Our verdict

Sony X85L is a model from 2023 that will be continued in the offering for 2024 by the Japanese manufacturer. Its greatest advantage is the Google TV system. It currently provides the largest access to applications, so we need not worry that one of our favourite applications will be missing. The intuitive interface and voice control feature using Google Assistant make daily use of the television comfortable and modern. As for picture quality, Sony X85L performs well. Thanks to local dimming (albeit with a very average number of zones), black levels look quite decent. Additionally, its fairly high brightness allows for comfortable television viewing during the day, even in well-lit rooms. Furthermore, the television offers a programme recording function with built-in tuners, which is a great convenience for those wanting to control what and when they watch. In terms of motion smoothness, X85L does not disappoint either. The 120 Hz panel and Motionflow system ensure smooth display of dynamic scenes, satisfying both movie enthusiasts and sports fans. The television is also equipped with a range of features for gamers, including VRR, Game Bar and G-Sync support, making it an attractive choice for gaming enthusiasts. Of course, the television is not without its faults. The lack of HGiG support and high input lag in Dolby Vision mode can be disappointing for more demanding gamers. Additionally, the compromise between font readability and image smoothness when connected to a PC may not appeal to everyone. Nevertheless, Sony X85L is a decent piece of equipment that is particularly worth attention if it can be purchased on promotion.

The time has come to gather all observations. The TCL P7K / P79K is a television that cleverly juggles compromises, offering much more in its price range than we could have expected. Its undeniable asset is the VA panel, guaranteeing deep blacks and high contrast, and the surprisingly rich package for gamers (with VRR and support for 120 Hz at lower resolutions) makes it a phenomenal proposition for console owners. The whole is tied together by the functional Google TV system. Of course, the low peak brightness means that HDR content lacks spectacular bursts, and the TV's performance in sunlit rooms is limited. And although, at its relatively low price, the P7K / P79K is quite a decent option, its biggest rival turns out to be… its more refined sibling, the P8K. Often, FOR a small additional payment, we get a device of a higher class – with a native 4K 144 Hz panel, significantly better audio system, and generally higher quality of operation, which is reflected in its much higher rating on our portal. Therefore, the final verdict must be as follows: if your budget is absolutely non-negotiable, the P7K / P79K will be a good and cost-effective choice. However, if you can afford to add a small amount, the P8K model will offer significantly more and will ultimately be a more satisfying investment.

The Sony X85L television is equipped with a VA panel, which in itself offers quite good contrast. Additionally, this model features local dimming technology – in the 55-inch version, it encompasses 24 zones. Although this number is not impressive, it naturally increases with the size of the television. The contrast in the X85L is good, though not the best, especially in comparison to other televisions also equipped with advanced local dimming technology. Results at a level of 8000:1 are satisfactory, but appear average in the context of competition. In some cases, such as the third scene from the film Arrival, the contrast is promising and performs fairly well. This is thanks to the very good dimming algorithm that Sony has employed in its televisions for years. Unfortunately, due to the limited number of local dimming zones, the television struggles with noticeable blooming, which can be observed, for example, in scenes with the helicopter from the film Sicario 2.

In the discussion about image quality, the conversation almost always begins with the issue of black depth and contrast, which are parameters that define the plasticity and realism of the observed world. Here, the TCL P7k/P79k immediately lays its strongest asset on the table – a VA panel. Its construction is what makes the native relation between the brightest and darkest parts of the image more than satisfactory, especially in the context of the price segment that this model represents. In the majority of scenes, the black achieved has a noble depth, which allows for building an engaging spectacle for the viewer. To illustrate the scale, it is worth mentioning that competing constructions based on IPS panels often offer results that are even four times, and sometimes five times, lower, which in direct comparison represents a chasm. Of course, when entering the territory of models oriented towards affordability, we must be aware of certain compromises. Therefore, we will not find an advanced local dimming system in the discussed television, which could further enhance the sense of contrast. However, the absence of this feature is fully understandable and constitutes a logical consequence of positioning the product in the market – this technology in TCL's portfolio for 2025 has been reserved for higher positioned, more prestigious series marked with the letter "C".

HDR luminance

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.

When turning to the assessment of HDR performance, we must be clear and without marketing embellishments: the P7K/P79K is not, and was never intended to be, a master in this field. The maximum peak brightness that this panel can generate hovers around a mere 300 nits. This represents a threshold, a kind of thin red line between what can be considered a barely satisfactory HDR signal and what is, in fact, not much different from standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests found brutal confirmation in reality – our measurements taken during movie screenings showed that luminance in key bright portions of the scenes rarely exceeded the ceiling of 200-250 nits. Thus, this is not a television that would allow content realised in a wide tonal range to spread its wings, and this must be openly admitted.

Unfortunately, the issue of colour reproduction is presented with equal restraint. Although the manufacturer positions this model within the "QLED" family, thanks to the use of a PFS LED filter, the results do not match the heightened expectations. The coverage of the wide DCI-P3 colour gamut reaches only 86%. In the context of the market, this is at best an average result, as most devices that employ additional layers to expand the colour spectrum easily achieve values at a minimum level of 90-92%.

After calibration

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.

Every accurate assessment of image quality must begin with selection of the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was made without hesitation for the "Film" mode. It is this mode that presents an image closest to the intentions of the creators, avoiding both the exaggerated brightness of the dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it has not escaped a few missteps. The most noticeable flaw turned out to be the not completely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, cold character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the greyscale in the standard dynamic range – the gamma curve is nearly exemplary. The only minor reservation could be made regarding the darkest parts of the image, where a slight deviation from the norm causes a loss of some detail in the shadows. The most serious challenge for the TCL software, however, was interpreting the HDR signal, as illustrated by the course of the EOTF curve. The television follows its own, quite free path here – the darkest details are disproportionately brightened, after which there is a noticeable slowdown in the increase of brightness for midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we began the process of professional calibration.

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.

The calibration process turned out to be spot on, particularly in the context of standard dynamic range (SDR) content. We successfully mitigated the television's tendency to emphasize cool tones, restoring the whiteness to its natural neutrality. Moreover, precise adjustments allowed us to correct a slight error in the gamma curve, ensuring that the darkest parts of the image regained their proper depth, without any trace of unnatural brightness. The effects are measurable and impressive – in the ColorChecker test, the overwhelming majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of under 2. This is a result that pricier models would not be ashamed of. Unfortunately, when it comes to HDR content, we encounter a barrier in the form of the inherent limitations of the panel itself. And although we managed to bring the colours into line, the software's characteristics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration adds immense value, but one must be aware that it cannot overcome certain physical barriers. The slightly elevated black level, due to the lack of local dimming, along with limited peak brightness, means that HDR content may not always be able to showcase its full potential. This is simply not the primary task of this display; its true strength, especially after professional tuning, lies in the viewing of SDR material.

The fluidity of tonal transitions in Sony X85L is at a good level – the gradation of colours is smooth, even in more demanding areas, which makes the perception of scenes positive and natural. The biggest issues arise around shadows, where subtle colour joins may be visible. Despite this, the television performs well enough that most viewers should not notice these minor imperfections.

The issue of the fluidity of tonal transitions, or popular grading, is another area where the P7K / P79K evokes mixed feelings and surprises with its dual nature. If we were to evaluate solely its ability to render smooth colour gradients, we would undoubtedly give it a solid score of 8/10. Unfortunately, this positive image is marred by the use of very aggressive and unpleasant dithering. This artefact is particularly noticeable on demanding test patterns – such as the one depicting an actor submerged in red water – where rough, unnatural texture appears on uniform colour surfaces, betraying the digital nature of the image. This is all the more disappointing, as it is not a new issue. It seems to be a sort of inheritance from previous generations of budget TCL models, which is a pity, as it represents a flaw on what is fundamentally a quite competent image and is a mistake that could have been avoided.

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.

After a series of harsh evaluations, fortunately, the time comes for praise, and this is due to the TCL AiPQ image processor for its work in the field of digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; however, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature for smoothing tonal transitions performs particularly well, effectively eliminating posterisation, which are the characteristic bands often visible in highly compressed materials, for example, from the ChooseTV service. The algorithm adeptly removes unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which is the task of elevating low-resolution materials to 4K standard. The resulting image, although it may initially seem a bit too sharp, fortunately, is not a problem. The software allows for free adjustment of this parameter using a sharpness slider, making it easy to customise the final appearance to personal preferences.

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 issue of fluidity and sharpness of the image in motion is inextricably linked to a fundamental parameter of the matrix, and in the case of the TCL P7K/P79K, we are dealing with a panel with a native refresh rate of 60 Hz. This specification defines its capabilities from the outset and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During fast camera movements, the image loses sharpness, and the panel also shows a slight tendency to smearing, which may be noticeable to more sensitive viewers. Fortunately, not everything in this aspect has been left to chance. The manufacturer has implemented a simple motion smoothing system, which is primarily used in film material recorded at 24 or 30 frames per second. Thanks to a dedicated slider, users can decide for themselves the final character of the motion – from maintaining a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple but effective tool that allows users to tailor the viewing experience to their own preferences.

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.

Although on paper the native 4K@60Hz panel might suggest that the TCL P7K/P79K is not a television tailored for gamers, the reality is surprisingly different. On the contrary, the manufacturer has ensured a rich package of features that make it a very friendly companion for next-generation consoles. Onboard, we find key technologies such as ALLM, which provides automatic switching to low latency mode, and VRR, or variable refresh rate, which eliminates screen tearing. The list is complemented by support for Dolby Vision Gaming and a simple yet functional Game Bar. However, the real and extremely pleasant surprise is something else. It turns out that the television easily supports a high refresh rate signal of 120 Hz but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know well how rarely games run in native 4K at a full 120 frames per second. The ability to choose between higher resolution and doubled smoothness is therefore an extremely sensible compromise.

In summary, although the P7K/P79K may not be the target screen for the most passionate tournament players, for the casual or occasional console user, it offers a package of options that is hard to find among many competitors at this price.

Generally speaking, the input lag on the Sony X85L is very good, which is crucial for smooth gameplay and quick reactions in games. In standard modes, especially when using HDMI 2.1 and playing at a resolution of 4K at 120 Hz, the input lag is minimal.

Unfortunately, the Dolby Vision mode is an exception to this rule. In this case, the input lag reaches as much as 95 ms. Such a high level of delay makes the Dolby Vision mode virtually unplayable, as the responses to commands are noticeably delayed.

Complementing this rich package for gamers is a parameter that has a direct impact on comfort and performance in gameplay – input lag. Already in native 60 Hz mode, the television boasts an excellent result of just 15 ms. However, the real magic happens when switching to 120 Hz mode, where the lag drops nearly by half, reaching values below 10 ms. Such responsiveness ensures that every command from the controller is translated to the screen in the blink of an eye, which will be appreciated not only by professionals but by anyone who values smooth and direct interaction with the game.

Review Sony X85L Compatibility with PC
Review TCL P7K / P79K Compatibility with PC

The collaboration of the television Sony X85L with a PC is a bit of a balance between image quality and user comfort. If we want to use the television for work, where clear fonts matter, we need to set the refresh rate to 60 Hz. In this mode, the text looks good and doesn't strain the eyes, which is crucial if we intend to spend a longer time in front of the screen.

On the other hand, if the television is to be used for gaming, where we can take full advantage of its capabilities at 120 Hz, we must bear in mind that the readability of fonts noticeably decreases. The image becomes less sharp, and the text harder to read, which can be frustrating. In short – Sony X85L will perform well for occasional connections to a computer, but if we need it on a daily basis for work and gaming, this compromise may not appeal to everyone.

We finally come to an area that can undoubtedly be described as the biggest Achilles' heel of the TCL P7K/P79K – its compatibility with PC. It is paradoxical in that, on paper, everything looks promising. The presence of G-Sync and support for high refresh rates at lower resolutions might suggest that it would also be a great monitor. Unfortunately, practice brutally verifies these assumptions. The key issue is the lack of support for full 4:4:4 chroma sampling. In everyday use, this translates to terrible font rendering quality – these, especially the coloured ones, become jagged, surrounded by artefacts, and simply poorly legible. This is not the end of the story, as in PC mode, the problem of aggressive dithering also becomes evident, giving the entire image an artificial, overly digital appearance. The only consolation in this situation is the fact that in games we can take advantage of the additional hertz and G-Sync technology, but these are not advantages that could compensate for the fundamental deficiencies in displaying a static interface. The verdict is therefore clear: while as a screen solely for gaming on PC it might still hold its own, as a monitor for work or browsing the internet, the P7K/P79K simply performs poorly.

The viewing angles on the Sony X85L, as is often the case with VA panels, are not the best. The picture looks great when viewed directly, but as soon as you move to the side, you notice that the colours lose intensity and the contrast significantly weakens. This can be an issue if the television is meant for viewing in larger groups, where viewers are seated at different angles. For those who usually watch solo or from one central spot, this won’t be a major downside, but when watching from the side, the picture quality unfortunately declines.

When it comes to viewing angles, we enter the territory where VA panel technology dictates unavoidable conditions. As expected, this is the weak point of this model. It is enough to move away from the screen axis to observe a gradual degradation of the image: colours begin to fade, contrast noticeably drops, and black loses its depth. In direct comparison with IPS panels, which are renowned for their generosity in this aspect, the VA panel must concede superiority to its competitor. Is there any upside to this? Paradoxically, yes. Poor viewing angles are, after all, the price we consciously pay for the fundamental advantage of this technology – a significantly higher native contrast and deeper blacks when viewed head-on. Thus, it can be said that this is a television that favours viewers sitting in the 'ideal' spot, offering them a maximally vibrant image at the cost of versatility.

The performance of the television Sony X85L during the day is quite decent. Its satin screen coating handles light reflection moderately well, meaning that in bright rooms there can be some glare, but it is not bothersome enough to significantly interfere. The brightness in SDR mode at 570 nits is sufficient for comfortable TV viewing during the day, even with natural light coming in through the windows. This ensures that colours remain vivid and the picture is clearly visible, making the television suitable for everyday use.

The final practical test for any television is its daily performance in daytime conditions when it has to compete with ambient light. In this competition, the TCL P7K / P79K starts with a certain advantage in the form of a satin finish on the screen. Its structure handles direct reflections quite decently, diffusing them and protecting the image from excessive fading of colours or lightening of blacks. However, the passive struggle against reflections is one side of the coin. The other is the active ability to 'break through' bright surroundings, and here one of the model's key limitations comes to light. The previously mentioned peak brightness of around 300 nits is simply too low to ensure a fully comfortable and dynamic viewing experience in a brightly lit living room. In such conditions, the image may lack punch, and scenes with lower brightness can lose their clarity.

Sony X85L runs on the Google TV system, which is a substantial advantage for many users. The television offers wide access to applications, and using streaming platforms is smooth and user-friendly. The interface is intuitive and easy to master, allowing quick switching between applications and searching for favourite content. Google TV allows for personalisation of the home screen, enabling each user to tailor it to their preferences. The Google Assistant further enriches the experience by offering voice control and quick changes to settings or searching for films without the need for a remote.

In terms of user features, Sony X85L offers many useful options. The television has the capability to record programmes, which is a significant convenience for those wanting to watch their favourite content at any time. AirPlay support allows for seamless content streaming from Apple devices, which iPhone and iPad owners will appreciate. Additionally, thanks to the built-in Bluetooth, various devices such as headphones or keyboards can be connected. However, one of the shortcomings is the PiP (picture-in-picture) function, which may disappoint users who prefer multitasking on screen.

The design of the Sony X85L television, while perhaps not among the thinnest, is solid and elegant. The metal stand with adjustable feet is one of its stronger points, allowing the height and width of the television to be adapted to various furniture and spaces. This practical solution enhances the interior and adds a modern character to it.

Smart Features – the Power of Google TV

The heart and operating brain of the TCL P7K / P79K is the Google TV system, which is a significant advantage in itself. This platform opens access to an almost limitless library of applications from the Play Store, ensuring that we won't miss any key streaming service. Integration with other devices is exemplary – Apple users will appreciate the seamless collaboration thanks to AirPlay, and Windows and Android users can easily utilise screen mirroring features. One should also highlight Google Assistant, which performs exceptionally well with voice search in Polish, remaining one of the most effective and convenient solutions of its kind on the market. The system’s performance on the tested model can be described as "above average." The interface is mostly smooth, but during tests, there were occasional slowdowns and even sporadic "freezes" that required a moment of patience. Minor glitches can also be seen in the translation of some system messages, which can be clumsy – however, these are minor oversights on TCL's part that do not affect overall functionality.

Classic Features

In the era of smart systems, traditional television functions often take a back seat, and this is also the case here. A significant advantage is the inclusion of a classic remote control with a numeric keypad, which does not require precise aiming at the screen for communication, significantly enhancing user comfort. The presence of Bluetooth technology for connecting external devices, such as headphones or speakers, should also be regarded positively. However, this is essentially where the list of conveniences ends. It is evident that TCL has almost put everything on the Google TV card, treating classic functions as an absolute minimum. Therefore, we will not find options to record programmes from built-in tuners to a USB drive or the once-popular PiP (Picture-in-Picture) feature. This is, therefore, a basic package that simply works but does not offer anything beyond what is essential.

Sony X85L easily handles playback of most popular file formats from USB, which is a big plus for those who often access external content. However, it should be mentioned that there is a small downside – the built-in player does not allow for changing the font colour in subtitles, which may be troublesome for some. Fortunately, thanks to the extensive Google TV system, users have a wide range of options. Alternative media players can be easily installed, offering more personalisation options.

The built-in media player in the P7k/P79k model is quite a puzzling case, placing us in a rather unusual situation. On one hand, its engine manages to decode most popular video formats, which is obviously good news. On the other hand, we encountered a surprising and frustrating flaw – the default app has a fundamental issue with correctly displaying Polish diacritical characters in subtitle files. Instead of letters like "ą," "ę," or "ż," empty squares or random, unreadable symbols appeared on the screen. Fortunately, thanks to the flexibility of the Google TV system, this issue can be easily circumvented. Installing an alternative, advanced player, such as the tried and tested VLC or KODI, fully resolves this inconvenience. The situation is particularly odd since we didn't encounter such a flaw in other TCL models we tested previously. We are therefore dealing with an obvious software oversight, which we hope will be fixed in a future update.

The sound in Sony X85L is good – it is clear across the entire range, allowing enjoyment of both dialogues and music. The bass, though light, is noticeable and adds some depth to the overall sound. However, it should be emphasised that this is a subjective assessment – some may find such a sound profile satisfying, while others might need additional audio equipment to fully experience stronger tones and a more spacious sound.

In terms of the built-in audio system, the TCL P7k/P79k presents a level that can be described as functional and correct, but lacking audiophile ambitions. The speakers play quite loudly, and the dialogues in films and television programmes are delivered clearly and without distortion, which is crucial in everyday use. However, the soundstage definitely lacks a foundation in the form of low tones. This is a direct consequence of the absence of a dedicated subwoofer – an element that in the higher P8K series, represented by a large Onkyo subwoofer at the back of the cabinet, constituted the strength of its sound. Here, that element is simply missing, which makes the sound seem flatter and devoid of the depth that creates a cinematic atmosphere. We also noticed a peculiar aspect in the software – when attempting to set the maximum volume, the television automatically reduces it. It is difficult to determine definitively whether this is a form of protection against distortion or a minor software glitch; nonetheless, it’s a shame because the power reserves seem to be slightly greater.
