LG OLED G6 is undoubtedly one of the most anticipated releases of this year. The huge interest stems primarily from the use of the new generation of Tandem OLED panels (2nd generation), which aims to eliminate flaws and introduce improvements over 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 buyer expectations. In this review, we check how these announcements translate into real results and whether the G6 can indeed become the TV of the year.
One of our viewers/readers kindly lent us a test unit, 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 aspects. Thanks to the new 2nd generation Tandem OLED panel, it does something that no other screen with a glossy coating on the market has been able to achieve – it brilliantly suppresses light reflections while maintaining perfect, unblemished image quality. When we add to this record brightness and the unique properties of the panel itself, the G6 can generate an image 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 only one side of the coin... because in a device of this class, the demands are the highest possible. During detailed testing, we encountered an issue with digital image processing in scenes close to black. We're talking about overly aggressive dithering and slight flickering of details in dark sequences. Although, during normal viewing from a couch distance, this flaw is not dramatically noticeable and does not negate the overall praise for the contrast, a trained eye will easily detect that LG's engineers stumbled on the final stretch while tuning the panel. When purchasing a quite expensive flagship product here and now, perfection is simply expected from the first start-up.
Despite this obvious mishap, the LG G6 is still at the absolute forefront of the market and one of the most interesting televisions of this year. It has solid foundations to become the ultimate screen. We deeply believe that the manufacturer will quickly diagnose the problem and release an appropriate software update – if that happens, the competition will again have nothing to look for. We promise to monitor the situation closely, and as soon as a patch appears, we will certainly verify its effectiveness.

The front of the new G6 won’t surprise anyone who follows LG's flagship models – the Koreans simply decided that the G series is a tried-and-true design. However, they deserve credit for creating a piece of solidly crafted hardware from the top shelf. The whole thing is enclosed in a uniformly flat case, held together by a raw, metal frame in a graphite-silver tone. It looks very good, minimalist, and thanks to that, our gaze is focused on the matrix itself.
However, when purchasing this model, you need to pay close attention to the markings, as LG traditionally divides the Gallery series into two versions. A box labeled “LW” arrived at our editorial office. This means that inside, instead of traditional feet, we get a dedicated mount. Since drilling holes in the wall didn’t appeal to us in the lab 😉, we had to make do with a universal VESA stand. If you plan to place the TV on a dresser, look for the “LS” version with a central base right away. However, remember that it is the version “LW” that we tested that gets one hundred percent out of this design. Once hung, the TV literally flushes with the wall and serves as a modern picture.

Visibility of details in the lights:
Since the LG G6 is based on OLED technology, specifically the 2nd generation WOLED TANDEM matrix, we are talking about perfection in terms of blacks and contrast, which is confirmed by our lab measurements – in every test scenario, the television achieved an absolute infinity mark. The ability to control each pixel independently gives it a powerful advantage over any LCD panel on the market. This translates to a brilliant, plastic depth of image that immediately draws you into every possible viewing experience. This is clearly visible in the example of a dark, demanding scene with a helicopter from the movie Sicario 2. While traditional screens with local dimming (including Mini-LEDs) can generate annoying "halo" effects in such moments, lighten black bars in films, or lose details in shadows, the LG G6 handles it flawlessly. Black where it should be black remains pitch-black and perfectly separated from bright points.
*A small note: during this test, a fairly strong grain and flickering of the image stands out. However, we do not take it into account when evaluating the contrast itself and this part of the review – we will describe this specific problem in further detail in the section: "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 best of all – this has a direct impact on real film scenes. The television flawlessly pulls out details in the bright parts 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's protection system (ABL). However, in real, varied film shots, this value still hovers around 2000 nits, which can be considered an outstanding result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel brought only a cosmetic change, but still an improvement. The DCI-P3 color gamut coverage reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although one must remember one thing: at extremely high brightness levels, the volume of colors will be lower than in QD-OLED panels from Samsung Display due to the use of a white sub-pixel (WOLED). However, in everyday content and most films, detecting 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 a high peak brightness, the LG G6 is able to reproduce HDR material with true directorial precision. The image looks uncompromising: what is supposed to be bright is extremely bright, and what is supposed to be dark remains perfectly black. The TV performs excellently regardless of whether we are watching classic HDR productions mastered to 1000 nits or those exceptionally demanding for the equipment, reaching up to 3000 nits – such as the bright scenes from the movie Pan. Even in such demanding conditions, details in the brightest points, e.g., the sun, are beautifully rendered, and the image does not suffer from a 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, you can read a lot about the new processor and its advanced dynamic tone mapping feature for regular HDR10. Our tests showed that this feature, in addition to a slight improvement in visibility of details, unfortunately artificially boosts the brightness of the entire screen – that’s 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 image comparison – in difficult scenes, such as horses on a white, bright meadow, the Dolby Vision format allows recovering and displaying even more details hidden in the whites that standard HDR10 was unable to properly separate.

Dynamic: Dolby Vision
Factory color reproduction
7.4/10
We tested the LG G6 in the best factory mode for color fidelity, which is FILMMAKER MODE. For our test unit, this mode was fairly well-tuned right out of the box. In SDR content, the only thing we could nitpick was the white balance, which leaned towards warmer tones. As a result, the image could sometimes appear slightly yellowed; however, overall, it wasn't a bothersome issue. The G6 performed a bit worse with HDR content. There, we noticed too much blue component in the white balance. This caused the image to take on cooler shades, resulting in quite noticeable errors. As can be seen in our ColorChecker chart, colors were indeed shifting towards these cooler registers. Nevertheless, for factory settings, the television displayed a completely decent level. However, we know that OLED screens – especially those from LG – respond wonderfully to professional calibration, which is why we immediately proceeded with it.
Color reproduction after calibration
9.2/10
After conducting a professional calibration, we gained complete control over the panel, and we were able to adjust all parameters to nearly zero. We managed to perfectly tune the white balance, which made the factory-cool and warm tints disappear from the screen. The effects are clearly evident in the ColorChecker test – the average color reproduction errors dropped below the critical value of 1-2. And what does that mean? PERFECT colors, with no distortion whatsoever! However, from a reviewer's obligation, we must comment on how the LG G6 autonomously manipulates brightness, for which the EOTF curve is responsible. When we look at the standard synthetic graph, it may seem that the line is quite straight. The situation changes, however, when we turn on the measurement filter, which shows how the television interprets brightness in real, moving film scenes (EOTF in MOVIES). At that point, it becomes clear that some of the smallest fragments 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 the best television of the year.
LG G6 - Smoothness of tonal transitions
5.5/10
Unfortunately, this is where we come to the least cheerful part of this review. If we were to evaluate solely the smoothness of the tonal transitions, the G6 would score high marks. The color blending is at a very good level, and at times it resembles what we know from Samsung's QD-OLED panels. This is great news because up until now, ugly, banding artifacts in dark shades have been the bane of WOLED panels. In this category, we would easily give it 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 “shivers,” and in areas close to black/dark gray, the television can be annoyingly flickering. We do not know exactly what this is due to, but looking at the tests from other reviewers around the world - everyone has encountered exactly the same problem. We hope that LG will fix this as soon as possible with an update. We know that LG can respond quickly to negative user feedback, which can already be read online. We will keep an eye on this issue 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
No matter what one may say about the G6's problems with near-black signal, it must be fairly acknowledged that it handles highly compressed material and lower resolution content brilliantly. All unwanted, ugly tonal transitions are effectively reduced here by the “Smooth Gradation” feature. On the “Low” setting, the algorithm operates flawlessly – effectively masking the artifacts resulting from strong compression, without destroying the sharpness and details in the frame. Higher levels of this feature indeed smooth the image even more, but they start to blur the real texture elements of objects, which is why we recommend keeping this slider at a low level. 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 respect, the G6 does not lag behind the world's best.

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

Blur (4K@165Hz):
Of course, when watching classic movies or series, such a high refresh rate does not matter, since these materials are made in 24 or 30 frames. However, here the built-in motion smoother called TruMotion comes to the rescue. Its correct manual configuration can very cleverly eliminate the effects of "juddering" images, improving fluidity without creating an artificial soap opera effect. Motion sharpness can also be improved using the "OLED Motion" feature, or the so-called BFI feature, which inserts black frames between those displayed by the television. However, we do not recommend using it, as using this solution causes the image to shake and flicker unnaturally, which can simply strain the eyes over the long term.

LG G6 is a true monster for gamers and one of the best-equipped TVs in this regard on the market. The manufacturer did not seek compromises and equipped 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 your PlayStation 5, Xbox Series X, or powerful PC into, you will extract the absolute maximum from them.
The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), through AMD FreeSync Premium Pro, to Nvidia G-Sync Compatible. Let's add to this the remarkably low, almost imperceptible input lag and a brilliantly functioning gamer panel (Game Optimizer), which allows you to continuously monitor the signal parameters. Gaming on this screen, with the perfect black of OLED and powerful refresh rates, is pure pleasure.
LG G6 - Input lag
9.9/10
When it comes to signal delay, the results are remarkably 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 point out is the television's behavior after receiving the Dolby Vision Gaming 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 amazing screen for gamers but also for those using computers. With full support for Nvidia G-Sync and AMD FreeSync technology, as well as a high refresh rate of up to 165 Hz, this TV will work brilliantly as a giant gaming monitor. On the other hand, everyday office work with text looks a bit worse (although in our opinion still very well), which is a typical feature of every WOLED 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 sometimes have an additional, in this case red glow around black or white letters. This is directly due to the new structure of the 2nd generation Tandem OLED matrix, which now operates in an RGWB arrangement (last year's first generation Tandem OLED used a BWRG arrangement). In our opinion, the sharpness of font edges has slightly worsened because of this, but it is definitely 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 befits an OLED panel, the viewing angles on the LG G6 are really good. When viewed from the side, the TV does not drastically lose brightness or color saturation. In this regard, the picture quality is infinitely better than in any LCD TV – and this applies to both IPS panels and even more so to VA panels without special wide-angle coatings. In this matter, the only better screens on the market remain QD-OLED panels from Samsung Display, where the angles are simply perfect, as well as older WOLED panels with MLA (microlens) technology, which LG abandoned in this series two years ago. Unfortunately, we assess the viewing angles in this year's model as slightly worse than last year's. We noticed that the 2nd generation Tandem OLED panel has a tendency to take on more greenish hues when viewed at a steep angle, 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 TV 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 Tandem OLED panels has brought significant improvements in terms of reducing glare. Although the screen coating is still shiny (which helps maintain well-saturated colors even in difficult conditions), it effectively suppresses reflections. It does this significantly better than classic OLED screens with standard glossy coatings. We could confidently compare this level to that of shiny QD-OLED panels, but with one key advantage for LG. Unlike the competition's technology, the deep black in a bright living room remains intact in this model. There is no sign of grayness or purplish tints due to incoming light – the black in the G6 during the day is simply perfect, just like it is at night.

webOS System and Smart Features
The TV runs on the latest version of the webOS system. Although it is a closed platform, it supports absolutely all the key streaming applications on the market. You can also easily access useful wireless connectivity features, such as built-in Chromecast, AirPlay, or classic screen mirroring. However, the biggest distinguishing feature of LG's platform remains the brilliant Magic remote. Although it is quite compact and lacks a physical numeric keypad, it does something that competitors still can't replicate – it works like a wireless mouse. It is equipped with a gyroscope, allowing us to move an intuitive cursor across the screen, which drastically speeds up password entry and navigation through the menu. Additionally, LG has one of the best voice assistants for device control, and this combination with the Magic remote offers great possibilities for smoothly navigating the system. The only thing that can be quite annoying here is the intrusive ads 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 – given the smooth operation of webOS, it can even be considered an advantage.
Features for Traditionalists
In terms of traditional television, the LG G6 also performs excellently and does not forget about traditional users. Despite the minimalist remote, there are plenty of useful solutions on board. The manufacturer has not given up on the PVR function, which allows for recording programs from built-in tuners directly to external USB storage or a hard drive. There is also an efficiently working TimeShift for pausing live television and the option to schedule recordings. These features may prove to be a perfect fit during the upcoming World Cup matches when games will be played late in the evening and we may not be able to watch them live. Of course, standard features are also included, such as the ability to connect wireless headphones via Bluetooth.

The inability to install an external media player (as is the case in Android-based systems) is actually not a problem for the LG G6. The factory-installed media player works great and seamlessly supports most audio, video, or image formats that we provided from our flash drive. However, during testing, we encountered some shortcomings – specifically, a rather strange lack of support for subtitles in the popular .txt format. However, we believe that this option will quickly be added to the G6 with the next software update.

Despite its very flat design, the LG G6 sounds surprisingly good. The manufacturer managed to squeeze quite nice speakers under the display, capable of producing a rather "spatial" sound – if you can even call the limited physical capabilities of the TV that 😉. The sound is clear, has decent dynamics, and is suitable for everyday viewing of news programs or series without any issues. The TV also easily supports the very popular Dolby Atmos surround sound codec.
Unfortunately, for the second year in a row, it lacks support for the DTS:X format. Regardless of what one might say, it has recently become quite unpopular in streaming services, but a top-of-the-line TV in terms of price and quality simply should not limit users in handling audio formats, in our opinion. Additionally, we have to criticize LG for somewhat downgrading the audio menu. We missed more advanced settings and predefined sound profiles, which were definitely more abundant in last year's model.
