Philips MLED920 / MLED910 vs LG OLED B6

Philips MLED920 in our measurements in static tests even reached around 900 nits, which is really a solid result for a mid-range model. 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 slide, the screen managed to generate about 700 nits, which is sufficient to feel the true "HDR effect." However, it cannot be denied that the limited number of dimming zones and the compromises typical of mini-LEDs in more demanding scenes reveal their nature. In sequences with small light sources – like the moon or a scene from the film Sicario 2 – the television clearly prioritises maintaining deeper blacks at the expense of the brightness of these small elements. For most viewers, this is still a reasonable compromise, as the dark background looks significantly better, though it is important to be aware that the details themselves may not impress with their intensity. There is also a certain sense of dissatisfaction regarding the colours. Although the applied PFS filter (the equivalent of quantum dots known from QLEDs) does its job and the colours appear quite vivid, the coverage of the DCI-P3 palette reaches “only” 90%. In everyday viewing, this will be sufficient, but in extremely colourful productions – like the latest Disney animations – one can notice that some tones are not as vibrant as they could be in other setups.

The LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year’s B5. That’s down to the new, budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR look fuller in many scenes than on last year’s lower‑end OLEDs. That does not mean the B6 has no limitations. In very bright shots, when a large part of the screen is strongly lit, brightness can fall below 400 nits. This behaviour is typical for OLED TVs, especially in this segment, and that’s where you see the biggest difference compared with more expensive models. Even so, we judge the B6’s results as genuinely solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that films truly feel like a step up from ordinary SDR. Colour gamut Using the OLED SE panel has had a slight impact on wide colour gamut coverage. Compared with last year’s model the results have fallen by a few percentage points. It covers roughly 96% of DCI‑P3 and about 71% of BT.2020. That doesn’t mean the colours on the LG B6 are weak. In most films and series they look lively, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD‑OLED panels. This stems from the WOLED panel structure. Besides red, green and blue subpixels it also uses a white subpixel, which helps to boost brightness. However, this comes at a price. At very high luminance some colour is effectively 'diluted' by the white light, so the saturation of certain colours can be slightly lower. In everyday use this isn’t a major issue, but in the most demanding scenes you can notice it.

Like every Philips television we tested, we primarily assessed the MLED920 in Filmmaker mode – this is meant to be the "most honest" mode, designed for films and to faithfully convey the intentions of the creators. Indeed, in terms of colour reproduction, it performs the best among all the modes available on the television, but it is not without flaws. The first thing that catches the eye is the white balance. The image has a slight tendency towards purple-pink tones, which gives it a somewhat unnatural character. An even bigger problem, however, turned out to be what we mentioned earlier – image blooming. Just looking at the gamma or EOTF charts reveals that the line significantly deviates from the norm, dropping below a value of 1.8. In practice, this means "bleeding" of the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds well to calibration, and with a few adjustments, one can significantly improve the viewing experience.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes produce very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is, in any case, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. On SDR material the factory settings perform really well. Colour errors are small, the gamma response is correct, and the picture during normal viewing looks natural and does not feel overly "pumped up". It's a bit worse with HDR. When such content is played you quickly see that the white balance hasn't been set perfectly. Too much blue and red gives the image a slightly pink tint. This is also confirmed by colour gamut measurements and the ColorChecker, where samples clearly shift in that direction. It's not a flaw that completely spoils the picture, but it is noticeable with HDR films. Therefore anyone who wants the most faithful image should consider calibration, which we cover further on 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 distortions in colours. The characteristic pink-purple haze that previously disrupted the naturalness of the image has also disappeared. The colour palette has been organised, and the colours appear more coherent and neutral. The gamma in SDR content post-calibration looks really good – there is no longer any mention of the previous 'bleeding' effect in bright scenes. The image has become more contrasty and devoid of that milkiness which had previously greatly harmed the viewing experience. In the case of HDR content, the improvement is also noticeable, although here it is still evident that the television is going 'its own way'. The EOTF curve cannot be fully shaped, as Philips simply does not offer the tools to allow precise control over this parameter in its settings. In many films, the television still exposes the image 'in its own way'. Despite these limitations, the calibration has delivered quite a bit of good – most of the colour distortions have been minimised, and the overall balance of the image has significantly improved. However, it must be noted that certain barriers stem from the very design of the hardware and simply cannot be overcome.

During calibration, we concentrated mainly on HDR content, because that's where the factory settings needed the most correction. We did not, however, neglect SDR mode, which after adjustment was brought almost to perfection. Colours are very accurate, and brightness is controlled as it should be. The biggest improvement in HDR came from fixing the white balance. Removing the excess red and blue eliminated the pinkish tint, and the image became much more natural. Skin tones, whites and all colours that had previously shifted towards pink 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. So the LG B6 can deliver a very accurate picture, particularly for the manufacturer's entry-level OLED model.

The manufacturer has equipped this model with several features that improve signal quality, and although we usually approach such "enhancements" with caution, here they prove to be really helpful. The key option is called "distortion reduction" – it works best at a medium level, as on one hand it effectively smooths out unwanted stair-stepping and colour banding, while on the other it does not excessively cut out details, allowing the image to still look natural.

Things are a bit worse with upscaling. Lower quality materials – such as the test video with the model – appeared soft and lacking in sharpness. Indeed, it can be partially corrected with the sharpness slider in the menu, but the effect remains far from what competitors in a similar price range offer. Philips therefore still needs to work on this element, as compared to the successful improvement of tonal transitions, the upscaling simply falls short.

The LG B6 handles lower-quality material very well. This is largely thanks to effective digital image processing, which can mask some of the source’s imperfections without overly smoothing the whole scene. The "Smooth Gradation" function proves particularly useful. It noticeably reduces posterisation, especially in dark parts of the image. The safest choice remains the Low or Medium setting. The function still effectively smooths out unsightly tonal banding, but does not yet interfere too much with fine details. Purists can of course leave it switched off. Upscaling to 4K also performs very well. Full HD and 720p material retain a good amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations only become apparent with very poor sources below 720p, where the smallest text and fine elements are not always perfectly sharp, but this applies to 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 for a VA panel, and although slight issues can sometimes be noticed on darker backgrounds, they are not something that would stand out to most people during regular viewing.

Another significant advantage is the presence of a motion smoother called “Motion Style.” It allows you to adjust the sensation of smoothness to your own preferences – if someone prefers a more “theatrical,” almost television-like image, they can increase the sliders, whereas if they prefer to maintain the natural “jumps” of cinematic frames, it’s enough to set lower values. This way, everyone can find their golden mean.

One of the biggest advantages of OLED panels is the very fast pixel response time. This keeps the picture sharp and free of the visible smearing often seen on LCD TVs. However, there is a downside. During slow camera pans motion can look choppier than on LCD screens, where some of that effect is naturally masked by the slower panel. Fortunately, on the LG B6 this can be easily mitigated using the TruMotion system. With the motion smoothing set correctly you can achieve smoother motion without giving the picture an exaggerated soap opera effect.

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that is considered standard in televisions designed for consoles and PCs today. It features ALLM, so the console automatically switches the screen to game mode, alongside VRR and a refresh rate of 144 Hz, which guarantees smooth gameplay even in fast-paced 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 television will be able to extract the maximum potential from the image. The Game Bar also proves useful in daily gaming – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, enable VRR or adjust settings without leaving the game. It may not be as comprehensive as the competition, but it performs its task flawlessly. And finally, something that sets Philips apart from the competition – Ambilight. The three-sided LED backlighting can create a huge impression in games, especially in the evening. It's also a way to slightly 'extend' the screen and enhance the feeling of immersion. And as colourful LEDs have recently become almost a mandatory element of a gamer’s room, the MLED920 fits into this trend perfectly.

LG OLED B6 has plenty to offer gamers; it’s simply a complete base for PS5, Xbox Series X/S or a capable PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can avoid irritating cable swapping when connecting several newer devices at once. It offers a full suite of synchronization technologies, from standard VRR to G-Sync and FreeSync. The screen synchronises the refresh rate seamlessly with the frame output from the console or graphics card. Of course it includes ALLM: the B6 automatically recognises when a game is running and immediately reduces latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG standard means that, after initial calibration in the console settings, the image won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on the cake is the Game Bar. Instead of digging through the full menu during gameplay, a single click is enough to adjust shadow visibility, tweak selected parameters or simply check the current display mode. All of this makes the LG B6 an excellent choice for gamers.
