The LG B3 OLED is a mid-range OLED TV, replacing 2022's LG B2 OLED, and sits between the LG A3 OLED and the LG C3 OLED in LG's 2023 lineup. It uses LG's α7 AI Processor Gen6 for its image and audio processing and supports Dolby Vision HDR as well as Dolby Digital, Dolby Atmos, and DTS audio formats. It has four HDMI ports, two of which carry HDMI 2.1 bandwidth capable of up to 4k @ 120Hz, including Dolby Vision gaming at up to 120Hz. The TV is compatible with every variable refresh rate (VRR) technology for nearly tear-free gaming, has LG's Game Optimizer gaming interface, and has Auto Low Latency Mode (ALLM) support. It comes with version 23 of LG's webOS smart platform and works with the Amazon Alexa, Apple Homekit, and Google Assistant smart ecosystems, as well as Apple Airplay2 for wireless streaming. It's available in a few sizes, from 55 to 77 inches.
The LG B3 is an excellent TV overall. It's remarkable for watching movies in dark rooms thanks to its near-infinite contrast ratio with perfect blacks, with most colors looking bright and vibrant. If you watch shows or sports in bright rooms, it's impressive as it has incredible reflection handling to fight glare from a few light sources, but it doesn't get bright enough to fight glare in brighter rooms. It's incredible for gaming with HDMI 2.1 bandwidth on two ports, variable refresh rate (VRR) support to reduce screen tearing, very low input lag, and a near-instantaneous response time for smooth motion. It's also fantastic to use as a PC monitor, but OLEDs risk permanent burn-in when exposed to the same static elements over time.
The LG B3 is great for watching TV shows in well-lit environments. Its reflection handling is incredible, although it's not bright enough to fight a ton of glare. It also has a wide viewing angle that makes the image look consistent from the sides, so you can watch shows with the entire family sitting around the TV. The built-in webOS smart platform has a ton of apps available to download, and its image processing is very good overall, so shows look great no matter their source.
The LG B3 is amazing for watching sports. Fast-moving sports look smooth with minimal motion blur, and it has great gray uniformity that makes playing surfaces look uniform. It has a wide viewing angle, making it an ideal choice for wide seating areas as people sitting to the sides see a consistent image. It has incredible reflection handling if you have a few lights around, but it doesn't get bright enough in SDR to fight a ton of glare, so it's not the best choice for very bright rooms.
The LG B3 is incredible for gaming. It has many gaming features, like HDMI 2.1 bandwidth on two ports and variable refresh rate (VRR) support, that make it fully compatible with recent consoles and PC graphic cards. It also offers a quick and responsive gaming experience thanks to its low input lag and near-instantaneous response time. Unfortunately, its SDR brightness is just okay, and it struggles to look bright and vibrant in very bright rooms, even with its incredible reflection handling. However, it's remarkable for dark room gaming as it has a near-infinite contrast ratio that produces deep blacks, with no blooming around bright objects.
The LG B3 is excellent for watching HDR movies. It looks incredible in dark rooms as it displays deep and inky blacks without any blooming. It displays a wide color gamut in HDR, but its tone mapping is off, so colors don't look very accurate. It also has okay HDR peak brightness, enough to make some highlights stand out, but it doesn't get bright enough to deliver a truly satisfying HDR experience with bright and vivid colors. Its image processing is very good overall, so low-bitrate content from streaming services is mostly free of noticeable digital artifacts, like macro-blocking.
The LG B3 is fantastic for HDR gaming. It delivers incredible gaming performance thanks to its variable refresh rate (VRR) support, HDMI 2.1 bandwidth on two ports, quick response time, and low input lag. It's also fantastic for dark room gaming as its blacks are deep and inky, and it displays bright objects without any blooming. Its HDR experience is excellent thanks to its dark room performance, with most colors looking bright and vibrant, but some bright highlights don't truly pop.
The LG B3 is fantastic to use as a PC monitor. Thanks to the low input lag and incredible response time, your mouse movements and keyboard inputs feel extremely responsive, with no noticeable motion blur. It also has a wide viewing angle that makes the image remain consistent if you sit too close, and the reflection handling is incredible if you want to use it in a room with a few lights around, although it's not bright enough in SDR for very bright rooms. Sadly, OLEDs risk permanent burn-in when exposed to the same static elements over time, like from a PC's user interface.
We tested the 65-inch LG B3 (OLED65B3PUA), and the results are also valid for the 55 and 75-inch models. Note that the last three letters in the model number (PUA in this case) vary between retailers and individual regions, but there's no difference in performance. Models ending with AUA, like the LG 65OLEDB3AUA, are Costco/Sam's Club variants but are otherwise identical, although they are advertised as having Wi-Fi 6E, while LG's website advertises the PUA models as having Wi-Fi 5.

The LG B3 is an excellent OLED TV. It delivers deep blacks, and it has advanced features for gamers. The B3 is a slight step down from the LG C3 OLED in terms of peak brightness, so if you watch a lot of HDR content, you might want to spend just a bit more for the C3. The Sony A80L/A80CL OLED and the Sony A75L OLED are both very similar to the B3, and while the Sony TVs have better image processing, the LG is much cheaper and is the better choice for most people. Ultimately, the LG B3 is a great entry point into the OLED market and is one of the best bang-for-the-buck OLEDs on the market.
The LG C2 OLED and LG B3 OLED are similar TVs with similar feature sets. The C2 gets slightly brighter in HDR but much brighter in SDR, so it pops more in most content. It also has four full HDMI 2.1 bandwidth ports, while the B3 is limited to two, with one of them also doubling as the eARC port. Inversely, the B3 has better image processing, so low-resolution or low-bitrate content looks better. The B3 also passes through advanced DTS audio formats, making it a better choice for a home entertainment setup.
The LG B3 OLED is the successor to the LG B2 OLED, and while they're both extremely similar, the newer B3 is better in a few ways. The B3 has much better image processing than its predecessor and can pass through advanced DTS audio signals, making it a better option for home entertainment setups. Inversely, the B2 gets brighter in SDR, so SDR content like TV shows and sports pop more on it than on the B3.
The Samsung S90C OLED and LG B3 OLED are both amazing TVs, and while the LG has a few features that the Samsung doesn't have, the S90C is the better TV overall. The Samsung gets much brighter in HDR and SDR, with a wider color gamut and better color volume, so all content looks significantly more vibrant on the Samsung. It also has four full HDMI 2.1 bandwidth ports, all capable of up to 4k @ 144Hz, making it the better TV for gamers. The B3 does have better image processing, supports Dolby Vision HDR, and passes through DTS audio formats, making it enticing for home entertainment fans.
The Sony A80L/A80CL OLED and the LG B3 OLED are very similar OLEDs with similar features and performance. The Sony gets a bit brighter in HDR and has better image processing, so it's the better choice for movie aficionados. Alternatively, the LG has slightly lower input lag, 1440p support, is a bit brighter in HDR when in Game Mode, and can do Dolby Vision gaming at 120Hz, so it's the better option for gamers.
The LG C3 OLED and LG B3 OLED are similar TVs with nearly identical feature sets, but the C3 is better overall. The C3 gets much brighter in HDR and SDR, has better image processing due to its better 4k processor, and has four full HDMI 2.1 bandwidth ports. Inversely, the B3 has two HDMI 2.1 bandwidth ports, one of which also doubles as the eARC port, so you'll need to buy an HDMI 2.1 switch if you have multiple HDMI 2.1 devices.
The LG B3 OLED and the Sony A75L OLED offer very similar picture quality overall, but the Sony is slightly better. The Sony gets slightly brighter, and it's powered by Sony's industry-leading picture processing, which delivers better upscaling and low-quality content smoothing.
The TV has an elegant style similar to other LG OLEDs. It has a thin silver border with slim bezels. Otherwise, it has a center-mounted stand with a thin panel and a mainly gray body.
The center-mounted stand has a small footprint and keeps the TV stable, but it doesn't prevent all wobble. However, it doesn't take the TV long to settle after it starts wobbling, so it isn't an issue in practice. It's made from plastic even though it looks like metal. The stand lifts the TV about 2.1" above the table, so placing a soundbar in front of it blocks part of the screen.
Footprint of the 65" stand: 22" x 9.5"
The LG B3 OLED has a metal back panel, and the part housing the inputs is plastic with a brushed aluminum look. Some of the inputs are side-facing and easy to access with the TV wall-mounted, but the back-facing ones are harder to reach, and you can't make the TV sit flush against the wall if you have cables plugged into the back. Unfortunately, the back-facing ports are the TV's two HDMI 2.1 bandwidth ports.
There's a clip for cable management to help keep your setup clean.
The TV has excellent build quality. It's well put together, and there aren't any obvious quality control issues. It has a solid metal back panel, and while the plastic portion with the inputs does flex quite a bit when pushed, it's not a problem during use. Despite the stand's small size, it still supports the TV well, and there's only a bit of wobble from front to back.
The LG B3 OLED has a nearly infinite contrast ratio like every other OLED. As each pixel can individually control its own brightness due to OLED's self-emissive technology, you can have super bright highlights next to pixels that are completely off, leading to perfect blacks with no blooming or haloing.
Since pixels can be completely turned off next to pixels that are lit up to their maximum brightness, the blacks surrounding bright elements are perfect and don't have any blooming.
As with other OLED TVs, this TV doesn't have a backlight, but its self-emissive pixels give it the equivalent of a perfect local dimming feature with no zone transitions. We still film the zone transition video on the TV so you can see how the screen performs and compare it with a TV that has local dimming.
There's no difference in dark scene behavior between the calibrated picture modes and Game Mode.
The TV has decent HDR peak brightness. It's enough to make some small highlights stand out, but its overall HDR experience isn't as good as other OLEDs, like the LG C3 OLED.
These measurements are after calibrating the HDR white point with the following settings:
Here are measurements with Dynamic Tone Mapping set to 'On':
The LG B3 has decent HDR peak brightness in Game Mode, although it's slightly dimmer than in the other calibrated picture modes.
These measurements are after calibrating the HDR white point with the following settings:

The PQ EOTF tracking of this TV with HDR10 content is nearly flawless. There are a few minor bumps along the way, but most scenes are displayed at exactly the brightness level the content creator intended. There's a sharp cutoff at the TV's peak brightness with content mastered at 600 and 1000 nits, causing a loss of bright details in extremely bright scenes. Inversely, the TV slowly rolls off when it gets near its peak brightness for content mastered at 4000 nits, preserving fine details in the process. You can also see how different Dynamic Tone Mapping (DTM) settings impact the EOTF here.
The TV has okay SDR peak brightness. It's enough to fight glare if you have a few small lights around, but scenes with larger areas of bright colors, like in hockey or basketball, are dimmer due to the Automatic Brightness Limiter (ABL).
These measurements are after calibration with the following settings:
Setting Peak Brightness to 'Off' reduces the aggressiveness of the ABL but also lowers the peak brightness to about 260 cd/m² in most scenes. Setting the input to Game Mode or PC Mode, or setting the 4:4:4 Pass Through option to 'On', locks the Peak Brightness option to 'Off'. Here are measurements with the setting disabled:
The LG B3 has an excellent HDR color gamut. It has fantastic DCI-P3 coverage, which is the most common color space used in most HDR content, and has good coverage of the wider Rec. 2020 color space. However, tone mapping is off with both, resulting in inaccurate colors, especially with green between both color spaces.
The LG B3 has very good color volume. It displays dark and bright colors well, but its lower peak brightness limits it when it comes to displaying very bright colors. Like all OLEDs, it excels at dark, saturated colors.
The LG B3 has excellent pre-calibration accuracy in SDR. It displays colors well and has minimal inaccuracies to the white balance. However, the color temperature is on the cold side, giving the image a blue tint, and gamma is slightly off from the 2.2 target for moderately-lit rooms, as most scenes are a bit too dark, more so in very dark scenes.
The TV has incredible accuracy after calibration. It's easy to calibrate thanks to its already excellent pre-calibration accuracy. The grayscale was easy to configure, and all white balance issues are gone. The colors are now fantastic, and the TV's gamma and color temperature are now exactly on target.
You can see the full calibration settings used here.
The TV has great gray uniformity. The screen is uniform throughout, and there isn't any noticeable dirty screen effect in the center, which is good for watching sports or using it as a PC monitor. Like any OLED, there are faint vertical lines in near-dark scenes, but they're hard to notice unless you look for them.
Black uniformity on OLEDs is perfect due to their self-emissive pixels; there's no blooming or halo effect around bright objects.
The TV has an outstanding viewing angle. Colors shift slightly when you watch the screen at an angle, but it's minor, and you really won't notice this in practice. You certainly won't have any issues using it in a wide seating area.
The LG B3 has fantastic reflection handling. The intensity of bright lights is significantly reduced, and overall glare isn't an issue for this TV.
The TV has decent gradient handling in HDR. There's some noticeable banding in the entire range of grays and greens, but other color gradients are smooth overall.
The TV has great low-quality content smoothing. There's no noticeable macro-blocking in dark areas, but some fine details are lost in the process.
The LG B3 has good sharpness processing with low-resolution content, but it's not as good as the Sony A75L OLED. Some small details are lost, but the image is upscaled well overall.
These results are with the following processing settings:
The LG B3 uses an RWBG subpixel layout; all four pixels are never on simultaneously. You can see the green pixel here. Note that this TV's subpixel layout causes issues with text display on Windows, as ClearType isn't well adjusted to non-RGB subpixel layouts.
Like all OLED displays, this TV has a nearly instantaneous response time, resulting in incredibly clear motion with minimal ghosting behind fast-moving objects. There's some overshoot in shadow details, but it's minor and not noticeable.
The TV isn't technically flicker-free as there's a slight dip in brightness every 8 ms, which coincides with the 120Hz refresh rate of the display. It's very different from pulse width modulation flicker (PWM) on TVs with LED backlights and isn't noticeable.
The LG B3 OLED has an optional black frame insertion feature (BFI) that reduces the appearance of persistence blur caused by the TV's nearly instantaneous pixel response time. Unfortunately, it can only flicker at 60Hz, which isn't ideal for 120 fps games. BFI also reduces the TV's perceived brightness, which is noticeable in practice.
This LG B3 OLED TV offers an optional motion interpolation feature to improve the appearance of motion. Like most TVs, it struggles with fast-paced content, resulting in noticeable artifacts and loss of detail. These issues are noticeable even with lower settings, but it's not nearly as obvious.
Like all OLEDs, there's noticeable stutter with low frame rate content due to their incredibly fast pixel response time. It's very noticeable in slow panning shots in movies, although some people are more sensitive to it than others. The black frame insertion feature and the motion interpolation feature can help reduce the appearance of stutter, but they both have their drawbacks.
The TV can remove judder when watching 24p movies or TV shows, even from sources that can only send a 60Hz signal, like a cable box. Sadly, movies aren't judder-free when BFI is enabled.
The TV supports FreeSync and HDMI Forum VRR and is G-SYNC Compatible certified, ensuring a nearly tear-free gaming experience from any VRR-enabled source. It works well across a wide refresh rate range, even when it drops very low, as the TV supports Low Framerate Compensation (LFC).
The TV has low input lag, resulting in a very responsive gaming experience. Although it's still not as good as high-end gaming monitors, it's better than most TVs and good enough for most gamers. These results are with the Boost Mode setting set to 'On' in the 'Game Optimizer' menu.
The LG B3 OLED supports most common resolutions up to 4k @ 120Hz on HDMI ports 3 and 4. While there are some text clarity issues due to its subpixel layout (see the Pixels section for more information), it still displays chroma 4:4:4 properly with all supported resolutions. HDMI ports 1 and 2 are limited to HDMI 2.0 bandwidth and don't support certain signals, like 4k @ 120Hz with chroma 4:4:4.
This TV is fully compatible with everything the PS5 supports on HDMI ports 3 and 4, like 1440p @ 120Hz and 4K @ 120Hz, as well as HDMI Forum VRR.
This TV is fully compatible with everything the Xbox Series X|S offers on HDMI ports 3 and 4, including 1440p @ 120Hz, 4k @ 120Hz, Dolby Vision gaming @ 120Hz, HDMI Forum VRR, and FreeSync.
The TV has two HDMI 2.1 bandwidth ports, but one of them also doubles as the eARC/ARC port. That means that when a soundbar is connected to the TV, you only have one HDMI 2.1 bandwidth port left for your high-speed devices. Sadly, the tuner only supports ATSC 1.0, so you can't use it for over-the-air 4k channels.
This TV supports eARC, allowing you to pass high-quality, uncompressed audio to a compatible receiver through an HDMI cable.
The TV has a decent frequency response. It's good enough for the dialogue to sound clear and bright, but you need a dedicated subwoofer to have the best sound experience with proper bass.
The TV's handling of distortion is okay. The TV gets loud, but the speakers struggle to handle distortion when being fed multiple simultaneous frequencies, as seen in their high levels of intermodulation distortion. The TV performs better when dealing with distortion from individual fundamental frequencies (THD).
The TV runs the 2023 version of LG's proprietary smart interface, webOS. The interface is fast and easy to use, and it supports user profiles, so you can customize the home page for different users.
Unfortunately, like almost all smart TVs, there are ads throughout the smart interface, and you can't fully disable them. There are two settings in the 'Home Settings' menu, namely the 'Home Promotion' and 'Content Recommendation' settings, which remove the top banner ads and suggested content from the home screen, but there's no way to remove ads from the apps page.
Like other webOS-equipped TVs, the LG B3 has a great selection of apps, and you're sure to find your favorite content.
The LG Magic Remote has a point-and-press feature that makes it easy to navigate through the menu. The built-in mic allows you to ask it to change inputs, open apps, and search for content. Unlike the LG C3 OLED, there's no mic built into the TV for hands-free control.
The button is underneath the center of the TV, allowing you to turn the TV on/off, change inputs, adjust the volume, and switch channels.
