Sony X85L vs Philips MLED920 / MLED910

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.

Philips MLED920 in our measurements in static tests even reached around 900 nits, which is really a solid result for a mid-range model. In practice, this translates to a lot of satisfaction during viewing sessions – in scenes rich in bright light, such as the first, third or fifth test slide, the screen managed to generate about 700 nits, which is sufficient to feel the true "HDR effect." However, it cannot be denied that the limited number of dimming zones and the compromises typical of mini-LEDs in more demanding scenes reveal their nature. In sequences with small light sources – like the moon or a scene from the film Sicario 2 – the television clearly prioritises maintaining deeper blacks at the expense of the brightness of these small elements. For most viewers, this is still a reasonable compromise, as the dark background looks significantly better, though it is important to be aware that the details themselves may not impress with their intensity. There is also a certain sense of dissatisfaction regarding the colours. Although the applied PFS filter (the equivalent of quantum dots known from QLEDs) does its job and the colours appear quite vivid, the coverage of the DCI-P3 palette reaches “only” 90%. In everyday viewing, this will be sufficient, but in extremely colourful productions – like the latest Disney animations – one can notice that some tones are not as vibrant as they could be in other setups.

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.

Like every Philips television we tested, we primarily assessed the MLED920 in Filmmaker mode – this is meant to be the "most honest" mode, designed for films and to faithfully convey the intentions of the creators. Indeed, in terms of colour reproduction, it performs the best among all the modes available on the television, but it is not without flaws. The first thing that catches the eye is the white balance. The image has a slight tendency towards purple-pink tones, which gives it a somewhat unnatural character. An even bigger problem, however, turned out to be what we mentioned earlier – image blooming. Just looking at the gamma or EOTF charts reveals that the line significantly deviates from the norm, dropping below a value of 1.8. In practice, this means "bleeding" of the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds well to calibration, and with a few adjustments, one can significantly improve the viewing experience.

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.

After calibration, we managed to largely tame the white balance – to the extent that the average viewer will not be able to detect distortions in colours. The characteristic pink-purple haze that previously disrupted the naturalness of the image has also disappeared. The colour palette has been organised, and the colours appear more coherent and neutral. The gamma in SDR content post-calibration looks really good – there is no longer any mention of the previous 'bleeding' effect in bright scenes. The image has become more contrasty and devoid of that milkiness which had previously greatly harmed the viewing experience. In the case of HDR content, the improvement is also noticeable, although here it is still evident that the television is going 'its own way'. The EOTF curve cannot be fully shaped, as Philips simply does not offer the tools to allow precise control over this parameter in its settings. In many films, the television still exposes the image 'in its own way'. Despite these limitations, the calibration has delivered quite a bit of good – most of the colour distortions have been minimised, and the overall balance of the image has significantly improved. However, it must be noted that certain barriers stem from the very design of the hardware and simply cannot be overcome.

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 manufacturer has equipped this model with several features that improve signal quality, and although we usually approach such "enhancements" with caution, here they prove to be really helpful. The key option is called "distortion reduction" – it works best at a medium level, as on one hand it effectively smooths out unwanted stair-stepping and colour banding, while on the other it does not excessively cut out details, allowing the image to still look natural.

Things are a bit worse with upscaling. Lower quality materials – such as the test video with the model – appeared soft and lacking in sharpness. Indeed, it can be partially corrected with the sharpness slider in the menu, but the effect remains far from what competitors in a similar price range offer. Philips therefore still needs to work on this element, as compared to the successful improvement of tonal transitions, the upscaling simply falls short.

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 Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn't complain about motion smoothness. And indeed – the motion blur is relatively low for a VA panel, and although slight issues can sometimes be noticed on darker backgrounds, they are not something that would stand out to most people during regular viewing.

Another significant advantage is the presence of a motion smoother called “Motion Style.” It allows you to adjust the sensation of smoothness to your own preferences – if someone prefers a more “theatrical,” almost television-like image, they can increase the sliders, whereas if they prefer to maintain the natural “jumps” of cinematic frames, it’s enough to set lower values. This way, everyone can find their golden mean.

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.

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that is considered standard in televisions designed for consoles and PCs today. It features ALLM, so the console automatically switches the screen to game mode, alongside VRR and a refresh rate of 144 Hz, which guarantees smooth gameplay even in fast-paced titles. All key HDR formats are supported – including HGiG and Dolby Vision Gaming for Xbox – which means that regardless of what you are playing and on which console, the television will be able to extract the maximum potential from the image. The Game Bar also proves useful in daily gaming – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, enable VRR or adjust settings without leaving the game. It may not be as comprehensive as the competition, but it performs its task flawlessly. And finally, something that sets Philips apart from the competition – Ambilight. The three-sided LED backlighting can create a huge impression in games, especially in the evening. It's also a way to slightly 'extend' the screen and enhance the feeling of immersion. And as colourful LEDs have recently become almost a mandatory element of a gamer’s room, the MLED920 fits into this trend perfectly.
