Our verdict

The iFFALCON U85X is a device that draws heavily from the technological solutions of its parent brand, TCL. It is hard not to get the impression that in terms of pure technical parameters, we are dealing with nearly a faithful copy of the successful C6K series (C69K/Q6C), although visually, 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 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, just like the models from the C series, the iFFALCON U85X turns out to be exceptionally tailored to the needs of gamers. You will find almost every function necessary for comfortable gaming, from full support for HDMI 2.1 ports, through ALLM and VRR technologies for console owners, to excellent compatibility with PCs. As a monitor, the device performs superbly not only due to its refresh rate support up to 240Hz but also because of its very sharp and legible font, which is not always a given in the world of televisions. Of course, it is not an ideal model, as it shares the same set of advantages and disadvantages as its counterpart under the TCL brand – mainly referring to issues like noticeable motion blur and aggressive brightness management in HDR. However, it all creates an extremely interesting mix that makes us seriously contemplate the sense of the existence of the iFFALCON brand as a separate entity, since the same product could successfully debut with a full-fledged TCL logo on the casing. Nevertheless, we have no major reservations about the device itself; it is truly a model worth attention as long as you manage to purchase it, as it is very difficult to obtain at the moment.

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 on the most important points it still delivers exactly what many people choose the technology for: perfect black, very high contrast, and a picture that can simply look spectacular in movies. This is largely thanks to the new budget WOLED panel, called 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 level you can actually notice while watching. Bright elements have more punch, the picture handles more demanding scenes better, and combined with OLED blacks the whole thing can look really impressive. Movies and series from streaming platforms fare especially well, particularly those available in Dolby Vision. That's when the B6 makes the most of its capabilities and can produce a picture that will be a big step up for someone moving from a typical LCD TV. However, it's not a model without compromises. Our biggest reservation is how the screen handles reflections. The lack of a classic polarizer 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 itself loses some of its character in a bright room. In controlled viewing conditions this won't be an issue, but for a very bright living room you should approach this purchase with some caution. The operation of webOS also leaves something to be desired. It is still very good overall, with a rich app library, a convenient Magic Remote, and pretty much 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 tell the new version of the system is more demanding and a bit "heavier" than before. Despite these notes, 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 turns up on a good sale, because that's when it can be one of the most interesting choices for people who want to get into 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.

In terms of black levels and contrast, the 65-inch iFFALCON U85X is almost an exact replica of the solutions known from TCL's 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 can generate an image with impressive depth, where our measurements in real movie scenes indicated a contrast exceeding 100,000:1. Of course, at this level of hardware, local dimming does not always exhibit perfect precision, so in more challenging scenes with bright details on a dark background, we have to reckon with the occurrence of halo effects, which are subtle glows around objects. Nevertheless, the overall quality of black levels is very high and will certainly satisfy the majority of users seeking cinematic experiences. The image certainly appears to have greater depth than in solutions without any local dimming technology.

Black levels on the LG OLED B6 are perfect. That's no surprise, since it's an OLED (WOLED), but this is where you can really see why this technology still has so many fans. Each pixel can turn off individually, so in dark scenes there's no gray haze or light bleed around bright elements. That gives the image excellent depth and can make it look truly three-dimensional. Shadow detail also holds up well. Nothing blends into one dark blotch, and fine details remain visible even in more challenging scenes. In that respect, the B6 simply showcases everything we love about OLED TVs.

LG OLED B6

IFFALCON U85X

Luminance of RGB colors

iFFALCON U85 handles HDR in a rather dual manner – on one hand, it can surprise with a solid peak brightness of around 650 nits, which places it well above average in this price segment. This is particularly evident in full-screen, bright scenes. Examples from movies like Life of Pi or the final test sequences from The Meg prove that the TV can maintain the strength and essence of the HDR effect when the entire panel has to "light up," delivering truly satisfying experiences. However, problems begin in high-contrast scenes, where smaller, bright details appear on the screen; the dimming algorithms prioritize deep blacks to such an extent that they can suppress the brightness of small highlights to just 100 nits, drastically reducing the dynamism of the image and depriving us of the true "punch" we expect from HDR standards. However, the question of colors remains a sweetener; thanks to the use of the PFS phosphor filter (marketed as QLED by the manufacturer), they look very good, achieving nearly 94% coverage of the DCI-P3 color palette, allowing for a rich and vibrant image in most content.

The LG B6 is a moderately bright OLED. After calibration it reaches about 800 nits, roughly 200 nits more than last year’s B5. That’s thanks to the new budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR in many scenes look fuller than on last year’s lower-tier OLEDs. That doesn’t mean the B6 has no limits. In very bright shots, when a large part of the screen is strongly lit, brightness can drop below 400 nits. This behavior is typical for OLED TVs (especially those from this segment) and that’s when you see the biggest difference versus more expensive models. All things considered, we rate the B6’s results as really solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that you can really feel the step up from ordinary SDR in films.

Color gamut

Using the OLED SE panel has slightly affected wide color gamut coverage. Compared with last year’s model, results fell by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn’t mean the colors on the LG B6 are weak. In most movies and series they look lively, well saturated and simply pleasing to the eye. You only notice a difference in very bright, highly colorful scenes. Then colors lose some intensity compared with QD-OLED panels. This comes from the WOLED panel construction. Besides red, green and blue subpixels it also uses a white subpixel that helps boost brightness. It comes at a cost: at very high luminance some color is effectively “diluted” by the white light, so saturation of some colors can be slightly lower. In everyday use this isn’t a big issue, but you can notice it in the most demanding scenes.

Factory Mode

After calibration

We tested the factory colors in 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 problem that stands out in both SDR and HDR content is improper white balance - an excess of blue and red components gives the image a slight purple tint, which undermines the naturalness of film scenes. However, an even greater challenge is the way the television manages its brightness. Analyzing the gamma curve for the SDR signal, we noticed significant instability: instead of sticking to the reference value of 2.4, the device oscillates around 2.2, only to suddenly experience an unnatural jump to around 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 feature can be found in the EOTF curve, which makes the image unpredictable and loses its cinematic authenticity.

We tested the LG B6 in Filmmaker Mode, which is the best picture setting available right out of the box. ISF modes deliver very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of those modes is, after all, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. With SDR content, the factory settings perform really well. Color errors are small, gamma behaves properly, and the image looks natural during ordinary viewing and does not seem overly "pumped up." It's a bit worse with HDR. When you play that kind of content you can quickly see that the white balance hasn't been set perfectly. Too much blue and red causes the image to shift toward a slightly pink tint. This is also confirmed by measurements of the color gamut and the ColorChecker, where samples clearly drift in that direction. It's not a flaw that completely ruins the picture, but you can notice it in HDR films. So people who care about the most faithful image should consider the calibration we describe later in the review.

After professional calibration of the movie mode, we must admit that the effect is more than satisfactory – the iFFALCON U85X undergoes a true transformation. Color errors in SDR content dropped to a level below 2, making them practically imperceptible to the human eye. We managed to set the white balance almost perfectly, and brightness management (gamma) became nearly exemplary. As a result, with standard quality materials, the television looks simply perfect, and it's hard to find any faults with it.

In the case of HDR signal, the situation has also improved significantly, although here the nature of the device is a bit more pronounced. Color 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 chart (available on the right side of the screen in the filters: 4K HDR, gamma / EOTF) to see what is not immediately visible regarding brightness management by the U85. Although the reference line looks decent, in actual 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 ailment of almost every Mini-LED that has to reconcile high brightness with an attempt to maintain deep black. One just has to be aware of these technical limitations, which are unavoidable in this segment.

During calibration we focused primarily on HDR content, because that's where the factory settings required the biggest corrections. We didn't neglect SDR mode, though, which after adjustment was brought almost to perfection. Colors are very accurate and brightness is handled as it should be. The biggest improvement in HDR came from correcting the white balance. After removing the excess red and blue, the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colors that had been shifting toward magenta 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. The LG B6 can therefore deliver a very accurate image, especially for the manufacturer's entry-level OLED model.

Smoothness of tonal transitions

These are selected scenes that show smooth tonal transitions from one color to another. If you see distinct banding, it’s the TV panel’s fault.

When it comes to the smoothness of tonal transitions, the iFFALCON U85X performs quite decently. In most scenes, gradients are almost imperceptible, so the irritating "banding" of colors shouldn't be noticeable during everyday viewing, for example, on ChooseTV. However, it must be honestly admitted that in very dark frames, the image is not always perfectly smooth, and certain imperfections in transitions between shades can be observed. Nonetheless, this result is more than satisfactory and does not spoil the overall perception of the image.

Tonal transitions on the LG B6 are quite good, though you can still see some limitations typical of WOLED panels. In most scenes, colors transition smoothly between shades, without noticeable banding or unwanted digital artifacts. It's not always perfect, however. Most problems appear in the dark areas of the image, where WOLED panels have long been somewhat weaker. This is partly due to the greater difficulty of driving the panel at very low brightness and to the design's use of a white subpixel. Compared with last year's model there is a slight improvement, but it still doesn't reach 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.

When it comes to scaling the image to 4K resolution, the iFFALCON U85X performs solidly. The device efficiently enhances low-quality signals, making even older materials look clean and clear on the 4K matrix. At extremely low resolutions, such as 480p, you can notice slightly jagged edges (especially on thin lines), but let's face it – this is a scenario you'll only encounter when watching very old footage, so it's not a real issue in everyday use.

However, the digital processing aimed at smoothing tonal transitions is significantly worse. Although the menu features a function called “Gradual Smoothing”, its effectiveness is at least debatable. In practice, it does not effectively reduce banding (color stepping), and worse, it can cause more harm than good. This filter can be too aggressive where it shouldn't be, artificially smoothing out details that should not be touched, such as the natural texture of the face or fine details of the skin's texture. Instead of improving quality, this feature can give the image an unnatural, “plastic” look, so it's best to use it with great caution or, better yet: leave it turned off.

The LG B6 handles lower-quality sources very well. Much of the credit goes to effective digital image processing, which can mask some source imperfections without overly smoothing the whole scene. The feature "Smooth Gradation" proves particularly useful. It can significantly reduce posterization, which we mentioned earlier, especially in darker areas of the image. The safest choice remains Low or Medium. The function still effectively smooths harsh tonal transitions, but does not yet interfere too much with fine details. The most dedicated purists can, of course, leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a good amount of detail, and the image is neither overly sharpened nor excessively blurred. Some limitations become noticeable only with very poor sources below 720p, where the smallest subtitles and fine elements are not always perfectly sharp, but this is true for almost every other TV on the market.

In contrast to budget constructions, which in dynamic sports scenes may resemble a slideshow, the iFFALCON U85X is a heavyweight contender equipped with a panel featuring a native refresh rate of 144Hz. However, it is worth remembering that in the world of movies, series, or sports, we will mostly operate at 120Hz due to the specifics of image enhancement systems. Such a fast panel is excellent news for gamers and sports fans, as it opens the door to advanced motion settings that simply don't exist in cheaper 60-Hz models.

We manage everything from the "Motion Clarity" menu, where instead of using pre-set, often too aggressive modes, we definitely recommend a custom configuration based on two sliders. The most important of them, reduction of flicker, is responsible for smoothness in films – here, it's best to aim for a value around 4, which will maintain a natural, cinematic character of motion without falling into the artificial "soap opera effect." On the other hand, the first slider, reduction of blur, 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, and annoying trailing is eliminated.

One of the biggest advantages of OLED panels is their very fast pixel response time. This keeps the image sharp and prevents the visible smearing that often appears on LCD TVs. However, there is a downside. During slow camera pans, motion can look more choppy than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 you can easily soften this with TruMotion. With the motion smoothing properly adjusted, you can achieve smoother motion without giving the picture an excessive soap-opera effect.

iFFALCON U85X is an exceptional device for gamers that has virtually everything you can expect from a modern screen for consoles or PCs. Here we find two fully-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 and with minimal latency. The TV handles high refresh rates at various resolutions without any problem, and a real curiosity is the mode that allows for up to 240Hz when dropping to Full HD quality. The entire system is managed by the Game Bar (a faithful copy from TCL), which allows for instant switching of picture modes, customization of the interface appearance, or even adding a virtual crosshair in the middle of the screen.

LG OLED B6 offers a powerful set of advantages for gamers; it's simply a complete platform for PS5, Xbox Series X/S, or a solid PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can skip the annoying cable swapping when you want to connect several newer devices at once. We get the full suite of sync technologies – from classic VRR to G-Sync and FreeSync. The screen seamlessly matches the refresh rate to the frame output produced by the console or graphics card. Of course ALLM is included: the B6 automatically detects a running game and immediately cuts input lag to a minimum. HDR handling is also excellent. The TV supports Dolby Vision, and a properly implemented HGiG standard means that after an initial calibration in the console settings the picture won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on top is the Game Bar. Instead of digging through the full menu during gameplay, one click lets you adjust shadow visibility, tweak selected settings, or simply check the display’s current operating mode. All of this makes the LG B6 a great choice for gamers.

The completion of the gaming arsenal is the remarkable latency results that we measured in our tests. With a standard 60Hz signal, the input lag is only 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 still comes with additional processor overhead and increased lag, but here the engineers at TCL (or iFFALCON) did a great job.

Input lag in 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, where input lag can increase to around 25 ms. That's still not a bad result, but the most demanding players using an Xbox may already feel a difference compared to standard HDR.

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 a great candidate for a powerful computer monitor, offering a work culture that is hard to find in typical televisions. The readability of the fonts is at almost an exemplary level – although due to the specifics of the VA panel, it is not as crystal clear as in IPS panels, the difference becomes practically undetectable to the human eye when maintaining a distance of over one meter. 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 giant an excellent tool for fast-paced esports titles, where refresh rate takes priority over pixel count. What is almost most important for PC users, such high performance is fully supported by frame synchronization technologies such as NVIDIA G-Sync and AMD FreeSync, which effectively eliminates screen tearing and ensures perfect smoothness regardless of the graphic card in use.

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 fault it for gaming. Compared with pricier 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. What may matter more is the WOLED panel's subpixel structure. Because it uses four subpixels, small fonts in Windows aren't perfectly sharp and you can sometimes see slight colored fringes around them. For occasional web browsing or computer work that probably won't be an issue. However, anyone planning to buy a smaller variant, for example 48 inches, and use it as their main monitor at a desk should keep that in mind.

In terms of viewing angles, the iFFALCON U85X does not offer any surprises – it is simply poor, which is a typical characteristic of VA matrix screens. We must treat this as a natural and conscious compromise: when choosing a panel with high contrast and deep blacks, we almost always sacrifice wide viewing angles (only in top-end series do manufacturers use special coatings to improve this feature). The laws of physics in this price segment cannot be deceived, because while sitting directly in front of the television, the picture looks stunning, it only takes a slight lean to the side for the colors to start losing their saturation. If you plan on evening screenings with a larger group, it's a good idea to ensure that everyone sits as close to the central axis of the screen as possible.

Viewing angles on the LG B6 are very good, which is typical for almost all OLED TVs. Even at extreme side angles the picture maintains strong color saturation and doesn't noticeably lose brightness. In this respect, really only models with QD-OLED panels perform better. However, there's one thing worth mentioning. Some WOLED panels may show a slight greenish tint at extreme angles. This isn't a rule; some units exhibit the effect more, others hardly at all. It depends on the specific unit.

LG OLED B6: 313 cd/m2

IFFALCON U85X: 419 cd/m2

In a bright room, the iFFALCON U85X performs reasonably well, thanks to the satin coating used on the panel. It adequately dampens direct light reflections, allowing us to avoid the irritating mirror effect, although under stronger lighting, one can notice the characteristic warm "spills" of light around the reflecting objects. While it is not on par with top-tier panels featuring the most advanced filters, the absence of high gloss makes daytime use much less burdensome. In terms of pure brightness in SDR standard, that is for television, the TV achieves an average brightness level of around 420 nits. This is not an outstanding result that would allow it to compete with direct sunlight hitting the screen, but it is perfectly sufficient for comfortable viewing in a moderately sunny living room.

In the case of 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 it handles direct light reflections worse. The reason is a less effective polarizer, so reflections from windows or lamps are less effectively 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 subtly diffuse reflections, but it doesn't eliminate them as effectively as earlier solutions. And in this 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 on the panel.

That doesn't mean, of course, that the B6 is unsuitable for a bright living room. The higher screen brightness helps cut through ambient light, and during normal viewing the picture remains readable. The problem starts when there's a large window or a strong lamp opposite the TV. In those conditions the B6 doesn't perform at its best. So it's best used in a room where you can at least partially control the light falling directly on the screen.

Smart Features

Like products from TCL, the iFFALCON U85X benefits from the Google TV system. This means access to an almost unlimited library of applications, from the most popular VOD services to niche tools, as well as full integration with Google and Gemini voice assistants. Apple ecosystem users are also not left out – the television easily works with their devices thanks to the built-in AirPlay feature. The system itself operates quite smoothly, although it's undeniable that it inherits some issues known from TCL models. The interface can sometimes "catch its breath" and needs a moment to think, and Polish translations in the deeper corners of the menu can be quite strange and occasionally illogical.

Classic Features

In terms 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. It’s futile to look for features like recording programs to external USB memory or picture-in-picture (PiP) mode, which would allow following two sources simultaneously. From the more "modern" classics, we only get the ability 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’s a classic design with a full numeric keypad that makes it easier to jump quickly between channels, but visually it strongly diverges from minimalist trends.

Smart TV: webOS

LG B6 runs webOS, LG’s proprietary platform. Its biggest strength remains the way it’s controlled. The included Magic Remote works like a mouse; just move your wrist to move the cursor across the screen and point at the items you want. It may feel unusual at first, but it quickly proves very convenient, especially when typing text, selecting apps, or navigating a complex menu. The remote itself is fairly 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 type 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’s hard to fault webOS. You’ll find practically all the major streaming services here, as well as extra features like AirPlay, screen mirroring, and Chromecast. The TV therefore works well with both Apple phones and Android devices. It’s just a pity that the system on the B6 doesn’t run as smoothly as on higher-end models. At times it can respond with a slight delay, and the home screen is heavily loaded with recommendations, tiles, and ads. That doesn’t make webOS unusable, but it could certainly be more organized.

Classic features

By contrast, the traditional TV features perform very well—features many manufacturers are starting to forget. The LG B6 lets you record programs to an attached hard drive or USB storage. The PVR function also supports scheduling, so you can program recordings in advance from the TV guide. This comes in 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 solid support for 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 doesn’t bother you.

Playing files from a USB drive is no challenge for the iFFALCON U85X – the built-in player handles almost every audio and video format we threw 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 TV can be finicky with .txt files. Fortunately, with the presence of Google TV, this problem can be quickly resolved by installing an external VLC-type application. Still, for most users, the factory tool will probably be more than sufficient to enjoy their own multimedia library without unnecessary hassle.

The LG B6’s built-in player handles most popular video files played from USB without any major problems. The TV also properly supports subtitles and the most common audio formats, though it lacks DTS support. The situation is somewhat worse for photos. The list of supported formats is fairly limited and does not include 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.

iFFALCON U85X proves that the absence of the Onkyo or Bang & Olufsen logo on the casing does not have to mean flat and shrill sound. The audio system in this model performs surprisingly well, largely due to the dedicated subwoofer located at the back of the device. Our acoustic measurements confirm that the lower frequencies begin to "respond." It is this discernible "bump" on the graph that accounts for the noticeable dose of bass, which typically provides weight and depth to films and music that are often lacking in televisions. The only criticism one might have is that such bass can overpower the high tones, making them seem a bit muted. Overall, it can deliver sound at a level of up to 83 dBC, which is more than sufficient for amplifying a larger living room.

In terms of sound, the LG B6 performs very similarly to last year's model. It still uses a 2.0 speaker setup rated at 20 W, which is more than enough for everyday viewing. Dialogue is clear and the sound doesn't sound bad, but there's no sense of space, 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 problem, however, is not the speakers themselves but the settings. Compared with its predecessor, a large portion of the options for tailoring the sound to your preferences has disappeared. A few preset modes remain, including AI and Standard, but the ability to fine-tune the audio is much more limited than it was a year ago.
