LG B5 is the direct successor to the LG B4 model, and at first glance, it's obvious that the two televisions have a lot in common. The design, the panel, the overall philosophy – all of this feels familiar. But don't be fooled by appearances. The new model has undergone changes, and in several areas, which have a real impact on everyday use. What exactly? You can read about it in our full review.
LG B5 - Our verdict
7.8
Overall rating
LG B5 is truly a great OLED television that shows you don't need to spend a fortune for very good quality. It offers deep blacks typical of organic panels, excellent color reproduction—especially after calibration—and enjoyable HDR movie watching experiences. All of this makes evening viewings capable of delivering cinematic emotions without reaching for significantly more expensive screens. The fluidity of the picture and the set of features for gamers also deserve recognition. A 120 Hz panel, low input lag, full support for HDMI 2.1, variable refresh rates, and Dolby Vision Gaming mode make the B5 a very versatile screen—for both gaming and watching sports. It is complemented by a user-friendly webOS system with a Magic remote that provides convenient access to content and simplifies operation. However, not everything is perfect. Compared to the B4 model, there is a noticeable slight drop in brightness, especially in very bright rooms. For some users, the lack of DTS audio support may also pose a problem, which could necessitate workarounds when connecting Blu-ray players. Despite this, LG B5 remains one of the most sensible choices for those looking to enter the world of true cinema—without overpaying but also without significant compromises. It’s a screen that doesn't need to prove anything—it simply delights the eye with great picture quality and works as it should.

LG OLED B5 is a television that immediately reveals its origins – we are dealing with a good-looking, albeit basic, OLED model. If you’ve been following the latest generations of LG televisions, the shape of the device won’t surprise you with anything special. The B5 stands on two metal legs positioned close to the edges – a classic, stable solution, though it may not make it easier for everyone to set up the equipment on a narrower TV stand.
The front looks very neat – a thin, black metal frame adds elegance to the device. However, you’ll notice more changes at the back. Yes, the "rear end" of the OLEDs is still there – the characteristic bulge that unfortunately prevents a completely flat wall mount. But the material used for the rear panel is another story. The marble-like texture (almost identical to that of the higher C5 series) makes the B5 look more interesting – especially if you plan to place the television centrally in the room, on its legs. We missed one thing here: better cable management. The back is rather chaotic with cables, something the manufacturer should have simply avoided in this class.

If you're looking for changes compared to last year's LG B4, we'll dispel any doubts right away - you won't find any in this category at all. And that's a good thing. Because how do you improve something that already borders on perfection? The LG B5, as is fitting for an organic WOLED screen, offers pitch-black scenes and contrast that's hard to find even in the most expensive LCD displays. The screen is as clear as a tear – no bleed-through, no smudges, no halo effects that can ruin the atmosphere in cinematic scenes. Everything is in its place here. Details separate from the black with surgical precision, nothing blends together, even in the most demanding sequences from movies like The Revenant or Oblivion. This is the type of TV that can enchant you especially when the room goes completely dark. When the lights go out, the LG B5 takes center stage – and it does so magnificently. In these conditions, OLED shines the brightest, and even top LCD models – despite advanced dimming and hundreds of zones – simply fall behind.

LG B5 is a moderately bright OLED TV. Regardless of the scene, it can generate around 500 nits of peak brightness. And interestingly, it does this even in full-screen shots flooded with white, where most OLEDs usually fall short. So, is this screen suitable for HDR movies? Yes – absolutely, because such brightness really allows you to feel the magic of HDR effects. However, it's worth noting that compared to last year's model B4, the new B5 is darker – by about 100 nits. It may seem like a small difference, but at such average peak values, it makes quite a significant difference. Fortunately, the TV makes up for it with another advantage – excellent coverage of the DCI-P3 and BT.2020 color gamut. As a result, HDR movies look really colorful, vibrant, and impressive even in more demanding scenes.
Scene from the movie “Pan” (about 2800 nits)
Scene from the movie “Billy Lynn” (about 1100 nits)
We checked how the LG B5 performs with HDR materials – especially those created with much higher peak brightness screens in mind. Because although this OLED TV is not among the brightest players on the market, the final result can be pleasantly surprising. Films such as Billy Lynn, Pan, or The Meg – productions that often push HDR systems to their limits – look really good on the B5. Of course, the brightest effects – explosions, fireworks, light reflections – are somewhat subdued compared to reference screens. But the amount of detail and the overall impression of the scene still make a very good impression. A big part of this is thanks to the DTM function, or dynamic tone mapping. Just like in the B4 model, it also "does the trick" here – to put it bluntly. Turning on this option helps to bring out more details from the image, especially in dark scenes. Importantly – this happens without dramatic overemphasis of the image, which often occurs when using this option. It’s one of those features that is truly worth using.

On board the LG B5, you'll find HDR10 and Dolby Vision – classic options. And while on paper the differences between these formats can be significant, here... they are rather symbolic. In theory, Dolby Vision should provide more – more details in the shadows, better control of the lights, everything more "as the director intended." But in practice – the B5 does a great job even with "bare" HDR10. The dynamic tone mapping (DTM) we've mentioned earlier works well enough that the difference between what you see in one format versus the other is truly minimal. And that's very good news. Sure, sometimes Dolby Vision can pull something out of the background or show a fireworks scene better. But basically – whether you're watching a movie in HDR10 or in Dolby – on the B5 it simply looks good. Cohesively, contrastively, with the right amount of detail. And that's a huge advantage. Because you don't have to worry about what you've turned on and in what format.

Factory color reproduction
8.2/10
We tested the B5 in Filmmaker mode and... we would like to see more TVs like this straight out of the box. Really. The white balance is set very well – there is practically nothing to complain about. Well, if one were to be very picky, one might notice a slight deficiency in blue, which makes the overall picture have a slightly yellowish tint. But that’s just our editorial nitpicking. Most of you probably won't even notice it. We also have some minor reservations about brightness management in HDR format. The EOTF curve – that is, the one responsible for how the TV distributes brightness in a scene – is slightly below the ideal. In practice, it can happen that the darkest parts of the image may be displayed too dark and simply... disappear. But these are details that only come out in measurements. Overall: we are impressed. But we also know that LG TVs respond very well to professional calibration. They can produce nearly reference-quality images, so – even though it's already very good out of the box – we allowed ourselves to take an extra step and fine-tune everything to perfection.
Color reproduction after calibration
9.1/10
We must admit that we didn't have much work with the LG B5. It's one of those TVs that looks good right from the start, but after calibration… it can really impress. The white balance was brought to almost perfect levels – to a degree of error invisible to the human eye, unless you are a professional colorist with a magnifying glass at the screen. We also managed to control the TV's slight tendency to dim the darkest details, especially in HDR scenes. After proper tuning, everything looks coherent: the black is still deep, but not information-hungry. The highlights retain a natural sparkle, and the colors align with the director's vision. It's really one of those models that show you don't have to spend a fortune to get almost reference-quality image. If you can decide on professional calibration – it's definitely worth it for the B5.
LG B5 - Smoothness of tonal transitions
7.2/10
LG B5 handles color gradation quite decently. In bright scenes, where we have smooth transitions between skin tones, the sky, or backgrounds, the television merges colors seamlessly and without issues. At first glance – it's good, especially considering the price. But it's enough to reach for more challenging material – those darker, more demanding scenes with a lot of subtle transitions – and the problems begin. Minor artifacts, false contours, slight bumps appear. It's still not a level that stands out or distracts from the plot, but the difference compared to more expensive WOLED models – and even more so QD-OLED screens – becomes noticeable.
Image scaling and smoothness of tonal transitions
7.5/10
Smooth transition function
Image without overscan on the SD signal
LG B5 really surprised us positively in terms of dealing with lower quality content. Thanks to the enhancement and smoothing features, HD or even SD materials get a new life. Importantly – when this option is turned on at the "low" or "medium" level, we don't get the impression that the image is artificially softened or overly smoothed. Details remain intact, film grain does not disappear, and object edges do not look washed out 😉. It's a really useful tool – especially if you watch terrestrial TV, archival materials, or content from YouTube in lower resolutions. The image is clean, cohesive, and simply pleasant to the eye.
Upscaling as such works very well – even content of poor quality is rendered with surprising fidelity. Unfortunately, there was a small hiccup. While the menu offers an option to turn off overscan, the television still struggles to display very low-resolution images correctly. It’s a minor detail, but when watching older materials – it can be annoying.
LG B5 - Blur and motion smoothness

Maximum refresh rate of the panel: 120Hz
Film motion smoothing option: Yes

The LG B5 is a television with a 120 Hz OLED panel. It may not sound as impressive as the marketing terms "144 Hz" or "165 Hz" found in gaming monitors, but honestly? The smoothness is still excellent. The picture is sharp, smooth, and simply enjoyable to watch – even when there’s a lot happening on the screen. The organic panel does its job – the pixel response time is nearly instantaneous, which means there’s no blurring or smearing that can ruin dynamic shots. Sports, fast-paced games – everything looks clear and distinct.
We also have LG's classic motion smoother, TruMotion. This feature allows you to smooth out films shot at 24 frames per second – in other words, most of what you watch on Netflix or on Blu-ray discs. If you set the “De-Judder” slider to lower values, you'll get an image closer to the cinematic experience – with a slight judder, but without artificiality. Higher settings? Soap opera effect guaranteed. Fortunately, LG gives you the choice, and you can tune everything as you like.
Blur (native resolution, maximum refresh rate):
As expected from an organic display, the LG B5 has absolutely no problem with smearing. In our test with the classic "little green man" image, the picture remained incredibly sharp even at the highest refresh rate, which is 120 Hz. Pixels respond instantly, so there is no question of any smears or stretching during motion. It's simply one of those things that OLEDs do better than most LCD screens – and the B5 is no exception.

There are already a few televisions on the market with the label "for gamers" that don’t really understand what that means. The LG B5 is not one of them. Everything here is right – there are four HDMI 2.1 ports, it has 120 Hz, VRR and ALLM, and it also has a Game Bar that is actually useful, not just looks good in the promotional folder. You connect your console – it works. You set 4K at 120 Hz – it works. You have an Xbox and want to play in Dolby Vision – it works too. And not in the sense of "it theoretically supports it," but rather it really turns on, looks good, and you don’t have to fiddle with the settings for half an hour. On top of that, there’s the HGiG picture mode, which LG has implemented correctly – meaning that HDR in games doesn’t turn the screen into a flashlight but shows exactly what it should. There are no surprises here, no strange limitations, no "buts." And you know what? That’s how it should be. Kudos to the LG B5!
LG B5 - Input lag
9.9/10
Here, we won't elaborate – the LG B5 simply has fantastic input lag. For 60 Hz content, it scores below 10 ms, and for 120 Hz, it even drops to around 5 ms. These are values that you can't honestly complain about. It just works instantly, without delays, without surprises. Well… almost. Because as usual, there's a small asterisk with the Dolby Vision Gaming mode. In this mode, the response time slightly increases. It's nothing dramatic – these are still very low values, rather imperceptible while gaming – but if you're playing exclusively tournament titles and fighting for every millisecond on the XBOX, it's worth keeping in mind.

LG B5 - Compatibility with PC
7.6/10
Chroma 444 (maximum resolution and refresh rate): Yes

LG B5 is a TV that works great with a computer. You won't find gaming features like 144 or 165 Hz here, but is that really necessary for anyone? With a 120 Hz panel, low input lag, and G-Sync support, it’s truly a very good screen for gaming on PC. No stuttering, no tearing, with lightning-fast response.
But it’s not just for gaming. You can also quite comfortably... simply work on the B5. The TV correctly supports chroma 4:4:4, so fonts are readable, interfaces are clear, and your eyes won’t hurt from blurred letters. This is not obvious, even among more expensive models. However, there is one “but” – and this applies not only to the B5 but to every OLED with a WOLED panel. The RWGB subpixel layout can cause a slight shadow at the edges of fonts. This is not something that stands out from the couch. It’s more likely to be noticed by someone sitting with their nose to the screen and spending half the day in Excel.
LG B5 - Viewing angles
7.4/10
Brightness drop at an angle of 45 degrees: 31%
In terms of viewing angles, the LG B5 performs very well – exactly as one would expect from a WOLED panel. No matter from which side you sit, the image retains its quality. The colors do not fade, the contrast does not drop significantly, and the details remain clearly visible. However, it must be honestly added that this is not the level of Samsung Display's QD-OLEDs. They manage to hold color saturation even better at extreme angles. But if you do not plan to watch movies sitting at a 90-degree angle – the B5 is more than sufficient. It’s one of those TVs that simply looks good from every side.
LG B5 - TV efficiency during daytime
4.9/10
Matrix coating: Glare
Reflection suppression: Decent
Black levels during daytime: Very Good
LG B5 is a television that performs best after dark. But when sunlight comes in, it becomes a challenge. The brightness of this model is rather average, and the anti-glare layer... is also average. There are no special coatings that deal with reflections or very bright daylight. So if you plan to place this television opposite a large, uncovered window – it might just be hard to see anything.
Fortunately, there is something worth praising: the glossy WOLED panel maintains color saturation well. Even in difficult conditions, the image doesn’t fade or become "washed out," as can happen with some television models. Generally, it is watchable, but if you are looking for a television specifically "for a bright living room," then the B5 shouldn't be your first choice.

User Features
Although the LG B5 is modern equipment, they haven't forgotten about those who just want to… watch television sometimes. Without apps, without accounts, without logging in anywhere. We have built-in DVB-T2 tuners and the ability to record to USB, with a clear and fast EPG guide. Not enough? There’s even a functioning teletext – a relic for many, perhaps, but everyday life for others. We also appreciate the option to turn off the picture and leave just the sound, which works great for listening to music. And if you want to watch quietly – you can easily pair Bluetooth headphones, without struggling with settings and without delays. Everything works as it should.
SMART TV: webOS
The biggest distinguishing feature of the webOS system – still! – remains the way of control. The Magic remote that comes with the LG B5 (in our version B56 – the one without a numeric keypad) works like a magic wand. We point, click, select. And it just… works. Intuitively, quickly, and without unnecessary left-right arrow clicking. Additionally, there’s an AI voice assistant – quite capable. You can call it directly from the remote and use your voice to search content, change settings, or switch sources. While webOS itself may not be the most "modern" system on the market, and the built-in ads can be annoying, when it comes to user convenience – especially with the Magic remote – it still keeps a step ahead of the competition.

LG B5 handles files from USB as it should. Most popular formats work seamlessly, and subtitles – even with Polish characters – are displayed correctly. You can easily play a movie from a flash drive or do a weekend slideshow of your vacation photos without worrying that something will go wrong. However, there was a surprise with files in HEIC format – that is, photos saved by Apple devices. While LG C5 had no issues with them, the B5 stubbornly refused to cooperate and was unable to display them. A minor glitch that probably won’t affect everyone, but it's worth knowing about.

We didn't expect miracles – after all, the LG B5 doesn't have an advanced audio system, and its built-in speakers look... well, like those in most flat-screen TVs. And yet – it sounds quite pleasant. Dialogs are clear, the sound doesn't boom, and during a quieter viewing experience, we didn't immediately feel the need to connect a soundbar. It's just a pity that this year LG decided to cut something that worked in the previous generation. We're talking, of course, about support for DTS formats, which we won't find in the B5. If you have movies encoded in that standard – you'll need to rely on an external player.
