Our verdict

Sony X85L is a model from 2023 that will continue to be available in the 2024 range from the Japanese manufacturer. Its biggest advantage is the Google TV system. It currently provides the greatest access to applications, so we don’t have to worry about missing any of our favourite apps. The intuitive interface and voice control feature using Google Assistant make daily use of the television convenient and modern. As for picture quality, Sony X85L performs well. Thanks to local dimming (albeit with a very mediocre number of zones), black levels look quite decent. Additionally, its fairly high brightness allows for comfortable TV viewing during the day, even in well-lit rooms. Moreover, the television offers a program recording feature from built-in tuners, which is a great convenience for those wanting to control what and when they watch. In terms of motion smoothness, X85L also does not disappoint. The 120 Hz panel and Motionflow system provide smooth display of dynamic scenes, which will satisfy both movie lovers 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 flaws. The lack of HGiG support and high input lag in Dolby Vision mode may be disappointing for more demanding gamers. Additionally, the compromise between font readability and smoothness of the image when connected to a PC may not appeal to everyone. Nevertheless, Sony X85L is a decent piece of equipment that is particularly worth considering if it can be purchased on sale.

It’s time to gather all observations. The TCL P7K / P79K is a television that smartly juggles compromises, offering significantly more in its price range than one might expect. Its undeniable advantage is the VA panel, which guarantees deep blacks and high contrast, while an impressively rich package for gamers (with VRR and support for 120 Hz at lower resolutions) makes it a phenomenal choice for console owners. The whole thing is tied together by a functional Google TV system. Of course, the low peak brightness means that HDR content lacks spectacular highlights, and the TV's performance in sunlit rooms is limited. And while, 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 extra fee, we get a device that is a class above – with a native 4K 144 Hz panel, significantly better audio system, and generally higher operational quality, 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 offers quite decent contrast on its own. Additionally, this model features local dimming technology – in the 55-inch version, it includes 24 zones. Although this number isn’t impressive, it naturally increases with the size of the television. The contrast in the X85L is good, though not the best, especially compared to other televisions also equipped with advanced local dimming technology. Results at a level of 8000:1 are satisfactory, but they average out against the competition. In some cases, such as the third scene from the movie Arrival, the contrast is promising and performs quite well. This is thanks to the very good dimming algorithm that Sony has been using in its televisions for years. Unfortunately, due to the limited number of local dimming zones, the television struggles with noticeable blooming, which can be seen in scenes with the helicopter from the movie Sicario 2.

In discussions about image quality, the conversation almost always begins with the issue of black depth and contrast, which are parameters defining the plasticity and realism of the viewed world. And here, the TCL P7k/P79k immediately lays its strongest advantage on the table – a VA-type panel. It is its construction that ensures the native relationship between the brightest and darkest parts of the image is more than satisfactory, especially in the context of the price segment this model represents. In the majority of scenes, the achieved black has a noble depth, which allows for building an engaging spectacle for the viewer. To illustrate the scale, it's worth mentioning that competing constructions based on IPS panels often offer results that are even four or sometimes five times lower, which constitutes a chasm in direct comparison. Of course, as we venture into the territory of budget-oriented models, we must be aware of certain compromises. Thus, in the discussed television, we will not find an advanced local dimming system that could further enhance the impression of contrast. The absence of this feature is, however, fully understandable and constitutes a logical consequence of the product's positioning 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 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.

When it comes to assessing HDR performance, we need to be clear and straightforward without any marketing fluff: the P7K/P79K is not and never was meant to be a champion in this area. The maximum peak brightness that this panel can generate hovers around just 300 nits. This represents a threshold, a sort of thin red line between what can be considered barely satisfactory HDR signal and what is, in reality, only slightly better than standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests confirmed this harsh reality – our measurements taken during movie sessions showed that the luminance in key bright scenes rarely exceeded 200-250 nits. Therefore, this is not a TV that would allow content created in a wide tonal range to truly shine, and that must be openly acknowledged.

Unfortunately, the issue of colour reproduction is presented just as conservatively. Although the manufacturer positions this model within the "QLED" family, owing 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%. Compared to the market, this is at best an average result, since most devices that utilise additional layers to expand the colour spectrum easily achieve values at a minimum of 90-92%.

After calibration

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.

Every reliable assessment of image quality must start with selecting the most optimal, factory preset mode. In the case of the tested P7K/P79K model, the choice was made without hesitation for the "Film" mode. It is the mode that presents an image closest to the intentions of its 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 is not without a few stumbles. The most noticeable shortcoming turned out to be the not entirely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, frosty character, straying from the ideal neutrality that the director intended to show us. The television handles the reproduction of greyscale in the standard dynamic range much better – the gamma curve is almost exemplary. The only slight reservation can be made for the darkest parts of the image, where a delicate deviation from the norm causes a loss of some detail in the shadows. The most significant challenge, however, for the TCL software was interpreting the HDR signal, as illustrated by the EOTF curve. The television follows its own, rather free path here – the darkest details are disproportionately brightened, followed by a noticeable slowdown in brightness increase for mid-tones. Fortunately, most of these imperfections are of a software nature, which can be eliminated. With that thought in mind, we proceeded to the process of professional calibration.

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.

The calibration process turned out to be spot on, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the tendency of the television to showcase cool tones, restoring white to its natural neutrality. Moreover, the precise adjustment allowed us to correct a slight error in the gamma curve, enabling the darkest parts of the image to regain proper depth, without any signs of unnatural brightness. The results are measurable and impressive – in the ColorChecker test, the vast majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of below 2. This is a result that more expensive models would not be ashamed of. Unfortunately, in the case of HDR content, we encounter a wall in the form of the panel's structural limitations. And although we managed to bring the colours into line, the software's specifics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. To summarise, calibration adds tremendous value, but it is important to be aware that it won't overcome certain physical barriers. The slightly elevated blacks, resulting from the lack of local dimming, and limited peak brightness mean that HDR content won't always be able to showcase its full potential. This is simply not the main task of this display; its true strength, especially after professional tuning, lies in viewing SDR material.

The fluidity of tonal transitions in Sony X85L is at a good level – the colour gradation is smooth, even in more demanding areas, making the perception of scenes positive and natural. The biggest issues arise in shadow areas, where subtle colour joins can 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 assess solely its ability to render smooth colour gradients, we would undoubtedly award it a solid score of 8/10. Unfortunately, this entire positive image is disrupted by the use of very aggressive and visually unpleasant dithering. This artifact is particularly noticeable on demanding test screens – such as the one depicting an actor submerged in red water – where rough, unnatural textures appear on uniform colour planes, revealing the digital nature of the image. This is particularly disappointing as it is not a new problem. It seems to be a sort of hangover from previous generations of budget TCL models, which is a shame, as it marred 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 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.

After a series of harsh evaluations, thankfully, it’s time for some praise, and this is deserved by 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 models; nonetheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The function that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, for instance, from choose.tv. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which means the task of raising low-resolution materials to 4K standard. The resulting image, although it may seem a bit too sharp out of the box, is fortunately not a problem. The software allows for free adjustment of this parameter using a sharpness slider, allowing the final appearance to be easily tailored 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 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.

The issue of fluidity and sharpness of motion image is inextricably linked to the fundamental parameter of the panel, and in the case of the TCL P7K/P79K, we are dealing with a panel that has a native refresh rate of 60 Hz. This specification at the outset defines its capabilities and makes it hard to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During quick camera movements, the image loses sharpness, and the panel also shows a slight tendency to smudge, 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 materials recorded at 24 or 30 frames per second. Thanks to a dedicated slider, the user can decide on the final nature of the motion – from maintaining a fully cinematic, slightly jerky image, to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows one to adjust the viewing experience to their own preferences.

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.

Although on paper the native 4K@60Hz matrix might suggest that the TCL P7K/P79K is not a TV tailored for gamers, the reality turns out to be surprisingly different. On the contrary, the manufacturer has ensured a rich set 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 rounded off with 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 TV effortlessly supports a high refresh rate signal of 120Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know how rarely games run in native 4K at a full 120 frames per second. The option to choose between higher resolution and doubled smoothness is therefore an incredibly sensible compromise.

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

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, particularly when using HDMI 2.1 and playing at 4K resolution 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 high as 95 ms. Such a high level of latency makes the Dolby Vision mode practically unplayable, as responses to commands are noticeably delayed.

Completing 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 can boast an excellent result of just 15 ms. However, the real magic happens when switching to 120 Hz mode, where the lag drops almost by half, reaching values below 10 ms. Such responsiveness ensures that every command from the controller is transmitted 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 involves a bit of balancing between image quality and user comfort. If we want to use the TV for work, where clear fonts matter, we need to set the refresh rate to 60 Hz. In this mode, text looks good and doesn't strain the eyes, which is crucial if we plan to spend a longer time in front of the screen.

On the other hand, if the TV is intended for gaming, where we can take full advantage of its capabilities at 120 Hz, we must consider that the readability of the fonts noticeably decreases. The image becomes less sharp and the text harder to read, which can be frustrating. In short – Sony X85L works well for occasional connection to the computer, but if we need it daily for work and gaming, this compromise may not appeal to everyone.

We finally arrive at the area that can undoubtedly be described as the biggest achilles heel of the TCL P7K/P79K – its compatibility with a PC. This is paradoxical because on paper, everything looks promising. The presence of G-Sync and support for high refresh rates at lower resolutions could suggest that it will also be a great monitor. Unfortunately, practice brutally verifies these assumptions. The key problem is the lack of support for full 4:4:4 chroma sampling. In everyday use, this translates to terrible font rendering quality – they, especially coloured ones, become jagged, surrounded by artifacts, and simply poorly readable. And that’s not all, as in PC mode, the problem of aggressive dithering also becomes apparent, giving the whole image an artificial, overly digital look. The only consolation in this situation is the fact that in games we can take advantage of the extra hertz and G-Sync technology, but these are not advantages that could compensate for the fundamental shortcomings in displaying a static interface. The verdict is therefore clear: while it may still hold up as a screen solely for gaming with a PC, in the role of a monitor for work or browsing the internet, the P7K/P79K simply performs poorly.

Viewing angles on the Sony X85L, as is often the case with VA panels, are not the best. The picture looks great when you’re watching the TV head-on, but all it takes is a slight shift to the side to notice that the colours lose their vibrancy and the contrast noticeably weakens. This could be a problem if the TV is meant for watching in larger groups, where viewers are seated at different angles. For those who typically watch solo or from one central spot, it won't be a major downside, but the picture quality unfortunately drops when watching from the side.

Moving on to the issue of viewing angles, we enter a realm where VA matrix technology dictates unavoidable conditions. As expected, this is the weak point of this model. It is enough to step away from the screen axis to observe a gradual degradation of the image: colours begin to fade, contrast noticeably drops, and blacks lose their depth. In direct confrontation with IPS panels, which are renowned for their generosity in this aspect, the VA matrix must concede superiority to its competitor. Is there a silver lining? Paradoxically, yes. Weak viewing angles are indeed the price we consciously pay for the fundamental advantage of this technology – a significantly higher native contrast and deeper blacks viewed head-on. Thus, we can say that this is a television that favours the viewer sitting in the “ideal” spot, offering them a maximally vivid image at the cost of universality.

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

The last practical test for any television is its daily performance in daylight conditions when it must compete with ambient light. In this competition, the TCL P7K / P79K starts with a certain advantage due to its satin screen coating. Its structure does quite well at suppressing direct reflections, dispersing them and protecting the image from excessive colour fading or brightening of blacks. However, passive combat against reflections is one side of the coin. The other is the active ability to "punch through" bright surroundings, and here one of the key limitations of this model 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 heavily sunlit lounge. In such conditions, the image may lack punch, and scenes with lower brightness may lose readability.

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

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

The design of the Sony X85L TV, while perhaps not the slimmest, is sturdy and elegant. The metal base with adjustable legs is one of its strong points, allowing for the height and width of the television to be adjusted to fit 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 operational brain of the TCL P7K / P79K is the Google TV system, which in itself is a huge advantage. This platform opens access to an almost endless library of applications from the Play Store, ensuring we won't miss any key streaming service. Integration with other devices is exemplary – Apple device owners will appreciate the seamless cooperation thanks to AirPlay, while users of Windows and Android systems can easily take advantage of screen mirroring features. The Google Assistant also deserves a mention, as it handles voice search in Polish exceptionally well, remaining one of the most effective and convenient solutions of its kind on the market. The operation of the system on the tested model can be described as "above average." The interface is mostly smooth, but during testing, it experienced occasional slowdowns and even sporadic "freezes" that required a moment of patience. Minor hiccups are also noticeable in the translation of some system messages, which can be clumsy – these are merely minor oversights on TCL's part that do not affect overall functionality.

Classic Features

In the age of smart systems, traditional television functions often take a back seat, and this case is no different. 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, also counts as a plus. However, this is essentially where the list of conveniences ends. It's evident that TCL has placed nearly everything on the Google TV card, treating classic features as an absolute minimum. Thus, we won’t find options for recording programs from built-in tuners to a USB drive or the once-popular PiP (Picture-in-Picture) feature. It is therefore a basic package that simply works but offers nothing beyond what is essential.

Sony X85L handles playback of most popular file formats from USB without any issues, which is a big plus for those who often access external content. However, it's worth mentioning a minor drawback – 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 at least a curious case, putting us in quite an unusual situation. On one hand, its engine handles the decoding of most popular video formats, which is of course good news. On the other hand, we encountered a surprising and frustrating issue – the default application has a fundamental problem with correctly displaying Polish diacritic characters in subtitle files. Instead of letters like "ą", "ę" or "ż", empty squares or random, illegible symbols appeared on the screen. Fortunately, thanks to the flexibility of the Google TV system, this problem can be easily circumvented. Installing an alternative, advanced player, such as the tried-and-true VLC or KODI, fully resolves this inconvenience. The situation is strange in that this flaw did not occur in other TCL models we tested earlier. So we are dealing with a clear software oversight, which, hopefully, will be corrected in a future update.

The sound on the Sony X85L is good – it's clear across the entire scale, allowing enjoyment of both dialogue 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 be satisfied with this sound profile, while others might require additional audio equipment to fully experience the 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 adequate, but lacking in audiophile ambitions. The speakers play quite loudly, and dialogues in films and TV shows are conveyed clearly and without distortion, which is crucial for everyday use. However, the audio scene definitely lacks the foundation of low frequencies. This is a direct consequence of the absence of a dedicated subwoofer – an element that in the higher P8K series, took the form of a large Onkyo subwoofer at the back of the cabinet, which contributed to its sound strength. Here, that element is simply missing, making the sound seem flatter and devoid of the depth that creates a cinematic atmosphere. We also noticed a peculiar issue with the software – when attempting to set the maximum volume, the TV automatically reduces it. It's hard to definitively say whether this is a form of protection against distortion or a minor software glitch, but it's a shame, as the power reserves seem to be a bit greater.
