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.
Our Verdict
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.

Our unit was manufactured in October 2023, and you can see the label here.
Compared To Other TVs
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.
See our recommendations for the best OLED TVs, the best LG TVs, and the best TVs for movies.
The LG C3 OLED and the 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 B4 OLED is better than the LG B3 OLED. The B4 has HDMI 2.1 bandwidth on all four ports, whereas the B3 only as it on two, so the B4 is more versatile if you have multiple high-bandwidth devices. The B4 also gets brighter overall, so highlights stand out more in HDR content, and it can overcome more glare in a bright room while watching SDR content. On top of that, the B4 has better HDR gradient handling for less banding.
The LG C4 OLED is better than the LG B3 OLED. While they're very similar with nearly identical features, the C4 has the edge in almost every facet. It is visibly brighter in HDR and SDR, so all content pops noticeably more on the C4 than on the B3. Furthermore, the C4 is the better TV for those who own multiple HDMI 2.1 devices, as it has four full HDMI 2.1 ports with up to 4k @ 144Hz support, while the B3 is limited to two 4k @ 120Hz HDMI 2.1 ports. The B3's HDMI 2.1 ports are back-facing, meaning they're almost impossible to use when the TV is mounted flush against a wall. Finally, one of these ports is also the TV's eARC port, so you lose one of your high bandwidth ports if you have a soundbar connected to the TV.
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 LG B3 OLED and the Sony X90L/X90CL are better than each other in different ways. If you typically watch content in a dark room and want inky blacks, the LG is better due to its nearly infinite contrast ratio and perfect black uniformity. The LG is also the better option for watching TV as a group due to its much wider viewing angle, and its faster response time means there is less blur behind quick motion. However, the Sony is much brighter, so it's better suited for a bright room.
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 (120Hz on the 83-inch model), 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 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 a bit better than the LG C1 OLED. They're very similar and about equally bright in HDR and SDR. However, the B3 has a few upgrades over the older C1, such as better image processing and advanced DTS audio passthrough, making it the more versatile of the two products. The C1 has four full 4k @ 120Hz HDMI ports, while the B3 is limited to two 4k @ 120Hz ports, so if you have a ton of HDMI 2.1 devices, the C1 is more accommodating. Otherwise, the B3 is a slight upgrade over its older cousin.
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 B3 OLED and Hisense U8/U8K excel in different ways. The LG is an OLED, so it looks amazing in dark rooms due to its nearly perfect contrast. Inversely, the Hisense's LED panel is far brighter than the LG's, so it looks superior in rooms with bright lights or windows. The LG is a bit better for a wide seating arrangement due to its wider viewing angle, and it's also a bit better for gamers due to its nearly instantaneous response time, although the Hisense does have two 4k @ 144Hz ports, while the LG has two 4k @ 120Hz ports. Ultimately, the choice between the two might come down to whether you mostly watch content in bright rooms or dark rooms.
The LG G4 OLED is a lot better than the LG B3 OLED. The G4 has HDMI 2.1 bandwidth on all four of its ports, it supports up to 4k @ 144Hz, so it's more versatile if you own multiple devices that need high bandwidth, and it's better for PC gamers with high-end graphics cards. The G4 gets a lot brighter overall, so highlights in HDR content really stand out on it, and it overcomes more glare in a bright room while watching SDR content. You also don't have to trade in brightness for performance on the G4 since it maintains its HDR brightness much better while in Game Mode.
The Samsung S95C OLED is better than the LG B3 OLED. The Samsung gets brighter in SDR, so it can overcome more glare in a bright room, and it gets brighter in HDR, so highlights stand out more in HDR content. Colors look more vibrant and lifelike on the Samsung due to its wider color gamut and better color volume, and there is less banding. Finally, the Samsung is a bit better for PC gamers thanks to its 4k @ 144Hz support.
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 Samsung S89C OLED and LG B3 OLED are both amazing TVs, and while the LG has a few features that the Samsung doesn't have, the S89C 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 LG B3 OLED and the Sharp AQUOS FS1 OLED are similar TVs, but the LG is better. The LG has a wider viewing angle, so the image stays more consistent from the sides than on the Sharp. The LG also has much better overall image processing and a useful BFI feature. On top of that, the LG is brighter in both SDR and HDR.

Test Results
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:
- HDR Picture Mode: Cinema
- OLED Pixel Brightness: 100
- Adjust Contrast: 100
- Peak Brightness: High
- Color Temperature: Warm 50
- Dynamic Tone Mapping: Off
- Auto Dynamic Contrast: Off
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:
- Picture Mode: Game Optimizer
- OLED Pixel Brightness: 100
- Adjust Contrast: 100
- Dynamic Tone Mapping: HGiG
- Peak Brightness: High
- Color Temperature: Warm 50
Here are measurements with Dynamic Tone Mapping set to 'On':
Here are measurements with Dynamic Tone Mapping set to 'Off':
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:
- Picture Mode: Expert (Dark Space, Night)
- OLED Pixel Brightness: 100
- Adjust Contrast: 85
- Peak Brightness: High
- Color Temperature: Warm 50
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:
- Peak 2% Window: 268 cd/m²
- Peak 10% Window: 269 cd/m²
- Peak 25% Window: 270 cd/m²
- Peak 50% Window: 268 cd/m²
- Peak 100% Window: 160 cd/m²
- Sustained 2% Window: 259 cd/m²
- Sustained 10% Window: 258 cd/m²
- Sustained 25% Window: 258 cd/m²
- Sustained 50% Window: 256 cd/m²
- Sustained 100% Window: 155 cd/m²
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:
- Adjust Sharpness: 16
- Super Resolution: High
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.
