LG OLED G6 is undoubtedly one of the most anticipated releases of this year. The enormous interest primarily stems from the implementation of the new generation of Tandem OLED (2nd generation) panels, which are designed to eliminate flaws and bring improvements over last year’s G5 model. The manufacturer adds to this an updated image processor, namely the 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-world performance and whether the G6 can indeed become the TV of the year.
The retail unit for testing was lent to us by one of our viewers/readers, for which we are sincerely 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 generation 2 Tandem OLED panel, it does something that no other glossy screen on the market has managed so far – it superbly suppresses light reflections while maintaining perfect, unblemished image quality. When we add record brightness and the unique properties of the panel itself, the G6 can produce images that can literally knock you off your feet at times. The excellent webOS system and features for gamers further reinforce the belief that it 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 expectations are the highest they can be. During detailed testing, we encountered issues 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 the couch this flaw does not stand out drastically and does not negate the overall admiration for the contrast, a trained eye will easily notice that LG's engineers stumbled at the last hurdle during the panel tuning. When buying a pretty expensive flagship product right here and now, perfection is simply expected from the first turn on.
Despite this obvious blunder, the LG G6 is still absolutely at the forefront of the market and one of the most interesting televisions of this year. It has a solid foundation 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 again have nothing to look for. We promise to keep monitoring the situation continuously, and as soon as a patch appears, we will definitely verify its effectiveness.

The front of the new G6 won't surprise anyone who has been following LG's flagship models – the Koreans have simply decided that the G series is a tried-and-true design. However, they deserve credit for creating a well-crafted piece of top-tier equipment. The whole thing is enclosed in a uniformly flat case, held together by a raw, metal frame in a graphite-silver hue. It looks very good, minimalist, and thanks to that, it draws our focus to the display itself.
When purchasing this model, it’s important to pay close attention to the labels because LG traditionally splits the Gallery series into two versions. Our editorial team received a box labelled “LW”. This means that instead of classic legs, we get a dedicated mount inside. Since we didn't fancy drilling holes in the wall in the lab 😉, we had to resort to a universal VESA stand. If you plan to place the TV on a cabinet, make sure to look for the “LS” version with a central base. However, remember that the variant “LW” we tested extracts one hundred percent from this design. Once mounted, the TV literally sits flush with the wall, functioning as a modern piece of artwork.

Visibility of details in the lights:
As the LG G6 is based on OLED technology, specifically the WOLED TANDEM 2nd gen matrix, when it comes to black levels and contrast, we’re talking about perfection, which is confirmed by our lab measurements – in every test scenario, the TV achieved an absolute infinity mark. The ability to independently control each pixel gives it a significant advantage over any LCD panel on the market. This translates to a brilliant, plastic depth of image that immediately pulls you into any possible viewing experience. This is clearly visible in the example of a dark, challenging scene with a helicopter from the film Sicario 2. While traditional screens with local dimming (including Mini-LEDs) can generate an annoying “halo” effect in such moments, lighten black bars in films, or lose details in the shadows, the LG G6 handles it 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 strong grain and flickering of the image are noticeable. However, we do not take this into account when assessing the contrast itself and this part of the review – we will describe this specific issue in the further 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, best of all, this translates directly to real movie scenes. The TV flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points in the form of stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 drops due to the panel protection system (ABL). However, in real, varied movie shots, this value still hovers around an impressive 2000 nits, which can be considered a remarkable result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel has brought about only a cosmetic change, but still an improvement. The coverage of the DCI-P3 color space reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although it's important to 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 white sub-pixels (WOLED). However, in everyday content and most films, capturing 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 its high peak brightness, the LG G6 is able to reproduce HDR content with stunning director-level precision. The picture looks uncompromised: what should be bright is extremely bright, and what should be dark remains perfectly black. The TV performs excellently regardless of whether we’re watching classic HDR productions mastered to 1000 nits or those exceptionally challenging for the hardware, reaching up to 3000 nits – like the bright scenes from the film Pan. Even in such demanding conditions, details in the brightest points, such as the sun, are brilliantly rendered, and the picture does not suffer from a loss of detail.
HDR luminance chart:
Even though the LG G6 is an extremely bright television, it still gains a lot when playing content encoded in Dolby Vision with dynamic metadata. The manufacturer's brochures provide quite a bit of information about the new processor and its advanced dynamic tone mapping feature for standard HDR10. Our tests showed that this feature, in addition to 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 major issue as the television fully supports 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 photo comparison – in difficult scenes, such as horses on a white, bright meadow, the Dolby Vision format allows for the recovery and display of even more details hidden in the whites, which standard HDR10 was unable to separate correctly.

Dynamic: Dolby Vision
Factory color reproduction
7.4/10
We tested the LG G6 in the best factory mode for colour fidelity, which is FILMMAKER MODE. In the case of our test unit, this mode was reasonably well tuned straight out of the box. In SDR content, the only issue we noticed was the white balance, which leaned towards warmer tones. This made the image occasionally appear slightly yellowish, but overall, it wasn't a significant problem. The G6 performed a bit worse in HDR content. There, the white balance showed too much blue component. This caused the image to veer towards cooler shades, resulting in quite noticeable errors. As can be seen on our ColorChecker chart, the colours shifted towards these cooler registers. Nevertheless, considering the factory settings, the television presented a perfectly decent level. However, we know that OLED screens – particularly those from LG – respond exceptionally well to professional calibration, so we immediately proceeded to do just that.
Color reproduction after calibration
9.2/10
After completing a professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We were able to tune the white balance perfectly, which removed the factory's cool and warm tints from the screen. The effects are visibly clear in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does this mean? PERFECT colours, without any distortion! However, as a reviewer’s duty, we must point out how the LG G6 arbitrarily manipulates brightness, which is due to the EOTF curve's behavior. When we look at the standard synthetic graph, 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 actual, moving film scenes (EOTF in MOVIES). Then, it is clear as day that some of the smallest fragments on the screen are slightly overly brightened by the algorithm. Of course, for the average viewer, such a deviation will practically go unnoticed, but in the test of such an expensive screen, it’s worth noting – especially since we are talking about a model that has huge aspirations for the title of the best television of the year.
LG G6 - Smoothness of tonal transitions
5.5/10
Unfortunately, we arrive at the least cheerful part of this review. If we were to evaluate solely the fluidity of tonal transitions, the G6 would score high marks. The blending of colours is at a very good level, and at times it resembles what we've seen from Samsung's QD-OLED panels. This is great news because until now, unsightly, layered bands in dark shades have been the bane of WOLED panels. In this category, we would easily give a strong 8.5 out of 10.
Note: Unfortunately, the final score in this section drops significantly, and the culprit is very aggressive dithering. In dark scenes, the image literally "shakes," and in areas close to black/dark grey, the television can flicker annoyingly. We don’t 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 some sort of update. We know that LG is capable of responding quickly to negative user feedback, which can already be read online. We will keep an eye on this and will inform you in case of any improvements.
Image scaling and smoothness of tonal transitions
8.7/10
Smooth transition function
Image without overscan on the SD signal
No matter what one might say about the G6's issues with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content extremely well. All unwanted, ugly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artifacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this feature do further smooth the image, but they start to blur the real texture elements of the objects, so we recommend keeping this slider at a low level. As for the actual 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 is on par with the global leaders.

The LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The TV supports very high refresh rates of up to 165 Hz in 4K resolution, but most importantly – there are absolutely no signs of blurring on the screen. The response time of the matrix is virtually instant, ensuring that dynamic images remain perfectly sharp.

Blur (4K@165Hz):
Of course, when watching classic films or series, such high refresh rates don't matter, as these materials are produced at 24 or 30 frames. However, this is where the built-in motion smoother called TruMotion comes in handy. Its correct manual setup can cleverly minimise the effects of the "juddering" image, improving fluidity without creating an artificial soap opera effect. Motion clarity can also be enhanced with 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 this solution causes the image to shake and flicker unnaturally, which can simply strain the eyes over time.

The LG G6 is a true beast for gamers and one of the best-equipped TVs on the market in this regard. The manufacturer didn't compromise and equipped this model with 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'll get the absolute maximum performance out of them.
The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), to AMD FreeSync Premium Pro, and Nvidia G-Sync Compatible. Let's add to that a remarkably low, almost imperceptible input lag and an excellently functioning game panel (Game Optimizer), which allows you to constantly monitor 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. With a standard 120 Hz signal, the Input Lag is just 5 ms. At 60 Hz, this value increases to 13 ms, which is still excellent and completely imperceptible latency. The only thing we need to criticise is the TV’s behaviour when providing 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 these values in gaming are so low that absolutely no one will feel any discomfort during gameplay.

Chroma 444 (max. resolution and refresh rate): Yes
Font clarity: Good

As we mentioned earlier, the LG G6 offers an outstanding display for gamers as well as for casual computer users. With full support for Nvidia G-Sync and AMD FreeSync technology, as well as a high refresh rate of up to 165 Hz, this television performs brilliantly as a massive gaming monitor. However, daily office work with text looks a bit worse (though in our opinion still very good), which is a typical characteristic of every WOLED-type screen. Due to the specific arrangement of four subpixels (with an additional white subpixel), rather than three like in classic computer monitors, system fonts can have an additional, in this case red glow around black or white letters. This is directly due to the new structure of the second-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 during occasional document work or web browsing.
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. A TV viewed from the side does not lose drastically in brightness or colour saturation. In this regard, the image quality is miles better than any LCD TV – and this applies to both IPS panels and especially to VA panels that lack special wide-angle coatings. In this area, 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 to be slightly worse than last year. We noticed that the 2nd generation Tandem OLED panel tends to take on a greener hue 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
LG G6 will perform wonderfully as a television in a well-lit room. Thanks to its impressive peak brightness, the TV can easily cut through most external light sources. Best of all, the new generation of Tandem OLED panel has brought significant improvements in reducing reflections. Although the screen coating is still glossy (which helps maintain well-saturated colours even in challenging conditions), it effectively dampens glare. It does this far better than traditional OLED screens with a standard glossy coating. We could confidently compare this level to glossy QD-OLED panels, but with one key advantage for LG. Unlike the competition's technology, in this model, deep black in a bright lounge remains intact. There’s no grey or purple tint from ambient light – the black in the G6 during the day is just as perfect as it is at night.

webOS System and Smart Features
The television runs on the latest version of the webOS system. Although it is a closed platform, it supports absolutely all the key streaming apps on the market. You can also easily access useful wireless connectivity features like built-in Chromecast, AirPlay, and classic screen mirroring. However, the biggest standout feature of the LG platform is the brilliant Magic remote. While it is quite compact and lacks a physical numeric keypad, it does something that competitors still can't replicate – it functions like a wireless mouse. It is equipped with a gyroscope, allowing you to move an intuitive cursor across the screen, which dramatically speeds up entering passwords or navigating menus. Additionally, LG has one of the best voice assistants for controlling the device, and this combination with the Magic remote provides excellent capabilities for navigating the system. The only thing that can be quite irritating here is the intrusive ads and sponsored tiles, as LG increasingly clutters the main screen of the system. Despite this, the lack of Google TV is not a detriment to the G6 – considering the smooth operation of webOS, one can confidently say it is even 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, it includes a plethora of useful features. The manufacturer did not skip on the PVR function, which allows recording programs from the built-in tuners directly to external USB storage or a hard drive. We also have a smoothly functioning TimeShift for pausing live TV and a recording scheduling option. These features can prove to be a great advantage during the upcoming FIFA World Cup, when matches 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 file player (as is the case with systems based on Android) is actually not a problem for the LG G6. The built-in factory player works great and seamlessly supports most audio, video, or photo formats that we provided from our USB drive. However, during testing, we encountered some shortcomings – namely, a rather strange lack of support for subtitles in the popular .txt format. We do believe that this option will soon be available on the G6 with the next software update.

DTS-HD Master Audio
Despite its very flat body, the LG G6 sounds surprisingly good. The manufacturer has managed to pack quite decent speakers under the display that can produce a sound that is fairly “spatial” – if you can even call the limited physical capabilities of the TV that 😉. The sound is clear, has good dynamics, and is flawless for everyday viewing of news programmes or series. The TV also supports the very popular Dolby Atmos spatial audio codec without any issues.
Unfortunately, for the second year in a row, there is no support for the DTS:X format. Be that as it may, it has recently been quite unpopular in streaming services, but a premium TV in terms of price and quality, in our opinion, simply should not limit users regarding audio format support. Additionally, we have to criticise LG for somewhat downgrading the audio menu itself. We missed more advanced settings and predefined sound profiles, which were definitely more abundant in last year's model.
