Our verdict

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.

The 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 in the most important areas it still manages to deliver exactly what many people choose this technology for: perfect blacks, very high contrast and a picture that can simply look spectacular in films. Much of this is thanks to the new budget WOLED panel, the OLED SE. Thanks to it, LG's cheapest OLED is now noticeably brighter than a few years ago, and around 800 nits in HDR is a figure you can genuinely notice when watching. Highlights have more punch, the picture copes better with more demanding scenes, and combined with OLED blacks the whole thing can look really impressive. Films and series from streaming platforms look particularly good, especially those available in Dolby Vision. That's when the B6 makes the most of its capabilities and can deliver an image that will be a big step up for someone switching from a typical LCD TV.

However, this is not a model without compromises. Our biggest reservation concerns 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 blacks themselves lose some of their character in a bright room. In controlled conditions this won't be a problem, but for a very bright living room it's worth approaching this purchase a little more cautiously. The operation of webOS also leaves something to be desired. The system itself is still very good, with a rich app library, the convenient Magic Remote and essentially everything you would expect from a modern Smart TV. The problem is that on the B6 it does not always run as smoothly as it should. At times you can feel the new version of the system is more demanding and somewhat 'heavier' than before.

Despite these remarks the LG B6 still performs very well. It's a TV that delivers all the key advantages of OLED while not costing as much as the higher-end models. It makes the most sense when it's on a good deal, because then it can be one of the most interesting choices for people who want to enter the world of OLEDs 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.

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".

The blacks on the LG OLED B6 are perfect. That's no surprise, since we're dealing with an OLED (WOLED), but this is precisely where you can see why this technology still has so many fans. Each pixel can switch off individually, so in dark scenes there is no grey halo or blooming around bright elements. As a result, the image has excellent depth and can genuinely look three-dimensional. Shadow detail also performs well. Nothing melts into one dark blotch, and small elements remain visible even in more challenging scenes. In that respect the B6 simply demonstrates everything we love about OLED TVs.

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.

The 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 the new, budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR look fuller in many scenes than on last year’s lower‑end OLEDs. That does not mean the B6 has no limitations. In very bright shots, when a large part of the screen is strongly lit, brightness can fall below 400 nits. This behaviour is typical for OLED TVs, especially in this segment, and that’s where you see the biggest difference compared with more expensive models. Even so, we judge the B6’s results as genuinely solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that films truly feel like a step up from ordinary SDR. Colour gamut Using the OLED SE panel has had a slight impact on wide colour gamut coverage. Compared with last year’s model the results have fallen by a few percentage points. It covers roughly 96% of DCI‑P3 and about 71% of BT.2020. That doesn’t mean the colours on the LG B6 are weak. In most films and series they look lively, 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 stems from the WOLED panel structure. Besides red, green and blue subpixels it also uses a white subpixel, which helps to boost brightness. However, this comes at a price. At very high luminance some colour is effectively 'diluted' by the white light, so the saturation of certain colours can be slightly lower. In everyday use this isn’t a major issue, but in the most demanding scenes you can notice it.

Factory Mode

After calibration

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.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes produce very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is, in any case, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. On SDR material the factory settings perform really well. Colour errors are small, the gamma response is correct, and the picture during normal viewing looks natural and does not feel overly "pumped up". It's a bit worse with HDR. When such content is played you quickly see that the white balance hasn't been set perfectly. Too much blue and red gives the image a slightly pink tint. This is also confirmed by colour gamut measurements and the ColorChecker, where samples clearly shift in that direction. It's not a flaw that completely spoils the picture, but it is noticeable with HDR films. Therefore anyone who wants the most faithful image should consider calibration, which we cover further on in the review.

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.

During calibration, we concentrated mainly on HDR content, because that's where the factory settings needed the most correction. We did not, however, neglect SDR mode, which after adjustment was brought almost to perfection. Colours are very accurate, and brightness is controlled as it should be. The biggest improvement in HDR came from fixing the white balance. Removing the excess red and blue eliminated the pinkish tint, and the image became much more natural. Skin tones, whites and all colours that had previously shifted towards pink improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. So the LG B6 can deliver a very accurate picture, particularly for the manufacturer's entry-level OLED model.

Smoothness of tonal transitions

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.

Tonal transitions on the LG B6 are quite good, although some limitations typical of WOLED panels are still evident. In most scenes colours move between shades smoothly, without noticeable banding or unwanted digital artefacts. However, it is not always perfect. Most issues appear in the dark parts of the image, where WOLED panels have struggled for years. This is partly due to the greater difficulty of controlling the panel at very low brightness and the specific design that uses a white subpixel. Compared with last year’s model there is a slight improvement, but it still does not match the level of the best QD-OLED TVs or more advanced LCD models.

Image scaling SD (576i)

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

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.

The LG B6 handles lower-quality material very well. This is largely thanks to effective digital image processing, which can mask some of the source’s imperfections without overly smoothing the whole scene. The "Smooth Gradation" function proves particularly useful. It noticeably reduces posterisation, especially in dark parts of the image. The safest choice remains the Low or Medium setting. The function still effectively smooths out unsightly tonal banding, but does not yet interfere too much with fine details. Purists can of course leave it switched off. Upscaling to 4K also performs very well. Full HD and 720p material retain a good amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations only become apparent with very poor sources below 720p, where the smallest text and fine elements are not always perfectly sharp, but this applies to almost every other TV on the market.

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.

One of the biggest advantages of OLED panels is the very fast pixel response time. This keeps the picture sharp and free of the visible smearing often seen on LCD TVs. However, there is a downside. During slow camera pans motion can look choppier than on LCD screens, where some of that effect is naturally masked by the slower panel. Fortunately, on the LG B6 this can be easily mitigated using the TruMotion system. With the motion smoothing set correctly you can achieve smoother motion without giving the picture an exaggerated soap opera effect.

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.

LG OLED B6 has plenty to offer gamers; it’s simply a complete base for PS5, Xbox Series X/S or a capable PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can avoid irritating cable swapping when connecting several newer devices at once. It offers a full suite of synchronization technologies, from standard VRR to G-Sync and FreeSync. The screen synchronises the refresh rate seamlessly with the frame output from the console or graphics card. Of course it includes ALLM: the B6 automatically recognises when a game is running and immediately reduces latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG standard means that, after initial calibration in the console settings, the image won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on the cake is the Game Bar. Instead of digging through the full menu during gameplay, a single click is enough to adjust shadow visibility, tweak selected parameters or simply check the current display mode. All of this makes the LG B6 an excellent choice for gamers.

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.

Input lag in the LG B6 is very low. At 120 Hz it is 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 slightly worse, with input lag rising to around 25 ms. That's still not a bad result, but the most demanding Xbox gamers may already notice a difference compared with standard HDR.

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.

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

The subpixel structure of the WOLED panel may be more significant. Because it uses four subpixels, small fonts in Windows are not perfectly sharp and you can sometimes see subtle coloured fringes around them. For occasional web browsing or general computer work this is unlikely to be a problem. However, anyone planning to buy a smaller variant, for example a 48-inch model, and use it as their primary monitor at their desk should bear that in mind.

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.

Viewing angles on the LG B6 are very good, which is typical for almost all OLED TVs. Even when viewed from a wide angle the image retains high colour saturation and does not noticeably lose brightness. In this respect, only models with QD-OLED panels really perform better. However, there is one thing worth mentioning. Some WOLED panels may show a slight greenish tint at very wide angles. This is not a rule. Some units exhibit this effect more, others hardly at all. It depends on the individual unit.

LG OLED B6: 313 cd/m2

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

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.

In the case of the LG B6, one of the biggest changes comes from the new OLED SE panel. The TV is slightly brighter than its predecessor, but at the same time it is worse at dealing with direct reflections. The reason is a less effective polariser, so reflections from windows or lamps are less well suppressed and blacks in a bright room can look slightly lifted. LG tried to partially mask this effect with a satin screen coating. It does help to gently diffuse reflections, but it does not eliminate them as effectively as the solutions used previously. And in this respect the B series falls furthest behind the previous generation. By day the screen no longer looks as clean, and strong light sources can be clearly reflected on the panel. That does not, of course, mean the B6 is unsuitable for a bright living room. The higher screen brightness helps to cut through ambient light and during normal viewing the picture remains readable. The problem starts when there is a large window or a bright lamp opposite the TV. In those conditions the B6 does not perform at its best. It is therefore best suited to a room where you can at least partially control the light falling directly on the screen.

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.

Smart TV: webOS

LG B6 uses webOS, LG’s proprietary platform. Its biggest advantage remains the way you control it. The supplied Magic Remote works much like a mouse; simply move your wrist to shift the cursor across the screen and point at the items you want. At first it may feel unusual, but it quickly proves very convenient, especially when typing text, selecting apps or navigating a complex menu. The remote itself is fairly minimalist and does not offer many traditional buttons, but cursor control largely makes up for that. On the other hand, if you do not want to wave your hand to enter letters, you can always speak the desired phrase into the remote and the AI voice assistant will suggest appropriate recommendations.

In terms of available apps it is hard to fault webOS. You will find virtually all the major streaming services here, as well as additional features such as AirPlay, screen mirroring and Chromecast. The TV therefore works well with both iPhones and Android devices. It is a shame, however, that the system does not run on the B6 as smoothly as on higher-end models. At times it can respond with a slight delay, and the home screen is heavily cluttered with recommendations, tiles and ads. That does not make webOS unusable, but it could certainly be more organised.

Classic features

By contrast, the traditional TV features perform very well, features many manufacturers seem to be gradually forgetting. The LG B6 allows, among other things, recording programmes to a connected drive or USB storage. The PVR function also works with a scheduler, so a recording can be planned in advance from the TV guide. This comes in handy when you want to save an episode, a match or another event broadcast during your absence. There is also a clear channel guide and efficient handling of terrestrial, cable and satellite TV. For people who still regularly use traditional television, the B6 is therefore a relatively complete device, provided the lack of teletext does not bother you.

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.

The LG B6's built-in player handles most common video files played from USB without much trouble. The TV also correctly supports subtitles and the most common audio formats, although it lacks DTS support. The situation is slightly worse for photos. The list of supported formats is rather limited and does not include, among others, HEIC, the format in which photos taken with an iPhone are saved by default. Such files therefore need to be converted to JPG beforehand, or you can simply use the AirPlay function.

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.

In terms of sound, the LG B6 performs very similarly to last year's model. It still uses a 2.0 speaker setup delivering 20 W, which is perfectly adequate for everyday viewing. Dialogue is clear and the sound isn't bad, but there is no soundstage, dynamics or bass you'd expect from higher-end models. The TV supports the Dolby Atmos spatial audio format, but lacks DTS:X. The main problem, however, isn't the speakers themselves but the settings. Compared with its predecessor, many of the options for tailoring the sound to your own preferences have disappeared. A few presets remain, including AI and Standard, but the ability to fine-tune the sound is much reduced compared with a year ago.
