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.

LG OLED B6 is a very successful continuation of the B series and a TV that makes a lot of sense as a first step into OLED. It doesn’t try to compete with the most expensive models in every respect, but on the key points it still delivers exactly what many people choose this technology for: perfect black, very high contrast and a picture that can simply look spectacular in movies. Much of that is down to the new budget WOLED panel, the OLED SE. Thanks to it, LG’s cheapest OLED is noticeably brighter than a few years ago, and around 800 nits in HDR is a result you can genuinely see when watching. Bright highlights have more punch, the image copes better in demanding scenes, and combined with OLED black levels the overall look can be really impressive. Films and series from streaming platforms, especially those available in Dolby Vision, benefit in particular. That’s when the B6 makes the most of its strengths and can present a picture that will feel like a big step up for someone moving from a typical LCD TV. This is not a model without compromises. Our biggest concern is how the screen handles reflections. The lack of a classic polariser means the TV fares much worse when placed opposite a large window or a strong light source. Reflections are more noticeable than on other WOLED panels, and the black loses some of its character in a bright room. In controlled conditions that won’t be a problem, but for a very bright living room you should approach this purchase with a bit of caution. There’s also a slight disappointment with webOS. The system itself is still very good, with a rich app library, the convenient Magic Remote and basically everything you’d expect from a modern Smart TV. The problem is that on the B6 it doesn’t always run as smoothly as it should. At times you can feel the new version of the system is more demanding and a bit 'heavier' than before. Despite these remarks, the LG B6 still performs very well. It delivers all the main advantages of OLED while not costing as much as the higher series. It makes the most sense when it appears in a good deal, because then it can become one of the most interesting choices for people who want to step into the world of OLED without overpaying.

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".

The blacks on the LG OLED B6 are perfect. It's no surprise, since it's an OLED (WOLED), but this is where you can really see why the technology still has so many fans. Each pixel can switch off individually, so in dark scenes there’s no grey glow or blooming around bright elements. That gives the picture excellent depth and can make it look truly three-dimensional. Shadow detail also holds up well. Nothing blends into a single dark blotch, and fine elements remain visible even in tougher scenes. In that respect the B6 simply delivers everything we love about OLED TVs.

TCL P7K / P79K

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%.

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

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 B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

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.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED model.

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.

Tonal transitions in the LG B6 are quite good, though some limitations typical of WOLED panels are still apparent. In most scenes colours shift between shades smoothly, without obvious banding or unwanted digital artefacts. It is not always perfect, however. The most problems occur in the darker areas of the image, where WOLED panels have for years tended to perform a little worse. This is partly due to the greater difficulty of driving the panel at very low brightness and to the specifics of a design that uses a white subpixel. Compared with last year’s model there is a slight improvement, but it still is not at the level of the best QD-OLED TVs or more advanced LCD models.

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.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

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.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

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.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.

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.

Input lag on the LG B6 is very low. At 120 Hz it's about 5 ms, and at 60 Hz it rises to roughly 15 ms. Both results are good enough that most gamers won't notice any delay between their inputs and what happens on screen. Dolby Vision performs a bit worse, with input lag sometimes increasing to around 25 ms. It's still not a bad result, but the most demanding gamers using an Xbox may already notice a difference compared with regular HDR.

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.

The LG B6 also works very well as a computer display. Low input lag, support for VRR, G-Sync and FreeSync, and a high refresh rate mean there’s little to criticise when it comes to gaming. Compared with pricier models it only lacks extra modes with even higher refresh rates. In the best OLEDs and some LCD TVs you can now find 240 or even 330 Hz at lower resolutions. The B6 doesn’t offer that, but for most people it won’t be a major loss.

A more important consideration may be the WOLED panel’s subpixel structure. Because it uses four subpixels, small text in Windows isn’t perfectly crisp and you can sometimes see slight coloured fringing. For occasional web browsing or general computer work this is unlikely to be a problem. However, if someone plans to buy a smaller variant — for example a 48-inch model — and use it as their main monitor on the desk, they should bear that in mind.

Moving on to the issue of viewing angles, we enter a realm where VA matrix technology dictates unavoidable conditions. As expected, this is the weak point of this model. It is enough to step away from the screen axis to observe a gradual degradation of the image: colours begin to fade, contrast noticeably drops, and blacks lose their depth. In direct confrontation with IPS panels, which are renowned for their generosity in this aspect, the VA matrix must concede superiority to its competitor. Is there a silver lining? Paradoxically, yes. Weak viewing angles are indeed the price we consciously pay for the fundamental advantage of this technology – a significantly higher native contrast and deeper blacks viewed head-on. Thus, we can say that this is a television that favours the viewer sitting in the “ideal” spot, offering them a maximally vivid image at the cost of universality.

Viewing angles on the LG B6 are very good, which is typical for almost all OLED TVs. Even when watching from well off to the side, the image retains high colour saturation and doesn't noticeably lose brightness. In that respect, only models with QD-OLED panels really perform better. There is, however, one thing worth mentioning. Some WOLED panels can show a slight greenish tint at steep viewing angles. It's not a rule; some units show this effect more, others hardly at all. It comes down to the individual unit.

LG OLED B6: 313 cd/m2

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.

With the LG B6, one of the bigger changes comes from the new OLED SE panel. The TV is slightly brighter than its predecessor, but at the same time handles direct reflections worse. The reason is a less effective polariser, so reflections from windows or lamps are less suppressed and blacks in a bright room can look slightly lifted. LG tried to partly mask this effect with a satin screen coating. It does help to gently diffuse reflections, but it doesn't eliminate them as effectively as solutions used previously. And in that respect the B series loses the most compared with the previous generation. During the day the screen no longer looks as clean, and strong light sources can clearly reflect off the panel.

That doesn't mean, of course, that the B6 isn't suitable for a bright living room. The higher screen brightness helps cut through ambient light and during normal viewing the picture remains easy to see. The problem starts when there's a large window or a strong lamp opposite the TV. In those conditions the B6 doesn't cope well. It's therefore best used in a room where you can at least partially control the light falling directly on the screen.

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.

SmartTV: webOS

LG B6 uses webOS, LG’s proprietary platform. Its biggest advantage remains the control method. The included Magic Remote works like a mouse. Just move your wrist to move the cursor across the screen and point at items that interest you. At first it may seem unusual, but it quickly proves very convenient, especially when entering text, selecting apps or navigating a complex menu. The remote itself is quite minimalist and doesn't offer many traditional buttons, but the cursor control largely makes up for that. On the other hand, if you don't want to wave your hand to enter letters, you can simply speak the desired phrase to the remote and the AI voice assistant will provide suitable recommendations.

In terms of available apps, it's hard to fault webOS. You'll find practically all the major streaming services here, as well as extras such as AirPlay, screen mirroring and Chromecast. The TV therefore works well with both Apple phones and Android devices. It's just a pity the system doesn't run on the B6 as smoothly as on higher-tier models. At times it can respond with a slight delay, and the home screen is overloaded with recommendations, tiles and ads. That doesn't make webOS unusable, but it could certainly be more organised.

Classic features

The classic TV features, which many manufacturers are slowly beginning to forget, perform very well. The LG B6 allows, among other things, recording programmes to a connected drive or USB stick. The PVR function also works with a scheduler, so a recording can be planned in advance from the TV guide. This is handy when you want to save an episode, a match or another event broadcast while you're away. There's also a clear channel guide and smooth support for terrestrial, cable and satellite TV. For those who still regularly watch traditional television, the B6 is therefore a relatively complete device, as long as the absence of teletext isn't an issue.

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 LG B6’s built-in player handles most common video files played from USB without any major problems. The TV also correctly supports subtitles and the usual audio formats, although it lacks DTS support. Photo handling is a bit worse. The list of supported formats is fairly limited and does not include HEIC, the format in which photos taken on an iPhone are stored by default. Those files therefore need to be converted to JPG beforehand or you can simply use the AirPlay feature.

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.

In terms of sound the LG B6 performs very similarly to last year’s model. It still has a 2.0-channel, 20 W system that is more than enough for everyday viewing. Dialogue is clear and the audio isn’t bad, but there’s none of the soundstage, dynamics or bass you get from higher-end models. The TV supports the Dolby Atmos spatial audio format, but DTS:X is missing. The biggest issue, however, isn’t the speakers themselves but the settings. Compared with its predecessor many of the options that let you tailor the sound to your preferences have gone. A few preset modes remain, including AI and Standard, but customisation options are much more limited than they were a year ago.
