Sony X85L vs Samsung S85F OLED

The Sony X85L television offers solid HDR performance with a brightness level of 750 nits, which is sufficient to enjoy vivid effects. In scenes of moderate difficulty, such as the first, third, or fifth test scenes, a brightness of around 600 nits allows one to fully experience the HDR effect. Unfortunately, in more demanding segments, like the scene from the film Sicario 2, the television reveals its limitations. Drops in brightness to 250 nits cause the HDR effect to lose its impressive quality, resembling rather ordinary SDR. Nevertheless, it is worth highlighting the very good coverage of the DCI-P3 colour palette at 95%, which definitely deserves praise and positively impacts the overall image quality.

For an OLED, the Samsung S85F can truly shine – literally. Under favourable conditions, it is capable of generating brightness exceeding 750 nits. This is hugely significant, as most films are created with displays reaching around 1000 nits in mind. In practice, this means that in scenes with moderately large, bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a huge amount of light on the screen – whether it's an expansive, bright background or a whole frame filled with white – the S85F has to tone it down. In such scenes, brightness can drop by even four times. This limitation is well-known to essentially every OLED in this price segment, so we do not consider it a particular shortcoming. However, something that deserves praise and sets this model apart from the competition is its colour gamut coverage. Thanks to the QD-OLED panel, our colourimeter recorded values exceeding 100% DCI-P3 coverage and as much as 86% for the ultra-wide BT.2020 gamut. Such results are hard to find even in televisions costing several times more.

The television Sony X85L was tested in IMAX Enhanced mode, which, although associated with world-class cinema, does not guarantee an image that aligns with the director's intention. The main problem is the white balance – there is a noticeable strong dominance of blue colour and significant shortcomings in red. As a result, the picture becomes unnaturally cool and looks artificial. Errors in colour reproduction were confirmed by the Colour Checker test, which showed considerable discrepancies – the colours were "scattered" like shots from a rifle, and only a few samples hit the target values. This clearly demonstrates that the accuracy of colour reproduction leaves much to be desired.

The brightness of the image is one of the positive features of the television. The gamma for HD content is at an acceptable level, although there are minor errors, but generally it is quite good. However, the characteristic of brightness for 4K materials remains a problem, controlled by the EOTF curve. It is evident here that very small, bright elements of the image are too dim, which is the result of the limited number of backlighting zones due to the design of the television.

Samsung, as befits a manufacturer with ambitions, has equipped the S85F with a mode called Filmmaker. Its task is simple: to ensure that the colours on the newly purchased television are as true to what the director intended as possible. Sounds great… but, as is often the case, a theory that sounds great does not always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as though someone had overdone the saturation a bit. As a result, quite significant colour errors occurred, particularly in 4K content. Moreover, there was a problem with brightness – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could test what this panel is truly capable of when placed in the right hands.

Thanks to the application of calibration tools offered by Sony X85L, the image quality has been significantly improved. After calibration, the white balance for HD content is much more stable, making colours appear more natural and enhancing the authenticity of the image. Although it is not perfect, these changes allow viewers to enjoy a more realistic colour reproduction, eliminating the previous cool tone. The gamma, which was already decent, has been adjusted to an even better version. As a result, tonal transitions and brightness are more consistent, positively affecting the depth and detail of the image.

As for 4K content, despite efforts, the white balance still struggles with a lack of red, which can lead to overly warm colours in some scenes. Synthetic tests showed that the EOTF curve in HDR is quite stable, with a slight enhancement in mid-bright scenes. However, in actual film material, the television can still be too bright with fine, light details, which is a result of the limitations of large local dimming technology.

Nevertheless, calibration has brought significant benefits, particularly in terms of colour accuracy, improving the overall image quality and providing a more natural and cohesive directorial vision.

Thanks to the vast number of settings in the menu, we managed to bring the S85F to nearly an ideal level. The white balance in SDR content? Literally perfect – deviations do not exceed the value of “1”. So we can confidently say that in materials with not very high dynamics, we have an image close to reference here.

In HDR content, slight issues have arisen, but they are not significant in practice – most errors fall below the threshold of perceptibility, which is the value of “3”. We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in movies, holds an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy films and series at the highest level.

In terms of smoothing tonal transitions, the Sony X85L television does not offer any dedicated enhancement options, which is a certain drawback. On the other hand, the image scaling performs quite well – the television adds a bit of artificial sharpness, which may make details such as tree branches more pronounced, although sometimes with noticeable jagged edges. This type of effect may appeal to some viewers who prefer a more detailed image.

The tonal transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality materials, such as those from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out the film grain that many of us consider a key element of the cinematic experience. At the "Standard" level, we did not notice that this function removed anything significant from the image, so we can recommend this setting. On the other hand, the "High" level is a different story – it can smooth out not only noise but also subtle, desirable details such as the texture of objects.

As for image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible aliasing of contours. And there’s still the persistent issue with Samsung televisions – overscan. This can cause the frame to be slightly cropped in certain scenes, which is worth keeping in mind when watching very old content.

Sony X85L, equipped with a 120 Hz panel, will meet the expectations of a wide range of users – from sports and gaming fans to movie enthusiasts. Movie buffs will certainly appreciate the presence of one of the best motion smoothing systems, known as Motionflow. This system offers adjustment through sliders for smoothness and clarity – smoothness is responsible for motion fluidity, eliminating judder, while clarity improves the sharpness of fast scenes, reducing blur.

The S85F is a mind-blowingly fast television – and this is not just an empty phrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is “slipping away” from the frame. The lightning-fast pixel response time, typical of OLEDs, plays its part here. Transitions between frames are virtually instantaneous, and the picture remains clear even during the fastest camera movements. A ball flying across half the pitch? A car racing in a chase scene? Here, everything is clear and free from the characteristic “trail” of LCDs.

This is exactly what we expect from a good OLED – no compromises when it comes to motion fluidity. The S85F gives the impression that regardless of the pace of the action, we can focus on what is happening on the screen, rather than the imperfections of the image.

Sony X85L offers a quite solid set of features for gamers, making it an attractive choice for gaming enthusiasts. First and foremost, the television has a 120 Hz panel, which translates to smooth and dynamic image display, ideal for both fast-paced action games and more demanding sports titles. It is equipped with two HDMI 2.1 ports with full bandwidth of 48 Gb/s, allowing for the full utilisation of next-generation consoles. Additionally, Sony X85L supports VRR (Variable Refresh Rate) technology, which helps reduce stuttering and artifacts during gameplay, providing a smooth experience. The television also supports G-Sync, which is particularly beneficial for gamers using NVIDIA graphics cards, allowing for the synchronisation of the screen refresh rate with GPU performance, eliminating screen tearing. It is worth mentioning the Game Bar feature, which facilitates quick access to the most important gaming-related settings, such as VRR, brightness levels, and display modes, which is convenient and useful during gameplay.

However, there are certain limitations. The television does not support HGiG, which may be a downside for some gamers, as HGiG optimises HDR effect rendering in games, providing a more authentic visual experience. Additionally, while the Dolby Vision mode is available, it is not practical for gaming due to the very high input lag.

The S85F has practically everything on board to become the dream screen for gaming. Four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – and on top of that, a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag only increases slightly. This is a rare combination, and it’s a big plus for Samsung.

Now comes the moment when we need to complain a little. The lack of Dolby Vision in Samsung televisions has become standard, so there’s no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, in accordance with the creators' intentions. Without it, HDR calibration on a console becomes less precise, so we can end up with an image that is too dark in the shadows or excessively overexposed.

Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect television for gamers.
