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 model, and at first glance, it is clear that both televisions share a lot in common. Design, panel, overall philosophy – all of it looks familiar. But don't be deceived by appearances. The new model has undergone changes, and in several areas, which have a real impact on everyday usage. What exactly? You will read about it in our full test.
LG B5 - Our verdict
7.8
Overall rating
LG B5 is really a good OLED television, which shows that you don't have to spend a fortune for very good quality. It offers deep blacks typical of organic panels, very good colour reproduction – especially after calibration – and enjoyable HDR movie watching experiences. All of this means that evening screenings can provide cinema-like emotions even without resorting to much more expensive screens. The smoothness 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 – both for gaming and watching sports. The friendly webOS system with a Magic remote adds to the package, providing convenient access to content and simplifying operation. However, not everything is perfect. Compared to the B4 model, a slight drop in brightness can be noticeable, especially in very bright rooms. For some users, the lack of DTS audio support may also be a problem, which could force some workarounds when connecting Blu-ray players. Despite this, LG B5 remains one of the most sensible choices for those who want to enter the world of true cinema – without overspending, but also without major compromises. It's a screen that doesn’t need to prove anything – it simply delights the eye with excellent picture quality and works as it should.

LG OLED B5 is a television that immediately reveals its origins – we are dealing here with a good-looking, albeit basic OLED model. If you have been following the successive generations of LG televisions, the shape of the device will not surprise you with anything special. The B5 stands on two metal legs positioned close to the edge – a classic, stable solution, although it may not make it easier for everyone to place the equipment on a narrower TV cabinet.
The front looks very tidy – a thin, black, metal bezel adds elegance to the device. However, you will notice more changes at the back. Yes, the "bum" of OLEDs is still there – the characteristic bulge that unfortunately effectively 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 in 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, which the manufacturer could easily have avoided in this class.

If you are looking for changes compared to last year's LG B4, we will immediately dispel any doubts – you won't find any in this category at all. And that's good. Because how to improve something that is already bordering on perfection? The LG B5, as a television with an organic WOLED panel, offers black as tar scenes and a contrast that is hard to find even in the most expensive LCD screens. The display is as clear as a bell – no bleed-through, no streaks, no halo effects that can ruin the atmosphere in cinema scenes. Here, everything is in its place. Details separate from the black with surgical precision, nothing blends together, even in the most demanding sequences from films such as The Revenant or Oblivion. This is the type of television that can enchant you, especially when the room goes completely dark. When the lights go out, the LG B5 takes centre stage – and it does so spectacularly. In these conditions, OLED shines the brightest, and even top LCD models – despite advanced dimming and hundreds of zones – simply fall behind.

The LG B5 is a moderately bright OLED television. Regardless of the scene, it can generate around 500 nits of peak brightness. Interestingly, it achieves this even in full-screen shots saturated with white, where most OLEDs typically struggle. So is this screen suitable for HDR films? Indeed – and very much so, because such brightness allows you to truly feel the magic of HDR effects. However, it is 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 quite a significant difference. Fortunately, the television compensates with another advantage – excellent coverage of the DCI-P3 and BT.2020 colour gamut. As a result, HDR films look really colourful, vibrant, and impress 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 – particularly those created for screens with significantly higher peak brightness. While this OLED television is not among the brightest players on the market, the final effect can be pleasantly surprising. Films like Billy Lynn, Pan, 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 subdued compared to reference screens. But the amount of detail and the overall impression of the scene still make a very good impact. Much of this is due to the DTM function, or dynamic tone mapping. Similar to the B4 model, it "gets the job done" here as well – to put it plainly. Activating this option helps to extract more details from the image, especially in dark scenes. Importantly – this happens without dramatic over-saturation of the image, which often occurs when using this option. This is one of those features that is truly worth using.

On board the LG B5, you will find HDR10 and Dolby Vision – the classics of the genre. And although on paper the differences between these formats can be quite significant, here… they are rather symbolic. In theory, Dolby Vision should offer more – more detail in the shadows, better light handling, everything more “as the director intended”. But in practice – the B5 does an excellent job even with “bare” HDR10. The dynamic tone mapping (DTM) we mentioned earlier works so well that the difference between what you see in one format and the other is really minimal. And that is very good news. Yes, sometimes Dolby Vision can pull something out of the background or represent a scene with fireworks better. But fundamentally – whether you are watching a film in HDR10 or in Dolby – it simply looks good on the B5. Cohesively, with contrast, and with the right amount of detail. And that is a huge advantage. Because you don’t have to worry about what you have switched on and in which format.

Factory color reproduction
8.2/10
We tested the B5 in Filmmaker mode and... we would love to see more TVs like this straight out of the box. Truly. The white balance is set very well – there's practically nothing to complain about. Well, if one were to nitpick, one might notice a slight deficiency in blue, which makes the overall image seem slightly yellowish. But that’s just our editorial quibbling. Most of you probably wouldn’t even notice it. We also have minimal reservations about brightness management in HDR format. The EOTF curve – which is responsible for how the TV distributes brightness in a scene – is slightly below ideal. In practice, it may happen that the darkest parts of the image are displayed too dark and simply… disappear. But these are details that only come out in measurements. Generally: we are impressed. However, we also know that LG TVs respond very well to professional calibration. You can achieve almost reference-quality picture from them, so – while it's already very good out of the box – we allowed ourselves to go a step further and refine 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 televisions that look good right from the start, but after calibration… they can really impress. The white balance was brought to almost perfect levels – to the point of errors that are invisible to the human eye, unless you are a professional colourist with a magnifying glass at the screen. We also managed to master the tendency of the television to slightly dim the darkest details, particularly in HDR scenes. After proper tuning, everything looks cohesive: black remains deep but does not consume information. Highlights maintain their natural sparkle, and colours align with the director's vision. This is truly one of those models that shows you don't have to spend a fortune to have an almost reference-quality picture. If you can opt for professional calibration – it’s definitely worth it in the case of the B5.
LG B5 - Smoothness of tonal transitions
7.2/10
The LG B5 handles colour gradation quite decently. In bright scenes, where we have smooth transitions between skin tones, the sky, or backgrounds, the television blends colours seamlessly and without any jarring effects. At first glance – it looks good, especially considering the price. However, it is enough to reach for more challenging material – those darker, more demanding scenes with a lot of subtle transitions – and the challenges begin. Minor artefacts, false contours, and slight thickening appear. It is still not a level that dazzles or distracts from the narrative, 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 positively surprised us in terms of handling lower quality content. Thanks to the enhancement and smoothing features, materials in HD resolution or even SD gain a second life. Importantly – when this option is activated at the "low" or "medium" level, we do not feel that the image is artificially softened or smoothed out unnecessarily. Details remain intact, film grain does not disappear, and the edges of objects do not look washed out 😉. This is truly a useful tool – especially if you are watching terrestrial television, archival materials, or content from YouTube in lower resolutions. The image is clear, coherent, and simply pleasant to the eye.
Scaling as such works very well – even content of poor quality is reproduced with surprising fidelity. Unfortunately, there was a slight hiccup. Although the menu contains the option to disable overscan, the television still has issues with correctly displaying images of very low resolution. It may seem like a detail, but when watching older materials – it can be irritating.
LG B5 - Blur and motion smoothness

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

LG B5 is a television with a 120 Hz OLED panel. It may not sound as impressive as the marketing claims of “144 Hz” or “165 Hz” found in gaming monitors, but honestly? The smoothness is excellent nonetheless. The picture is sharp, fluid and simply enjoyable to watch – even when there is a lot happening on screen. The organic panel does its job – the pixel response time is almost instantaneous, meaning there’s no sign of smearing or blurring that can spoil dynamic shots. Sport, fast-paced games – everything looks clear and distinct.
We also have the classic LG smoothness enhancer, TruMotion. This allows you to smooth out films shot at 24 frames per second – which, to put it bluntly, is 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 a cinematic look – with a slight judder, but without any artificiality. Higher settings? A soap opera effect is guaranteed. Fortunately, LG gives you the option to tune everything to your liking.
Blur (native resolution, maximum refresh rate):
As befits an organic screen, the LG B5 has absolutely no problem with motion blur. In our test with the classic "alien" image, the picture remained incredibly sharp even at the highest refresh rate of 120 Hz. The pixels react instantaneously, so there is no question of any blurring or stretching in 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, in practice, don’t understand what that means. The LG B5 is not one of them. Everything here is spot on – there are four HDMI 2.1 ports, it has 120 Hz, VRR, and ALLM, and it even has a Game Bar that is actually useful, not just looks good in the brochure. 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 this is not in the sense of “theoretically supports”; it really turns on, looks good, and you don’t need to fiddle with the settings for half an hour. Additionally, there’s the HGiG picture mode that LG implemented correctly – which means HDR in games doesn’t turn the screen into a flash lamp, 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. Cheers to the LG B5!
LG B5 - Input lag
9.9/10
Here we won't elaborate – the LG B5 simply has excellent 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 cannot be fairly critiqued. It simply works instantly, with no delays, no surprises. Well… almost. Because as usual, there is a small asterisk with the Dolby Vision Gaming mode. In this mode, the response time slightly increases. It’s nothing dramatic – they are still very low values, hardly noticeable during gameplay – but if you play exclusively competitive titles and fight for every millisecond on the XBOX, it’s worth keeping in mind.

LG B5 - Compatibility with PC

Chroma 444 (maximum resolution and refresh rate): Yes
Font clarity: Good
Readability of dark text and shapes: Very Good
Input lag in PC mode (4K, maximum refresh rate): 5ms
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 frills 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 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 television properly supports chroma 4:4:4, so fonts are readable, interfaces are clear, and your eyes won't hurt from blurred letters. This isn't a given, even among more expensive models. However, there is one 'but' – and this applies not only to the B5, but to any OLED with a WOLED panel. The RWGB subpixel arrangement can cause a slight shadow along the edges of fonts. This isn't something that stands out from the sofa. It's something that someone sitting with their nose to the screen and spending half the day in Excel would notice.
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 an WOLED panel. No matter from which side you sit, the picture maintains its quality. The colours do not wash out, the contrast does not deteriorate, and the details remain clearly visible. However, it must be said that this is not the level of Samsung Display's QD-OLEDs. Those can hold colour saturation even better at extreme angles. But if you do not plan on watching films while sitting at a 90-degree angle – the B5 is more than sufficient. It is one of those televisions that is simply pleasant to look at – from every angle.
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 feels best after dark. But when the sun comes out, it becomes a challenge. The brightness of this model is rather average, and the anti-reflective layer... also average. There are no special coatings here that handle reflections or very bright daylight well. So if you plan to place this television opposite a large, uncovered window – it could simply be difficult to see anything.
Fortunately, there is something worth praising: the glossy WOLED panel maintains colour saturation well. Even in difficult conditions, the image does not fade and does not become "washed out," as can happen with some models of televisions. Generally, it is watchable, but if you are looking for a television specifically "for a bright living room," then the B5 should not be your first choice.

User features
Although the LG B5 is modern equipment, it hasn't forgotten about those who sometimes just want to... watch television. Without apps, without accounts, without logging in anywhere. It comes with built-in DVB-T2 tuners and the ability to record onto USB, along with a clear and fast EPG guide. Is that not enough? There’s even a working teletext – for many, probably a relic, for others, a daily necessity. We also appreciate the option to turn off the picture and leave just the sound, which is great for listening to music. And if you want to watch quietly – you can easily pair Bluetooth headphones, without a struggle with settings and without delays. Everything works as it should.
SMART TV: webOS
The biggest distinguishing feature of the webOS system – still! – is the way it is controlled. The Magic remote that comes with the LG B5 (in our version B56 – without a numeric keypad) works like a magic wand. You point, click, select. And it simply… works. Intuitively, quickly, and without unnecessary side-to-side clicking. Additionally, there’s an 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 the built-in ads can be annoying, but when it comes to user convenience – especially with the Magic remote – it still outpaces the competition by a step.

LG B5 handles files from USB as it should. Most popular formats work flawlessly, and subtitles – even with Polish characters – are displayed correctly. You can easily play a movie from a USB stick or have a weekend slideshow of your holiday photos without worrying that something will go wrong. However, there was a surprise with HEIC format files – 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 minor hiccup that probably won't affect everyone, but it's worth knowing about.

We weren't expecting 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 televisions. And yet – it sounded really pleasant. The dialogues are clear, the sound doesn’t boom, and during a calmer viewing, we didn’t immediately feel the need to connect a soundbar. It's a pity 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 will no longer find in the B5. If you have films encoded in this format – you'll need to rely on an external player.
