Our verdict

Samsung OLED 48 S90D or S94D is the smallest model in this series, and we had the opportunity to see what it can do. At first glance, it's evident that it deals excellently with details in dark scenes, as is expected from an OLED. However, it is worth mentioning that the 48-inch version differs from the larger models. Brightness is slightly lower, and the panel has a satin finish instead of glossy. During the day, this may affect the perceived image. Nevertheless, regardless of the variant, OLED always makes an impression. The depth of black is incredible, and the contrast ensures that even the most demanding scenes look cinematic. When it comes to high-quality materials, the television literally shines here – bright elements in dark frames literally pop out of the screen. The factory colour settings could be better, but after calibration, the television showcases its full potential. While watching from different spots in the room, we noticed that wide viewing angles make a difference – the image remains clear and full of detail, even when viewed from the side. The Tizen system proved convenient to use – applications like Netflix and Prime Video were within easy reach. A few less popular applications were missing, which could be a downside, but it wasn’t a problem for us. The interface itself ran smoothly without any hiccups.  During sports and dynamic movie viewing, the television showed what it’s capable of. The 144 Hz panel eliminates motion blur, and fast actions are displayed smoothly and without interruptions. What is gaming like on this television? It's simply a pure pleasure.  Low input lag and support for 144 Hz made every gaming session responsive and smooth, regardless of whether we were playing fast-paced FPSs or calmer strategy games. Samsung OLED 48' S90D/S94D is a great choice for those looking for a smaller television with excellent picture quality and additional features for gamers. It's not without its compromises, but it performs really well in everyday use. For us, it's a compact piece of equipment that proves that size doesn’t always matter.

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.

Review TCL P7K / P79K Contrast and black detail

Samsung OLED 48 S90D stands out due to its use of OLED technology, which provides an extremely high contrast, one of its key advantages. OLED technology allows each pixel to emit light independently, resulting in perfectly deep blacks and excellent visibility of details even in the darkest scenes. Unlike traditional LCD screens with backlighting, where blacks can appear blurred and greyish due to uneven illumination, OLED ensures that pixels are completely turned off in areas where black should appear. As a result, contrast reaches an impressive level, and images become more vibrant and realistic. An example can be seen in a scene from the film “Oblivion,” where the S90D effectively captures the intense light of the lantern, highlighting the details in the bright areas of the image. In “Sicario 2,” the OLED panel accurately reproduces the helicopter lights against a dark background.

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".

In the tested film scenes, the television Samsung OLED 48 S90D achieves impressive brightness results, surpassing 800 nits in the first four shots, which can be considered a very good result. In the case of the final shot, where a fullscreen flash of sunlight is visible, the brightness drops to around 400 nits, but still remains at an acceptable level. However, it's worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage at 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing image quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating in choosing the size of the S90D model, it is worth mentioning that the larger versions of this television offer better HDR effects, and consequently, higher scores in our tests.

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%.

Factory Mode

After calibration

The S90D Samsung television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode can seem overly warm, and users switching from Standard mode may experience a slight shock. It's worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to become warmer than they should be. In practice, this means that some shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma graph indicates slight fluctuations, causing the image to be minimally darker, especially in shadows. This may affect less distinct details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is situated above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image right out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

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.

After calibration, the television Samsung OLED 48 S90D in film mode looks even better than one could have presumed. The white balance, for both HD and 4K HDR content, has been improved to nearly perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the quality of the image. The colours are more balanced, which translates to a natural representation of details, particularly in scenes requiring a precise colour palette. It is worth adding that this model in the 48' size is equipped with a WOLED panel that has a different characteristic compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering such rich colours as, for example, the 65-inch version, which is fitted with a QD-OLED panel.

The contrast has also undergone significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between the bright and dark parts of the image. The EOTF curve, which before calibration showed issues with overexposed scenes, now displays better results. This effect allows for greater detail preservation in the bright parts of the image, especially in HDR material.

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 on the Samsung OLED 48 S90D television is at a good level, although subtle imperfections are visible in places. In most scenes, the tonal transitions are smooth and well-rendered, providing a natural viewing experience. In more demanding sequences, such as a darkly coloured sky, slight issues may arise; however, these do not significantly affect the overall visual experience. In the test scene dominated by red hues, slight clipping of the brighter areas can be observed, but it is subtle enough not to interfere with viewing. Overall, the fluidity of tonal transitions on the S90D television is solid, ensuring good reception of content.

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.

The Samsung OLED 48 S90D television performs very well in smoothing tonal transitions. Thanks to the applied technology, the transitions between colours are more fluid and natural. There is also the option to use the noise reduction function, which further smooths tonal transitions, which can be useful in certain situations. However, it is worth remembering that enabling noise reduction can also lead to the smoothing of desired film grain, which in turn can reduce the cinematic atmosphere of the image. For this reason, caution is advised when using this function, as it is better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels at scaling images from lower resolutions. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and correct, looking natural and detailed as a result. Moreover, the branches of trees are well replicated, showing no strong jaggedness that could detract from the quality of the image. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer a variety of content sources such as regular aerial/cable television.

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.

Blur (native resolution, maximum refresh rate):

The S90D television is equipped with a 120 Hz panel, with the possibility of "overclocking" to 144 Hz with the appropriate PC configuration, ensuring exceptional motion fluidity. For years, Samsung has offered a variety of image sharpness settings on a ten-point scale, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any blurring. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television an ideal choice for gamers and sports enthusiasts.

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.

The Samsung OLED 48 S90D television is excellently tailored to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster screen responsiveness, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustments of settings such as screen ratios, which can be particularly useful in various types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image fluidity. Although the lack of Dolby Vision support may be a downside, it is worth noting that this technology is not as widely used in games as it is in films. Nevertheless, the S90D still offers excellent features for gamers, making it an outstanding choice for those seeking high-quality visuals and advanced gaming technologies.

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.

Samsung's OLED features an exceptionally low input lag, regardless of resolution and frame rate, in both SDR and HDR modes. Results around 10 ms are truly impressive and significantly enhance the gaming experience. Such a low input lag ensures immediate responsiveness to on-screen actions, which is crucial in dynamic games where every millisecond counts. This allows users to enjoy fluidity and precision, making the S90D television an excellent choice for those prioritising gaming performance.

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 Samsung S90D / S94D 48" (WRGB OLED) Compatibility with PC
Review TCL P7K / P79K Compatibility with PC

The Samsung OLED 48 S90D television works perfectly with a PC. Fonts are clearly visible, which makes reading text and using applications easier. Additionally, it supports 4:4:4 chroma at 4K resolution and a refresh rate of 144 Hz, ensuring full colour reproduction and image sharpness. It is worth highlighting that the input lag of just 5 ms is extremely beneficial, especially for gamers and professionals working with graphics. With such low latency, using the television as a monitor becomes a pleasure, allowing for comfortable and responsive work. The S90D television is an excellent choice for users seeking performance and quality in everyday computer use.

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 S90D television, thanks to OLED technology, are unparalleled. OLED offers excellent colour and contrast reproduction, even at wide viewing angles, which ensures that the image remains sharp and vibrant from almost any perspective. Users can enjoy a consistent visual experience, regardless of where they are viewing the screen.

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.

When watching during the day, the Samsung OLED 48 S90D performs well, achieving an average brightness of around 320 nits, which is a decent result for OLED technology in a 48-inch size. Thanks to the satin finish, reflection suppression is at an acceptable level, allowing for comfortable viewing even in bright rooms. The only noticeable downside to this technology, rather than the television itself, is the brightness at 100% white screen fill. In such conditions, OLED can struggle to achieve extremely high brightness. Such situations can be seen when we want to watch winter sports, for example, ski jumping.

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.

The Samsung OLED 48 S90D television offers a range of features that significantly enhance user comfort, making it the ideal device for entertainment in the comfort of your home. The Tizen system, on which this model is based, is a modern and advanced platform that provides users with an intuitive and smooth experience. With a user-friendly interface, navigation through applications and settings is quick and intuitive, making it easy for even less tech-savvy individuals to use the television. Tizen supports a rich set of applications, including all popular streaming services such as Netflix, YouTube, and Amazon Prime Video. A new feature for 2024 is the availability of voice search in Polish. It's also worth noting the eco-friendly solar remote, which is not only environmentally friendly but also practical for daily use. For example, the remote is capable of controlling multiple devices connected to the television, so there is no need to use multiple remotes. Additionally, the television supports AirPlay, allowing for easy content sharing from Apple devices such as iPhone or iPad. The S90D OLED 48 also allows for the connection of various Bluetooth devices, such as mice, keyboards, or headphones, which increases its versatility and enables user experience personalisation. This means that users can easily adjust their settings to make the most of the television's capabilities. The only downside that can be pointed out is the lack of USB recording support. For some users, this may be a limitation, especially for those wishing to archive their favourite shows or films. Despite this, the S90D television offers many advanced features and technologies, making it an excellent choice for anyone seeking high-quality entertainment in their home.

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.

The Samsung S90D is equipped with a built-in player that supports most popular video formats, allowing for convenient playback of films from various sources. The player also supports subtitles in Polish and enables users to customise the font colour, increasing comfort when watching content with subtitles. In terms of photo formats, the television handles many of them; however, one of the few downsides is the lack of ability to play the popular PNG format. Nevertheless, the overall file playback capabilities of the S90D are at an excellent level.

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 Samsung OLED 48 S90D television provides good sound quality, with clear and balanced tones. The sound is clear, and the bass is well audible, which enhances the viewing experience. Even at the highest volume, the sound remains clear, although the television itself is not very loud.

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.
