Our verdict

iFFALCON U85X is a device that draws heavily from the technological solutions of its parent brand, TCL. It's hard not to get the impression that, in terms of pure technical specifications, we are dealing with almost a faithful copy of the successful C6K (C69K/Q6C) series, although in terms of design, the designers opted for references to the more budget-friendly P line. This specific combination makes the television do exactly what we expect from a solid Mini-LED, but at an even lower price. It provides very good contrast and a vivid HDR effect, which is directly due to the impressive number of local dimming zones. It is worth noting that, like the models from the C series, iFFALCON U85X turns out to be exceptionally tailored to the needs of gamers. Here we find almost every function necessary for comfortable gameplay, from full support for HDMI 2.1 ports, through ALLM and VRR technologies for console owners, to remarkable compatibility with PCs. As a monitor, the device performs excellently not only due to its support for refresh rates up to 240Hz but also because of the very sharp and readable font, which is not always a given in the world of televisions. Of course, this is not an ideal model, as it shares the same set of advantages and disadvantages as its TCL counterpart – mainly referring to issues like noticeable ghosting or aggressive brightness management in HDR. However, it creates an exceptionally interesting mix that makes us seriously question the sense of the existence of the iFFALCON brand as a separate entity, since the same product could successfully debut with the full TCL logo on the casing. Nonetheless, we have no major objections to the device itself; it is truly a model worth considering, provided you manage to buy it, as it is currently very difficult to obtain.

Without a doubt, the LG G6 is an outstanding television in many respects. Thanks to the new second-generation Tandem OLED panel, it does something that no other screen with a glossy coating on the market has been able to achieve – it superbly suppresses light reflections while maintaining perfect, unblemished picture quality. When we add to this its record brightness and the unique properties of the panel itself, the G6 can generate images that can literally take your breath away at times. The excellent webOS system and features for gamers only reinforce the belief that this is a worthy successor to the G5 model. However, this is just one side of the coin... because with a device of this class, the expectations are the highest possible. During detailed testing, we encountered a problem with digital image processing in scenes close to black. There was too aggressive dithering and slight flickering of details in dark sequences. While this flaw does not stand out drastically during normal viewing from the couch and does not undermine the overall admiration for the contrast, a trained eye will easily notice that LG's engineers stumbled at the final hurdle while tuning the panel. When purchasing a fairly expensive flagship product here and now, perfection is simply expected from the first power-up.

Despite this evident slip-up, the LG G6 is still at the absolute forefront of the market and one of the most interesting televisions of the year. It has solid foundations 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 once again have nothing to look for. We promise to monitor the situation continuously, and as soon as a patch is released, we will certainly 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 terms of blacks and contrast, the 65-inch iFFALCON U85X turns out to be almost an exact copy of the solutions known from the TCL C6K and C69K models, offering the same number of 224 local dimming zones in a 14x16 arrangement. Thanks to the use of a VA panel and such a solid number of zones, the device is capable of generating an image with impressive depth, where our measurements in real film scenes indicated a contrast exceeding 100,000:1. Of course, with this class of equipment, local dimming does not always achieve perfect precision, so in more challenging scenes with bright details against a dark background, we must reckon with the occurrence of the halo effect, which is a subtle glow around objects. Nevertheless, the overall quality of blacks is at a very high level and will certainly satisfy most users seeking cinematic experiences. The image certainly appears to have greater depth than in solutions without any local dimming technology.

As the LG G6 is based on OLED technology, specifically the 2nd generation WOLED TANDEM matrix, when it comes to black levels and contrast, we are talking perfection, as confirmed by our laboratory measurements – in every test scenario, the television achieved an absolute infinity score. The ability to independently control each pixel gives it a significant advantage over any LCD panel on the market. This translates into a brilliant, plastic depth of image that immediately draws you into every possible viewing experience. This is perfectly illustrated by the example of a dark, demanding scene with a helicopter from the film Sicario 2. While traditional screens with local dimming (including Mini-LEDs) can generate an irritating “halo” effect during such moments, brighten black bars in films, or lose details in shadows, the LG G6 performs 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 noticeable graininess and flicker of the image stands out. However, we do not take this into account in the assessment of the contrast itself and this part of the review – we will describe this specific problem in the following section. Paragraph: "Smoothness of tonal transitions".

IFFALCON U85X

Luminance of RGB colors

iFFALCON U85 handles HDR in a rather twofold manner – on one hand, it can surprise with solid peak brightness of around 650 nits, which places it well above average in this price segment. This is especially evident in bright, full-screen scenes. Examples from films such as Life of Pi or the final test sequences from The Meg prove that the television can maintain the power and essence of HDR effect when the entire panel needs to "ignite," delivering truly satisfying experiences. However, problems arise in high-contrast scenes, where smaller, bright details appear on the screen; the dimming algorithms prioritize black depth to such an extent that they can stifle the brightness of small light points to just 100 nits, which drastically reduces image dynamics and deprives us of the true "bite" we expect from HDR standards. On a brighter note, however, the colours remain impressive, as the use of the PFS phosphor filter (marketed as QLED by the manufacturer) showcases them very well, achieving nearly 94% coverage of the DCI-P3 colour palette, allowing for a vibrant and rich image in most content.

The LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits, and what’s best – this has a direct impact on real film scenes. The television flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points like stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 decreases due to the panel protection system (ABL). However, in real, varied cinematic shots, this value still hovers around 2000 nits, which can be considered an outstanding result. The coverage of the colour palette also deserves praise. The new second-generation Tandem OLED panel only brought a cosmetic change but still an improvement. The coverage of the DCI-P3 palette reaches nearly 99.5%, whereas for the ultra-wide BT.2020, it is around 84%. These are very good results, although it’s worth remembering one thing: at extremely high brightness levels, the colour volume will be lower than in Samsung Display’s QD-OLED panels due to the use of a white sub-pixel (WOLED). However, in everyday content and most films, catching this difference will be very difficult.

Factory Mode

After calibration

We tested the factory colours on the iFFALCON U85X model in 'Film' mode, which is definitely the most reliable among all available settings, although it is still far from perfect. The main issue that stands out in both SDR and HDR content is the incorrect white balance – an excess of blue and red components gives the image a slight purple tint, which disrupts the naturalness of the film scenes. An even greater challenge is the way the television manages its brightness. Analyzing the gamma chart for the SDR signal, we noticed significant instability: instead of adhering to the standard value of 2.4, the device oscillates around 2.2, only to suddenly make an unnatural jump towards 3.0. In practice, this leads to confusing effects – large, bright areas on the screen appear too dark, while smaller elements are unnecessarily brightened. A similar characteristic can be found in the EOTF curve, which makes the image unpredictable and loses its cinematic authenticity.

We tested the LG G6 in the best factory mode in terms of colour fidelity, namely FILMMAKER MODE. In the case of our test unit, this mode was quite well tuned straight out of the box. In SDR content, the only issue we could point out was the white balance, which tended to drift towards warmer tones. Consequently, the image could occasionally appear slightly yellowed; however, overall, this was not an bothersome problem. The G6 performed a bit worse with HDR content. There, we noted too much blue component in the white balance, which caused the image to take on cooler hues, resulting in fairly noticeable errors. As can be seen in our ColorChecker chart, the colours indeed drifted towards these cooler registers. Nevertheless, considering the factory settings, the television displayed a perfectly decent level. We do know, however, that OLED screens – particularly those from LG – respond excellently to professional calibration, which is why we immediately went ahead with it.

After professional calibration of the movie mode, we must admit that the result is more than satisfactory – the iFFALCON U85X undergoes a true transformation. Colour errors in SDR content have dropped to a level below 2, which makes them virtually imperceptible to the human eye. We have managed to set the white balance almost perfectly, and brightness management (gamma) has become nearly exemplary. As a result, with standard quality materials, the television simply looks perfect and it is difficult to fault it.

In the case of HDR signal, the situation has also significantly improved, although here the nature of the device becomes a bit more evident. Colour errors have been reduced to around 3, which is an outstanding result in this price range. However, it is worth taking a look at the EOTF graph (available on the right side of the screen in the filters: 4K HDR, gamma / EOTF) to notice what is not immediately visible regarding the brightness management by the U85. Although the reference line looks decent, in real film scenes, the television still interprets the signal “in its own way” due to very aggressive local dimming algorithms. Does this disqualify this model for watching HDR content? Absolutely not. It's simply a typical affliction of almost every Mini-LED, which must reconcile high brightness with the attempt to maintain deep blacks. One simply needs to be aware of these technical limitations, which are unavoidable in this segment.

After professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We successfully calibrated the white balance perfectly, which eliminated the factory cool and warm tints from the screen. The effects are clear as day in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does that mean? PERFECT colours, without any distortion! However, as reviewers, we must point out here how the LG G6 arbitrarily manipulates brightness, for which the EOTF curve is responsible. When looking at the standard synthetic chart, 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 real, moving film scenes (EOTF in MOVIES). Then it becomes evident that some of the tiniest parts on the screen are slightly over-brightened by the algorithm. Of course, for the average viewer, such a deviation will be practically unnoticeable, but in the test of such an expensive screen, it is worth noting – especially since we are talking about a model that has huge aspirations to be named the best television of the year.

Smoothness of tonal transitions

In terms of fluidity of tonal transitions, the iFFALCON U85X performs quite decently. In most scenes, the gradients are almost imperceptible, so the annoying "banding" of colours should not be noticeable during daily viewing, for example, on choose.tv. However, it must be honestly admitted that in very dark shots, the image is not always perfectly smooth, and certain imperfections in the transitions between shades can be observed. Nevertheless, this result is more than satisfactory and does not spoil the overall perception of the picture.

Here, unfortunately, we come to the least cheerful part of this review. If we were judging solely the fluidity of tonal transitions, the G6 would receive high marks. The blending of colours is at a very good level, and at times it resembles what we know from Samsung's QD-OLED panels. This is great news, as until now, ugly, layered bands in dark shades have been the bane of WOLED panels. In this category, we could easily give a strong 8.5 out of 10.

Note: Unfortunately, the final rating in this section drops significantly, and the culprit is very aggressive dithering. In dark scenes, the image literally 'trembles', and in areas close to black/dark grey, the television can irritably flicker. We do not know exactly what causes this, but looking at the tests of other reviewers around the world – everyone has encountered exactly this same problem. We hope that LG will fix this as soon as possible with some update. We know that LG can respond quickly to negative user feedback, which can already be read online. We will monitor the situation closely and will inform you in case of improvement.

Image scaling SD (576i)

The model photo shows how it handles upscaling of SD material.

When it comes to upscaling the image to 4K resolution, the iFFALCON U85X performs well. The device efficiently enhances low-quality signals, making even older materials look clean and clear on the 4K panel. At extremely low resolutions, such as 480p, one can notice slightly jagged edges (especially on fine lines), but let's be honest – this is a scenario that you will encounter only when watching very old recordings, so in everyday use, it is not a real problem.

Much worse is the digital processing aimed at smoothing tonal transitions. Although in the menu we find the “Gradual Smoothing” function, its effectiveness is at least questionable. In practice, it does not effectively eliminate banding (colour banding), and worse, it can cause more harm than good. This filter can be too aggressive in areas where it shouldn’t, artificially smoothing details that should not be altered, such as the natural texture of the face or fine details of skin texture. Instead of improving quality, this function can give the image an unnatural, “plastic” appearance, so it is best to use it with great caution or, preferably, leave it switched off.

Whatever one may say about the G6’s problems with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content exceptionally well. All unwanted, unsightly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artefacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this function do indeed smooth the image further, but they start to blur the real elements of object texture, which is why we recommend keeping this slider at a low setting. As for the upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this regard, the G6 does not fall behind the world leaders at all.

In contrast to budget constructions, which in dynamic sports scenes can resemble a slideshow, the iFFALCON U85X is a heavyweight contender equipped with a panel that has a native refresh rate of 144Hz. However, it is worth noting that in the world of films, series, or sports, we will primarily operate at 120Hz due to the specifics of how image enhancement systems function. Such a fast panel is excellent news for gamers and sports fans as it opens the door to advanced motion settings that simply do not exist in cheaper 60Hz models.

We manage everything from the menu “Motion Clarity”, where instead of using pre-set, often overly aggressive modes, we definitely recommend our own configuration based on two sliders. The most important of these, motion blur reduction, is responsible for fluidity in films – here, it’s best to aim for a value of around 4, which will maintain a natural, cinematic character of motion without falling into the artificial “soap opera effect.” Meanwhile, the first slider, motion blur reduction, is the key to success in sports broadcasts. In this case, it’s worth going all out and setting it to maximum, ensuring that the image during fast actions on the field remains sharp, while troublesome trailing is eliminated.

LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The television supports very high refresh rates reaching up to 165 Hz in 4K resolution, but most importantly – on the screen, you will not notice any signs of blurring. The response time of the panel is almost instantaneous, ensuring that dynamic images remain perfectly sharp.

iFFALCON U85X is an outstanding piece of equipment for gamers that has just about everything one can expect from a modern screen for consoles or PCs. We find here two full-fledged HDMI 2.1 ports with full bandwidth of 48 Gbps, which opens the door to key technologies such as VRR and ALLM, ensuring smooth gameplay without tearing the image and with minimal latency. The television handles high refresh rates in various resolutions without any problems, and a real curiosity is the mode that allows for achieving up to 240Hz when dropping down to Full HD quality. The whole thing is managed by the Game Bar (which is a faithful copy from TCL), allowing for instant switching of picture modes, customising the interface appearance, or even adding a virtual crosshair in the middle of the screen.

The LG G6 is a true monster for gamers and one of the best-equipped televisions on the market in this regard. The manufacturer has not skimped on features, equipping this model with as many as 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 will get the absolute maximum performance from them.

The television supports a full set of gaming technologies: from VRR (Variable Refresh Rate) to AMD FreeSync Premium Pro, and even Nvidia G-Sync Compatible. On top of that, it offers remarkably low, nearly imperceptible input lag and an exceptionally well-functioning Game Optimizer panel, which allows you to monitor signal parameters in real time. Gaming on this screen, with the perfect black of OLED and impressive refresh rates, is pure pleasure.

The completed gaming arsenal is complemented by the outstanding latency results we measured in our tests. With a standard 60Hz signal, the input lag is just 17 ms, which is a completely safe value for comfortable gameplay, while switching to 120Hz reduces the latency to an impressive 9 ms. A nice fact is that these excellent parameters do not deteriorate even in Dolby Vision mode. In many televisions, activating this format is still associated with additional processor overhead and increased lag, but here the engineers at TCL (or iFFALCON) have done a great job.

When it comes to signal delay, the results are fabulously low. For a standard 120 Hz signal, the Input Lag is just 5 ms. At 60 Hz, this value increases to 13 ms, which is still an excellent and completely imperceptible delay. The only thing we need to nitpick is the television's performance when using the Dolby Vision Game 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 that these values in games are low enough that absolutely no one will feel any discomfort during gameplay.

The photo shows the legibility of small fonts. Ideally, lines should be the same thickness on both light and dark text, with minimal pixel gaps.

iFFALCON U85X is also an excellent candidate for a powerful computer monitor, offering a work culture that is hard to find in typical televisions. The readability of fonts is nearly exemplary – although due to the nature of the VA panel, it is not as crystal clear as in IPS panels, the difference becomes practically imperceptible to the human eye when viewed from a distance of over one metre. The device natively supports a resolution of 4K at 144Hz refresh rate, but the real ace up its sleeve is the 240Hz mode (available at lower resolutions), which makes this behemoth an excellent tool for dynamic e-sports titles, where refresh rate takes precedence over pixel count. What is almost most important for PC users is that such high performance is fully supported by frame synchronization technologies, such as NVIDIA G-Sync and AMD FreeSync, effectively eliminating screen tearing and ensuring perfect fluidity regardless of the graphics card used.

As we mentioned earlier, the LG G6 is an outstanding screen for gamers as well as those using computers. With full support for Nvidia G-Sync and AMD FreeSync technology, and a high refresh rate of up to 165 Hz, this television performs brilliantly as a gigantic gaming monitor. However, when it comes to everyday office work with text, it does somewhat less well (though in our opinion still very well), which is, by the way, a typical feature of any WOLED-type screen. Due to the specific arrangement of four subpixels (with an additional white subpixel), rather than three as in traditional computer monitors, system fonts can have an additional red halo around black or white letters. This is a direct result of the new structure of the second-generation Tandem OLED matrix, which now operates in the RGWB configuration (in last year's first generation of Tandem OLED, it was in the BWRG configuration). In our opinion, the sharpness of font edges has slightly deteriorated because of this, but it is certainly not something that will immediately catch your eye when occasionally working with documents or browsing the web.

When it comes to viewing angles, the iFFALCON U85X does not surprise us – it is simply poor, which is a typical characteristic of VA panels. We must treat this as a natural and conscious compromise: by choosing a panel with high contrast and deep blacks, we almost always sacrifice wide angles (only in top series do manufacturers use special coatings to improve this feature). You cannot cheat physics in this price segment, because while sitting directly in front of the television the picture looks fantastic, a slight lean to the side is enough for the colours to start losing their saturation. If you are planning evening screenings with a larger group, it is worth ensuring that everyone sits as close as possible to the central axis of the screen.

As is fitting for an OLED panel, the viewing angles on the LG G6 are really good. The television viewed from the side does not drastically lose brightness or colour saturation. In this respect, the picture quality is miles better than any LCD television – and this is true for both IPS panels and even more so for VA panels without special wide-angle coatings. In this area, the only better screens on the market remain the QD-OLED panels from Samsung Display, where the angles are simply perfect, as well as older WOLED panels with MLA (micro-lens array) technology, which LG abandoned in this series two years ago. Unfortunately, we assess the viewing angles of this year's model to be slightly worse than last year's. We noticed that the 2nd generation Tandem OLED panel tends to take on more greenish hues at large angles, while last year's model maintained greater neutrality in this regard.

LG OLED G6 (G64LW, G66LS): 857 cd/m2

IFFALCON U85X: 419 cd/m2

In a bright room, the iFFALCON U85X performs moderately well, thanks to the satin coating of the panel. It quite effectively dampens direct light reflections, thereby avoiding the annoying mirror effect, although under stronger lighting one can see characteristic warm "spills" of light around reflecting objects. While it doesn't reach the level of top panels with the most advanced filters, the lack of high gloss makes daytime use significantly less troublesome. In terms of pure brightness output in the SDR standard, that is for television, the TV achieves an average brightness of around 420 nits. This isn't an outstanding result that would allow it to combat direct sunlight hitting the screen, but it's perfectly sufficient for comfortable viewing of content in a moderately sunlit living room.

The LG G6 will perform exceptionally well as a television in a brightly lit room. Thanks to its powerful peak brightness, the television can easily cut through most external light sources. Best of all, the new generation of the Tandem OLED panel has brought significant improvements in the reduction of reflections. Although the screen coating is still glossy (and thus maintains well-saturated colours even in challenging conditions), it effectively suppresses glare. It does this definitely better than classic OLED screens with a standard glossy coating. We could confidently compare this level to that of glossy QD-OLED panels, but with one key advantage in favour of LG. Unlike the technology of competitors, in this model, deep blacks remain intact in a bright living room. There is no risk of greyness or a purple hue due to incoming light – the blacks in the G6 during the day are simply perfect, just as they are at night.

Smart Features

Similar to the products under the TCL brand, the iFFALCON U85X benefits from the Google TV system. This means access to an almost limitless library of applications, from the most popular VOD services to niche tools, as well as full integration with Google's voice assistants and Gemini. Users of the Apple ecosystem have also not been overlooked – the television works seamlessly with their devices thanks to the built-in AirPlay feature. The system itself runs quite smoothly, although it cannot be denied that it inherits some shortcomings known from TCL models. The interface can sometimes "hitch", requiring a moment's thought, and the Polish translations in the deeper corners of the menu can be quite odd and at times illogical.

Classic Features

In the area of traditional television functions, the iFFALCON U85X does not strive for any extravagance and offers the absolute minimum, which may be somewhat disappointing for more demanding users of traditional cable or satellite services. One will futilely search for the ability to record programmes to external USB memory or a picture-in-picture (PiP) mode that would allow tracking two sources simultaneously. From the more "modern" classics, we only get the option to wirelessly connect headphones via Bluetooth and teletext support. The remote control also does not pretend to be a modern gadget from the future; it is a classic design with a full numeric keypad, which makes it easy to quickly jump between channels, but visually it significantly lags behind minimalist trends.

webOS System and Smart Features

The television operates on the latest version of the webOS system. While it is a closed platform, it supports absolutely all the key streaming applications on the market. You can easily launch useful wireless connectivity features here, such as built-in Chromecast, AirPlay, or classic screen mirroring. However, the biggest distinguishing feature of the LG platform remains the brilliant Magic remote. Though it is quite compact and lacks a physical numeric keypad, it does something that competitors still cannot replicate – it works like a wireless mouse. It is equipped with a gyroscope, allowing us to intuitively move the cursor across the screen, which drastically speeds up typing passwords or navigating menus. Additionally, LG has one of the best voice assistants for device control, and this combination with the Magic remote provides excellent navigation capabilities within the system. The only thing that can be quite irritating here is the intrusive advertisements and sponsored tiles that LG increasingly clutters the main screen of the system with. Nevertheless, the absence of Google TV is no drawback for the G6 – considering the smooth operation of webOS, one can confidently say that it is even an advantage.

Features for Traditionalists

In terms of traditional television, the LG G6 also performs excellently and does not forget traditional users. Despite the minimalist remote, it is packed with numerous useful solutions. The manufacturer has not given up on PVR functionality, allowing recording of programmes from built-in tuners directly onto external USB storage or a hard drive. We also have a smoothly functioning TimeShift for pausing live television and the option to schedule recordings. These features could prove invaluable during the upcoming World Cup in football when matches will be played late in the evening, and we may not be able to watch them live. Of course, it also includes standard functions, such as the ability to connect wireless headphones via Bluetooth.

Playing files from a pendrive is no challenge for the iFFALCON U85X - the built-in player handles almost every audio and video format we thrown at it during testing without a hitch. The only drawback we could point out is the support for external subtitles; while popular formats like .sub and .srt work flawlessly, the television can be temperamental with .txt files. Fortunately, with the presence of the Google TV system, this problem can be quickly resolved by installing an external app like VLC. However, for most users, the factory tool will likely be more than sufficient to enjoy their own media library without any unnecessary hassle.

The lack of the ability to install an external media player (as is the case in Android-based systems) is actually no problem for the LG G6. The built-in factory player works great and effortlessly handles most audio, video or photo formats that we provided it from our USB flash drive. However, during testing, we encountered some deficiencies – notably a rather strange lack of support for subtitles in the popular .txt format. However, we believe that this option will quickly make its way to the G6 with the next software update.

iFFALCON U85X proves that the absence of the Onkyo or Bang & Olufsen logo on the casing does not necessarily mean flat and tinny sound. The audio system in this model plays surprisingly well, largely thanks to the dedicated subwoofer located at the back of the device. Our acoustic measurements confirm that the low end starts to "come alive." It is this distinct "hump" on the graph that is responsible for the noticeable dose of bass, which adds the weight and depth often missing in televisions to films and music. The only point of contention may be the fact that such bass can muffle the high tones, which may seem somewhat recessed. Overall, it can produce sound levels up to 83 dBC, which is more than sufficient for amplifying a larger lounge.

Despite its very flat casing, the LG G6 sounds surprisingly good. The manufacturer has managed to squeeze some quite nice speakers under the panel, which can produce a sound that is fairly "spatial" – if one can even call the limited physical capabilities of the television such a thing 😉. The sound is clear, has decent dynamics, and will perform flawlessly for everyday viewing of news programmes or series. The television also easily supports the very popular spatial audio codec Dolby Atmos.

Unfortunately, for the second year in a row, there is no support for the DTS:X format. Regardless of what one might say, it has recently become quite unpopular in streaming services, but a television in the top price and quality tier simply should not restrict users in terms of audio format support. Additionally, we must complain that LG has somewhat castrated the audio menu itself. We missed more advanced settings and predefined sound profiles, of which there were definitely more in last year's model.
