Because OLEDs can turn off individual pixels, the TV has incredible black uniformity with no blooming or halo effect around bright objects.

Since OLEDs don't use lighting zones and instead have individual pixels that can be lit up to their maximum brightness next to pixels that are turned off, there's no blooming when bright elements are surrounded by deep blacks.

The LG B4 OLED supports the full 48Gbps bandwidth of HDMI 2.1 on all four HDMI ports. This allows you to take full advantage of multiple high-bandwidth devices, like if you own both current-gen consoles and a high-end gaming PC.

The TV has good HDR color volume. It displays dark, saturated colors very well, and its ability to display bright whites is excellent. It doesn't display other colors nearly as brightly as it does whites, but it's still enough to display impactful colors.

The LG B4 Series uses a WOLED panel with a RWBG pixel structure where all four pixels are never lit at the same time. Due to its subpixel layout, it has minor issues with displaying text on Windows since ClearType isn't well optimized for non-RGB subpixel layouts, but most users won't be bothered by this.The white subpixel does an excellent job helping the TV display bright whites, but it dilutes the color purity of greens and reds.

The LG B4 has decent HDR brightness. In combination with its remarkable contrast, it gets bright enough for highlights to stand out, but it's not bright enough to properly display very bright highlights. Unfortunately, large bright scenes are significantly dimmer than smaller, specular highlights due to its aggressive Automatic Brightness Limiter (ABL).

7''TFT Display

The TV supports FreeSync and HDMI Forum VRR and is certified as G-SYNC compatible, ensuring a nearly tear-free gaming experience from any VRR-enabled source.

The TV has great gray uniformity. There are some very faint vertical lines on the panel, but these aren't noticeable from a normal viewing distance.

There's no difference in dark scene behavior between the calibrated picture modes and when the TV is set in Game Optimizer.

The LG B4 OLED and the LG C3 OLED are very similar overall. The C3 has better low-quality content smoothing, and its viewing angle is a bit better, with less color shift as you move off-center. The C3 also gets brighter overall, so it overcomes a bit more glare while watching SDR content in a bright room, and highlights stand out a bit more in HDR content. However, the C3 is noticeably dimmer while using the Game Optimizer, whereas the B4 maintains its brightness in that mode, which makes it a bit brighter overall while using Game Optimizer.

We tested the 65-inch LG B4 (OLED65B4PUA), and the results are also valid for the 55-inch and 77-inch models. The 48" model performs mostly the same but isn't quite as bright as the larger models. 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. The variant that carries the suffix 'AUA' supports Wi-Fi 6E (the PUA variant has Wi-Fi 5).

The TV is fully compatible with everything the PS5 offers, like 1440p @ 120Hz and 4k @ 120Hz, as well as HDMI Forum VRR. It also supports Auto Low Latency Mode, so you don't have to worry about switching to Game Optimizer to get the lowest input lag.

The LG B4 OLED supports the full 48Gbps bandwidth of HDMI 2.1 on all four HDMI ports. This allows you to take full advantage of multiple high-bandwidth devices, like if you own both current-gen consoles and a high-end gaming PC.

The only difference I see see is that the Adafruit implementation supports the SPI interface only. The Buydisplay version of the RA8875 supports both parallel and SPI versions. That's a decision you need to make at some point - but you'd need to test both in order to know which one is faster. Ultimately, I don't know if speed versus I/O count matters to you.

Outside of the two feet instead of a central stand, the B4 has a very similar look to 2023's LG B3 OLED. It's a thin TV with a silver frame and thin black bezels. It looks elegant and modern overall.

Unfortunately, the TV has a bug that sometimes causes it to not properly switch out of the Game Optimizer setting, so you're locked out of settings that should be available in other picture modes. To fix this, you can turn the TV off/on or change the input label a few times. When you do this and switch to a different picture setting, everything works as it should.

The TV removes judder when watching 24p movies or TV shows when the Real Cinema setting is enabled, even from sources that can only send a 60Hz signal, like a cable box. Unfortunately, movies and TV shows aren't judder-free when BFI is enabled because the BFI feature only flickers at 60Hz.

Since OLEDs don't use lighting zones and instead have individual pixels that can be lit up to their maximum brightness next to pixels that are turned off, there's no blooming when bright elements are surrounded by deep blacks.

The LG B4 has outstanding accuracy in HDR before calibration. Its white balance is fantastic, but there's not enough blue in some lighter grays, which makes its color temperature slightly cooler than 6500K. The TV's color accuracy is excellent, but there are some mapping errors throughout, most notably in warmer colors.

The TV has great total reflection handling. Its glossy screen finish significantly reduces the intensity of indirect reflections, and there's no light banding or other distracting artifacts.

The LG B4 OLED and the LG C2 OLED are very similar overall, but the B4 is a bit better. Thanks to its superior HDR brightness, the B4 displays brighter highlights in HDR content, and it's more accurate in SDR and HDR. The B4 has slightly less banding in color gradients, does a better job upscaling low-resolution content, and supports DTS passthrough for those who collect physical media. On the other hand, the C2 does a better job cleaning artifacts in low bitrate content.

The LG B4 OLED has exceptional black levels in a bright room. Black levels are barely raised in a room with ambient lighting, and they remain deep and punchy.

The TV has an optional motion interpolation feature to help improve the appearance of motion. It works well with slower scenes but struggles with fast-moving action, so there's noticeable haloing and artifacts present in busier scenes, especially if you use the settings too aggressively.

The LG B4 OLED is LG's entry-level TV in their 2024 OLED lineup. It sits below the LG C4 OLED and uses LG's α8 AI Processor 4K, which is designed to provide better image processing and can automatically optimize the TV's picture and sound settings. Only two of the four HDMI ports on 2023's LG B3 OLED had HDMI 2.1 bandwidth, but this 2024 model has HDMI 2.1 bandwidth on all four HDMI ports. The TV adds 'Filmmaker Mode' as a picture setting for Dolby Vision, designed to preserve the content creator's intent without needing to change any settings. The TV uses the 2024 version of LG's webOS, and it has a 20W 2.0 channel speaker built-in that can be virtually up-mixed to 9.1.2 using the α8 AI Sound Pro feature. LG is releasing the B4 in a new, smaller 48-inch model, which in the past was only available in their C-Series lineup and their discontinued A-Series lineup. It's available in five sizes: 48-inch, 55-inch, 65-inch, 77-inch, and 83-inch.

The TV has an excellent viewing angle. Unfortunately, there's a noticeable green tint when you look at the screen from an angle, and the green tint worsens the more you move off-center, although it's not as noticeable as it is on the LG C4 OLED.

The TV is fully compatible with everything the Xbox Series X|S offers, including 1440p @ 120Hz, 4k @ 120Hz, HDMI Forum VRR, FreeSync Premium Pro, and Dolby Vision gaming. It also supports Auto Low Latency Mode, so you don't have to worry about switching to Game Optimizer to get the lowest input lag.Unfortunately, with firmware 23.20.20 and 23.20.24, there's a handshaking issue with Dolby Vision and VRR enabled at the same time, and the screen will constantly go black for a brief moment every few seconds. You have to disable one or the other for the TV to work properly. This wasn't an issue on the older 03.10.37 firmware.

It also supports Auto Low Latency Mode, so you don't have to worry about switching to Game Optimizer to get the lowest input lag.

The LG B4 OLED has very low input lag when set to Game Optimizer with 'Prevent Input Delay' set to 'Boost,' resulting in a responsive gaming experience. For chroma 4:4:4 to work properly, you must set the input label to 'PC,' or the '4:4:4 Passthrough' setting must be enabled.

The LG C4 OLED is better than the LG B4 OLED for the most part. The C4 has better reflection handling and slightly better SDR peak brightness, so it handles a bit more glare in a bright room, and it has better low-quality content smoothing. The C4 also gets brighter in HDR in most picture modes, making highlights pop more in HDR content. However, the two TVs have very similar HDR brightness while using the Game Optimizer picture mode.

The TV supports many audio formats, including DTS audio formats, which is great if you like to watch DVDs or Blu-rays, as they often use DTS for their main audio tracks.

The LG B4 has mediocre direct reflection handling. It doesn't do the best job reducing the intensity of direct reflections, so glare from lamps or windows opposite the screen is distracting.

The LG B4 has decent HDR brightness. In combination with its remarkable contrast, it gets bright enough for highlights to stand out, but it's not bright enough to properly display very bright highlights. Unfortunately, large bright scenes are significantly dimmer than smaller, specular highlights due to its aggressive Automatic Brightness Limiter (ABL).These measurements are after calibrating the HDR white point with the following settings:HDR Picture Mode: CinemaOLED Pixel Brightness: 100Contrast: 100Auto Dynamic Contrast: OffDynamic Tone Mapping: OffPeak Brightness: HighColor Temperature: Warm 50

The LG B4 is great for a home theater. It's an OLED, so you get those perfect black levels with no blooming. The TV's HDR brightness is decent enough that highlights stand out against darker backgrounds, and it displays vibrant and lifelike colors with minimal banding, so HDR content is impactful. Furthermore, it respects the intent of the content creator when it comes to the brightness of HDR content, so you don't get an over or under brightened image. The TV has great upscaling capabilities, and it does well cleaning up artifacts in heavily compressed media, which is great when the quality of your content isn't ideal. Unfortunately, due to the TV's nearly instantaneous response time, there's noticeable stutter in movies and TV shows.

The LG B4 OLED is an excellent entry-level OLED and has noticeable improvements over the LG B3 OLED. The biggest difference is its increased brightness in both SDR and HDR, which makes it more suitable for a brighter room, and it delivers a more impactful HDR experience than its predecessor. The B4 doesn't really have any direct competitors, since most OLEDs from brands like Sony, Panasonic, and Samsung are more in line with the LG C4 OLED price-wise. This makes it an excellent choice for those on a budget who need a solid TV for their home theater. It's also great for gamers looking to get their first OLED TV, especially since it has HDMI 2.1 bandwidth on all four of its ports and is available in a 48-inch model.

The LG B4 OLED is better than the Samsung S85D OLED. The LG is brighter in HDR, and it maintains its brightness much better while using Game Mode, leading to a more impactful HDR experience. The LG is also significantly more accurate in HDR and SDR. Additionally, the LG has the edge with low-quality content smoothing, and it supports Dolby Vision and DTS audio formats.

Unlike the LG B3 OLED, all sizes of the B4 use two wide-set metal feet instead of a stand. The feet hold the TV very well, and there is minimal wobble when the TV is pushed on. The feet lift the TV about 3.2 inches above the table, so pretty much any soundbar will fit underneath without blocking the screen. The TV comes with two plastic clips that can be attached to the feet for cable management.

The LG B4 delivers sharp motion at its maximum refresh rate of 120Hz. There's a bit of overshoot when some shades transition from a dark state to near black, but these transitions settle quickly, so you don't notice it.

Okay thanks for the advice about using a due. Then how can I connect the Controller Board Serial I2C to the Due? Do I need a shield or can it be achievable in some other way ?

The TV has remarkable contrast and a nearly infinite contrast ratio. Due to OLED's self-lit pixels, the TV displays bright highlights next to perfect inky blacks, making it very impressive in a dark room.

We retested the TV's Xbox Series X|S Compatibility using firmware 23.20.20 and 23.20.24 and confirmed that there are issues using a combination of Dolby Vision and VRR.

The TV has good low-quality content smoothing. It does a very good job of preserving details while doing a good job at removing artifacts, but there is still some noticeable macro-blocking in dark scenes. Setting 'Smooth Gradation' to 'High' behaves differently than the LG B3 OLED and doesn't actually smooth out many artifacts at all. The picture you see is with 'Smooth Gradation' set to 'Medium.'You can see the results with the other settings below.Smooth Gradation: OffSmooth Gradation: LowSmooth Gradation: High

There's no noticeable difference with HDR brightness when the TV is set into Game Optimizer.These measurements are after calibrating the HDR white point with the following settings: HDR Picture Mode: Game Optimizer OLED Pixel Brightness: 100 Contrast: 100 Dynamic Tone Mapping: HGiG Peak Brightness: High Color Temperature: Warm 50

The graphics drivers are on the LCD board, common types are the SSD1963 and RA8875. Buydisplay sells both driver types with the standard 20x2 connector and shields as well. It's probably worth a mention that there are far more driver choices in smaller displays but when you get to the higher pixel counts, the field narrows rapidly.

The LG B4 OLED and the LG C2 OLED are very similar overall, but the B4 is a bit better. Thanks to its superior HDR brightness, the B4 displays brighter highlights in HDR content, and it's more accurate in SDR and HDR. The B4 has slightly less banding in color gradients, does a better job upscaling low-resolution content, and supports DTS passthrough for those who collect physical media. On the other hand, the C2 does a better job cleaning artifacts in low bitrate content.

Note: We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.The LG B4 has great image processing overall. The brightness of HDR content is very accurate, so it stays true to the content creator's intent, and color gradients are smooth with minimal banding. It does a very good job upscaling low-resolution content so it doesn't look too soft. The TV's low-quality content smoothing reduces the amount of artifacts you see in low bitrate content, but it doesn't eliminate them completely.

The LG B4 OLED is better than the Sony X90L/X90CL. The Sony's contrast is excellent, but the LG's OLED panel gives it perfect blacks, easily giving it the edge over the Sony. When it comes to brightness, the Sony is the slightly brighter product of the two, especially in SDR, giving it the edge in brighter rooms even though the LG has better reflection handling. If you like to host large viewing parties, it's hard to beat an OLED like the LG B4, as its viewing angle is vastly wider than the Sony's; the image stays mostly uniform even when watched from extreme angles. The LG is also the better choice if you're a gamer due to its nearly instantaneous response time and lower input lag than the Sony. The Sony does have better image processing overall, but it doesn't offset the LG's image quality advantage.

The TV has good HDR color volume. It displays dark, saturated colors very well, and its ability to display bright whites is excellent. It doesn't display other colors nearly as brightly as it does whites, but it's still enough to display impactful colors.

VFDs (Vacuum Fluorescent Display) produce bright characters and icons with a sharp contrast that exceeds older twisted nematic technology.

The TV does a very good job at upscaling low-resolution content like DVDs or lower-resolution streams. Details are clear enough, but very fine details are hard to make out.

The TV has an excellent viewing angle. Unfortunately, there's a noticeable green tint when you look at the screen from an angle, and the green tint worsens the more you move off-center, although it's not as noticeable as it is on the LG C4 OLED.

I2C is okay for a character based LCD but it is waaayyy too slow to drive a TFT, it's by far the worst choice, even with the 400khz high speed version. SPI is a reasonable choice if I/O pins are in short supply, SPI with DMA is even better.

The TV has incredible accuracy in HDR after calibration. Its white balance is a bit better now, but there's still a bit too much blue in mid grays, so the TV's color temperature is just a touch too cool. However, most people won't notice these very minor inaccuracies. Colors as a whole are slightly more accurate than before, but there's still some very minor mapping errors, and reds are a bit undersaturated.

The LG B4 OLED TV has a decent frequency response. The TV speakers don't produce much bass, but the sound profile is well-balanced enough that the dialogue is clear. The speakers can get pretty loud, but there are compression and pumping artifacts at maximum volume.

The LG B4 supports all common formats, but it doesn't support 144Hz like the LG C4 OLED and the LG G4 OLED do. It displays chroma 4:4:4 properly, which is important for clear text from a PC.There are two settings you can use to passthrough proper chroma 4:4:4. The first is to change the input label to 'PC.' The second is to enable the '4:4:4 Passthrough' setting in the 'HDMI Settings' menu. Both of these options work the same and lock you out from using the 'Peak Brightness,' 'Noise Reduction,' 'MPEG Noise Reduction,' 'Smooth Gradation,' and 'Real Cinema' settings.

The LG B4 OLED and the Panasonic Z85A OLED are evenly matched, but there are some minor differences. The LG is brighter in SDR, so it handles more glare in a room with the lights on. The LG also has a bit less banding in color gradients and does a slightly better job cleaning up artifacts in low bitrate content. However, the Panasonic has slightly better upscaling capabilities.

We wrote text for the new tests and rewrote text throughout the review after updating pre-existing tests and scores for Test Bench 2.0.

The Samsung S85F (QD-OLED version) has better color performance than the LG B4 OLED. On the other hand, the LG is a bit brighter overall, has the edge when it comes to image processing, and it supports Dolby Vision and DTS audio formats. The LG also maintains its black levels much better than the Samsung in a bright room. Inversely, the Samsung does a better job reducing the intensity of direct reflections.

The 83-inch model shares a lot of similarities with the LG C4 OLED. It uses LG's Alpha 9 AI Processor Gen7, supports a 144Hz refresh rate, has three USB ports, and has a 2.2 channel speaker system, all of which are the same as the C4. Due to these shared features, we expect the 83-inch model to perform more in line with the C4. However, it doesn't have LG's Brightness Booster technology like the C4 does, so it isn't as bright overall.

The LG B4 is very good for mixed usage. Unfortunately, the TV isn't bright enough and doesn't have the reflection handling needed for a bright room, so it's best suited for a moderately lit environment. However, it's well-suited for use in reference conditions like a home theater since it has vibrant colors, perfect blacks, and incredible accuracy. It lacks some brightness in HDR to fully display highlights in some very bright content, but most HDR content looks excellent. The TV is also a solid option for gaming, thanks to its modern gaming features and sharp motion. Finally, it's a solid option for watching content with a group of friends due to its wide viewing angle.

The LG B4 has outstanding pre-calibration SDR accuracy. There is a bit of too much blue and red in some shades of gray, but it's so minor that even the most keen-eyed observers won't notice it. Color temperature is incredibly close to our target of 6500K, and colors are so accurate that color enthusiasts will be pleased. Gamma is a bit off of our 2.2 target, though, with bright and dark scenes being displayed too brightly.

The LG B4 Series uses a WOLED panel with a RWBG pixel structure where all four pixels are never lit at the same time. Due to its subpixel layout, it has minor issues with displaying text on Windows since ClearType isn't well optimized for non-RGB subpixel layouts, but most users won't be bothered by this.

The TV does a very good job at upscaling low-resolution content like DVDs or lower-resolution streams. Details are clear enough, but very fine details are hard to make out.Sharpness processing was calibrated with no over-sharpening for low-resolution content, with the following settings:Sharpness: 16Super Resolution: High

The LG B4 doesn't have a traditional backlight and doesn't use pulse-width modulation (PWM) to dim each pixel, but it's not completely flicker-free. There's a slight dip in brightness that corresponds to the TV's refresh rate. This differs from the PWM flicker on TVs with LED backlights and occurs on every OLED we've tested. It's not noticeable, and most people won't be bothered by this, but it can still bother people who are extra sensitive to flicker.

The Samsung S90C OLED is better than the LG B4 OLED. The S90C gets brighter in HDR, so highlights pop more on it. The S90C also displays more vibrant, lifelike, and bright colors overall due to its wider color gamut and better color volume, and its better viewing angle means that there is very little color shift when watching the TV from an angle. However, the B4 has better image processing, so low-resolution and low-quality content looks better on it, and it supports Dolby Vision and DTS audio formats.

The LG B4 OLED is far better than the TCL QM6K. The TCL's one advantage is that it is brighter in SDR, but the LG compensates with its far superior reflections handling, meaning it still looks better in brighter rooms when watching SDR content. The TCL is also capable of gaming at 144Hz and even 288Hz, far higher than the LG's 120Hz, but it can't quite match the OLED's nearly instantaneous pixel transitions. Overall, the LG is in a different league.

The LG B4 is great for gaming. Its HDR brightness is only decent, so highlights aren't super bright in HDR games, but those games are still impactful thanks to the TV's perfect black levels and vibrant colors. The TV has HDMI 2.1 bandwidth on all four ports for up to 4k @ 120Hz, and it supports all three popular versions of VRR to reduce screen-tearing, which makes it fully compatible with modern consoles. It also has low input lag and nearly instantaneous pixel transitions, so gaming feels very responsive.

Note: We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.

The LG G4 OLED is better than the LG B4 OLED, mostly due to its brightness capabilities. The G4 overcomes more glare in a bright room thanks to its superior SDR brightness and reflection handling, and its higher HDR peak brightness means highlights pop out more in HDR movies, shows, and games. Colors are also brighter on the G4 thanks to its better color volume. The G4 has better overall image processing. It does a better job upscaling low-resolution content, cleans up more artifacts in low bitrate content, and has less banding in color gradients. Finally, the G4 is slightly better for PC gamers thanks to its 144Hz support.

The LG B4 OLED provides better picture quality than the LG QNED90T. The B4 has better color accuracy and PQ EOTF tracking, so it's the more accurate TV overall. The B4 also has a quicker response time for less blur behind fast motion and lower input lag, so it's the better TV for gaming. Additionally, the B4 has better contrast that provides inky blacks, and its wide viewing angle makes it more suitable for use in a group setting.

The Samsung S90D OLED is better than the LG B4 OLED. They both look amazing in dark rooms due to their nearly perfect contrast, but the Samsung is noticeably brighter in HDR. The Samsung also has a much wider color gamut, giving it a more impactful HDR viewing experience. Regarding image processing, the Samsung model has much less banding in its HDR color gradients. Still, the LG has slightly better low-quality content smoothing, so streaming content looks a bit cleaner overall. The LG model supports Dolby Vision, while the Samsung instead supports the less widely used HDR10+ format. Finally, the Samsung is superior for PC gamers due to its four 4k @ 144Hz HDMI ports, while the LG is limited to 120Hz on its four ports.

The TV has great total reflection handling. Its glossy screen finish significantly reduces the intensity of indirect reflections, and there's no light banding or other distracting artifacts.

The LG B4 OLED is better than the Samsung S85D OLED. The LG is brighter in HDR, and it maintains its brightness much better while using Game Mode, leading to a more impactful HDR experience. The LG is also significantly more accurate in HDR and SDR. Additionally, the LG has the edge with low-quality content smoothing, and it supports Dolby Vision and DTS audio formats.

Parallel I/O, 16 bits wide, is usually the fastest way to drive a screen but the Due presents a conundrum in that regard as the designers mapped the physical ports to the digital pins rather poorly, the result being you have to bit twiddle and write to multiple hardware ports to achieve parallel I/O, thereby decreasing the overall efficiency. This is really not a concern if you're using an exsisting library, only if you're writing your own code but I mention this as you said you would be making your own board - and so you could address this deficiency.

The LG B4 OLED has exceptional black levels in a bright room. Black levels are barely raised in a room with ambient lighting, and they remain deep and punchy.

The LG B4 is an OLED and has no backlight, so its self-lit pixels give it the same performance as a TV with perfect local dimming and no zone transitions. We still film the zone transition video on the TV so you can see how it compares to a TV with local dimming.

The LG B4 OLED and the Panasonic Z85A OLED are evenly matched, but there are some minor differences. The LG is brighter in SDR, so it handles more glare in a room with the lights on. The LG also has a bit less banding in color gradients and does a slightly better job cleaning up artifacts in low bitrate content. However, the Panasonic has slightly better upscaling capabilities.

Unfortunately, with firmware 23.20.20 and 23.20.24, there's a handshaking issue with Dolby Vision and VRR enabled at the same time, and the screen will constantly go black for a brief moment every few seconds. You have to disable one or the other for the TV to work properly. This wasn't an issue on the older 03.10.37 firmware.

The TV has great gray uniformity. There are some very faint vertical lines on the panel, but these aren't noticeable from a normal viewing distance.

The LG B4 has okay SDR brightness. It gets bright enough to handle glare in a bright room, although it's better suited for a moderately lit room. Fortunately, the TV's Automatic Brightness Limiter isn't aggressive in SDR, so you don't have to deal with the screen dimming considerably when large areas of brightness are present.These measurements are after calibration with the following settings:Picture Mode: Dark Space, nightOLED Pixel Light: 100Peak Brightness: HighColor Temperature: Warm 50

The Samsung S90D OLED is better than the LG B4 OLED. They both look amazing in dark rooms due to their nearly perfect contrast, but the Samsung is noticeably brighter in HDR.

Finally, the Samsung is superior for PC gamers due to its four 4k @ 144Hz HDMI ports, while the LG is limited to 120Hz on its four ports.

The TV runs the 2024 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. LG promises at least four years of webOS updates on their TVs, and the B4 is expected to receive webOS 25 towards the end of 2025.Unfortunately, the TV has a bug that sometimes causes it to not properly switch out of the Game Optimizer setting, so you're locked out of settings that should be available in other picture modes. To fix this, you can turn the TV off/on or change the input label a few times. When you do this and switch to a different picture setting, everything works as it should.Another bug causes the TV to flash on and off aggressively after enabling Game Optimizer. This lasts for a few seconds before the connection stabilizes.

The LG B4 has outstanding responsiveness while using the Game Optimizer. The TV's input lag is very low across the board, and it supports VRR for a nearly tear-free experience, so gaming feels responsive. It also has nearly instantaneous pixel transitions, which makes fast motion very clear.

The LG B4 has okay SDR brightness. It gets bright enough to handle glare in a bright room, although it's better suited for a moderately lit room. Fortunately, the TV's Automatic Brightness Limiter isn't aggressive in SDR, so you don't have to deal with the screen dimming considerably when large areas of brightness are present.

The LG C4 OLED is better than the LG B4 OLED for the most part. The C4 has better reflection handling and slightly better SDR peak brightness, so it handles a bit more glare in a bright room, and it has better low-quality content smoothing. The C4 also gets brighter in HDR in most picture modes, making highlights pop more in HDR content. However, the two TVs have very similar HDR brightness while using the Game Optimizer picture mode.

A display shield is the fastest and easiest way to get a TFT LCD up and running on an Arduino. There is an undefined "standard" for this, ultilizing a 20x2 header pin connection to the LCD, a typical example:

The LG B4 is decent for watching sports. Unfortunately, the TV isn't very bright in SDR and struggles with direct reflections, so it's not the best option for watching the game on a sunny afternoon with the curtains open. However, there's barely any dirty screen effect in the center of the screen thanks to its very good uniformity, and motion is smooth due to its fast response time. It does a very good job upscaling SD and HD broadcasts and streams, and it does well smoothing out artifacts when watching games with a lot of compression. You also get vibrant and accurate colors, so your favorite teams' jersey looks the way it should. Its wide viewing angle means the image doesn't degrade when viewed from the sides of the screen, which is great for watching the game with a group of friends.

The TV has good perceived color volume in ambient lighting. Colors shown at all levels of luminance are still vibrant and saturated in a bright room since they only lose a small amount of saturation from ambient sources of light.

The LG B4 OLED is generally better than the Hisense U8/U8N, but they excel in different ways. The LG is an OLED, so it has perfect blacks, making it truly stand out when watched in dark rooms. The Hisense also has exceptional contrast, but it still can't quite match an OLED. Still, the Hisense is far brighter in HDR and SDR, easily making it more visually impressive when watched in brighter rooms. The LG has the edge if you care about accuracy, as it's more accurate in SDR and HDR. It also has a much wider viewing angle than the Hisense. Finally, the LG OLED is better for gamers due to its nearly instantaneous response time; although the Hisense offers 4k @ 144Hz on two ports, the LG is limited to 120Hz on its four ports.

Since the LG B4 is an OLED, it has perfect black levels. Blacks are deep and inky when viewed in a dark room, with no blooming around bright highlights.

The TV's CAD at 60Hz is fantastic. Most transitions from one RGB level to another are nearly instantaneous, but it's slightly slower when transitioning from blacks. There's also still some noticeable persistence blur due to the nature of a 60Hz refresh rate.

The TV has incredible accuracy in HDR after calibration. Its white balance is a bit better now, but there's still a bit too much blue in mid grays, so the TV's color temperature is just a touch too cool. However, most people won't notice these very minor inaccuracies. Colors as a whole are slightly more accurate than before, but there's still some very minor mapping errors, and reds are a bit undersaturated.

The LG B4 OLED is better than the Sony X90L/X90CL. The Sony's contrast is excellent, but the LG's OLED panel gives it perfect blacks, easily giving it the edge over the Sony. When it comes to brightness, the Sony is the slightly brighter product of the two, especially in SDR, giving it the edge in brighter rooms even though the LG has better reflection handling. If you like to host large viewing parties, it's hard to beat an OLED like the LG B4, as its viewing angle is vastly wider than the Sony's; the image stays mostly uniform even when watched from extreme angles. The LG is also the better choice if you're a gamer due to its nearly instantaneous response time and lower input lag than the Sony. The Sony does have better image processing overall, but it doesn't offset the LG's image quality advantage.

After calibration, the TV is even more accurate. White balance, gamma, and color temperature are close to perfect, and colors are even slightly more accurate than they were before.See our full calibration settings.

Outside of the two feet instead of a central stand, the B4 has a very similar look to 2023's LG B3 OLED. It's a thin TV with a silver frame and thin black bezels. It looks elegant and modern overall.

The TV has an optional black frame insertion (BFI) feature that reduces the appearance of persistence blur caused by the TV's nearly instantaneous response time. It can only insert black frames at a 60Hz refresh rate.

The LG B4 has exceptional PQ EOTF tracking. It follows the curve almost perfectly until it approaches the TV's maximum brightness. With content mastered at 600 or 1000 nits, there is a gradual roll-off near the TV's peak brightness to maintain some detail in bright highlights. With content mastered at 4000 nits, the roll-off happens much sooner to preserve detail in very bright highlights.

The TV has very good HDR native gradient handling. There's some noticeable banding in dark grays and dark greens, but all other colors have minimal banding or no banding at all.

The LG B4 OLED has the same Magic Remote as the LG B3 OLED. You can use the remote as a pointer or use the traditional buttons to control the TV. The TV also supports hands-free voice control through microphones on the unit itself. You can use your voice to change inputs, open apps, search for content, and ask for the weather and time.

The TV delivers sharp motion at its maximum refresh rate of 120Hz. There's a bit of overshoot when some shades transition from a dark state to near black, but these transitions settle quickly, so you don't notice it.

The LG B4 has very good SDR color volume. Its coverage of the DCI-P3 color space is outstanding, and it covers the majority of that space, only struggling a bit with some very light colors.

The LG G4 OLED is better than the LG B4 OLED, mostly due to its brightness capabilities. The G4 overcomes more glare in a bright room thanks to its superior SDR brightness and reflection handling, and its higher HDR peak brightness means highlights pop out more in HDR movies, shows, and games. Colors are also brighter on the G4 thanks to its better color volume. The G4 has better overall image processing. It does a better job upscaling low-resolution content, cleans up more artifacts in low bitrate content, and has less banding in color gradients. Finally, the G4 is slightly better for PC gamers thanks to its 144Hz support.

The LG B4 has outstanding accuracy in HDR before calibration. Its white balance is fantastic, but there's not enough blue in some lighter grays, which makes its color temperature slightly cooler than 6500K. The TV's color accuracy is excellent, but there are some mapping errors throughout, most notably in warmer colors.

The LG B4 is adequate for a bright room. The TV struggles to reduce the intensity of direct reflections, so it's not a good choice if you have wall lights, lamps, or a window opposite the screen. However, blacks remain deep, and colors remain well-saturated in ambient lighting, so you don't lose a ton of picture quality when you have your lights on. Unfortunately, the TV is only bright enough to fight glare in moderately lit rooms.

Another bug causes the TV to flash on and off aggressively after enabling Game Optimizer. This lasts for a few seconds before the connection stabilizes.

You should be able to do that. That said, you can also buy the 800x480 LCD directly from Adafruit and you'd have their support to get things running. While it's certainly more money, it's light years faster delivery and you'd have a real warranty versus a warranty that would require you to return the LCD to China for replacement. Just my 0.02 cents.

The LG B4 OLED has very low input lag when set to Game Optimizer with 'Prevent Input Delay' set to 'Boost,' resulting in a responsive gaming experience. For chroma 4:4:4 to work properly, you must set the input label to 'PC,' or the '4:4:4 Passthrough' setting must be enabled.

The LG B4 OLED has the same Magic Remote as the LG B3 OLED. You can use the remote as a pointer or use the traditional buttons to control the TV.

The LG B4 has impressive colors. It has solid color volume overall, so colors are vibrant and lifelike, but it does struggle more with displaying very light colors. Fortunately, this is an incredibly accurate TV in both SDR and HDR that respects the content creator's intent without needing calibration.

The LG B4 has great image processing overall. The brightness of HDR content is very accurate, so it stays true to the content creator's intent, and color gradients are smooth with minimal banding. It does a very good job upscaling low-resolution content so it doesn't look too soft. The TV's low-quality content smoothing reduces the amount of artifacts you see in low bitrate content, but it doesn't eliminate them completely.

We tested the 65-inch LG B4 (OLED65B4PUA), and the results are also valid for the 55-inch and 77-inch models. The 48" model performs mostly the same but isn't quite as bright as the larger models. 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. The variant that carries the suffix 'AUA' supports Wi-Fi 6E (the PUA variant has Wi-Fi 5).The 83-inch model shares a lot of similarities with the LG C4 OLED. It uses LG's Alpha 9 AI Processor Gen7, supports a 144Hz refresh rate, has three USB ports, and has a 2.2 channel speaker system, all of which are the same as the C4. Due to these shared features, we expect the 83-inch model to perform more in line with the C4. However, it doesn't have LG's Brightness Booster technology like the C4 does, so it isn't as bright overall.SizeUS Model (Wi-Fi 5)Variant (Wi-Fi 6E)48"OLED48B4PUAOLED48B4AUA55"OLED55B4PUAOLED55B4AUA65"OLED65B4PUAOLED65B4AUA77"OLED77B4PUAOLED77B4AUA83"OLED83B4PUAOLED83B4AUAOur unit was manufactured in March 2024.

Although the B4's two feet aren't quite as premium as the stand included with LG's C Series lineup, they do the trick and still look good. There are no quality control issues with the TV, and it's built solidly.

The LG B4 OLED is far better than the TCL QM6K. The TCL's one advantage is that it is brighter in SDR, but the LG compensates with its far superior reflections handling, meaning it still looks better in brighter rooms when watching SDR content. The TCL is also capable of gaming at 144Hz and even 288Hz, far higher than the LG's 120Hz, but it can't quite match the OLED's nearly instantaneous pixel transitions. Overall, the LG is in a different league.

The LG B4 has very good SDR color volume. Its coverage of the DCI-P3 color space is outstanding, and it covers the majority of that space, only struggling a bit with some very light colors. Unfortunately, its coverage of the wider BT.2020 color space is more limited.

The LG B4 OLED provides better picture quality than the LG QNED90T. The B4 has better color accuracy and PQ EOTF tracking, so it's the more accurate TV overall. The B4 also has a quicker response time for less blur behind fast motion and lower input lag, so it's the better TV for gaming. Additionally, the B4 has better contrast that provides inky blacks, and its wide viewing angle makes it more suitable for use in a group setting.

The LG B4 has mediocre direct reflection handling. It doesn't do the best job reducing the intensity of direct reflections, so glare from lamps or windows opposite the screen is distracting.

The Samsung S90C OLED is better than the LG B4 OLED. The S90C gets brighter in HDR, so highlights pop more on it. The S90C also displays more vibrant, lifelike, and bright colors overall due to its wider color gamut and better color volume, and its better viewing angle means that there is very little color shift when watching the TV from an angle. However, the B4 has better image processing, so low-resolution and low-quality content looks better on it, and it supports Dolby Vision and DTS audio formats.

The LG B4 has outstanding pre-calibration SDR accuracy. There is a bit of too much blue and red in some shades of gray, but it's so minor that even the most keen-eyed observers won't notice it. Color temperature is incredibly close to our target of 6500K, and colors are so accurate that color enthusiasts will be pleased. Gamma is a bit off of our 2.2 target, though, with bright and dark scenes being displayed too brightly.

Unlike the LG B3 OLED, all sizes of the B4 use two wide-set metal feet instead of a stand. The feet hold the TV very well, and there is minimal wobble when the TV is pushed on. The feet lift the TV about 3.2 inches above the table, so pretty much any soundbar will fit underneath without blocking the screen. The TV comes with two plastic clips that can be attached to the feet for cable management.Footprint of the 65-inch stand: 41.6" x 9.25"

Ok thanks for the explanation. I will buy the display kit with the controller board and RA8875 shield from buydisplay.com with a Due. But I came across the similar RA8875 driver from Adafruit, which provides the PCB Eagle files that I can use later. Can I use that one as well as the RA8875 shield from buydisplay.com or is something different?

There are two settings you can use to passthrough proper chroma 4:4:4. The first is to change the input label to 'PC.' The second is to enable the '4:4:4 Passthrough' setting in the 'HDMI Settings' menu. Both of these options work the same and lock you out from using the 'Peak Brightness,' 'Noise Reduction,' 'MPEG Noise Reduction,' 'Smooth Gradation,' and 'Real Cinema' settings.

The Samsung S85F (QD-OLED version) has better color performance than the LG B4 OLED. On the other hand, the LG is a bit brighter overall, has the edge when it comes to image processing, and it supports Dolby Vision and DTS audio formats. The LG also maintains its black levels much better than the Samsung in a bright room. Inversely, the Samsung does a better job reducing the intensity of direct reflections.

The TV has a nearly instantaneous response time, resulting in incredibly clear motion with almost no blur behind fast-moving objects when watching all types of content.

The LG B4 OLED is an excellent entry-level OLED and has noticeable improvements over the LG B3 OLED. The biggest difference is its increased brightness in both SDR and HDR, which makes it more suitable for a brighter room, and it delivers a more impactful HDR experience than its predecessor. The B4 doesn't really have any direct competitors, since most OLEDs from brands like Sony, Panasonic, and Samsung are more in line with the LG C4 OLED price-wise. This makes it an excellent choice for those on a budget who need a solid TV for their home theater. It's also great for gamers looking to get their first OLED TV, especially since it has HDMI 2.1 bandwidth on all four of its ports and is available in a 48-inch model.For more options, check out our recommendations for the best OLED TVs, the best bedroom TVs, and the best 48-49-50 inch TVs.

The LG B4 has alright brightness overall. Its SDR brightness is good enough to overcome glare in a moderately lit room, but it's not bright enough for a well-lit room. Highlights in HDR content pop out enough to deliver a solid HDR experience, but the TV is too dim to fully display very bright highlights at the intended level of brightness.

The LG B4 OLED has a dark gray metal back panel that feels almost like fabric, with a matching dark gray plastic central panel that houses the inputs. Some of the inputs face the side and are close enough to the edge of the TV that they are accessible when it's wall-mounted, but the back-facing inputs are nearly impossible to reach if you have the TV mounted to the wall. If you use a mount like LG's Slim Wall Mount that mounts the TV very close to the wall, the backports are unusable unless you use a 90-degree HDMI adapter. Since one of those back-facing HDMI ports is the eARC port, this really limits you if you want to wall-mount the TV with a soundbar plugged in.

We're in the process of fixing the way we evaluate a TV's overall motion handling. This section is currently broken, and the score isn't indicative of how well a TV handles motion overall.
