similar style to the LG OLEDs of 2016, but with a different stand and some minor aesthetic improvements. Unlike the 2016 models, there are no curved options available in 2017. The top third of the screen is extremely thin, even compared to the relatively thin  LG B6

Stand
LG C7 Stand Picture

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 enough to fit on most tables.

Footprint of the 55" TV stand: 8.7" x 22.7"

Back
LG C7 Back Picture
Wall Mount : Vesa 300x200

The rear of the TV is similar to the B6. There is a removable cable management hook for guiding cables, but it isn't as good as the cable management on some other TVs such as the X930E. The controls are located on the rear of the TV similar to the E6. If wall-mounted, some of the inputs may be difficult to access.

Borders
LG C7 Borders Picture
Borders : 0.43" (1.1 cm)

The borders of the TV are very thin, and look great.

Thickness
LG C7 Thickness Picture
Max Thickness : 1.97" (5.0 cm)

The top of the TV is exceptionally thin when viewed at an angle, even compared to the 2016 OLEDs such as the B6. The max thickness measurement is taken at the thicker body of the TV, but it is still very thin. The cable management hook can be removed to sit flush against a wall.

Picture Quality

The LG C7P OLED TV has an excellent picture quality. The infinite contrast ratio and perfect blacks make for an amazing movie experience, especially when the TV is set in a dark room. When set in a bright room, the C7 also has good picture quality since it can get bright enough to fight glare and it does a remarkable job at dealing with reflections. The very wide viewing angle and the good gray uniformity make the C7 an excellent choice for watching sports with a large group of people or if you have a wide seating area. When it comes to HDR, this TV does a superb job making HDR content shine when compared to SDR content. The perfect contrast ratio, good HDR peak brightness and large color gamut coverage make HDR content really pop.

Good SDR peak brightness, a little brighter than the LG B6 and C6. The TV remains at a consistent ~380 cd/m2 for all content except extremely large and bright images like our 100% white window, which unfortunately dims quite significantly due to the TV's 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 TV dims over time when showing a static image, but this won't happen during video. A plot of SDR peak brightness over time can be found here.

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

Great HDR peak brightness, a little brighter than the LG B6 and C6. Although the TV gets very dim when showing a pure white window due to its Automatic Brightness Limiter (ABL), it is very bright when showing our real scene test, so most HDR content will be very bright. However the TV is unable to reach 1000 cd/m2 on small highlights like our 2% window, so small highlights in HDR content won't get as bright as intended.

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

The overall gray uniformity of the C7 is good. There are some faint vertical lines visible when you look very closely and the right side is a bit warmer than the rest of the screen but it does not show when watching normal content. There is very little dirty screen effect which is good, especially when watching sport.

The 5% gray uniformity is also good, and when looking at our test picture, nothing really stands out. When viewed in a dark room, some vertical lines are visible, and it seems a bit worse than on the 2016 LG B6. Note that those vertical lines are mostly visible when a uniform dark image is displayed and it very hard to notice with regular content like movies or TV shows.

Great viewing angle. The true blacks of this OLED TV ensure that blacks never appear washed out even at an extreme angle, and the TV also remains very bright at all angles.

The C7 has flawless black uniformity when displaying a black image. This is due to the fact that the pixels are totally turned off and emit no light when displaying a true black.

The LG C7P can display our test image smoothly without any banding typically seen on 8-bit panels. Light shades of color are displayed without problems, however small imperfections can be noticed in the darker shades of color and the dark part of the greyscale.

Calibration on the LG C7 is done pretty easily and the white balance is particularly responsive and precise. The color space management is a bit less responsive than the white balance, but that is almost always the case for LG TVs. Even if it is a bit less responsive, the total color dE was brought down significantly to a reasonable 1.22. In the end, the gamma was spot on our desired value of 2.2.

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

If you find out that your TV has some image retention after playing video games over a long time for example, 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.

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

The motion handling of the C7P is excellent. The response time is near perfect resulting almost no visible motion blur. The TV doesn't flicker by default, but unfortunately, it can't enable any flicker to reduce blur further.

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 but the most competitive gamers. This input lag is lower than any of LG's 2016 OLEDs like the B6, and is competitive with some of the best TVs from last year like the KS8000.

The C7 runs LG's WebOS smart platform. It is easy to use and feature filled, and makes very effective use of the TV's smart remote. The remote has a few buttons that open quick menus, like the settings and inputs buttons, so the user doesn't have to go into the main settings menu. When the remote is pointed at the screen a cursor follows its movement, so menu items can be selected directly without using the arrow keys to navigate to them. The remote has a microphone for voice commands which works well. Content can be played directly from a USB drive attached to one of the TV's three USB ports.

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

The LG OLED C7 is one of the best TVs available today and its picture quality cannot be matched, but it's a very minor improvement over last year's models.

LG B6
55" 65"

The LG B6 is 2016's entry-level OLED TV. It's been replaced by the C7, but the difference between them is very minor. The picture quality is almost identical, and the input lag is the only real advancement, although the B6 is still pretty good in that regard. Considering the big price difference, almost nobody should be buying the C7 over the B6 from last year.

Sony X930E
55" 65"

The Sony X930E is one of Sony's high-end LCD TVs in 2017. It's a great TV, but the C7 has some advantages such as the perfect blacks and wide viewing angle. The X930E does get significantly brighter, but most people will find the C7 to be a more suitable choice. It is a fair bit cheaper than the C7 though which is a big advantage.

Samsung Q7F
55" 65" 75"

The Samsung Q7F is the entry level model from their QLED line of LCD TVs. It's a bit cheaper than the LG, but it's mostly a downgrade. It can display a wider range of colors, which is great for HDR, but it isn't worth picking over the C7.

Vizio P Series 2016
50" 55" 65" 75"

The Vizio P Series 2016 is Vizio's top of the line TV. It features the best local dimming we've tested and has great picture quality in a dark room. It's far less versatile than the OLED, but since it's available for a fraction of the price, it can be a good buy for those on a tighter budget.

For non-experts, but those who still enjoy a high end experience, is the difference between this year's OLED models worth the extra spend, or is last year's models still a solid choice?
Except for the niche gaming additions, an LG B6 from last year will provide almost exactly the same performance.
15
I recently bought the B6P, would you say the 7 line is enough of an upgrade to return my B6P for say the C7P? I mainly use my B6P for movies and games (PS4 Pro).
The difference between them is very minor and we feel is not worth the price difference. If you are happy with your B6 and don't have any problem with it, save yourself some trouble and keep the B6.
13
Does the C7 really support 120hz input (at 1080p)? The 2016 models didn't, and you don't remark upon it, so I wanted to make sure it wasn't an error.
It is not an error, and we did not have to create a custom resolution in the Nvidia control panel, it was available to select from the drop down menu.
11
For which buyers, or under which specific circumstances would you recommend the C7 over the B6? I assume the same deciding factor of cost would apply for the B6 vs. B7?
The C7 and B6 perform very similarly, and we expect the B7 to be similar as well, so almost everyone should buy whichever is cheapest. Only PC gamers who want to game with proper 4:4:4 color and find 34 ms of input lag unacceptable would be better served by the C7 than the 2016 OLEDs, due to the C7's 21 ms PC mode input lag compared to the C6 and E6's 34 ms and the B6's ~65 ms.

Hi! I have the C7 and the Leo Bodnar tester and PC mode gives the same 21ms of lag even in ISF bright and dark modes, this is important to gamers that want accurate picture settings and the same low lag as game picture mode. This only works in PC mode! Also there is no ABL on this set of you keep the oled light at 35 or below. At 35 oled light it gives 150 nits. I thought you may want to inform buyers of these two things! Best regards, Luke
That is indeed correct and can be seen in our 4:4:4 input lag test. The text has been updated to better represent this. As for the ABL, we've found that there is still some dimming with the 100% slide while using a setting of 35, but only of about 20 cd/m2. This is minimal and definitely makes it less of an issue. The SDR peak brightness of the review has been updated accordingly. Thanks for the information!

Why does LG still use ABL in their TVs? They have been making OLED TVs for years now and still do not understand how to battle burn-in without resulting to ABL. ABL is the main reason why I don't own my EG9100 and settled for the Vizio P. Why does ABL continue to be a thing in newer OLED TVs?
ABL's purpose is less about burn-in, and more about power consumption. Without brightness limits, the LG C7 would consume 3x as much power or more when displaying content that is bright across the whole screen. Considering OLED TVs already top our power consumption tests, this could make it use beyond 500W of power which is fairly unreasonable.

This line is confusing me:
'The LG B6 is 2016's entry-level OLED TV. It's been replaced by the C7'
But it appears there is a B7, yes?
www.lg.com/us/tvs/lg-OLED65B7P-oled-4k-tv
The B7 is a warehouse exclusive model, so the C7 is the mass market successor to the B6.

Just noticed "Gradient" is actually worse than last year's model, so more color banding for 2017?

There is not much difference between the C7 and the B6, as they scored very close on the gradient test (only 0.5 better for the B6). On a side by side comparison with the B6, on the same scene of the same movie (The Martian at 00:46:36), both the C7 and the B6 had very similar banding. We also checked the Sony A1E and it looked better than both LGs.

Okay, so money isn't a problem, but I'd still like to save $1500 when I can. Is it worth buying over the B6 or C6?
Not really. Like we have said, the difference between them is very minor. Get the B6 and save some money.

Does the LG C7 or any Dolby Vision capable TV's support Dolby Vision over HDMI? If not how will that affect UHD Blu-rays with Dolby Vision later this year?
The C7 supports Dolby Vision over HDMI, we tested with a Chromecast Ultra.
4

According to hdtvtest there is a way around it:

Engaging Game mode resulted in a response time of 21 ms, but additional benefits could be gained by using another method: labeling an HDMI input as 'PC' would produce the same low latency, with the added bonus of full 4:4:4 chroma reproduction and accurate colours in the calibrated 'ISF Expert' presets. However, relabeling the HDMI input to 'PC' didn’t lower input lag in HDR. In order to reach a response time of 21 ms with HDR, we had to use 'HDR Game' mode where 'Colour Gamut' could be switched from 'Wide' to 'Auto' for more accurate colour reproduction.

We were able to confirm that following the steps you mentioned allow for 21 ms responsiveness and 4:4:4 chroma reproduction on the C7. We also found the same results in HDR Game mode.

Thank you for your feedback.

Last year's models placed the inputs close to the edge of the Tv and meant cables often showed from the front. Is it the same this year or are they inset more?
The position of the connectors is the same.
3
You note that the C7 can correctly display motion for 24p content that is embedded within a 60p or a 60i signal. Does the RealCinema feature now work with 60p sources? On my 2016 B6, the RealCinema menu item is grayed out on 60p or 30p sources since it was only designed to work on interlaced sources such as 60i. Did LG improve RealCinema for their 2017 models so that it works on both 60i and 60p sources, like Sony's MotionFlow?
Yes, this is a change to the way 'RealCinema' works. On the C7, the 'RealCinema' option is available when sending a 60p/60i resolution unlike on 2016 OLED TVs
3
As the B6 is being cheaper as it is a last year's model. Do you know if it can be updated to WebOS 3.5? The "new features in 2017 models really add more value in long term? I would not like to buy a B6 if relevant new features are not available. Thanks a lot
The LG B6 probably can be updated to WebOS 3.5, but there aren't features in that update that we would consider a dealbreaker to not have.

Just a general oled question. When looking into the tech, it seems that the response time of oleds are superior to the speed of lcd's. All of them. The Rtings(lol) on "the net" are posted as 0.001ms. One thousandths of a millisecond. This would mean 1 micro second (0.0000001 sec). Or is it as I believe, 1 ms(0.001sec) 1 millisecond but someone somewhere micro'd the milli and thus we see the response time posted as 0.001 msec? What is the true response time of a oled? Either way, if the response time is soo superior, when will manufacturers get on the ball and have something like a direct to screen mode that takes as much of the video processing possible out of the display equation to further improve speed.
The response time of current OLED TVs is effectively 0ms. We rate it at 0.2ms, but that is mostly because it is difficult to actually calculate the response time within that very small margin.
3
LG finally fixed their input lag issues with the tv, so would you say that OLEDs is finally worthwhile for gaming and HDR gaming?
Yes, definitely. The C7 and even the updated OLED TVs from last year offer a great gaming experience.

Hi guys! Thanks for the incredible and helpful reviews. Few quick questions:

Are there any artifacts at all when doing 1080p @ 120hz?
Can it do 1080p @ 120hz in 4:4:4?
Is the input lag in 1080p @ 120hz half of what it is @ 60hz?

I'd like to see input lag measurements at 120hz since it seems that more and more TVs are starting to support it.
Thanks again!!

You're welcome, glad you like the site!

There are no artifacts when showing 1080p @ 120 Hz, and no frame skipping either. 1080p @ 120 Hz is actually officially supported in the TV's EDID.
We tested 1080p @ 120 Hz with RGB color and it passed our Chroma 4:4:4 test when the input was set to PC.
We use the industry standard Leo Bodnar tool to test input lag, and it unfortunately only allows testing 60 Hz input lag. We expect the 120 Hz input lag to be lower but likely not half the 60 Hz lag.

Much difference between this and the B6? I know the B6 is cheaper being last year's model. Also do you think the supposed lack of brightness levels on the OLEDs are that big of a deal or a good trade off for true blacks?
There is very little difference between the C7 and B6, mostly in their input lag. We recommend buying whichever is cheaper. Both don't get as bright as high end LED TVs which may be a problem for extremely bright rooms, but for moderately bright rooms and below the other advantages of the OLEDs are more worth it. When watching HDR content in a dark room the OLED's perfect blacks serve to minimize the downside of their lower beak brightness.
2
In regards to your recommendations for the B6 over the newer C7, there seems to be something which you are, IMO, overlooking substantially. The motion judder in the 2016 models was very noticeable to me and unfortunately the reason I went with a different TV instead of an LG OLED. I contacted LG about this issue several times, and it seems they finally corrected it in this years batch. For those of us who are very sensitive to motion judder, and my guess is that as more 4k blurays come out in coming years with 60fps it will be more noticeable to others, too, the issue of judder or not will become very important. The only mass market 4k bluray in 60fps currently is a rather dramatically poor movie called "Billy Lynn's Long Halftime Walk".
Judder is not an issue with 60fps content, as no reverse 3:2 action has to be made. Not all 2016 OLEDs TVs failed This test, but it is true that the C7 is more consistent than the older models. It is important to differentiate judder and the stutter that is inherent to low framerate content such as cinema (see our video series about motion). 60+ FPS motion looks exceptionally smooth on OLED TVs, and the clarity is only bested by good BFI capable televisions.

How significant is the lack of "4k @ 60Hz @ 4:4:4 + HDR" if I plan to use this TV in my living room and occasionally connect a PC for games or watching content? Games are just now starting to support HDR and should hopefully do so more in the future. I'm not sure if having to choose between HDR or 4:4:4 when my computer is plugged in is bad.
By using 4:4:4 with HDR for PC gaming, you will be limiting yourself to 8-bit color depth anyways. Except for very specific cases, most people won't be affected by that limitation.
1
Is the color gamut still locked into the wide setting while in game mode?
Unfortunately, that is still the case.

Much has been discussed regarding image retention on OLED TVs, however most of the discussion centers around bright static images encountered while playing video games or utilizing the TV as a computer monitor. The local Best Buy has an LG B6 OLED on display with severe permanent screen burn that, according to the sales rep, does not disappear after a correction cycle has run. Power is not removed from the set over night, so the normal compensation cycles should be running at shutdown. This TV has been running the same video demo loop for close to a year.

I am an old movie fan and 50% of my viewing consists of 4 x 3 pillarbox content. I realize that you can manipulate the aspect ratio settings to fill the screen, but I prefer to view such in their native format. I would also love to purchase an OLED for the perfect blacks they exhibit. Considering the high percentage of time vertical back bars are displayed during my usage, will this be a permanent image retention issue with OLED sets over time in your opinion?

There is no image retention for black, because an OLED's pixels are off when showing black. After many years of frequently watching content with these black bars you may start to notice that the pixels in the black bars have aged less than in the center, so on normal content the center is dimmer than the sides; however this will probably only happen after decades of intensive use.

Permanent image retention is extremely rare in modern OLED TVs, and is usually covered under warranty if it does happen. Temporary image retention is common, but fades away after watching normal content for 15 minutes or so, because the picture is always changing during normal content.

Greetings. I am a little surprised there's been very little talk about the conspicuous lack of 4K 4:4:4 HDR support with LG's OLED TVs, including their newest. There are a few points to make that I feel are important:

1: For starters, the complete lack of support for the highest-end picture mode should meaningfully ding LG's aggregate score.

2: The review article could stand to explain why the mode is not supported, and whether LG has ever offered comment on this lack. As it is, it is simply "N/A", which begs questions.

3: Anyone buying the most expensive TV on the market is interested in that TV being future proof. HDR is the most important display upgrade of the last year+, and it has two subcategories: Movies and games. Both are getting a major push, but if you're a PC gamer, this expensive TV leaves you wanting, thanks to a shortcoming that is simply not shared by LG's competition. Even ignoring the simple fact of having to sacrifice color resolution, it is not at all reasonable to suggest a PC gamer use 4:4:4 mode when not gaming, only to grab the TV remote and change picture modes whenever it's time to game. For my own part, that one incapacity converts what is otherwise the final word in displays (price notwithstanding) into yet another "close but no cigar."

LG TVs can receive HDR @ 4:4:4 color, but they do not display 4:4:4 properly. You do not need to change picture modes when transitioning from SDR @ 4:4:4 content to HDR @ 4:4:4 content, but HDR @ 4:4:4 will not be displayed properly in any picture mode. We currently don't penalize for not supporting HDR @ 4:4:4, but we may add it to the 'Supported Resolutions' test box and score it when more PC applications and games start supporting HDR.

Will the ABL visibly cause the set to dim during a movie? In your review you stated that "The TV dims over time when showing a static image, but this won't happen during video." and right above that statement "Although the TV gets very dim when showing a pure white window due to its Automatic Brightness Limiter (ABL), it is very bright when showing our real scene test, so most HDR content will be very bright." I am confused, if there is a predominantly white screen during a movie will the tv instantly go from white to a shade of gray? I currently have a VT60 and have never noticed the screen fluctuate from bright to dim and want to know if this will happen on the OLED sets because it would really annoy me if it did. It would never be used as a PC monitor and nearly always used for movies via 4k Blu-ray and some streaming.
The brightness behavior of the C7 is best described by our HDR peak brightness plot, shown here. The dimming over time should never happen during a video because the picture is constantly changing, however the TV does dim when it is shown content with higher average brightness. Our test slides are white boxes in the center of the screen, that cover 2%, 10%, 25%, 50% and 100% of the screen, and represent how bright highlights will be in scenes with higher and higher average brightness. All TVs with local dimming make highlights less bright when shown scenes with high average brightness, partly to save power, but on OLEDs the dimming is more severe. Here is an HDR peak brightness plot for the Z9D, and here is the plot for the C7. In practice however this dimming isn't very distracting when watching movies, because scenes with high average brightness still appear very bright even after dimming, by virtue of the whole screen being bright at once, it's just that highlights in bright scenes are less bright than the highlights in darker scenes.

Why do LG's 2016 120 Hz TVs (B6, C6, UH series) not support 120 Hz input, but the C7 does? Why can't I use all the potential of my panel? Is this a software or hardware limitation? And is it possible to bypass it? Which components block it?
We don't know whether it's a hardware or software limitation that prevents LG's 2016 120 Hz TVs from displaying a 120 Hz HDMI input, but we were unable to make it work even when using a custom resolution on an NVIDIA video card. It's unfortunately common for 120 Hz TVs to not support a 120 Hz HDMI input, no modern Samsung TVs do either.

Thanks for your great review site. Can you comment on two new features for the 2017 LG OLEDs:
1) HDR effect
2) Active HDR with Dolby Vision. Can you explain in simple terms what Active HDR with DV does? If I'm interpreting things correctly, it effectively turns a static HDR source (such as HDR 10) to an equivalent of a dynamic source like Dolby Vision. In other words, it "upgrades" HDR10 content to something closer to a Dolby Vision level of content.

Are these two new features valuable in your opinion?

The HDR Effect picture mode attempts to turn SDR content into HDR content, by radically changing the picture's gamma curve and oversaturating colors near the edge of the SDR gamut. This is similar to Samung's "HDR+ Mode". We don't recommend using it as it makes content quite different from what the creator intended, but some people may prefer it.

It's unclear what Active HDR does, most of the information about it is just marketing jargon. There's no setting on the C7 to disable it so it likely doesn't do much.

Hi, As far as web surfing with the 3.0 b6 or 3.5 webOS c7, does the magic remote work like a mouse with the web browser? In other words, can I surf the internet and click on any link using the magic remote like a mouse? Thanks, Alan
Yes, the magic remote functions just like a traditional mouse cursor making it a much better experience than other Smart TV web browsers.

Can you confirm if this signal is able to have a refresh rate of 120hz when connected to a pc/mac via HDMI? Thank you!
We do not have a mac to verify this, but there is no reason for it to not be supported if the computer has an HDMI 1.4 or DisplayPort 1.2 connection, especially since it's a supported resolution from the start and doesn't need to be created as a custom one.

First, thank you for your great reviews. I've been wanting to buy an OLED TV for a long time now. Unfortunately, because of the way my TV room is set, I can't go beyond a 49-inch TV set. So I was wondering if you had any idea whether 49-inch OLED TVs will ever be released. It is my understanding that right now production is still constrained and that LG is concentrating on the larger screen sizes. But is there any hope for smaller OLED TVs in the near future? Or maybe a better question would be: would a 49-inch OLED TV bring significant picture improvements over the currently best-rated LED offering (the Sony XBR49X900E in this case), or does the smaller screen size make the point moot (much like 40-43-inch screens do not really seem to improve with Full-LED vs Edge-Lit)? I'm looking forward to hearing from you. Best regards.

We haven't heard LG or Sony's plans but it's unlikely smaller OLEDs will be released this year, perhaps not next year either; partly because OLEDs are all high end TVs and high end TVs are sometimes not offered in smaller sizes.

Better picture quality does not become less relevant with smaller TVs if you're sitting at a proper distance (6.9 feet for a 49" TV). Though local dimming on smaller TVs is usually worse because they have fewer zones, so full array is less worth it as you mentioned, but often still beneficial. The benefits of OLED TVs are still very relevant at smaller sizes. However it's not likely worth waiting until smaller OLEDs get released because the current top LED TVs are still very good for most use cases, and are significantly cheaper. The Sony XBR49X900E and Samsung 49KS8000 (if you can still find one) are our current top picks for TVs in this size range, buy whichever is cheaper.

This is a general OLED question (I own the 55B6). Do you guys say that your OLEDs show a perfectly black screen (no glowing at all in a completely dark room) when fed a 100% black/0% white/0 IRE image? I find that on "black" screens from calibration Blu-rays and other sources like black screens on YouTube (built-in app and Apple TV), my OLED glows very slightly. Its a very, very, very dark gray, but certainly not "off" black. The glowing is a little brighter in the corners. I use ISF/Dark mode. My OLED light is set to 80. Brightness is 52. Contrast is 84. Gamma is 2.4. All other picture enhancements OFF. Now, when the Blu-ray player is changing chapters, loading the disc, etc., I will get a completely black screen (looks OFF) for a couple seconds until the actual image is being displayed. I'm confused. Is what I'm seeing normal? Am I not understanding what is written in your testing? Thanks!
It's probably because brightness is set to 52. An OLED will show true black if the settings are set correctly. We tested our C7 in a completely dark room while using your settings and when brightness was at 51 the TV showed true black, but when brightness was 52 black became a very dark gray. We recommend brightness be set to 50, which is default. You can see all our recommended settings for the B6 here.

I rely on the smart features a lot, since I have cut the cord with cable. Is the WebOS 3.5 significantly better than last year's 3.0 in the B6? Is it something worth considering the price difference? Or would you recommend the Sony x900e for apps?
We tend to prefer WebOS over Android, and there aren't any significant differences between 3.0 and 3.5. Some things have been re-arranged and moved about in the menus, but no major smart feature was added.
0
Does this TV support HDR with the built-in youtube app? The B6 does not. Also, does this version support HLG? There have been comments made by LG that both of these issues will be resolved by firmware but lately, there have been comments from LG stating otherwise. This may be a real reason to get the 2017 model and a warning for future LG buyers that LG will only support firmware updates for one year. Can we expect to be abandoned?
The C7 does support HDR in the built-in Youtube app as well a HLG. It's unclear whether or not support for these older models is going to be discontinued, but HDR on Youtube is probably waiting on Google to add support for these models.

I picked up a free EF9500S from a buddy that gets floor model sets from big box stores. Anyway it was free because it had some burn-in from the store displaying "LG OLED" for 6 months for 12 hours a day. The burn-in doesn't go away. Obviously I'm OK with it since it was free. But what I'm wondering is if the wife has FOX News on all day, will that burn-in? We had a Samsung PN64F8500 that did develop burn in.

I'm wondering if you guys have heard about any permanent burn-in with OLEDs. I realize my free TV was extremely abused. Under normal circumstances, even if the TV is on FOX or another channel with a static display is it possible to get permanent burn in?

We have heard of a few cases of permanent burn-in, but they're usually extreme cases such as in Best-Buy show rooms, and when the TV's burn-in compensation program isn't working. Most LG OLEDs have a program that runs invisibly for a few hours after the TV is turned off that clears burn in. If the TV is never turned off or this program is defective, then the TV may get permanent burn in. You can also run this program manually to see if it helps with your burn in.

About the FOX News, as long as the TV is turned off at the end of the day it shouldn't develop any more permanent burn in; however if you watch FOX News for a few hours then change to something else you may see temporary burn in of the FOX News logo, but this should disappear after a couple minutes of watching normal content.

Love your reviews and the effort you put into them! I'm confused: How does this OLED compare to Samsung KS8000's native black uniformity? Samsung's KS8000 native black is rated 9.9 on your reviews, and the OLED as perfect 10, which means it's pretty close to perfection. In that case, why would you need to turn on local dimming at all on the KS8000? Seems like the local dimming makes the blacks worse on the KS8000? And why would the OLED's black worth the extra $$$?
The uniformity is great on the KS series, but it's important not to confuse that with the depth of the blacks which can be found in our contrast ratio measurement. If placed in a very dark room, OLEDs will not light up black sections at all, while good LCD TVs will look like a very dark gray. LCDs are constantly illuminated if they do not have some sort of local dimming, so they rely on the panels ability to block light effectively. You can learn more about the differences between LED TVs and OLEDs here. Not all local dimming is the same also, and a lot of TVs often do more bad than good with this feature on.

Does 1080p @ 120 Hz + HDR on Windows 10 give a really bright gamma? My 55C7 seems to be having this problem. 60 Hz HDR is fine though, as is 120 Hz SDR.
Confirmed with Shadow Warrior, HDR, 120 Hz, in and out of PC mode. With HDR at 120 Hz the TV shows that it's playing HDR content but it appears to follow the SDR gamma curve rather than the HDR PQ curve. The game is still displaying a picture made for the PQ curve, so everything looks off. The review has been updated to state that HDR does not work properly at 120 Hz.

The EU version, at least in the Netherlands, does not have composite in.
Thank you for letting us know. We only review US models but do expect the international variants of the C7 to have the same performance and picture quality, but with different inputs.
