Compare: TCL P7K / P79K vs Hisense U7S / U77SE

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.

Hisense U7S is the latest iteration of the U7 series, whose biggest advantage remains its price-to-performance ratio. You get a Mini LED TV with local dimming, which genuinely improves black levels and gives the picture more depth for evening viewing. During the day a generous brightness reserve helps, so you don't have to rush to close the curtains. It's not a device without compromises, but as an everyday TV it makes a lot of sense. Gamers get a lot too. 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 maintained even in Dolby Vision. On top of that there's the smooth-running VIDAA, which offers both Smart features and handy extras for regular TV. Overall it's quite versatile, although 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 smearing. The panel has a high refresh rate, but its pixels don't always keep up, so moving objects leave noticeable trails. Fans of sport and fast-paced games will feel this most. The second issue is HDR, which the TV handles a bit 'its own way'. Instead of sticking to the brightness encoded in the content, it aggressively brightens parts of the image. The aim was probably to make things more striking, but often the opposite happens: a scene becomes overbright, loses depth and clearly departs from the creators' intent. It's a shame that this behaviour can't be effectively corrected even during calibration.

Despite these caveats the U7S remains an interesting choice if you're after as much as possible for a reasonable price. Compared with basic LCDs without local dimming, which you can still find at similar price points, it primarily offers much better black levels. And that's where its biggest strength lies. You don't need to reach for an expensive model to get a Mini LED whose benefits are actually visible in viewing. If you accept its flaws, the Hisense U7S can above all be a very good-value purchase.

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".

The Hisense U7S shows good black levels, especially for one of the entry-level mini-LED models. The 55-inch test size uses 192 local dimming zones that 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 plainly see it — dark scenes have depth, and blacks don’t glow grey like on many cheaper LCDs without local dimming.

It’s worse when the screen shows lots of small bright objects against a dark background (for example the scene shown below). There aren’t enough zones to light each of them individually, so you can see a bright halo around small objects. This so-called halo effect is easiest to spot when watching in a dark room. In the most demanding shot the contrast dropped to about 5,650:1, and here the backlight limitations are clearly noticeable. Despite that, given the TV’s class, it’s hard to call this a fault, because many mini-LED TVs in a similar price range will have similar problems.

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%.

The Hisense U7S has considerable HDR potential, but it can’t make full use of it in every scene. On a test pattern it reaches about 1100 nits, so the backlight is genuinely strong. In our brighter film scenes we measured around 640 to 745 nits. That’s still enough for the sun or bright highlights to have a distinct bloom and to show an advantage over SDR material. When the TV needs to light a larger portion of the image, it handles it quite well.

The problem appears with small lights on a dark background. Each of the 192 zones covers an area considerably larger than a tiny point on the screen. If the TV were to drive such a zone strongly, it would brighten the surrounding area along with the light. Hisense tries to avoid that and dims the whole zone. Blacks look better as a result, but a small bright object that should draw the eye also loses intensity. That’s why in two tougher 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 keeping deep blacks, even at the expense of bright details. With this number of zones it’s an understandable compromise, but it’s worth remembering that the peak 1100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense markets the U7S as ULED, but that’s a marketing name; the wider colour gamut here is achieved by a PFS phosphor backlight. In our measurements the TV covered about 91% of the DCI-P3 space and 71% of BT.2020. Those are good results, though a little short of the best screens on the market. The biggest shortfall is in green — the TV doesn’t even reach the DCI-P3 boundary there, so the most intense green hues will be less saturated than they should be. Most colours in HDR films and series still look suitably vivid, however. A positive is the repeatability of the results: gamut coverage on test patterns and in film scenes is practically identical.

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.

Factory colours on the Hisense U7S are decent, but there are a few things to fix. In SDR the white balance favours red, so the image looks too warm, in places with a slightly pink tint. You can see this on faces and bright, neutral surfaces. Gamma also runs below the target, so the TV brightens the image, especially in darker areas. That makes it easier to see shadow detail, but the scene loses some of its depth.

In HDR the white balance is a bit more even, but not completely neutral, with midtones lacking blue and the brightest parts lacking red. A bigger problem is the way brightness is reproduced. The EOTF curve shows that a large portion of the midtones is boosted, making the image appear brighter than the source material intends. Color Checker measurements also fare worse than in SDR: many errors are around 3 to 4, and individual ones reach as high as 8. Colours can therefore look attractive, but they're not always faithful to what we should be seeing. There’s room for improvement and we’ll see how much can be corrected with calibration.

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.

Calibrating the Hisense U7S did the most for SDR content. We managed to even out the white balance, so the earlier warm tint is gone and whites and greys look neutral. Gamma now sits very close to the reference, so the TV no longer brightens the image unnecessarily and darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. For watching regular TV and SDR films, this delivers a really well calibrated picture. Calibration in HDR wasn’t as smooth. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the film’s brightness a bit on its own. It brightens parts of the image and, depending on the scene and local dimming, can tone down the brightest elements. That couldn’t be eliminated by calibration. This also shows up in the Color Checker results, where many errors remain around 3–4 and some exceed 7. In SDR the result is therefore very good, but in HDR we have to 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 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.

The smoothness of tonal transitions is one of the Hisense U7S’s stronger points. HDR10 content performs particularly well, with colours gently flowing from one to another without noticeable banding. Even in dark scenes it's hard to find significant issues. Minor tone joins only become visible in brighter shots, but during normal viewing they rarely draw attention. It's a bit worse with Dolby Vision, where the boundaries between tones can be more apparent. That's why Hisense loses some points with us, although overall it's still a very good result and one of the better performers in its class.

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.

The processing of lower-quality material in the Hisense U7S is fairly average. The Pentonic 700 chipset used here doesn't cope particularly well with the effects of heavy compression. There's a "Smooth and Gradient Picture" function in the menu, but its performance leaves a lot to be desired. At the low setting it's hard to see any improvement in tonal transitions, though at least the picture doesn't suffer. Medium and high settings still don't remove visible banding between tones and begin to blur details; in our clips parts of characters' faces even vanished. Interestingly, film grain remains untouched at every level. If you do use this function, stick to the low setting. Its current performance needs refinement, but that's mainly down to the processor used here.

Upscaling to 4K performs much better. Lower-resolution content gains clarity, edges are well reproduced and fine details look sharp. That doesn't mean the TV can recover details that weren't in the recording, but it makes good use of what's provided by the source. Another plus is the lack of edge cropping, even with an SD signal.

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.

Motion handling on the Hisense U7S is decent thanks to its 144 Hz refresh rate. For films there's also a motion smoothing option with adjustable judder and blur reduction. You can keep a more cinematic feel to motion or increase smoothness if choppy camera pans bother you. High refresh is also useful for sport and gaming, but unfortunately it doesn't solve the panel's biggest problem.

The issue is pixel response time. Fast-moving objects leave long, distinct trails, as our UFO test shows. It's worst on dark backgrounds, where the trail is particularly pronounced. So motion can be smooth, but the moving object loses sharpness, and that difference on the U7S is fairly easy to spot.

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.

The Hisense U7S has plenty to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz in Full HD, 1440p and 4K, so modern consoles’ capabilities are well utilised. 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 lot of choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate doesn’t eliminate. VRR and ALLM are present as well. VRR helps keep the picture tear-free when a game’s frame rate changes. ALLM automatically switches the TV into game mode, so you don’t have to go into 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 at 120 Hz. Importantly, that format does not cause significant input lag here. The Game Bar also looks great. It’s clear and attractive, and lets you quickly check what signal the TV is receiving. Handy gaming settings are close to hand too, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the whole menu.

Our biggest complaint is HGiG. Hisense keeps doing its own tone mapping, which makes setting up HDR on the console confusing. You adjust the checkerboard pattern, and the TV continually alters its appearance. As a result, the point at which the pattern disappears does not correctly indicate the display’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR brightness on the console to around 900 to 1000 nits, rather than rely on the configurator.

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.

In terms of input lag the Hisense U7S performs excellently. At 60 Hz we measured 14–16 ms, and at 120 Hz just 9–10 ms. Input is responsive and even in fast-paced games the TV doesn't introduce 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 forgo the format for fear of added latency. The smearing described earlier is a separate issue. The screen reacts quickly to inputs, but the pixels don't always keep up with colour changes.

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.

Po podłączeniu komputera możemy korzystać z 4K przy 144 Hz, działającego G-Sync i opóźnienia na poziomie 10 ms. To dobry zestaw do grania, choć w dynamicznych scenach nadal daje o sobie znać smużenie matrycy. Poprawnie działa też chroma 4:4:4, również przy maksymalnym odświeżaniu, dzięki czemu kolorowe napisy i drobne elementy pulpitu pozostają czytelne.

Do przeglądania internetu czy okazjonalnej pracy U7S nadaje się całkiem dobrze, ale nie wszystkie czcionki wyglądają równie wyraźnie. Najwięcej uwag mamy do drobnego, ciemnego tekstu — cienkie fragmenty liter potrafią zanikać i znaki wyglądają nierówno. Z kanapy trudno to zauważyć, natomiast przy pracy z bliska, szczególnie z tekstem czy arkuszami, może już przeszkadzać.

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.

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 a brightness drop of as much as 74%, so the difference compared with watching straight on is really significant. That's a typical limitation of VA panels. When seated centrally we can appreciate its good contrast, but people sitting at the far ends of a wide couch will see a noticeably worse picture. The U7S is therefore best suited to setups where viewing positions are as close to directly in front of the screen as possible.

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.

Hisense U7S handles daytime viewing well. In SDR we measured on average about 664 nits, and depending on the onscreen content the 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 won't suddenly look dim. That's enough headroom for comfortable viewing in most living rooms. The satin finish does a decent job of suppressing reflections, but a window opposite the TV will still be visible. The photo shows clearly that its reflection can obscure part of the picture, so high backlight alone doesn't solve everything. On the plus side, blacks and colours hold up in daylight and don't become overly grey. Overall the U7S will work well in a bright room, although it's worth positioning it to avoid direct window reflections.

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.

Smart TV: VIDAA

VIDAA HOME OS on the Hisense U7S is feature-rich, yet runs quickly and doesn't complicate everyday use. Besides apps, there is AirPlay for streaming from Apple devices and Miracast, which lets you mirror a computer screen. Voice search in Polish also works, so instead of typing a film title with the remote you can just say it. You can also connect a keyboard and mouse. It's hard to complain about the Smart features, though before buying it's worth checking the availability of the specific apps you use, because the selection isn't as extensive as on competing systems.

Classic features and the remote

Hisense hasn't forgotten viewers who watch regular TV. The U7S lets you record programmes from terrestrial TV to USB and schedule recordings for later. There's teletext, the option to listen to audio with the screen off, and support for Bluetooth headphones. Usefully, headphones can operate at the same time as the TV speakers, so one person, for example a senior, can use them while others continue to listen normally. The main omission is really picture-in-picture, PiP.

We weren't keen on the remote itself. It's quite plasticky and looks rather "cheap", but it does its job well. It has a full numeric keypad, plenty of shortcuts and controls the TV via radio, so you don't have to point it at the screen. It's just a shame the buttons aren't backlit. Hisense reserves more elegant remote versions for higher-end models, such as the U7S Pro.

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 USB player in the Hisense U7S handles most common files. It played our H.264 and H.265 material without any problems, including high-bitrate 4K recordings and a Dolby Vision test file. SRT and SUB subtitles work, as do Polish characters and font colour changes. Not everything could be run, though. AV1 and H.266 VVC files failed to play, as did ASS and TXT subtitles. Audio support is good, from simple MP3s to FLAC 96 kHz/24 bit, although AIFF and DSD are not supported.

Our biggest issues are with photos. The selection of supported formats is wide — besides JPEG and PNG it also handles WebP and TIFF, but HEIC won’t open. The way it handles resolution is odd too. The TV displayed images at 4, 6, 8, 16 and 32 Mpix, but couldn’t cope with 10, 12 or 24 Mpix files. So it’s not a straightforward size limit. The player is perfectly adequate for movies and music, but when showing holiday photos you may find some files need converting first.

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.

The USB player in the Hisense U7S handles most common movies and music 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 it can struggle with less common formats. Our biggest reservations concern photos. The TV treats image resolutions quite selectively and may open a larger photo but refuse to display a smaller one. When browsing a holiday album this can be annoying, because you can't be sure all the photos will work. Some will need to be prepared on a computer beforehand.
