Sony X85L vs Samsung S85F OLED

The Sony X85L TV offers solid HDR performance with a brightness of 750 nits, which is sufficient to enjoy vibrant effects. In scenes of moderate difficulty, such as the first, third, or fifth test scenes, a brightness of around 600 nits allows you to fully experience the HDR effect. Unfortunately, in more demanding segments, like the scene from the film Sicario 2, the TV reveals its limitations. Drops in brightness to 250 nits make the HDR effect lose its impressive quality and resemble ordinary SDR. Nonetheless, 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.

As an OLED, the Samsung S85F can shine – literally. In favourable conditions, it can generate brightness exceeding 750 nits. This is significant because most films are created with displays aiming for around 1000 nits. In practice, this means that in scenes with moderately large, bright elements, the picture can look absolutely stunning. However, it's not always so rosy. When an enormous amount of light appears on the screen – whether it's an expansive, bright background or an entire frame filled with white – the S85F must tone it down. Brightness can drop by even four times in such scenes. This limitation is well-known to anyone familiar with OLEDs in this price segment, so we don't view it as a particular fail. However, something that deserves praise is what sets this model apart from the competition – colour gamut coverage. Thanks to the QD-OLED panel, our colour meter indicated values exceeding 100% coverage of DCI-P3 and an impressive 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

The television Sony X85L has been tested in IMAX Enhanced mode, which, while associated with world-class cinema, does not guarantee an image consistent with the director's intent. The main issue is the white balance – there is a noticeable strong dominance of blue and significant deficiencies in red. As a result, the image becomes unnaturally cool and looks artificial. Errors in colour reproduction were confirmed by the Colour Checker test, which showed significant discrepancies – colours were "scattered" like shots from a rifle, and only a few samples hit the target values. This clearly shows that the precision 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 minor errors occur, but generally it is quite good. However, the issue remains the brightness characteristic for 4K materials, 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 backlight 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 make the colours on the newly purchased television as faithful as possible to what the director intended to show us. Sounds great… but, as is often the case, a theory that sounds wonderful doesn’t 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 if someone had gone a bit overboard with the saturation. As a result, there were quite significant colour errors, particularly in 4K content. On top of that, there was an issue with brightness – the S85F could brighten most scenes more than it should, stripping them of the intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means that we could see what this panel is really capable of when it gets into the right hands.

Thanks to the use of calibration tools offered by Sony X85L, it has been possible to significantly improve the image quality. After calibration, the white balance for HD content is much more stable, making colours look more natural and enhancing the authenticity of the image. Although it's not perfect, these changes allow viewers to enjoy a more realistic representation of colours, eliminating the earlier cool tone. The gamma, which already performed reasonably well, has been adjusted to an even better version. As a result, tonal transitions and brightness are more consistent, positively impacting 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 cause overly warm colours in some scenes. Synthetic tests showed that the EOTF curve in HDR is fairly stable, with a slight boost in mid-bright scenes. However, in actual film material, the TV can still be too bright with fine, light details, which is a result of the limitations of large local dimming technology.

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

Thanks to the huge number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". So we can confidently say that in materials with not too high dynamics, we have an image that's close to reference.

In HDR content, minor issues appeared, but they don't have much significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F when it comes to brightness management – the EOTF curve, even in films, holds nearly perfect straight line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply watch movies and series at the highest level.

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

The tone transition smoothing function in the S85F works really effectively – it can completely eliminate the problem of visible banding in very poor quality material, such as from YouTube. Unfortunately, even the lowest level of this option comes with compromises. The noise reduction is so aggressive that it can smooth out film grain, which many of us consider to be an element of the cinematic atmosphere. At the “Standard” level, we didn’t notice this function removing 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 just noise, but also small, desirable details like, for example, the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only slight imperfection is the barely noticeable aliasing of edges. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to be slightly cropped, which is worth noting 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 lovers will surely appreciate the presence of one of the best motion smoothing systems, known as Motionflow. This system offers adjustment using smoothness and clarity sliders – smoothness is responsible for fluid motion, eliminating the stuttering effect, while clarity enhances the sharpness of fast scenes, reducing blur.

S85F is an incredibly fast television – and that’s not just empty hype. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look just as they should – smooth, sharp, and without the feeling that something is "slipping" out of frame. The lightning-fast pixel response time, typical of OLEDs, plays a big role here. Transitions between frames are virtually instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car speeding in a chase scene? Everything here is clear and free of the typical "trail" associated with LCDs.

This is exactly what we expect from a good OLED – zero compromises when it comes to motion smoothness. The S85F gives the impression that regardless of the pace of action, we can focus on what’s happening on the screen, rather than on the imperfections of the image.

Sony X85L offers a fairly 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 capabilities of next-generation consoles to be utilised. Additionally, Sony X85L supports VRR (variable refresh rate) technology, which helps reduce stuttering and artifacts during gameplay, ensuring a smooth experience. The television also supports G-Sync, which is particularly beneficial for gamers using NVIDIA graphics cards, allowing for screen refresh rate synchronization with GPU performance, eliminating screen tearing. It’s worth mentioning the Game Bar feature, which facilitates quick access to important game-related settings, such as VRR, brightness levels, or display modes, making it convenient and useful during gameplay.

However, there are some 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, the Dolby Vision mode, although available, is not practical for gaming due to very high input lag.

S85F has practically everything on board to become the dream screen for gaming. Four full 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 – plus a gem in the form of Game Motion Plus. This motion smoother makes animation in games more enjoyable, while input lag increases slightly. It's a rare combination, and that’s a big plus for Samsung.

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