Philips OLED820 vs Philips MLED920 / MLED910

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel that we find in its biggest competitors – LG C5 or Samsung S90F. This means we can count on truly solid performance. This year, mid-range OLED panels are capable of exceeding the threshold of a thousand nits, and the model tested reaches around 1300 nits in some films. This is an outstanding result that allows for an extremely precise depiction of the director's vision, as contemporary productions are mastered in such brightness ranges. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the movie The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and wide coverage of the DCI-P3 color gamut at 99% make the picture simply look great.

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 color reproduction in the factory settings really surprised us, and positively so. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of color. The white balance was relatively accurate, though with a slight lack in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a flaw that particularly interferes with everyday viewing. A larger problem arose with the brightness characteristic. The gamma chart clearly deviated from the ideal, with the line being below the expected values, causing the image to be overly brightened, and the colors looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

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.

After calibration, both the Filmmaker mode and the game mode gained quite a lot. A slight adjustment of the white balance and an improvement in brightness characteristics resulted in excellent outcomes for SDR content – the image looked almost perfect, natural and very close to the reference. In the case of HDR materials, the situation was similar; the colors looked stunning and it was hard to find anything to criticize. However, we noticed a certain feature that we had already pointed out when comparing scenes from the movie Billy Lynn. An analysis of the EOTF curve revealed that the television has a slight tendency to dim details in the blacks, which means that the darkest sections are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is remarkable, and the OLED820 stands out as one of the more interesting screens in its class. It just needs a little bit of fine-tuning, and there's really nothing to be afraid of.

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.

Fortunately, the earlier effects of the aforementioned posterization can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted color banding, improving the smoothness of tonal transitions. It does happen, however, that it works a bit too aggressively and smooths out some details – such as minor skin imperfections of the actors – but despite this, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be alleviated by slightly increasing the sharpness in the picture menu – it’s a matter of personal preference. The lack of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

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.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard television sources or consoles, where 120 Hz is used, the motion is fast, sharp, and simultaneously smooth, without traces of ghosting. This is thanks to the outstanding response time between pixels, which ensures the image retains clarity in every dynamic scene. The manufacturer has also added its own smoothing feature called "Motion Style." In the menu, we find two sliders – the first, responsible for fluidity, allows us to adjust the amount of artificially added frames in movies. This way, we can choose a raw, cinematic character with a clearly visible film frame or a more theatrical image with smooth motion. The second slider is for reducing blurring, especially useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

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.

Philips OLED820 is one of the most complete televisions for gamers. It practically has everything you could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (too bad there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television also handles lower resolutions at 120 Hz without any issues, so you can count on great flexibility when choosing different picture modes on the console. Philips also adds Game Bar – a panel that allows you to change picture modes, add a crosshair, or view parameters. Although it looks quite clunky and is less polished than that of the competition, it serves its purpose. In practice, therefore, the OLED820, besides having a full set of four HDMI 2.1 ports, offers almost everything a gamer might need.

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.
