Philips MLED920 / MLED910 vs LG OLED B6

Philips MLED920 in our measurements in static tests even reached around 900 nits, which for a mid-range model is quite an impressive result. In practice, this translates to a lot of satisfaction during viewing – in scenes rich in bright light, such as the first, third, or fifth test patterns, the screen was able to generate around 700 nits, which is sufficient to feel the real "HDR effect". However, it cannot be denied that the limited number of backlight zones and the typical mini-LED compromises in dimming algorithms reveal their flaws in more demanding scenes. 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 much better, although it should be noted that the details themselves may not dazzle with intensity. The question of colours also leaves a bit to be desired. Although the employed PFS filter (the equivalent of quantum dots known from QLEDs) does its job and the colours appear quite vibrant, the coverage of the DCI-P3 colour space 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 vivid as they could be in other constructions.

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 LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, 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 is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

Like every Philips TV we've tested, the MLED920 was primarily assessed in Filmmaker mode – the so-called "most honest" mode, designed for films and to faithfully convey the intentions of the creators. Indeed, in terms of colour accuracy, it performs best among all the modes available on the TV, but it is not without flaws. The first thing that stands out is the white balance. The image has a slight tendency towards purple-pink tones, giving it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just looking at the gamma or EOTF charts reveals that the line deviates significantly 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 to calibration, and with a few adjustments, image quality can be significantly improved.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover 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 colour inaccuracies. The characteristic pink-purple glow that previously disrupted the naturalness of the image has also disappeared. The colour palette has been organised, and the colours appear more cohesive and neutral. The gamma in SDR content looks really good after calibration – there’s no sign of the earlier “bleeding” effect in bright scenes. The image has become more contrasty and free from the milky effect that previously severely affected the viewing experience. In the case of HDR content, the improvement is also noticeable, although here it is still evident that the television goes “its own way”. The EOTF curve cannot be fully adjusted, as Philips simply does not offer tools for precise control of this parameter in its settings. In many films, the television still exposes the image “in its own way”. Despite these limitations, calibration has brought a lot of good – the majority of colour inaccuracies have been minimised and the overall image balance has significantly improved. However, one must remember that certain barriers arise from the very hardware construction and simply cannot be overcome.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially 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 “enhancers” with caution, here they prove to be really helpful. The key option is called “distortion reduction” – it works best at a medium level because, on one hand, it effectively smooths out unwanted steps and colour transitions, and on the other, it doesn’t excessively cut details, meaning the image still looks natural.

It’s a bit worse when it comes to upscaling. Lower quality materials – such as the test video with the model – appeared soft and lacking sharpness. Of course, it can be partially adjusted with the sharpness slider in the menu, but the result still falls short compared to what competitors offer at a similar price. Philips still needs to work on this aspect because, in light of the successful improvement of tonal transitions, the upscaling simply comes off weak.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn’t complain about motion smoothness. And indeed – for a VA panel, the motion blur is relatively low here, and while you can sometimes notice slight issues on darker backgrounds, they’re not something that will catch the eye of most people during regular viewing.

A big plus is also 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 character of the image, they can increase the sliders, and if they want to maintain the natural “judders” of a cinematic frame, they just need to set lower values. This way, everyone can find a happy medium.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get 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 now considered standard in televisions for consoles and PCs. It has ALLM, so the console automatically switches the screen to game mode, there’s VRR and a 144 Hz refresh rate that ensures 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’re playing and on which console, the television will be able to extract the maximum potential from the image. In everyday gaming, the Game Bar proves useful too – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, enable VRR, or adjust details without leaving the game. It’s not as elaborate as the competition, but it does its job without any complaints. And finally, something that sets Philips apart from the competition – Ambilight. The three-sided LED backlighting can make a huge impression in games, especially in the evening. It’s also a way to slightly 'expand' the screen and create a greater sense of immersion. And since coloured LEDs have recently become almost an essential element of a gamer’s room, the MLED920 fits perfectly into this trend.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.
