Compare: TCL P7K / P79K vs Hisense U7S / U77SE

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.

Hisense U7S is the latest iteration of the U7 series, whose biggest advantage remains its price-to-quality ratio. You get a Mini LED TV with local dimming, which really improves black levels and gives the picture depth for evening viewing. During the day, the generous brightness headroom is useful, so you don't have to immediately cover the windows. It's not a device without compromises, but as an everyday TV it makes a lot of sense. Gamers benefit a lot as well. The U7S supports high refresh rates from consoles and PCs, has an extensive set of gaming features, and responds very quickly to controller input. Pleasingly, the low input lag is preserved in Dolby Vision too. Add in the smoothly running VIDAA, which offers both Smart features and handy extras for regular TV, and the package is fairly versatile, though compared with last year's U7Q it's hard to call it a big step forward. Unfortunately there are also things that clearly bother us. The first is motion blur. The panel has a high refresh rate, but its pixels don't always keep up, so visible trails follow moving objects. Fans of sports and fast-paced games will notice this especially. The second issue is HDR, which the TV shows somewhat "its own way." Instead of sticking to the brightness encoded in the content, it strongly brightens parts of the image. That was probably meant to look more impressive, but it often has the opposite effect: the scene becomes over-bright, loses depth, and clearly departs from the creators' intent. It's a shame this behavior can't be effectively corrected even during calibration. Despite these remarks, the U7S remains an interesting choice if you're looking to get as much as possible for a reasonable price. Compared with basic LCDs without local dimming, which you can still find at a similar price, it primarily offers much better blacks. And that's exactly its greatest strength. You don't have to reach for an expensive model to get a Mini LED whose advantages are actually noticeable when watching. If you accept its flaws, the Hisense U7S can above all be a cost-effective purchase.

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".

Hisense U7S delivers good black levels, especially for an entry-level Mini LED model. The 55-inch sample we tested uses 192 local dimming zones, which work well with the VA panel. In most of our scenes contrast ranged from about 21,000:1 to over 51,000:1, and in one it even exceeded 500,000:1. In many films you can clearly see the difference. Dark scenes have depth and blacks don't look grey like on many cheaper LCDs without local dimming.

It gets worse when the screen shows a lot of small bright objects on a dark background (for example the scene shown below). There are too few zones to light each of them separately, so small objects have a bright ring around them. This so-called halo effect is most noticeable when watching in a dark room. In the most demanding shot the contrast fell to around 5,650:1 and here the backlight limitations are already apparent. Even so, given the class of the television, it is hard to call this a flaw, because many Mini LED televisions in a similar price range will have comparable problems.

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%.

The Hisense U7S has considerable potential for HDR display, but it cannot exploit that potential in every scene. On a test pattern it reaches around 1,100 nits, so the backlight itself is very strong. In our brighter film scenes we measured about 640 to 745 nits. That is still plenty for the sun or bright highlights to have a clear bloom and to show an advantage over SDR material. When the TV needs to brighten a larger portion of the image, it handles it fairly well.

The problem appears with small highlights on a dark background. Each of the 192 zones covers an area much larger than a tiny point on the screen. If the TV were to light that whole zone strongly, it would also brighten the area around the highlight. Hisense tries to avoid that and dims the entire zone. This makes blacks look better, but a small bright object that should attract the eye also loses intensity. That is why in two more demanding scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small highlights are noticeably muted. The U7S therefore prioritises preserving deep blacks, even at the expense of bright details. With that number of zones it is an understandable compromise, but worth bearing in mind — the peak 1,100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense describes the U7S as ULED, but that is a marketing name, and it is a PFS phosphor backlight that expands the colour palette here. In our measurements the TV covered about 91% of the DCI-P3 colour space and 71% of BT.2020. Those are good results, though they fall short of the best screens on the market. The largest shortfall is in green — the TV does not even reach the DCI-P3 boundary here, so the most intense shades will be less saturated than they should be. Most colours in HDR films and series still look suitably vibrant. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

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.

Out-of-the-box colours on the Hisense U7S are decent, but there are a few areas to improve. In SDR there is a red bias in the white balance, which makes the picture too warm and, in places, slightly pink. You can notice this on faces and on bright, neutral surfaces. The gamma also runs below the target, so the TV brightens the image, particularly in darker areas. That makes shadow detail easier to see, but the scene loses some of its depth.

In HDR the white balance is somewhat more even, but not entirely neutral, with a shortage of blue in the mid-tones and a lack of red in the brightest parts. A bigger issue is how brightness is rendered. The EOTF curve shows a large portion of the mid-tones being lifted, causing the picture to look brighter than the source intends. Color Checker measurements are also weaker than in SDR: many errors are around 3 to 4, and some reach as high as 8. Colours can therefore look attractive, but they are not always faithful to what we should see. There is room for improvement here and we will see how much can be corrected through calibration.

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.

Calibration of the Hisense U7S brought the biggest improvements with SDR material. We managed to even out the white balance, so the previous warm tint has gone and whites and greys now look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the picture unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. That means the picture is very well set up for watching regular TV and SDR films. It wasn't as smooth in HDR. There is no effective way to correct the EOTF curve, so the TV still interprets a film's brightness somewhat on its own. It brightens parts of the picture and can dim the brightest elements depending on the scene and the behaviour of the local dimming. Calibration could not eliminate this. This is also reflected in the Color Checker results, where many errors remain around 3–4 and a few exceed 7. So the result in SDR is really very good, but in HDR we must accept that the TV adds its own interpretation of brightness to the image.

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.

Smoothness of tonal transitions is one of the strengths of the Hisense U7S. HDR10 content performs particularly well, with colours blending gently from one to another without obvious banding. Even in dark scenes it is hard to find significant issues. Minor colour banding becomes visible only in brighter shots, but during normal viewing it is hardly noticeable. It is slightly worse in Dolby Vision, where the boundaries between tones can be more apparent. For that reason Hisense loses some points with us, although overall this remains a very good result and one of the better performers in its class.

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.

The handling of lower-quality material is fairly mediocre on the Hisense U7S. The Pentonic 700 chipset used here does not cope particularly well with strong compression artefacts. The menu includes a "Smooth and Gradient Image" function, but its performance leaves much to be desired. At the low setting tonal transitions show little improvement, although at least the image does not suffer. The medium and high settings still do not remove obvious banding between shades, and they begin to blur details; in our test material even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you do use this feature, stick to the low setting. Its current behaviour needs refinement, but that is mainly down to the chipset used here.

Upscaling to 4K performs much better. Lower-resolution content gains in legibility, edges are well reproduced, and fine elements look sharp. That does not mean it recovers details that were never in the recording, but the TV makes good use of what it receives from the source. Another plus is that it does not crop the image edges, even with an SD signal.

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.

Motion handling on the Hisense U7S is decent thanks to the 144 Hz refresh rate. For films there is also a motion smoother with adjustable judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if jerky camera pans bother you. The high refresh rate is also useful for sports and gaming, but unfortunately it does not solve the panel's biggest problem.

That problem is pixel response time. Fast-moving objects leave long, clearly visible trails, as our UFO test shows. It looks worst on dark backgrounds, where the trail behind the object is particularly pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

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.

The Hisense U7S has a lot to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz at Full HD, 1440p, and 4K, so modern consoles’ capabilities are well used. When connected to a PC you can use 144 Hz at 4K or switch the resolution to Full HD and run 240 Hz. So there’s a wide choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate does not eliminate. VRR and ALLM are also present. The first helps prevent tearing when frame rates in a game change. The second automatically switches the TV into game mode, so you don’t have to dig through the menu each time. VRR works from 48 to 240 Hz, with the highest refresh rate available in Full HD. Xbox users can also play in Dolby Vision, including at 120 Hz. Importantly, this format does not introduce significant input lag here. The Game Bar also looks very good. It’s easy to read, visually appealing, and lets you quickly check what signal the TV is receiving. There are also handy gaming settings at your fingertips, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the entire menu.

Our biggest complaints concern HGiG. Hisense continues to do its own tone mapping, which makes setting HDR on the console confusing. You adjust a checkerboard test pattern and the TV continuously adapts how it looks. As a result, the moment the pattern disappears does not correctly indicate the screen’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR peak brightness on the console to about 900 to 1000 nits, rather than relying on the configurator.

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.

In terms of input lag, the Hisense U7S performs excellently. At 60 Hz we measured 14 to 16 ms, and at 120 Hz just 9 to 10 ms. The controls are responsive and even in fast-paced games the TV doesn't add any noticeable delay. Importantly, Dolby Vision performs just as well: 14 ms at 60 Hz and 9 ms at 120 Hz mean you don't have to give up the format for fear of added latency. The motion blur described earlier is a separate issue: the screen reacts quickly to inputs, but the pixels do not always keep up with changes in colour.

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.

When connected to a PC you can run 4K at 144 Hz, with G-Sync enabled and input lag of around 10 ms. It's a good setup for gaming, although panel smearing is still noticeable in fast-moving scenes. 4:4:4 chroma subsampling also works correctly, even at the maximum refresh rate, so coloured text and small desktop elements remain legible.

For web browsing or occasional work the U7S is quite suitable, but not all fonts look equally sharp. Our main complaint is small, dark text: thin strokes of letters can disappear and characters look uneven. It's hard to notice that from the sofa, but when working up close, especially with text or spreadsheets, it can become distracting.

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.

Viewing angles are unfortunately a weak point of the Hisense U7S. Even after shifting to the side, colours lose saturation, blacks become lighter and the picture looks washed out. At a 45-degree angle we measured as much as a 74% drop in brightness, so the difference compared with watching head-on is really significant. This is a typical limitation of VA panels. When seated centrally you can appreciate its good contrast, but people at the far ends of a wide sofa will see a noticeably poorer picture. The U7S is therefore best suited to setups where seating is positioned as directly in front of the screen as possible.

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 Hisense U7S handles daytime viewing well. In SDR we measured an average of around 664 nits, and depending on the screen content brightness ranged roughly between 500 and 800 nits. Even with an all-white image it stays above 500 nits, so a sports broadcast or a bright TV programme does not suddenly look dimmed. That is plenty of headroom for comfortable viewing in most living rooms. The satin coating does a decent job suppressing reflections, but a window opposite the TV will still be visible. In the photo it is clear that its reflection can obscure part of the picture, so high brightness alone does not solve everything. A plus is the handling of blacks and colours in daylight, which do not become overly grey. Overall the U7S performs well in a bright room, though you should position it to avoid direct reflections from windows.

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.

Smart TV: VIDAA

VIDAA HOME OS on the Hisense U7S is feature-rich, yet runs quickly and does not complicate everyday use. Besides apps there is AirPlay for streaming from Apple devices and Miracast, which lets you mirror a computer’s screen. There is also voice search in Polish, so instead of typing a film title with the remote you can simply say it. You can also connect a keyboard and mouse. So there is little to complain about in terms of smart features, although before buying it is worth checking the availability of specific apps you use, because it is not as extensive as on competing systems.

Conventional features and the remote

Hisense has not forgotten people who watch regular TV. The U7S lets you record programmes from terrestrial TV to USB and schedule recordings for later. There is teletext, the ability to listen to audio with the screen turned off, and support for Bluetooth headphones. Usefully, headphones can work at the same time as the TV speakers, so one person can use them, for example a senior, while others continue to listen normally. One notable omission is picture-in-picture, or PiP.

We were not fond of the remote itself. It feels very plastic and looks rather cheap, but it does its job well. It has a full numeric keypad, plenty of shortcuts and operates via radio, so you do not need to point it at the screen. It is a shame the buttons are not backlit. Hisense reserves more stylish versions of the remote for higher-end models, such as the U7S Pro.

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 USB player in the Hisense U7S handles most common file types. It played our H.264 and H.265 material without problems, including high-bitrate 4K clips and a Dolby Vision test file. SRT and SUB subtitles work, including Polish characters and changes to font colour. Not everything ran, though. AV1 and H.266 VVC files did not play, nor did ASS and TXT subtitles. Audio performance is good, from ordinary MP3s to FLAC 96 kHz/24-bit, although AIFF and DSD are not supported.

Our biggest reservations concern photos. The range of supported formats is broad — besides JPEG and PNG, WebP and TIFF also work, but HEIC won’t open. Resolution handling is odd. The TV displayed 4, 6, 8, 16 and 32 Mpix images but couldn’t cope with 10, 12 or 24 Mpix files. So this isn’t a simple image-size limitation. The player is perfectly adequate for movies and music, but when showing holiday photos you may find you need to convert some files beforehand.

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.

The USB player in the Hisense U7S handles most common video and music files well. It supports 4K content, including a Dolby Vision file we tested, and displays Polish characters correctly in subtitles. It should therefore be sufficient for everyday use with a USB stick, although there are problems with less common formats. Our main reservations concern photos. The TV handles photo resolutions rather inconsistently and can open a larger image but refuse to display a smaller one. That can be irritating when browsing a holiday album, as you cannot be sure that all photos will work. Some will require prior preparation on a computer.
