LG OLED G6 is undoubtedly one of the most anticipated releases of this year. The immense interest stems primarily from the use of the new generation Tandem OLED (2nd generation) panels, which are designed to eliminate flaws and introduce improvements compared to last year's G5 model. The manufacturer also adds an updated image processor, namely Alpha 11 gen. 3, along with a package of new SmartTV features. All of this has significantly heightened consumer expectations. In this review, we assess how these announcements translate into real-world results and whether the G6 can truly become the television of the year.
The store sample for testing was loaned to us by one of our viewers/readers, for which we are very grateful. 🙂
LG G6 - Our verdict
8.7
Overall rating
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 front of the new G6 will not surprise anyone who follows flagship models from LG – the Koreans simply deemed the G series to be a tried and tested design. However, it must be said that this is a piece of solidly crafted top-tier equipment. The whole thing is enclosed in a uniformly flat casing, held together by a raw, metallic frame in a graphite-silver hue. It looks very good, minimalist, and as a result, we focus our gaze on the screen itself.
When buying this model, it is important to pay attention to the labels, as LG traditionally divides the Gallery series into two versions. A box with the notation "LW" arrived at our editorial office. This means that inside, instead of classic legs, we get a dedicated mount. Since we didn't fancy drilling holes in the wall in the laboratory 😉, we had to resort to a universal VESA stand. If you plan to place the television on a dresser, be sure to look for the "LS" version with a central base. However, remember that it is the "LW" variant we tested that extracts one hundred percent from this design. Once hung, the television literally aligns with the wall and becomes a modern piece of art.

Visibility of details in the lights:
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 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.
Scene from the movie “Pan” (about 2800 nits)
Scene from the movie “Billy Lynn” (about 1100 nits)
Thanks to such high peak brightness, the LG G6 is capable of reproducing HDR content with truly cinematic precision. The image here is uncompromising: what is meant to be bright is extremely bright, and what is meant to be dark remains perfectly black. The television performs excellently whether we are watching classic HDR productions mastered to 1000 nits or those exceptionally challenging for the equipment, reaching up to 3000 nits – such as the bright scenes from the film Pan. Even in such demanding conditions, details in the brightest areas, e.g., the sun, are superbly reproduced, and the image does not suffer from loss of detail.
HDR luminance chart:
Although the LG G6 is an extremely bright television, it still gains a lot when playing content encoded in Dolby Vision with dynamic metadata. In the manufacturer's brochures, there is much to read about the new processor and its advanced dynamic tone mapping feature for standard HDR10. Our tests showed that this feature, besides a slight improvement in detail visibility, unfortunately artificially boosts the brightness of the entire screen – which is why we recommend turning it off. Fortunately, this is not a serious issue, as the television has full support for Dolby Vision. What the processor tried to force with an artificial algorithm happens naturally here thanks to dynamic metadata. This is clearly visible in our comparison of images – in challenging scenes, such as horses on a white, vivid meadow, the Dolby Vision format allows for the recovery and display of even more hidden details in the white areas that standard HDR10 could not properly separate.
Static HDR10
Dynamic: Dolby Vision
Factory color reproduction
7.4/10
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.
Color reproduction after calibration
9.2/10
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.
LG G6 - Smoothness of tonal transitions
5.5/10
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 and smoothness of tonal transitions
8.7/10
Smooth transition function
Image without overscan on the SD signal
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.

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.

Blur (4K@165Hz):
Of course, when watching classic films or series, such a high refresh rate doesn't matter, as these materials are made in 24 or 30 frames. Here, however, the built-in motion smoother called TruMotion comes to the rescue. Its correct manual configuration can cleverly eliminate the effects of "juddering" images, improving fluidity without creating an artificial soap opera effect. Motion clarity can also be improved using the "OLED Motion" function, also known as the BFI (Black Frame Insertion) feature, which inserts black frames between those displayed by the television. However, we do not recommend using it, as the image unnaturally stutters and flickers when this solution is employed, which ultimately strains the eyes over time.

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 G6 - Input lag
9.9/10
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.

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.
LG G6 - Viewing angles
7.2/10
Brightness drop at an angle of 45 degrees: 28%
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 G6 - Daytime performance
8.2/10
Panel finish: Glare
Reflection suppression: Good
Black levels during daytime: Very Good
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.

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.

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.

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.
