Panel type: WRGB OLED Odświeżanie: 120Hz Brand: LG Resolution: 3840x2160 System: WebOS Model year: 2025
LG B5 is the direct successor to the LG B4, and at first glance, it's clear that the two televisions have a lot in common. Design, panel, overall philosophy – all of it looks familiar. But don’t be fooled by appearances. The new model has undergone changes in a few areas that have a real impact on everyday use. What exactly are these changes? You can read about them in our full review.
LG B5 - Our verdict
7.8
Overall rating
LG B5 is a really good OLED TV that shows you don’t need to spend a fortune for very good quality. It offers deep blacks typical of organic panels, very good colour reproduction – especially after calibration – and pleasant HDR movie watching experiences. All of this makes for evening screenings that can deliver cinematic emotions even without reaching for much more expensive screens. The fluidity of the image and the set of features for gamers also deserve recognition. The 120 Hz panel, low input lag, full support for HDMI 2.1, variable refresh rate, and Dolby Vision Gaming mode make the B5 a very versatile screen – great for both gaming and watching sport. The friendly webOS system, along with the Magic remote, provides convenient access to content and makes operation easier. However, not everything is perfect. Compared to the B4 model, there is a 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 some workarounds when connecting Blu-ray players. Still, LG B5 remains one of the most sensible choices for those looking to step into the world of true cinema – without overpaying, but also without making major 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 instantly reveals its origins – here we have a good-looking, though basic model of OLED. If you’ve been following the latest generations of LG televisions, the shape of the device won’t surprise you with anything particular. The B5 stands on two metal legs positioned close to the edge – a classic, stable solution, although it doesn’t make it easier for everyone to set up the gear on a narrower TV cabinet.
The front looks very tidy – a thin, black, metal frame adds elegance to the device. However, you’ll notice more changes at the back. Yes, the "bottom" of the OLEDs is still there – the characteristic thickening that unfortunately effectively prevents a completely flat wall mount. But the material used for the back panel is a different story. The marble-like texture (almost identical to the higher C5 series) makes the B5 appear more interesting – especially if you plan to set the television centrally in the room, on its legs. We missed one thing here: better cable management. There is quite a chaos with cables at the back, which the manufacturer could have simply avoided in this class.

If you're looking for changes compared to last year's LG B4, we’ll clear up any doubts straight away – you won’t find any in this category at all. And that’s a good thing. Because how do you improve something that is already close to perfection? The LG B5, as a WOLED organic panel television, offers black scenes as dark as tar and contrast that’s hard to find even in the most expensive LCD screens. The screen is as clear as a bell – no bleeding, no streaks, no halo effects that can ruin the atmosphere in cinematic scenes. Here, everything is in its place. Details separate from black with surgical precision, nothing blurs together, even in the most demanding sequences from films like The Revenant or Oblivion. This is the type of television that can truly enchant you, especially when the room goes completely dark. When the lights go out, the LG B5 takes centre stage – and it does so wonderfully. In these conditions, OLED shines the brightest, and even top-end 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 about 500 nits of peak brightness. And interestingly, it does this even in full-screen shots flooded with white, where most OLEDs usually struggle. So, is this screen suitable for HDR films? 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 B4 model, the new B5 is darker – by about 100 nits. It may seem like a small amount, but at such average peak values, it makes a significant difference. Fortunately, the TV makes up for it with another strength – excellent coverage of the DCI-P3 and BT.2020 colour gamuts. This means HDR films look truly vibrant, lively, 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 handles HDR content – especially those created with much higher peak brightness screens in mind. Because while this OLED TV isn't one of the brightest players on the market, the end result can be pleasantly surprising. Films like Billy Lynn, Mr, and 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 muted compared to reference screens. But the amount of detail and the overall impression of the scene still make a very good impact. A large part of this is thanks to the DTM feature, which stands for dynamic tone mapping. Just like in the B4 model, it "does the job" here as well – to put it bluntly. Turning on this option helps extract more detail from the image, especially in dark scenes. Importantly – this happens without dramatic overexposure, which often occurs when using this feature. It's one of those functions that is really worth using.

On board the LG B5, you'll find HDR10 and Dolby Vision – classics in the genre. And although on paper the differences between these formats can be significant, here… they are rather symbolic. In theory, Dolby Vision should provide more – more detail in shadows, better light management, everything more “as the director intended”. But in practice – the B5 does a fantastic job even with “bare” HDR10. The dynamic tone mapping (DTM) we mentioned earlier works well enough that the difference between what you see in one format versus the other is really minimal. And that’s great news. Yes, sometimes Dolby Vision can pull something from the background or better showcase a scene with fireworks. But fundamentally – whether you’re watching a movie in HDR10 or Dolby – on the B5, it simply looks good. Cohesively, contrastively, with the right amount of detail. And that is a huge advantage. Because you don’t have to worry about what you’ve switched on and in what format.

Factory color reproduction
8.2/10
B5 was tested in Filmmaker mode and… we’d love to see more TVs like this right out of the box. Seriously. The white balance is very well set – there’s practically nothing to nitpick. Well, if you really want to, you might notice a slight deficiency in blue, which can make the overall picture have a slightly yellowish tint. But that’s just our editorial nitpicking. Most of you probably won’t even notice. We also have minimal reservations about brightness management in HDR format. The EOTF curve – which is responsible for how the TV distributes brightness across the scene – sits just below ideal. In practice, it may happen that the darkest parts of the image appear too dark and simply… disappear. But these are details that only come out in measurements. Generally: we are impressed. But we also know that LG TVs respond very well to professional calibration. You can extract nearly reference-quality picture from them, so – although it’s already very good out of the factory – we took the liberty to go a step further and fine-tune everything to the max.
Color reproduction after calibration
9.1/10
We have to admit that we didn't have much work with the LG B5. It's one of those TVs that look good right from the start, but after calibration… they can really impress. The white balance was nearly perfect – down to a level of errors invisible to the human eye, unless you're a professional colourist with a magnifying glass at the screen. We also managed to control the TV's tendency to slightly dim the darkest details, especially in HDR scenes. After proper tuning, everything looks cohesive: blacks remain deep but don't swallow information. Highlights maintain a natural sparkle, and colours are true to the director's vision. This is truly one of those models that show you don't have to spend a fortune to have an almost reference-quality image. If you can opt for professional calibration – it's definitely worth it for the B5.
LG B5 - Smoothness of tonal transitions
7.2/10
LG B5 handles colour gradation quite decently. In bright scenes, where we have smooth transitions between skin tones, the sky or background, the TV blends colours seamlessly and without hiccups. At first glance – it’s good, particularly considering the price. But just reach for more challenging material – those darker, more demanding scenes with a lot of subtle transitions – and the problems begin. Small artifacts appear, false contours, slight thickening. It’s still not at a level that blinds 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 handling lower quality content. Thanks to the enhancement and smoothing features, HD or even SD materials come to 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 in place, film grain doesn’t disappear, and the edges of objects don’t look washed out 😉. It’s a really useful tool – especially if you’re watching free-to-air TV, archival materials, or content from YouTube in lower resolutions. The picture is clear, consistent, and simply pleasant to the eye.
Upgrading as such works very well – even low-quality content is reproduced with surprising fidelity. Unfortunately, it’s not without a minor hiccup. Although the menu has an option to turn off overscan, the television still has issues correctly displaying very low-resolution images. It’s a minor detail, but when watching older materials – it can be annoying.
LG B5 - Blur and motion smoothness
8.5/10
Maximum refresh rate of the panel: 120Hz
Film motion smoothing option: Yes
Blur reduction option: Yes
BFI function 60Hz: Yes, 60Hz (image flickers)

LG B5 is a TV with a 120 Hz OLED panel. It may not sound as impressive as the marketing terms "144 Hz" or "165 Hz" commonly found in gaming monitors, but honestly? The smoothness is still excellent. The picture is sharp, fluid, and simply enjoyable to watch – even when there’s a lot happening on screen. The organic panel does its job – the pixel response time is almost instantaneous, which means there’s no risk of ghosting or blurring that can ruin dynamic shots. Sports, fast-paced games – everything looks clear and distinct.
We also have the classic LG motion smoother, TruMotion. It allows you to smooth out movies shot at 24 frames – in other words, most of what you watch on Netflix or from Blu-ray discs. If you set lower values on the “De-Judder” slider, you’ll get a picture 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 to your liking.
Blur (native resolution, maximum refresh rate):
As befits an organic screen, the LG B5 has absolutely no issue with motion blur. In our test with the classic "little green man", the image remained incredibly sharp even at the highest refresh rate of 120 Hz. Pixels respond instantly, so there's no question of any blurring or stretching during motion. It's just one of those things that OLEDs do better than most LCD screens – and the B5 is no exception.

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

LG B5 - Compatibility with PC
7.6/10
Chroma 444 (maximum resolution and refresh rate): Yes
Font clarity: Good
Readability of dark text and shapes: Very Good

Matrix subpixel arrangement: RWBG
Max refresh rate: 120Hz
G-Sync: Yes
LG B5 is a television that communicates well with a computer. You won't find gaming features like 144 or 165 Hz here, but is that really necessary for anyone? Thanks to the 120 Hz panel, low input lag, and G-Sync support, it's actually a very good screen for gaming on PC. No stuttering, no tearing, with instant response.
But it's not just for gaming. The B5 can also be quite comfortable for... simply working. The television correctly supports chroma 4:4:4, so fonts are legible, interfaces are clear, and your eyes won't hurt from blurry text. This isn't 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 arrangement can cause a slight shadow at the edges of fonts. This isn't something that stands out from the couch. It's more likely to be noticed by someone sitting close to the screen and spending half a 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 you would expect from a WOLED panel. No matter from which side you sit, the picture retains its quality. Colours don't fade, contrast doesn't drop off sharply, and details remain clearly visible. However, it must be honestly added that this is not the level of QD-OLEDs from Samsung Display. Those manage to hold colour saturation even better under extreme angles. But if you don't plan on watching films while sitting at a 90-degree angle – the B5 is more than sufficient. It's one of those TVs that is just pleasing to look at – from any side.
LG B5 - TV efficiency during daytime
4.9/10
Matrix coating: Glare
Reflection suppression: Decent
Black levels during daytime: Very Good
The LG B5 is a television that feels best after dark. But when the sun comes in, it becomes a bit of a challenge. The brightness of this model is rather average, and the anti-reflective layer… also average. There are no special coatings here that deal well with reflections or very bright daylight. So if you're planning to place this television opposite a large, uncovered window – it may simply be hard to see anything.
Fortunately, there is something worth praising: the glossy WOLED panel maintains good colour saturation. Even in difficult conditions, the image doesn't fade or become "washed out," as can happen with some television models. In general, it's watchable, but if you're looking for a television specifically "for a bright lounge room," the B5 shouldn't be your first choice.

Functional Features
Even though the LG B5 is modern equipment, it hasn’t forgotten those who simply want to... watch television. No apps, no accounts, no logging in anywhere. We have built-in DVB-T2 tuners and the ability to record onto USB, with a clear and fast EPG guide. Is that not enough? There’s even a working teletext – for many, surely a relic, for others, a daily occurrence. A plus is also the option to turn off the picture and just keep the sound, which works great for listening to music. And if you want to watch quietly – you can easily pair Bluetooth headphones, without wrestling 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 you control it. The Magic remote, which we get with the LG B5 (in our version B56 – the one without the numeric keypad), works like a magic wand. We point, click, select. And it simply... works. Intuitively, quickly, and without unnecessary clicking left and right. Added to this is the AI voice assistant – quite efficient. You can summon it directly from the remote and use your voice to search for content, change settings or switch sources. WebOS may not be the most "modern" system on the market, and built-in ads can be annoying, but when it comes to ease of use – especially with the Magic remote – it still stays one step ahead of the competition.

LG B5 handles USB files as it should. Most popular formats work seamlessly, and subtitles – even with Polish characters – are displayed correctly. You can comfortably play a movie from a USB drive or have a weekend slideshow of your holiday 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 the LG C5 had no issues with them, the B5 stubbornly refused to cooperate and was unable to display them. A little hiccup 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, just like the majority of flat-screen TVs. And yet – it actually sounded quite nice. The dialogues are clear, the sound isn't booming, and during a quieter viewing, we didn't immediately feel the need to plug in a soundbar. It's just a shame that this year LG decided to cut something that worked in the previous generation. We're of course talking about support for DTS formats, which we won't find in the B5. If you have movies encoded in that format – you'll need to rely on an external player.
