Philips MLED920 / MLED910 vs LG OLED G6 (G64LW, G66LS)

In our measurements, the Philips MLED920 achieved even around 900 nits in static tests, which is a really solid result for a mid-range TV. In practice, this translates to a lot of satisfaction during viewing sessions – in scenes rich in bright light, such as the first, third, or fifth test screens, the screen was able to generate about 700 nits, which is enough to feel the true "HDR effect." However, it cannot be denied that the limited number of backlighting zones and the compromises of mini-LED dimming algorithms in more demanding scenes reveal their nature. In sequences with small light sources – such as the moon or a scene from the movie Sicario 2 – the television clearly prioritizes maintaining deeper blacks at the expense of the brightness of those small elements. For most viewers, this is still a reasonable compromise, as the dark background tends to look much better, though one must be aware that the details themselves may not impress with intensity. There is also some disappointment regarding colors. Although the applied PFS filter (the equivalent of quantum dots known from QLEDs) does its job and colors appear quite vivid, the coverage of the DCI-P3 color space reaches "only" 90%. In everyday viewing, this will be sufficient, but in extremely colorful productions – such as the latest Disney animations – one can notice that some tones are not as vibrant as they could be in other constructions.

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.

Like every Philips television we tested, we primarily evaluated the MLED920 in Filmmaker mode – this is supposed to be the "most honest" mode, designed for films and to faithfully convey the creators' intentions. Indeed, in terms of colorimetry, it performs the best among all the modes available on the television, but it is not without its flaws. The first thing that stands out is the white balance. The image has a slight tendency to take on purple-pink tones, which gives it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just look at the gamma or EOTF graphs to see that the line deviates significantly beyond the norm, falling below the value of 1.8. In practice, this means "clipping" the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds to calibration, and with a few adjustments, the image quality can be significantly improved.

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.

After calibration, we managed to largely tame the white balance – to the extent that the average viewer will not be able to detect color inaccuracies. The characteristic pink-purple glow that previously disturbed the naturalness of the picture has also disappeared. The color palette has been organized, and the colors appear more consistent and neutral. The gamma in SDR content after calibration looks really good – there's no sign of the earlier “bleeding” effect in bright scenes. The picture has become more contrasted and devoid of the milkiness that previously spoiled the perception significantly. In the case of HDR content, the improvement is also noticeable, although it is still evident that the television is “doing its own thing.” The EOTF curve cannot be fully shaped, as Philips simply does not provide tools in its settings that allow for precise control over this parameter. In many films, the television simply still showcases the image “in its own way.” Despite these limitations, calibration has brought quite a lot of good – it has managed to minimize most of the color inaccuracies and significantly improve the overall balance of the picture. However, it must be remembered that certain barriers arise from the very hardware construction and they simply cannot be overcome.

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.

The manufacturer equipped this model with several features that improve signal quality, and although we usually approach such "enhancers" with skepticism, they turn out to be really helpful here. The key option is called "distortion reduction" – it works best at a medium level because, on one hand, it effectively smooths out unwanted banding and color transitions, while on the other, it doesn't excessively cut details, which keeps the image looking natural.

The situation is a bit worse with upscaling. Lower quality materials – such as test videos with models – appeared soft and lacking in sharpness. Yes, this can be somewhat corrected with the sharpness slider in the menu, but the effect still remains far from what competitors in a similar price range offer. Philips therefore still needs to work on this aspect because, in light of the successful improvement of tonal transitions, the upscaling simply performs poorly.

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 Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn’t complain about motion smoothness. And indeed – the motion blur is relatively low here for a VA panel, and although one might occasionally notice slight issues on darker backgrounds, they are not something that most people would notice during regular viewing.

A major plus is the presence of a motion smoother called "Motion Style." It allows you to adjust the smoothness to your own preferences – if someone prefers a more “theatrical,” almost television-like image, they can increase the sliders, and if they want to preserve the natural “jitter” of a cinematic frame, they just need to set lower values. This way, everyone can find the perfect balance.

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.

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that today is considered standard in televisions designed for consoles and PCs. It features ALLM, so the console automatically switches the screen to game mode, it has VRR and 144 Hz refresh rate, which guarantees smooth gameplay even in fast titles. All key HDR formats are supported – including HGiG and Dolby Vision Gaming for Xbox – which means that regardless of what you are playing and on which console, the TV will be able to extract maximum potential from the image. In everyday gaming, the Game Bar also proves to be useful – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, turn on VRR, or adjust details without leaving the game. It may not be as advanced as the competition's offerings, but it performs its job flawlessly. And lastly, something that distinguishes Philips from its competitors – Ambilight. The three-sided LED backlighting can make a huge impression in games, especially in the evening. It also provides a way to slightly "expand" the screen and feel greater immersion. And since colorful LEDs have recently become almost a mandatory element of a gamer’s room, the MLED920 fits into this trend perfectly.

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.
