SAMSUNG S90F (WOLED) vs Samsung The Frame 2025 (LS03F)

Does the S90F handle not only black, but also bright parts of the image? Definitely yes. Tales of OLEDs as “dark screens” can slowly be regarded as a myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value entirely sufficient to enjoy impressive and dynamic HDR imagery – both in films and series. Most of the scenes we tested look superb, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test pattern from the film The Meg (picture 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be considered that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

The Frame LS03F is a television that can surprise with its brightness. The maximum luminance reaches around 650 nits, which already looks impressive on paper. But as we know, laboratory tests are one thing, and real film scenes are quite another. When watching HDR materials in natural conditions, The Frame 2025 maintains very good results. In most film scenes, the peak brightness remained at around 550–650 nits. This is a sufficient value to feel the difference between standard picture quality and that of HDR – bright highlights, reflections on water, or moonlight are presented clearly and spectacularly.

It is also worth remembering that the LS03F is a QLED television, which translates into solid colour saturation. The coverage of the DCI-P3 colour space reaches about 92%, allowing for vibrant, intense colours in HDR content. This is not the level of top premium models, but for a lifestyle screen, the result truly deserves recognition.

The Samsung S90F, like most modern televisions, offers many picture modes, but – in line with our testing tradition – we assessed it in the best one, which is the Filmmaker mode. This way, the image looks significantly more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially muted – just closer to what should be seen. Of course, "more correct" does not mean "ideal". Unfortunately, our S90F unit had considerable issues with white balance, especially in the blue range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more "cinematic" – because it is warmer – but let's not kid ourselves, George Lucas did not film Star Wars in sepia 😉 (you will find the comparison with the scene as always below).

Additionally, in HDR materials, there was a noticeable issue with brightness management. The EOTF curve showed a clear "spike" in brightness – the television brightened the image more than it should have, which made some effects look overly intense and diverged from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you will read about its effects later in the review.

When it comes to image quality straight out of the box, even in Filmmaker mode, which is supposed to be the closest to reference, there were issues. We noticed clear deviations in white balance in both HD and 4K HDR content. The image was heavily skewed towards red and blue, giving the screen a characteristic pinkish tint. This effect was most noticeable in bright scenes – for example, in shots with a lot of white, where neutral light should naturally dominate. At such moments, the screen clearly took on pink tones, which is also visible in the attached comparison photo. As for the brightness characteristics – it wasn’t as bad as one might expect with such colour inaccuracies. The analysis of the gamma curve and EOTF showed a slight brightening of the image compared to the reference, but not enough to drastically ruin the viewing experience.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older films in SDR quality finally look as they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics returns to its rightful place (you’re welcome, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Yes, the most demanding users may spot minimal deviations in brightness, but honestly – most viewers won’t even notice that. And it's no wonder, because the vast majority of errors are below a ΔE value of 3, which is below the threshold of visibility. After calibration, the S90F (WOLED) truly becomes an excellent display – one that provides nearly perfect picture quality.

After calibration, the movie mode has gained a completely new quality. The issue of the pink tint, which had been clearly visible before, especially in bright scenes, has been effectively eliminated. Colours now look much more natural, and the white balance no longer dominates the rest of the image. It is no longer the same exaggerated "box picture" – everything now has coherence and a cinematic character. Additionally, the tendency of the television to slightly brighten scenes, previously visible in the EOTF curve analysis, has been partially corrected. Of course, this is within the limits of what the design allows without local dimming – one cannot speak of perfect brightness management here. Nevertheless, the final effect was definitely closer to what one might expect from a mode called Filmmaker.

Digital Image Processing in the S90F:

Fortunately, Samsung, as in most of its models, effectively manages the unwanted posterisation effect in the S90F. The feature responsible for this aspect is noise reduction, which does a decent job of smoothing tonal transitions and eliminating unnatural colour connections – of course, within its limitations. Unfortunately, it operates rather aggressively, so using it comes with compromises. In addition to improving gradation, it can also remove film grain or gently soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you want to preserve the original texture of the material?

Image Scaling in the S90F:

In this year's model, Samsung implemented its own AI processor – NQ4 Gen3, which does quite well with upscaling. In our test scenes, the television effectively "pulled up" lower quality towards artificial 4K – the image was more pleasant to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing facade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival materials – e.g. a VHS tape of your parents' wedding – you must expect that the lower part of the image may be cut off. The image adaptation function to resolution simply does not work here as it should.

LS03F has been equipped with the NQ4 processor, which is responsible for improving image quality – particularly in lower quality materials. In practice, this works surprisingly well, especially when it comes to older content and recordings with lower resolution. Activating the "noise reduction" function yields noticeable effects. The TV 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 advancement – previously, this function often smoothed everything too much, including details that it shouldn't remove. In this year's model, smoothing still occurs, but in a much more acceptable manner. Textures of materials, skin, and fabric details are no longer subdued as strongly as before – the image retains more naturalness. However, this does not change the fact that film grain is still removed by the TV, which may not appeal to everyone. 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 – for example, from VHS tape recordings or low-resolution video. In such cases, we noticed slight clipping of the image at the edges – so-called overscan. This can lead to a situation where a small part of the image (e.g., subtitles at the bottom edge) gets cut off.

The S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is fluid, clear, and there’s no room for any ghosting or blurring that sometimes plagues cheaper LCDs.

The television is also equipped with motion smoothness settings, allowing you to customise everything to your preference. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to that soap opera effect), or more cinematic, with the classic 24-frame 'choppiness'. The choice is yours; Samsung doesn’t impose anything.

The new feature in The Frame for 2025 is a display with a refresh rate of 144 Hz. Yes – in a television that is mainly associated with displaying works of art, you can now not only watch Van Gogh but also comfortably play on a console or follow dynamic sports events. This is a definite step towards greater versatility. In the case of Samsung films, as usual in models with a display rate of 120 Hz and above, it allows you to adjust motion smoothness according to your preferences. You can set a more cinematic reproduction while maintaining frame rate or opt for full motion smoothing. The range of options is broad, allowing you to tailor the effect to your own taste – whether the viewing experience is meant to resemble classic cinema or a show on a modern theatre screen.

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

When it comes to gaming features – the S90F has absolutely nothing to fault. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find the Game Bar – a practical tool that allows you to quickly glance at picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus also deserves a mention – Samsung's proprietary motion enhancer that is the only one truly functioning sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It is also worth mentioning the HGiG feature, which – much to our slight surprise – works correctly. We're mentioning this because Samsung clearly broke something in one of the last updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes practically impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for updates and information from the manufacturer.

As we mentioned earlier – although The Frame is likely to display images and works of art most of the time, Samsung recognised that a Van Gogh enthusiast could just as easily be an avid gamer. And it must be admitted that The Frame 2025 has almost everything needed to become a full-fledged gaming television.

On board, we find support for ALLM (Automatic Low Latency Mode) and Variable Refresh Rate (VRR) thanks to the implementation of one HDMI 2.1 port. The television handles lower resolutions at higher refresh rates effortlessly and features an advanced Game Bar – already known from other Samsung models – which allows for a quick preview and change of the most important gaming-related settings. For this, it earns extra points from us. The proprietary motion smoother Auto Motion Plus Game is also worth mentioning, which – it is worth emphasising – operates without increasing input lag. Samsung remains the only manufacturer that has managed to implement this feature in a practically invisible manner in terms of delays. The effect? Much better fluidity in games, especially those that struggle to maintain a stable 60 frames per second. This solution can realistically improve the gaming experience in more demanding titles – particularly on consoles, which do not always manage full fluidity, especially in AAA games.

As for the downsides – the lack of Dolby Vision is already considered standard in Samsung televisions, so there is not much to particularly criticise here. However, there is a different issue entirely. In the latest version of the Tizen system, the HGiG option has disappeared. Literally – it is not there. This is a significant hindrance when configuring the console for proper HDR content display in games. It is hard to understand why such a decision was made, but one thing is certain – this should be fixed as soon as possible. We are talking about a brand that has set standards for gaming on televisions for years. If HGiG returns – and we hope it will – The Frame LS03F can confidently aspire to be called a genuine gaming television. Not just as a decoration on the wall, but as equipment that truly provides joy in gaming.
