Our verdict

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.

Without a doubt, the LG G6 is an outstanding television in many aspects. Thanks to the new generation 2 Tandem OLED panel, it does something that no other glossy screen on the market has managed so far – it superbly suppresses light reflections while maintaining perfect, unblemished image quality. When we add record brightness and the unique properties of the panel itself, the G6 can produce images that can literally knock you off your feet at times. The excellent webOS system and features for gamers further reinforce the belief that it is a worthy successor to the G5 model. However, this is only one side of the coin... because in a device of this class, the expectations are the highest they can be. During detailed testing, we encountered issues with digital image processing in scenes close to black. We're talking about overly aggressive dithering and slight flickering of details in dark sequences. Although during normal viewing from the couch this flaw does not stand out drastically and does not negate the overall admiration for the contrast, a trained eye will easily notice that LG's engineers stumbled at the last hurdle during the panel tuning. When buying a pretty expensive flagship product right here and now, perfection is simply expected from the first turn on.

Despite this obvious blunder, the LG G6 is still absolutely at the forefront of the market and one of the most interesting televisions of this year. It has a solid foundation to become the ultimate screen. We firmly believe that the manufacturer will quickly diagnose the problem and release an appropriate software update – if that happens, the competition will again have nothing to look for. We promise to keep monitoring the situation continuously, and as soon as a patch appears, we will definitely verify its effectiveness.

Halo effect and black detail visibility:

Check the visibility of bright lights on a dark background. Mini-LEDs often struggle with this. The photo does not compare black levels – that’s what the video below is for.

The video accurately shows differences in contrast and black levels between TVs, as well as potential issues: halo around bright objects or Mini-LED zone operation visible as brightness jumps.

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".

As the LG G6 is based on OLED technology, specifically the WOLED TANDEM 2nd gen matrix, when it comes to black levels and contrast, we’re talking about perfection, which is confirmed by our lab measurements – in every test scenario, the TV achieved an absolute infinity mark. The ability to independently control each pixel gives it a significant advantage over any LCD panel on the market. This translates to a brilliant, plastic depth of image that immediately pulls you into any possible viewing experience. This is clearly visible in the example of a dark, challenging scene with a helicopter from the film Sicario 2. While traditional screens with local dimming (including Mini-LEDs) can generate an annoying “halo” effect in such moments, lighten black bars in films, or lose details in the shadows, the LG G6 handles it flawlessly. Black, where it needs to be black, remains pitch-black and perfectly separated from bright points.

*A small note: during this test, a quite strong grain and flickering of the image are noticeable. However, we do not take this into account when assessing the contrast itself and this part of the review – we will describe this specific issue in the further section. Paragraph: "Smoothness of tonal transitions".

Luminance of RGB colors

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 LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits and, best of all, this translates directly to real movie scenes. The TV flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points in the form of stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 drops due to the panel protection system (ABL). However, in real, varied movie shots, this value still hovers around an impressive 2000 nits, which can be considered a remarkable result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel has brought about only a cosmetic change, but still an improvement. The coverage of the DCI-P3 color space reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although it's important to remember one thing: at extremely high brightness levels, the volume of colors will be lower than in QD-OLED panels from Samsung Display due to the use of white sub-pixels (WOLED). However, in everyday content and most films, capturing this difference will be very difficult.

Factory Mode

After calibration

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.

We tested the LG G6 in the best factory mode for colour fidelity, which is FILMMAKER MODE. In the case of our test unit, this mode was reasonably well tuned straight out of the box. In SDR content, the only issue we noticed was the white balance, which leaned towards warmer tones. This made the image occasionally appear slightly yellowish, but overall, it wasn't a significant problem. The G6 performed a bit worse in HDR content. There, the white balance showed too much blue component. This caused the image to veer towards cooler shades, resulting in quite noticeable errors. As can be seen on our ColorChecker chart, the colours shifted towards these cooler registers. Nevertheless, considering the factory settings, the television presented a perfectly decent level. However, we know that OLED screens – particularly those from LG – respond exceptionally well to professional calibration, so we immediately proceeded to do just that.

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.

After completing a professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We were able to tune the white balance perfectly, which removed the factory's cool and warm tints from the screen. The effects are visibly clear in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does this mean? PERFECT colours, without any distortion! However, as a reviewer’s duty, we must point out how the LG G6 arbitrarily manipulates brightness, which is due to the EOTF curve's behavior. When we look at the standard synthetic graph, it might seem that the line is quite straight. However, the situation changes when we turn on the measurement filter, which shows how the television interprets brightness in actual, moving film scenes (EOTF in MOVIES). Then, it is clear as day that some of the smallest fragments on the screen are slightly overly brightened by the algorithm. Of course, for the average viewer, such a deviation will practically go unnoticed, but in the test of such an expensive screen, it’s worth noting – especially since we are talking about a model that has huge aspirations for the title of the best television of the year.

Smoothness of tonal transitions

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.

Unfortunately, we arrive at the least cheerful part of this review. If we were to evaluate solely the fluidity of tonal transitions, the G6 would score high marks. The blending of colours is at a very good level, and at times it resembles what we've seen from Samsung's QD-OLED panels. This is great news because until now, unsightly, layered bands in dark shades have been the bane of WOLED panels. In this category, we would easily give a strong 8.5 out of 10.

Note: Unfortunately, the final score in this section drops significantly, and the culprit is very aggressive dithering. In dark scenes, the image literally "shakes," and in areas close to black/dark grey, the television can flicker annoyingly. We don’t know exactly what this is due to, but looking at the tests from other reviewers around the world – everyone has encountered exactly the same problem. We hope that LG will fix this as soon as possible with some sort of update. We know that LG is capable of responding quickly to negative user feedback, which can already be read online. We will keep an eye on this and will inform you in case of any improvements.

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.

No matter what one might say about the G6's issues with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content extremely well. All unwanted, ugly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artifacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this feature do further smooth the image, but they start to blur the real texture elements of the objects, so we recommend keeping this slider at a low level. As for the actual upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this respect, the G6 is on par with the global leaders.

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.

The LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The TV supports very high refresh rates of up to 165 Hz in 4K resolution, but most importantly – there are absolutely no signs of blurring on the screen. The response time of the matrix is virtually instant, ensuring that dynamic images remain perfectly sharp.

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 LG G6 is a true beast for gamers and one of the best-equipped TVs on the market in this regard. The manufacturer didn't compromise and equipped this model with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This means that no matter which port you plug in your PlayStation 5, Xbox Series X, or powerful PC, you'll get the absolute maximum performance out of them.

The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), to AMD FreeSync Premium Pro, and Nvidia G-Sync Compatible. Let's add to that a remarkably low, almost imperceptible input lag and an excellently functioning game panel (Game Optimizer), which allows you to constantly monitor signal parameters. Gaming on this screen, with the perfect black of OLED and powerful refresh rates, is pure pleasure.

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.

When it comes to signal delay, the results are remarkably low. With a standard 120 Hz signal, the Input Lag is just 5 ms. At 60 Hz, this value increases to 13 ms, which is still excellent and completely imperceptible latency. The only thing we need to criticise is the TV’s behaviour when providing the Dolby Vision Gaming signal. In this format, the Input Lag nearly doubles, reaching 13 ms for 120 Hz and 22 ms for 60 Hz. Despite this jump, we believe these values in gaming are so low that absolutely no one will feel any discomfort during gameplay.

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.

As we mentioned earlier, the LG G6 offers an outstanding display for gamers as well as for casual computer users. With full support for Nvidia G-Sync and AMD FreeSync technology, as well as a high refresh rate of up to 165 Hz, this television performs brilliantly as a massive gaming monitor. However, daily office work with text looks a bit worse (though in our opinion still very good), which is a typical characteristic of every WOLED-type screen. Due to the specific arrangement of four subpixels (with an additional white subpixel), rather than three like in classic computer monitors, system fonts can have an additional, in this case red glow around black or white letters. This is directly due to the new structure of the second-generation Tandem OLED matrix, which now operates in an RGWB arrangement (last year's first generation Tandem OLED used a BWRG arrangement). In our opinion, the sharpness of font edges has slightly worsened because of this, but it is definitely not something that will immediately catch your eye during occasional document work or web browsing.

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.

As befits an OLED panel, the viewing angles on the LG G6 are really good. A TV viewed from the side does not lose drastically in brightness or colour saturation. In this regard, the image quality is miles better than any LCD TV – and this applies to both IPS panels and especially to VA panels that lack special wide-angle coatings. In this area, the only better screens on the market remain QD-OLED panels from Samsung Display, where the angles are simply perfect, as well as older WOLED panels with MLA (microlens) technology, which LG abandoned in this series two years ago. Unfortunately, we assess the viewing angles in this year's model to be slightly worse than last year. We noticed that the 2nd generation Tandem OLED panel tends to take on a greener hue at a steep angle, while last year's model maintained greater neutrality in this regard.

TCL P7K / P79K: 299 cd/m2

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.

LG G6 will perform wonderfully as a television in a well-lit room. Thanks to its impressive peak brightness, the TV can easily cut through most external light sources. Best of all, the new generation of Tandem OLED panel has brought significant improvements in reducing reflections. Although the screen coating is still glossy (which helps maintain well-saturated colours even in challenging conditions), it effectively dampens glare. It does this far better than traditional OLED screens with a standard glossy coating. We could confidently compare this level to glossy QD-OLED panels, but with one key advantage for LG. Unlike the competition's technology, in this model, deep black in a bright lounge remains intact. There’s no grey or purple tint from ambient light – the black in the G6 during the day is just as perfect as it is at night.

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.

webOS System and Smart Features

The television runs on the latest version of the webOS system. Although it is a closed platform, it supports absolutely all the key streaming apps on the market. You can also easily access useful wireless connectivity features like built-in Chromecast, AirPlay, and classic screen mirroring. However, the biggest standout feature of the LG platform is the brilliant Magic remote. While it is quite compact and lacks a physical numeric keypad, it does something that competitors still can't replicate – it functions like a wireless mouse. It is equipped with a gyroscope, allowing you to move an intuitive cursor across the screen, which dramatically speeds up entering passwords or navigating menus. Additionally, LG has one of the best voice assistants for controlling the device, and this combination with the Magic remote provides excellent capabilities for navigating the system. The only thing that can be quite irritating here is the intrusive ads and sponsored tiles, as LG increasingly clutters the main screen of the system. Despite this, the lack of Google TV is not a detriment to the G6 – considering the smooth operation of webOS, one can confidently say it is even an advantage.

Features for Traditionalists

In terms of traditional television, the LG G6 also performs excellently and does not forget about traditional users. Despite the minimalist remote, it includes a plethora of useful features. The manufacturer did not skip on the PVR function, which allows recording programs from the built-in tuners directly to external USB storage or a hard drive. We also have a smoothly functioning TimeShift for pausing live TV and a recording scheduling option. These features can prove to be a great advantage during the upcoming FIFA World Cup, when matches will be played late in the evening and we may not be able to watch them live. Of course, standard features are also included, such as the ability to connect wireless headphones via Bluetooth.

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 inability to install an external file player (as is the case with systems based on Android) is actually not a problem for the LG G6. The built-in factory player works great and seamlessly supports most audio, video, or photo formats that we provided from our USB drive. However, during testing, we encountered some shortcomings – namely, a rather strange lack of support for subtitles in the popular .txt format. We do believe that this option will soon be available on the G6 with the next software update.

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.

Despite its very flat body, the LG G6 sounds surprisingly good. The manufacturer has managed to pack quite decent speakers under the display that can produce a sound that is fairly “spatial” – if you can even call the limited physical capabilities of the TV that 😉. The sound is clear, has good dynamics, and is flawless for everyday viewing of news programmes or series. The TV also supports the very popular Dolby Atmos spatial audio codec without any issues.

Unfortunately, for the second year in a row, there is no support for the DTS:X format. Be that as it may, it has recently been quite unpopular in streaming services, but a premium TV in terms of price and quality, in our opinion, simply should not limit users regarding audio format support. Additionally, we have to criticise LG for somewhat downgrading the audio menu itself. We missed more advanced settings and predefined sound profiles, which were definitely more abundant in last year's model.
