The LG B9 OLED is a remarkable TV with excellent picture quality that displays perfect blacks. It has excellent wide viewing angles, good SDR peak brightness, and handles reflections well. This TV has a wide color gamut and decent HDR brightness, but the aggressive ABL can become bothersome. Motion looks crisp thanks to the nearly instantaneous response time, and the TV has a motion interpolation feature that can help minimize stutter in movies. Gamers will enjoy a responsive gaming experience thanks to the very low input lag, but unfortunately, just like all OLED TVs, it has the possibility of developing permanent burn-in.
This is an excellent TV for mixed use. It has outstanding dark room performance thanks to its perfect blacks. It can also fit nicely in a bright room thanks to its good SDR peak brightness and excellent reflection handling. It delivers very crisp motion and the excellent gray uniformity and wide viewing angles make it an excellent choice for enjoying sports with a group of friends. Gamers will appreciate the low input lag.
The LG B9 is an excellent TV for watching movies in a dark room. It has perfect blacks and perfect black uniformity that delivers an amazing dark room performance. The gray uniformity is also excellent and the TV can display judder-free movies. Although its fast response time creates stutter, the TV has an optional motion interpolation feature that can help minimize it.
The LG OLED B9 is a remarkable TV for watching TV shows in a bright room. It has good SDR peak brightness and can handle reflections well, so you can place it in a bright room without issue. The image remains accurate for wide viewing angles so you can easily do some house chores as you don't have to sit straight in front to enjoy your favorite TV show. LG content store has an abundance of apps to help you find the right one for you.
This is an impressive TV for watching sports. The nearly instantaneous response time, the wide viewing angles and the excellent gray uniformity make it a great choice for sports fans. You can place it easily in a fairly bright room without worrying about reflections thanks to its excellent anti-reflective coating. Just sit back and enjoy your favorite game.
The LG B9 is a remarkable TV for playing video games. The response time is nearly instantaneous and the TV's input lag is extremely low. These are great for gamers who can also enjoy a smoother gaming experience thanks to the TV's support for HDMI Forum VRR. It has an Auto Low Latency Mode, so you don't have to remember to switch to 'Game' mode each time you want to play a game.
The B9 is an excellent TV for watching movies in HDR. The TV has decent HDR peak brightness and a wide color gamut that delivers vivid colors. It displays perfect inky blacks thanks to its OLED technology. Unfortunately, the TV's automatic brightness limiter (ABL) causes the brightness to fluctuate with different content, which can become bothersome.
Excellent TV for gaming in HDR. It has a nearly instantaneous response time and a very low input lag which offers a very responsive gaming experience. It has an excellent wide color gamut and decent peak brightness in HDR. Unfortunately, the brightness changes with different content, and this might bother some people.
The LG OLED B9 is a great TV for use as a PC monitor. It displays proper chroma 4:4:4 in most resolutions so text looks clear. It has a very low input lag and an extremely fast response time that delivers fast-moving content with almost no blur. Unfortunately, just like all OLED TVs it runs the risk of permanent burn-in and this can be an issue if you use it as a PC monitor for extended periods of time.
The LG OLED B9 is a high-end 2019 TV. It replaces the 2018 LG B8 OLED. Since picture quality is very similar among all OLED TVs, the additional features and the design is what differentiates them. The main competitors are the LG C9 OLED, LG E9 OLED, Sony A9G OLED, and Sony A8G OLED. For LED competitors, the Samsung Q80R and the Sony Z9F can be considered the main ones.
The design of the LG B9 is outstanding. Overall, it resembles the design of the 2018 LG B8, although this year's model feels a bit less premium. This TV has a plastic stand, whereas the previous model has a metal one. The stand supports the TV well, but can't prevent all wobble. The back is plain and the TV is thin, just like most LG OLEDs. The build quality is excellent, and you shouldn't have any issues with the TV.
The stand of the B9 OLED is plastic and looks very similar to last year's B8 which, however, was made of metal. The B9's stand allows more wobble than last year's model.
Footprint of the 55" TV stand: 21.9" x 9.3".
The back of the B9 is plain. The upper part is made of metal, and the bottom is plastic and houses the electronics. Some of the inputs are facing sideways and some are facing outwards, which can get in the way if you wall-mount the TV. Cable management is serviced with the aid of a little clip on the back, very similar to the B8.
Just like most OLED TVs, the B9 has very thin borders that aren't distracting. There is a very small gap between the edge of the bezel and the start of the pixels.
The LG B9 is a very thin TV. It's thicker at the bottom where the electronics are housed, but even then it's still thin and won't stick out much if you wall-mount it.
The B9 delivers perfect blacks, just like all OLEDs. It can switch off individual pixels, which creates an effectively infinite contrast ratio.
The LG OLED B9 doesn't need a local dimming feature since there is no backlight. Each pixel is self-emitting and can turn off or dim itself. In a dark room, this looks great, with no visible blooming around bright objects. Subtitles are also displayed perfectly.
The LG B9 has good peak brightness with SDR content and is suitable for a fairly bright room. Its brightness is in the same ballpark as the LG E9 and is a little brighter than last year's LG B8. Its Automatic Brightness Limiter (ABL) is aggressive, similar to the E9, and it dims the screen significantly when larger areas of the screen get bright.
This TV, just like the C9 and the E9, has a new Peak Brightness setting that adjusts how the ABL performs. If you set it to 'Off', most scenes are displayed at around 266 cd/m² and there is no real variation in brightness according to the scene content, which is great. Increasing this setting to 'Low', 'Med', or 'High' increases the peak brightness of small highlights.
We took our measurements after calibration in the 'Expert (Dark Room)' Picture Mode, with Gamma set to '2.2', Color Temperature set to 'Warm2', Peak Brightness set to 'High', and OLED Light set to '100'. These were also the settings that gave us the brightest image.
The HDR peak brightness of the OLED B9 is decent. It's in the same ballpark as last year's LG B8, but can't reach the brightness levels of the C9. The ABL is a little less aggressive than the ABL found on the E9 and the C9, but you'll still notice the change in brightness with different content.
The HDR brightness measurements were taken in 'Cinema' mode, with OLED Light set to '100,' Peak Brightness set to 'High', and Color Temperature set to 'Warm2'.
Different picture modes and color temperatures will produce different results. We measured the 2% window at 767 cd/m² in the default 'Vivid' (HDR) Picture Mode.
The gray uniformity on the B9 is excellent. There's hardly any dirty screen effect, which is great for sports fans. The uniformity is just as good in near-dark scenes. Just like the E9 and other OLED TVs, you might notice some very faint horizontal and vertical lines when you're displaying almost black scenes in a pitch-black room. It's unlikely that you'll notice this under other conditions.
The LG B9 has outstanding viewing angles. The brightness and black levels are good even at very large angles off-center. Just like the E9 and the C9, colors shift and lose accuracy at smaller angles. They're still better than most LED TVs, but not as good as VA panel TVs that use a special filter like the Samsung Q80R of the Sony Z9F.
Perfect black uniformity on the B9, as expected from an OLED TV.
The B9's reflection handling is outstanding. Just like on the C9 and the E9, the glossy filter diminishes reflections by preventing them from scattering across the screen. You should have no issue placing this TV in a room with many light sources.
The purple tint you see on the image is the result of the anti-reflective coating and is also found on other TVs like the E9 or the Q8FN.
The accuracy of the B9 with its pre-calibration settings is poor. Most people will notice the inaccuracies in the pure whites, as the color temperature is warm with a yellowish tint. Enthusiasts, however, will also notice some inaccuracies in the colors. The gamma follows the target well, but some brighter scenes don't have the proper brightness. If out-of-the-box color accuracy is important to you, check out the LG BX OLED.
Great upscaling of 480p content, like from DVDs, without obvious upscaling artifacts.
Like all other OLEDs, the B9 uses 4 sub-pixels, but all 4 are never used at the same time. This image shows the white, blue, and red sub-pixels. You can see the green sub-pixel in our alternative pixel photo.
The B9 has a wide color gamut and can deliver vivid colors with HDR content. The TV follows the target PQ curve closely (although some very dark scenes are crushed) until it rolls off relatively sharp near the TVs peak brightness. In 'Game' mode, the EOTF is nearly identical.
If you find HDR too dim, the TV has two options to help you make it brighter. Check out what to do on the TV settings page here.
The color volume of the B9 is good. It's significantly better than last year's LG B8 and better than this year's E9 and C9, although this could be due to panel variance. Due to its WRGB pixel structure, the TV can produce bright whites but can't deliver bright saturated colors. The perfect contrast ratio, on the other hand, allows the TV to produce dark saturated colors with no issues, unlike many LED TVs.
The LG B9 has good gradient handling, but not on par with the rest of the LG TVs. Some banding is evident not only in our test pattern but also with normal content. This was not expected from the B9 and we had to confirm the results three times.
Just like the C9, this TV has a Smooth Gradation feature, which, however, can't remove banding in our test photo. With normal content, when Smooth Gradation is set to 'Low', it doesn't do much, so you should set it to 'High' to see significant improvement. However, then you risk losing some fine detail. If you want an OLED TV with better gradient handling, check out the Sony A9S OLED.
Although there are no signs of temporary image retention on the panel of our B9, some panel variation is to be expected. On the E9 we tested this year, we observed some faint temporary image retention.
This test is only indicative of short term image retention, and not the permanent burn-in that may occur with cummulative longer exposure to static images. We're currently running a long-term test to help us better understand permanent burn-in. You can see our results and read more about our investigation here.
Update 11/01/2019: Updated text to include our stance on burn-in.
Although we don't expect most people who watch varied content to have any issues, OLED TVs, such as the LG OLED B9 do have the possibility of experiencing burn in.
This TV has three features to help mitigate burn-in. We recommend enabling the Screen Shift option, and setting Logo Luminance Adjustment to 'Low.' There is also an automatic pixel refresher that can be run manually if needed.
You can read about our investigation into this here.
The response time is nearly instantaneous and this is excellent. Motion looks crisp and there is almost no blur trail behind fast-moving content. This, however, causes stutter on movies and some people might be bothered.
Update 06/25/2020: We incorrectly stated that this TV was flicker-free, it's not. Although the flicker isn't at all noticeable, there is a slight dip in brightness every 8ms.
The LG B9 doesn't use PWM to dim the screen. This helps motion appear smoother, but results in some persistence blur. The slight dip in brightness that you see in the graphs appears every 8ms and coincides with the TV's refresh rate. This should not be noticeable.
Update 11/26/2019: A recent firmware update fixed the black frame insertion feature on our B9. It's now working properly.
The LG B9 has an optional black frame insertion feature, known as OLED Motion, which can help improve the appearance of motion. Like the C9, enabling this option always causes judder when watching 24p content, like movies.
The LG B9 has a motion interpolation feature and can interpolate content up to 120fps, which is excellent. However, just like the E9, the TV continues to interpolate even when it displays very busy scenes and this creates many artifacts that can become bothersome.
See here for the settings that control the motion interpolation feature.
The LG B9 has stutter due to the nearly instantaneous response time that holds each frame on the screen for longer. This is especially noticeable in movies' slow panning shots. You can use motion interpolation to minimize it.
The LG B9 can display 24p content without judder no matter the source.
See our recommended settings to remove judder here.
Update 06/12/2020: The B9 is now compatible with recent NVIDIA G-SYNC graphics cards, and is officially certified as G-SYNC compatible. We updated the VRR range, as we're now able to test this accurately with our RTX 2070.
The LG B9, just like the C9, has a native 120Hz refresh rate. It only supports HDMI Forum's new HDMI-VRR format. Currently, this is only supported on new Xbox Ones, or with a recent NVIDIA graphics card. The B9 is officially supported by NVIDIA's G-SYNC compatible mode, which is enabled automatically when connected to a recent NVIDIA graphics card.
Update 06/12/2020: The B9 is now compatible with recent NVIDIA G-SYNC graphics cards, and is officially certified as G-SYNC compatible. We tested the VRR input lag, as we're now able to test this accurately with our RTX 2070.
The LG B9 now supports an Auto Low Latency Mode to save you the hassle of having to switch to 'Game' mode each time you want to play a game. See our recommended settings for Gaming.
The LG B9 supports most of the common resolutions we test for. Just like the other LG OLEDs we tested this year, the B9 supports 1440p resolutions. It can display proper chroma 4:4:4 in all of the supported resolutions except 1080p @ 120Hz. To display proper chroma 4:4:4, the input icon must be changed to 'PC' from the Home Dashboard, and the HDMI ULTRA HD Deep Color setting must be enabled for the port in use. Some of the supported formats require that the HDMI ULTRA HD Deep Color is enabled to display properly.
The LG B9 is advertised to support HDMI 2.1, but there weren't any HDMI 2.1 sources when we tested it. We can't test it with an HDMI 2.1 source because we've since sold the TV.
This TV supports eARC when connected to a compatible AV Receiver, which allows it to send higher quality DTS:X and Dolby Atmos via TrueHD sound from an external device to your receiver. Like the 2018 LG OLEDs, it also supports DTS and Dolby Digital passthrough to a standard ARC receiver.
This TV has a decent frequency response. The low-frequency extension is decent, similar to the C9, but slightly worse than last year's B8. This results in a bass without much thump or rumble, but with a decent amount of punch and body. The frequency response above the TV's LFE allows the TV to deliver clear dialog. Finally, this TV gets fairly loud without too much pumping and compression artifacts under maximum load, which is especially good for noisy areas.
The LG OLED55B9PUA has decent distortion performance. The overall amount of THD produced at 80dB SPL is good and remains decent at maximum volume. However, it could sound a little harsh and impure when pushed to the limit.
The interface is smooth and easy to use once you get used to it. We did not encounter any bugs in the interface.
The LG B9 contains ads and suggested content just like all other LG TVs we've tested this year. Unfortunately, there is no way to opt-out of either.
The LG B9 gives you access to LG's store, which is has a very large number of available apps. The most common apps are pre-installed, but you can always download more from the store. Just like the C9, the B9 supports casting from your smartphone or tablet.
The LG B9 has the same remote as the C9 and the E9. It has the same new added features, like the option to program the remote to work as a universal remote with other devices over IR. This is very similar to Samsung's OneRemote feature and is very handy when the other device doesn't support HDMI-CEC.
The remote can also be used as a mouse pointer which makes it easy to navigate the interface, once you familiarize yourself with it. Finally, the B9 allows some voice control of the TV and searching within some apps like YouTube and Netflix.
We tested the 55" B9 (OLED55B9PUA), and we expect our results to be valid for the 65" (OLED65B9PUA) and the 77" (OLED77B9PUA) models as well.
If someone comes across a different type of panel or if their LG B9 OLED 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.

The B9 we reviewed was manufactured in June 2019.
The LG CX OLED is a bit better than the LG B9 OLED. The CX can get brighter in HDR, it has much better out-of-the-box color accuracy, and its BFI features works at 120Hz. The B9 has slightly wider viewing angles and the gray uniformity is better, but this could be due to panel variances.
The LG B9 OLED and the LG B8 OLED have very similar picture quality overall. The B9 is more future-proof, as it supports some great new features including HDMI 2.1, eARC, and HDMI Forum's variable refresh rate technology, which is currently only supported by the Xbox One.
The LG B9 OLED and the Samsung Q80/Q80R QLED have different panel types, each with their advantages and disadvantages. The B9 has an excellent dark room performance thanks to its perfect blacks. The Q80R can get significantly brighter and can fight the glare of a very bright room. The B9 has better gray uniformity and better viewing angles, but it also has a risk of permanent burn-in when exposed to static content, something that doesn't happen with the Q80R.
The LG B9 OLED is a better TV than the Samsung Q70/Q70R QLED. Thanks to the OLED's ability to individually turn off pixels, it has perfect black levels. The B9 also has a wider color gamut, much better viewing angles, gray uniformity, and reflection handling. On the other hand, the Q70R can get brighter, has better out-of-the-box color accuracy, and doesn't have the same risk for permanent burn-in that the OLED does.
The LG BX OLED and the LG B9 OLED are very similar TVs. The B9 gets brighter, and it has better gradient handling, while the BX has much better out-of-the-box color accuracy, and its Black Frame Insertion feature flickers at 120Hz. Other than that, the two TVs are built the same way and have the same stand.
The LG B9 OLED is a better TV than the Samsung Q80T QLED. The LG is an OLED TV that can turn off each pixel individually, producing perfect blacks and delivering stunning picture quality, especially for watching movies in the dark. The LG also has a near-instantaneous response time and much better viewing angles. That said, the OLED panel on the LG also runs the risk of permanent burn-in, though this likely won't be an issue for most people who watch normal, varied content.
The LG B9 OLED is a significantly better TV than the Sony X950H. Due to OLED's emissive technology, the LG has an infinite contrast ratio that can produce perfect blacks, without any blooming caused by local dimming. Viewing angles are better on the LG, and so are black and gray uniformity. Also, the LG has near-instantaneous response time, much lower input lag, and it supports VRR. However, the Sony can get much brighter to deliver a better HDR experience, and it's much more color accurate out of the box.
The LG B9 OLED and LG C8 OLED are very similar. The B9 has no signs of temporary image retention, but this varies between units. The B9 is also more future proof at it has 4 HDMI 2.1 inputs, supports eARC, and supports the HDMI Forum variable refresh rate technology, which is great for nearly tear-free gaming.
The LG B9 OLED is a better TV than the Samsung Q60/Q60R QLED. It has perfect blacks, thanks to its OLED screen, and has much wider viewing angles. It also does a much better job at handling reflections, can get brighter for HDR content, and has a much wider color gamut. On the other hand, the Samsung has much more accurate colors out-of-the-box, can get brighter for regular content, and doesn't run the risk of permanent burn-in if you watch a lot of static content for extended periods.
The LG B9 OLED and the Samsung Q90/Q90R QLED use different panel types, each with their advantages and disadvantages. The B9 has perfect blacks thanks to its OLED panel and delivers a better dark room performance. The Q90R can get significantly brighter and is more suitable for a very bright room. The B9 has better gray uniformity and better viewing angles, but also has a risk of permanent burn-in when exposed to static content, something that doesn't happen with the Q90R.
The LG B9 OLED is a better TV than the Sony X950G. The B9 has perfect black levels thanks to OLED's ability to turn off each individual pixel. It also has much wider viewing angles, better reflection handling, better motion handling, and a wider color gamut. On the other hand, the Sony X950G has a much higher peak brightness, and can better display color gradients.
The LG B9 OLED is a bit better than the Sony A8G OLED. The B9 has HDMI 2.1 on all four HDMI ports, as well as eARC. The B9 is better for gaming as it has a much lower input lag and supports HDMI Forum's new variable refresh rate technology, which is great news if you have an Xbox One.
The LG B9 OLED is a much better TV than the Sony X900F. The OLED has perfect, inky blacks thanks to its individually backlit pixels. It also has better gray and black uniformity, much wider viewing angles, much better reflection handling, a wider color gamut, much better motion handling, and much lower input lag. On the other hand, the Sony can get much brighter with both SDR and HDR content and has much more accurate colors out-of-the-box.
The LG B9 OLED is a much better TV than the LG SM9000. Thanks to its OLED panel, the B9 has perfect blacks and excellent viewing angles. It also has much better gray uniformity than the SM9000 and does a better job handling reflections. The B9 is also a better choice if you watch a lot of sports or play a lot of games as it has much better motion handling. On the other hand, the SM9000 has more accurate colors out-of-the-box. The SM9000 also doesn't run the risk of permanent image retention or burn-in, like the OLED panel on the B9 does. This likely won't be an issue for most OLED owners who watch normal, varied content, but can be a concern if you watch a ton of static images.
These two TVs have different panels, each with its advantages and disadvantages. The LG B9 OLED is an OLED TV that delivers an excellent performance in any use, but has the risk of burn-in with prolonged exposure to static content. The Samsung The Frame 2019 doesn't suffer from burn-in, but has worse picture quality, and its viewing angles are poor. On the upside, it's designed to be flush wall-mounted and stay on for long periods.
