Philips MLED920 / MLED910 vs LG OLED B6

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 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.

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 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 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.

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.

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.

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.

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.

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.

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 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.
