Compare TCL P7K / P79K vs TCL C7L

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.

The TCL C7L is an incredibly successful Mini-LED television and a fully deserved successor to the hit model C7K. The list of advantages of this device is truly long. At the top is the extremely high brightness of the panel. Thanks to this, the television effortlessly handles brightly lit living rooms, offering an exceptional and dynamic picture in HDR format. Huge praise is also due for the use of the new Super QLED coating – after professional calibration, the colors can be not only natural but also incredibly saturated. The best part is that the screen does this regardless of what scene is being displayed, which is often not the case with all TVs that have RGB backlighting. The C7L is also a great piece of equipment for gamers; you could say it’s a true "media powerhouse." We get full support for consoles and PCs, a refresh rate of up to 288 Hz, G-Sync, and low input lag that doesn’t increase even when the very demanding mode of Dolby Vision Gaming is activated. The whole thing is tied together by a well-optimized Google TV system, which in this generation of TCL devices operates noticeably smoother and more efficiently (at least that’s the impression we got during our tests). Of course, the C7L is not a perfect device, and the manufacturer had to make certain compromises with this model. The biggest drawback of the C7L is the use of a less powerful image processor. Unfortunately, this translates to quite average digital processing and other design limitations in the form of only two HDMI 2.1 ports. A more powerful chip has been reserved this year for higher series, such as the C8L. From a business perspective, this is fully understandable. Why? Because if TCL had put a better processor here, most people would probably see no point in paying extra for the higher model. So even if certain compromises exist, the C7L series once again promises to be one of the most cost-effective Mini-LED televisions this year. If you are looking for a versatile, extremely bright screen for movies, series, television, or games – literally for everything – and at the same time do not want to overpay for the top series, then yes... the C7L is a brilliant choice that we can definitely recommend to you.

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".

TCL C7L is a Mini LED TV, which in the 65-inch variant we tested, is equipped with over 1000 local dimming zones. This, combined with a proprietary VA panel (referred to by TCL CSOT as HVA 2.0), delivers really decent results in terms of black levels and contrast. In most of the scenes we measured, black levels and contrast looked really good, and in the easiest shots, the black was deep enough to resemble that known from OLED screens. We are, of course, talking about the least demanding shots with a lot of black on the screen. However, when a larger number of bright elements appear on the screen, and black no longer dominates so strongly, it becomes clear that the TCL C7L – like most Mini LED TVs – has its issues with managing local dimming zones.

This is particularly evident in the standard black bars in movies recorded in the panoramic format 2.35:1. In this case, a clear halo effect, or bright light glow, can appear on the black bars or around small, bright objects. The contrast then drastically drops – from laboratory values of around 200,000:1 to about 10,000:1, which is quite noticeable in a completely dark room. It is worth remembering that this should not be treated as a flaw of the TV but rather as a characteristic of mini-LED technology. Of course, this effect becomes much less bothersome when we turn on at least some soft, diffused light in the room... which I definitely recommend doing during viewing sessions on any LCD TV.

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%.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness levels of around 2800 nits. This is an absolutely phenomenal result, considering the price range it falls into. Unfortunately, the tests with real film scenes are not as spectacular as the measurements of white squares. The brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as the vast majority of contemporary films are mastered at such a value. However, when small, pinpoint elements appear on the screen, the brightness of those details drastically drops – even to about 400 nits – which diminishes the HDR effect somewhat. The television does this intentionally to maintain a better level of black and prevent a huge glare of light. This is somewhat explainable, but it also shows that Mini LED technology is not completely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colors are obviously key here. And these, thanks to the use of new, "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve around 90% coverage of the ultra-wide color gamut BT.2020 and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such high color saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED televisions.

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.

When it comes to colors straight out of the box, a new feature in TCL televisions – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was previously unavailable from this manufacturer. By design, as the name itself suggests, the image in this setting is intended to be presented with the full intent of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful color reproduction straight out of the box. However, we definitely wouldn't say that it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode strayed into a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue color. Of course, for the average viewer, this may not be a drastic flaw, but if you care about perfect whites, natural skin tones, and fully unlocking the potential of these new "super" quantum dots, this television is in need of professional 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.

After conducting a professional calibration, we managed to significantly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide color gamut dropped below the threshold of human perception – that is, below a value of 3, which is indeed a very good result. The TCL C7L definitely benefits from such an intervention in terms of color fidelity, and it's hard to dispute that. However, the management of brightness in HDR content post-calibration looks a bit worse. As I described earlier – even though we set up this model properly, when we turn on actual film scenes on the TV, it manages its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which is clearly visible in the EOTF graphs measured in specific films. Despite this defect – or rather a specific characteristic of this television – one cannot take away from it that after calibration, the C7L was able to reproduce the colors completely accurately.

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.

Another element worth discussing is the fluidity of tonal transitions. Here, it's fair to admit that in the TCL C7L, it simply looks good. In most scenes – especially in the brighter shots – there are absolutely no issues with gradients. In native 4K HDR content, the picture is clear, and the transitions between shades are very smooth. It looks just as good in Dolby Vision mode, where we did not notice any digital defects or unpleasant color banding during testing. One could nitpick very dark shots where a heavily compressed signal is displayed on the screen. In such conditions, the C7L can sometimes show minor imperfections; however, in this model, it's not something that stands out too much. Especially during regular movie viewings.

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.

This point can be, in a sense, called the Achilles' heel of the C7L model. Unfortunately, this TV uses an older MediaTek chipset – the Pentonic 700 – which has never been known for exceptional digital image processing. This is clearly evident in the operation of the gradual smoothing feature, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – after setting it to low, its effectiveness is practically nonexistent. The only small plus here is that the algorithm doesn't spoil anything additional in the image and doesn’t forcibly blur details. The upscaling, that is, scaling the image from lower resolutions to 4K, performs a bit better. It is simply adequate and doesn’t stand out in any particular way compared to the competition. However, it cannot be denied that the C7L would gain significantly in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now increasingly found in many competitive models.

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.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which can even ramp up to 288 Hz at lower resolutions when using a PC. These are, of course, very high values and commendable on paper, but in everyday life, it's worth remembering that nearly all dynamic content you display on this television will still be running around a maximum of 120 Hz. To harness this dynamics, we find a motion smoothing system in the TV's menu called “Motion Clarity.” It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-true guides on our YouTube channel. There we have two key sliders at our disposal. The first one, “Blur Reduction,” is responsible for reducing blurring and improving sharpness in dynamic 60fps materials, such as sports broadcasts. The second slider, “Flicker Reduction,” allows for the addition of artificial frames in movies and series recorded at cinematic 24 or 30 frames per second. This, of course, completely eliminates the irritating stutter effect during camera movement shots.

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.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, we have access to all the key features that console owners and powerful PC users require. It offers a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates impressively from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a well-designed gaming panel, the Game Bar, which even allows for customization of its appearance and theme to perfectly match the aesthetics of your console.

The only thing that can – and indeed must – be criticized here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home theater system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you will have to give up something or constantly juggle the cables at the back of the unit while maintaining convenient audio system control.

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.

It is worth taking a look at the dry numbers here, because in terms of signal delay, the TCL C7L is absolutely at the top of the market. Our measurements showed that the input lag is extremely low and for a 60 Hz signal it is only about 10 ms. When we step up to a higher level and launch a game at 120 Hz, the delay drops to an imperceptible 6 to 7 ms. However, what is more important is that these values are maintained even after activating the Dolby Vision format in games.

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 it comes to gaming on PC, as I mentioned earlier, it is truly seamless. The TV effortlessly supports high refresh rates: full 4K at 144 Hz, and at Full HD resolution, it can even ramp up to 288 Hz. Moreover, both G-Sync and FreeSync synchronization systems work here without any issues. For PC gamers, the C7L can serve as an excellent, gigantic monitor.

However, typical office work with text looks a bit worse, all due to the panel behaving quite strangely under these conditions. When the highest refresh modes are turned on, namely 144 Hz and 288 Hz, the readability and sharpness of dark text on a light background is rather average – fonts become slightly blurry and jagged. Fortunately, this can be very easily fixed by changing the refresh rate in the graphics card settings to a stable 120 Hz. Then the text becomes perfectly sharp again, which is definitely worth remembering if you plan to use the C7L as a work screen.

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.

Unfortunately, the powerful native contrast of the HVA 2.0 panel comes with a price. It concerns the viewing angles, which in the C7L model are simply poor. This is all, of course, due to the use of the aforementioned VA panel. It is a completely natural characteristic of this technology and something to be aware of when making a purchase. If you sit directly in front of the screen, the picture will impress you with its depth, but just shifting a few dozen degrees to the side on the couch will cause the colors to immediately begin to fade. By choosing this model, you are opting for a classic market compromise: you get brilliant black and fantastic contrast, but you lose out on viewing angles.

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.

It is also worth mentioning how the TCL C7L performs during everyday viewing in a sunlit living room. As we have established, this is an extremely bright television, and it is precisely because of such a powerful supply of luminance (up to 2400 nits in SDR!) that it manages to perform exceptionally well in very bright rooms – the image simply pushes through the incoming light into the room without any problems. The only thing to watch out for here is direct reflections on the screen. The coating applied to the panel this year is definitely glossier than the one we saw in last year’s C7K model. The screen significantly worsens the suppression of point light reflections, which in unfavorable conditions – for example, when a window is positioned directly opposite the television – can be quite irritating for some users. Nevertheless, in terms of raw brightness, the C7L is simply a demon for bright living rooms.

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.

Google TV and Smart TV

The multimedia heart of the TCL C7L is, of course, the Google TV operating system, which provides access to a massive library of apps and all the most popular streaming platforms on the market. The Smart TV in this model works seamlessly, offering full support for useful network features such as Apple AirPlay and Chromecast. However, a huge and very pleasant surprise is the overall performance of the software. We noticed that Google's system on the new C7L operates much more efficiently, smoothly, and quickly than on TCL models from last year. Much of this is due to better optimization at launch. Unnecessary pauses and minor interface hiccups, known from older models, seem to have faded into oblivion.

TV Features

In terms of classic antenna or cable television, the TCL C7L does not offer many additional, advanced features. It is simply a straightforward receiver. The manufacturer did not strive for any revolutionary solutions here, so apart from the traditional program guide, you won’t find anything special. A significant nod to traditional viewers is the classic remote control, which, contrary to the current trend towards minimalism, is still equipped with a full numeric keypad, greatly facilitating quick channel switching.

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.

Finally, it's worth mentioning the playback of files from external USB drives in the multimedia section. During our tests, we didn't notice any unpleasant surprises here – the factory player handles all popular video and audio formats exactly as it should. Interestingly, the TCL C7L also played photos saved in Apple's native format, HEIC, without any issues. This is an extremely rare feature in manufacturers' factory applications. And while the Google TV system gives you unlimited options for installing external media player programs, in the case of the C7L, the built-in tool is refined enough that installing additional software is unlikely to be necessary for anyone.

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.

TCL C7L simply performs quite well and correctly. In terms of sound quality, there has practically been no change compared to last year's model C7K. The manufacturer still uses a speaker system branded with Bang & Olufsen in a 2.2 setup. The only thing that can be quite irritating during viewing sessions is the fact that after increasing the volume to higher levels – around above 50% on the scale – the volume stops correlating with the scale visible on the screen. The audio system from B&O works great for daily watching of news programs or series at moderate volume, but if you're looking for good sound, it's worth buying at least a basic soundbar for the C7L.
