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 significantly more than we could expect in its price range. Its undeniable advantage is the VA panel, guaranteeing deep blacks and high contrast, and a surprisingly rich package for gamers (with VRR and 120 Hz support at lower resolutions) makes it a phenomenal choice for console owners. The whole package is tied together by the functional Google TV system. Of course, 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 competitor turns out to be… its more refined sibling, the P8K. Often FOR a small extra charge, we get a device a class higher – with a native 4K 144 Hz panel, significantly better audio system, and generally higher build 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-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 starts with the issue of black depth and contrast, which are parameters defining the plasticity and realism of the observed world. And here, the TCL P7k/P79k immediately lays its strongest asset on the table – a VA-type panel. It is its construction that makes the native relationship 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 achieved black has a noble depth, which allows for building an engaging viewer experience. To illustrate the scale, it is worth mentioning that competitive 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, entering the territory of models oriented towards affordability, we must be aware of certain compromises. In the discussed television, we will not find an advanced local dimming system that could further enhance the impression 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".

The Hisense U7S shows good black levels, especially for one of the entry-level Mini LED models. The 55-inch unit we tested 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 see it — dark scenes have depth, and blacks don't glow gray like on many cheaper LCDs without local dimming.

It gets worse when the screen contains a lot of small bright objects on a dark background (for example, in the scene shown below). There aren't enough zones to illuminate each one separately, so you can see a bright halo around the small objects. This so-called halo effect is easiest to notice when watching in a dark room. In the most demanding shot contrast fell to about 5,650:1, and here the backlight limitations are clearly visible. Even so, 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 evaluating the HDR effect, we must make it clear and without marketing embellishment: the P7K/P79K is not and was never meant to be a master in this field. The maximum peak brightness that this panel can generate is only around 300 nits. This is a borderline value, a sort of thin red line between what can be considered a barely satisfactory HDR signal and what is really 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 parts of the content rarely exceeded the threshold of 200-250 nits. Therefore, this is not a television that would allow content produced in a wide tonal range to truly shine, and we must openly acknowledge that.

Unfortunately, the issue of color reproduction is presented equally restrained. Although the manufacturer positions this model in 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 color gamut is only 86%. Compared to the market, this is at best an average result, as most devices that employ additional layers to expand the color spectrum easily achieve values at a minimum level of 90-92%.

The Hisense U7S has considerable HDR potential, but it can't use it 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's still enough for the sun or bright highlights to have a noticeable glow and to show an advantage over SDR material. When the TV needs to illuminate a larger portion of the image, it does quite well.

The problem appears with small lights 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 strongly light such a zone, it would also brighten the surrounding area along with the light. Hisense tries to avoid that and dims the entire zone. Black levels therefore look better, 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 lights are noticeably muted. The U7S therefore prioritizes maintaining deep blacks, even at the expense of bright details. With this number of zones that's an understandable compromise, but it's worth remembering — the 1,100-nit peak tells us about the backlight's capability, not how brightly the TV will render every element of a film.

Colors

Hisense calls the U7S ULED, but that's a marketing name; the wider color gamut here comes from a PFS phosphor backlight. In our measurements the TV covered about 91% of DCI-P3 and 71% of BT.2020. Those are good results, although it falls short of the best screens on the market. The biggest shortfall is in green — the TV doesn't even reach the DCI-P3 target there, so the most saturated shades will be less intense than they should be. Most colors in HDR films and series, however, still look suitably rich. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

Every reliable image quality assessment must begin by selecting the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was confidently made for the "Film" mode. It is this mode that presents an image closest to the creators' intentions, avoiding both the exaggerated brightness of 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 free from a few stumbles. The most noticeable flaw turned out to be an imperfectly adjusted white balance. A slight dominance of the blue component gives the image a subtly cool, chilly character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the grayscale in a standard dynamic range – the gamma curve is executed almost perfectly. A minor reservation can only be made for 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 TCL's software, however, was the interpretation of the HDR signal, which is 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 midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we proceeded to the professional calibration process.

The out-of-the-box colors on the Hisense U7S are decent, but there are a few things to improve. In SDR there's a red bias in the white balance, which makes the image too warm and in places slightly pink. You can notice this on faces and on bright, neutral surfaces. Gamma also runs below the reference, so the TV brightens the image, especially in darker areas. That makes shadow details easier to see, but the scene loses some of its depth.

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

The calibration process turned out to be a home run, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the TV's tendency to emphasize cool tones, restoring the whites to their natural neutrality. Furthermore, precise adjustments allowed us to correct a slight error in the gamma curve, so the darkest areas of the image regained their proper depth, without a trace of unnatural brightening. The effects are measurable and impressive – in the ColorChecker test, the vast majority of color reproduction errors fell below the perceptual threshold, achieving a deltaE value below 2. This is a result that would not shame much more expensive constructions. Unfortunately, in the case of HDR content, we hit a wall in the form of the inherent limitations of the panel itself. And although we managed to bring the colors in line, the software's specifics mean that the TV still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration brings tremendous added value, but one must be aware that it cannot overcome certain physical barriers. A slight boost in black levels, resulting from the lack of local dimming, and limited peak brightness mean that HDR content will not 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 the viewing of SDR materials.

Calibration of the Hisense U7S helped most with SDR content. We managed to even out the white balance, so the previous warm cast is gone and whites and grays look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the image unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors fall below 2. That yields a really well-calibrated picture for regular TV and SDR movies. It didn't go as smoothly in HDR. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the content's brightness a bit on its own. It brightens parts of the image and can dim the brightest elements depending on the scene and the local dimming behavior. Calibration couldn't eliminate this. It shows up in the Color Checker results as well, where many errors remain around 3–4 and individual ones exceed 7. So in SDR the result is very good, but in HDR we have to accept that the TV adds its own interpretation of brightness to the image.

The issue of fluidity in 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 color 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 unsightly dithering. This artifact is particularly noticeable on demanding test patterns – such as the one depicting an actor submerged in red water – where a rough, unnatural texture appears on uniform color surfaces, revealing the digital nature of the image. This is particularly disappointing as it is not a new issue. It seems to be a sort of legacy from previous generations of budget TCL models, which is a shame because it constitutes a flaw on what is essentially 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 material performs especially well, with colors blending gently into one another without noticeable banding. Even in dark scenes it’s hard to find major issues. Minor color stepping is visible only in brighter shots, but during typical viewing it usually doesn’t attract attention. It looks a bit worse in Dolby Vision, where boundaries between shades can be more apparent. That’s why Hisense loses some points from us, although overall this is still 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 digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship designs; nevertheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The feature that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, such as from the YouTube service. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also competently handles upscaling, which is the task of raising low-resolution materials to 4K standard. The output image, although it may seem a bit too sharp out of the box, fortunately, is not a problem. The software allows for easy adjustment of this parameter using a sharpness slider, so the final appearance can be easily tailored to personal preferences.

The handling of lower-quality material on the Hisense U7S is fairly mediocre. The Pentonic 700 chipset used here doesn't cope well with the effects of heavy compression. The menu includes a "Smooth & Gradient" picture option, but its performance leaves much to be desired. At the low setting it's hard to notice any improvement in tonal transitions, although at least the image isn't degraded. The medium and high settings still don't remove visible banding between shades and begin to smear details; in our test clips even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you use this feature, we'd stick with the low setting. Its current behavior needs refinement, but that's mainly down to the processor used. Upscaling to 4K performs much better. Lower-resolution footage gains clarity, edges are well reconstructed, and fine elements look crisp. That doesn't mean it can recover details that weren't in the recording, but the TV makes good use of what it gets from the source. Another plus is that it doesn't crop the image edges, even with an SD signal.

The issue of fluidity and sharpness of the image in motion 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 already defines its capabilities and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During rapid camera movements, the image loses sharpness, and the panel itself also shows a slight tendency to blur, 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 independently decide on the final character of the motion – from a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows users to tailor the viewing experience to their own preferences.

Motion handling on the Hisense U7S is pretty good thanks to the 144 Hz refresh rate. For movies we also have a motion smoothing feature that lets you adjust judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if abrupt camera shifts bother you. In sports and games the high refresh rate is also useful, but unfortunately it doesn't solve this panel's biggest problem.

The culprit is pixel response time. Fast-moving objects leave long, noticeable trails, as our UFO test shows. It's worst on dark backgrounds, where the trail behind the object is especially 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 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 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 completed 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 TV easily supports high refresh rate signals of 120 Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners who know full 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 avid tournament gamers, it offers a package of options for the casual or occasional console user that is hard to find among many competitors at this price point.

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. Even 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, when the lag drops nearly in half, reaching values below 10 ms. Such responsiveness means that every command from the controller is transferred to the screen in the blink of an eye, something not only professionals will appreciate, but anyone who values smooth and immediate 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, with 14 ms at 60 Hz and 9 ms at 120 Hz, so you don't have to give up that format for fear of added latency. The motion smearing described earlier is a separate issue: the panel responds quickly to input, but the pixels don't always keep up with color changes.

We finally come to an area that can undoubtedly be described as the biggest Achilles' heel of the TCL P7K/P79K – its cooperation 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 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 – they, especially colorful ones, become jagged, surrounded by artifacts, and simply hard to read. This is not the end, as in PC mode, a significant issue with 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 additional hertz and G-Sync technology, but these are not benefits that could compensate for the fundamental shortcomings in displaying a static interface. The verdict is therefore clear: while it can still hold up as a screen solely for gaming on PC, in the role of a monitor for work or internet browsing, the P7K/P79K simply performs poorly.

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

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

When it comes to viewing angles, we enter a territory where VA matrix technology dictates inevitable conditions. As expected, this is the weak point of this model. It is enough to move away from the screen's axis to observe a gradual degradation of the image: colors begin to fade, contrast noticeably drops, and black loses its depth. In direct competition with IPS panels, which are renowned for their generosity in this aspect, the VA matrix must concede superiority to its competitor. Is there a plus side to this? Paradoxically, yes. Poor viewing angles are, in fact, the price we consciously pay for the fundamental advantage of this technology – a significantly higher native contrast and deeper blacks when viewed head-on. So, one could say that this is a television that favors the viewer sitting in the "ideal" spot, offering them a maximally vibrant image at the cost of universality.

Viewing angles are unfortunately a weak point of the Hisense U7S. As soon as you move to the side, colors lose saturation, blacks become lighter, and the picture looks washed out. At a 45-degree angle we measured a 74% drop in brightness, so the difference compared with watching head-on is really large. That's a typical limitation of VA panels. When sitting centrally you can appreciate its strong contrast, but people seated at the far ends of a wide couch will see a noticeably weaker 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 has a slight advantage thanks to its satin screen coating. Its structure manages to quite effectively dampen direct reflections, dispersing them and protecting the image from excessive color fading or black brightness. However, passive combat with reflections is one side of the coin. The other is the active ability to "break through" bright surroundings, and here one of the key limitations of this model becomes apparent. The previously mentioned peak brightness of around 300 nits is simply too low to provide a fully comfortable and dynamic viewing experience in a brightly lit living room. In such conditions, the image may lack punch, and lower brightness scenes may lose clarity.

The Hisense U7S performs well for daytime viewing. In SDR we measured an average of about 664 nits, and depending on the screen content the brightness ranged roughly from 500 to 800 nits. Even with an all-white image it stays above 500 nits, so a sports broadcast or a bright TV program won't suddenly look dim. That's enough headroom for comfortable viewing in most living rooms. The satin finish does a decent job of reducing reflections, but a window opposite the TV will still be visible. In the photo you can clearly see that its reflection can obscure part of the picture, so high brightness alone doesn't solve everything. On the plus side, blacks and colors hold up in daylight and don't become excessively gray. Overall the U7S works well in a bright room, though you should position it to avoid direct window reflections.

Smart Features – the Power of Google TV

The heart and brain of the TCL P7K / P79K is the Google TV system, which in itself is a huge advantage. This platform provides access to an almost endless library of applications from the Play Store, ensuring that we won't be missing any key streaming service. Integration with other devices is exemplary – Apple device owners will appreciate the seamless cooperation via AirPlay, while Windows and Android users will easily take advantage of the screen mirroring feature. It is also worth highlighting the Google Assistant, which performs fantastically with voice searches in Polish, 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 "average plus." The interface is mostly smooth, but during testing, it experienced occasional slowdowns and even sporadic "freezes" requiring a moment of patience. Minor hiccups are also visible in the translation of some system messages, which can be awkward – however, these are just small oversights on TCL's part, not affecting overall functionality.

Classic Features

In the age 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, greatly enhancing user comfort. The presence of Bluetooth technology for connecting external devices, like headphones or speakers, should also be noted positively. However, this is where the list of conveniences basically ends. It is evident that TCL has placed nearly everything on the Google TV card, treating classic functions as an absolute minimum. Therefore, we will not find the option to record programs 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 necessary.

Smart TV: VIDAA

VIDAA HOME OS on the Hisense U7S is feature-rich, runs quickly, and doesn’t complicate everyday use. In addition to apps, it supports AirPlay for streaming from Apple devices and Miracast for mirroring a computer display. Voice search in Polish also works, so instead of typing a movie title with the remote you can just say it. You can also connect a keyboard and mouse. In terms of smart features there’s little to complain about, though before buying it’s worth checking the availability of specific apps you use, as it isn’t as extensive as competing systems.

Classic features and the remote

Hisense hasn’t forgotten viewers who watch regular TV. The U7S lets you record over-the-air programs to a USB drive and schedule recordings for later. There’s teletext, the option to listen to audio with the screen off, and support for Bluetooth headphones. Conveniently, headphones can operate at the same time as the TV speakers, so one person, for example a senior, can use them while others still listen normally. The main notable missing feature is picture-in-picture, or PiP.

We weren’t fond of the remote itself. It’s very plastic 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 only 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 puzzling case, putting us in quite an unusual situation. On one hand, its engine handles decoding most popular video formats, which is obviously good news. On the other hand, we encountered a surprising and irritating issue – the default application has a fundamental problem displaying Polish diacritical characters in subtitle files correctly. 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 problem can be easily circumvented. Installing an alternative, advanced player, such as the reliable VLC or KODI, completely resolves this inconvenience. The situation is peculiar because this flaw did not occur in other TCL models we tested previously. We are therefore dealing with a clear software oversight, which, hopefully, will be fixed 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 issues, including high-bitrate 4K recordings and the test Dolby Vision file. SRT and SUB subtitles work, including Polish characters and font color changes. Not everything worked, however. AV1 and H.266/VVC files did not play, nor did ASS and TXT subtitles. Audio is good, from basic MP3s to FLAC 96 kHz/24-bit, though AIFF and DSD are not supported.

Our biggest issues are with photos. Supported formats are extensive: in addition to JPEG and PNG, WebP and TIFF work as well, but HEIC won't open. Resolution handling is also odd. The TV displayed 4, 6, 8, 16 and 32 MP images, but couldn't handle 10, 12 or 24 MP files. So it's not a straightforward size limit. The player is perfectly fine for videos and music, but when showing vacation photos you may find that some files need to be converted 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 dialogues in movies and TV shows are conveyed 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, with a large Onkyo subwoofer at the back of the cabinet, defined the strength of its sound. Here, that element is simply missing, making the sound seem flatter and lacking the depth that creates a cinematic atmosphere. We also noticed a peculiar feature in the software – when trying to set the maximum volume, the TV automatically reduces it. It's hard to conclusively determine whether this is a form of protection against distortion or a minor software bug; nonetheless, it's a pity, as the power reserves seem to be somewhat 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 it correctly displays Polish characters in subtitles. It should be sufficient for everyday use with a USB flash drive, although it can have problems with less common formats. Our biggest issue is with photos. The TV handles their resolution rather selectively: it may open a larger photo but refuse to display a smaller one. When browsing a vacation album this can be annoying, because we can't be sure all the photos will display. Some of them will need to be prepared on a computer beforehand.
