LG OLED B5 vs Samsung The Frame 2025 (LS03F)

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.

The Frame LS03F is a television that can surprise with its brightness. The maximum luminance reaches around 650 nits, which already looks solid on paper. But as we know, lab tests are one thing, and real movie scenes tell a completely different story. When watching HDR content in natural conditions, The Frame 2025 maintains very good results. In most film scenes, peak brightness remained at levels of 550–650 nits. This is enough to feel the difference between standard image quality and that of HDR – bright highlights, reflections on water, and moonlight appear clear and impressive.

It’s also worth noting that the LS03F is a QLED television, which translates to solid color saturation. The coverage of the DCI-P3 color space reaches about 92%, allowing for vibrant, intense colors in HDR content. It may not be at the level of top premium models, but for a lifestyle screen, the result truly deserves recognition.

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.

When it comes to image quality right out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. In both HD and 4K HDR content, we noticed noticeable deviations in white balance. The image was heavily skewed towards red and blue, giving the screen a characteristic rosy tint. This effect was most visible in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. In such moments, the screen clearly leaned towards pink tones, which can also be seen in the attached comparison photo. As for brightness characteristics – it wasn't as bad as one might expect given such color inaccuracies. Analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically affect the perception of the material.

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.

After calibration, the movie mode gained a completely new quality. The issue of pink tint, which had previously been clearly visible, especially in bright scenes, was effectively eliminated. Colors began to look much more natural, and the white balance no longer dominated the rest of the image. It was no longer the same exaggerated “box picture” – everything gained coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, was partially corrected. Of course, this was within the limits of what the design allows without local dimming – it’s hard to speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one would expect from a mode called Filmmaker.

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.

The LS03F is equipped with the NQ4 processor, which is responsible for improving image quality—especially in lower-quality materials. In practice, it works surprisingly well, particularly with older content and recordings with lower resolution. Activating the "noise reduction" feature yields noticeable effects. The television effectively smooths tonal transitions and removes digital noise that can appear in darker areas of the image. Compared to previous generations, there is a clear improvement—previously, this feature often smoothed everything too much, including details that it shouldn't have removed. In this year's model, the smoothing still occurs, but it is done in a much more acceptable manner. Textures of materials, skin, or fabric details are no longer so heavily muted as before—the image retains more naturalness. However, this does not change the fact that film grain is still removed by the television, which may not be to everyone's liking. On the other hand, it is no longer as aggressive an intervention as in previous models. It is also worth mentioning that the LS03F may struggle with very weak signals—such as recordings from VHS tapes or video in low resolution. In such cases, we noticed slight clipping of the image at the edges—so-called overscan. This can lead to situations where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

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.

A novelty in The Frame for 2025 is the panel with a refresh rate of 144 Hz. Yes – in a television primarily associated with displaying artwork, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports action. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a 120 Hz panel and above, it allows you to adjust motion smoothness according to your own preferences. You can set a more cinematic representation while maintaining frame rate or opt for full motion smoothing. The range of options is wide, allowing you to tailor the effect to your taste – whether the viewing experience is meant to resemble classic cinema or a presentation on a modern theater panel.

*this part of the test refers to the model LS03FAU in sizes 55 and 65 inches, which is equipped with a 144Hz panel; the 43 and 50-inch sizes have 60Hz panels, and therefore perform much worse in terms of motion smoothness.

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!

As we mentioned earlier – although The Frame is likely displaying images and artwork most of the time, Samsung recognized that a Van Gogh enthusiast could just as well be an avid gamer. And it must be admitted that The Frame 2025 has almost everything it needs to become a full-fledged gaming TV.

On board, we find support for ALLM (Auto Low Latency Mode) and variable refresh rate (VRR) thanks to the implementation of one HDMI 2.1 port. The TV handles lower resolutions at higher refresh rates with ease and features an advanced Game Bar – already known from other Samsung models – which allows for a quick overview and change of the most important gaming-related settings. And for that, it earns extra points from us. The proprietary motion smoothing feature, Auto Motion Plus Game, also deserves a mention, which – and it’s worth emphasizing – works without boosting input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically unnoticeable way in terms of delays. The result? Much better fluidity in games, especially those that struggle to maintain a steady 60 frames. This solution can genuinely improve gameplay comfort in more demanding titles – especially on consoles that don’t always manage full fluidity, particularly in AAA games.

As for the downsides – the absence of Dolby Vision we already treat as a standard in Samsung TVs, so there’s not much to complain about here. The problem, however, is something completely different. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it’s gone. This is a significant hindrance when configuring the console for proper HDR content display in games. It’s hard to understand why such a decision was made, but one thing is for sure – it should be fixed as soon as possible. We are talking about a brand that has set standards in gaming on TVs for years. If HGiG returns – and we hope that it will – The Frame LS03F can confidently aspire to the title of a true gaming TV. Not only as a wall decoration but as a device that really provides enjoyment in gaming.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 lineup due to the release of software version 1131, which has restored the critical gaming feature HGiG.
