Philips OLED770 vs Philips MLED920 / MLED910

The Philips OLED770 does not attempt to compete with the brightest OLEDs on the market, and it would actually be hard to expect that, as it is the lowest model in Philips's series for 2025. In our measurements, it achieved a maximum brightness of about 700 nits, which allows for enjoyment of HDR effects in scenes where light appears point-wise – for example, in the flash of headlights or a starry sky. In such moments, the picture can truly impress. However, it is different when there are more bright elements on the screen. The television, like many cheaper OLEDs, limits brightness in those cases, and the entire picture noticeably dims. This was best seen in a scene from the movie The Meg, where the sun rises behind an oil rig – at that point, the brightness dropped to about 250 nits, nearly three times less. The HDR effect remains visually pleasing, but it is worth being aware that this model performs best in scenes with less intense light. Fortunately, the OLED770 has an ace up its sleeve – the coverage of the DCI-P3 color palette is as high as 99%, so colors in movies and games are saturated and very close to what the creator intended to convey.

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 first measurements already show that the factory settings of the Philips OLED770 have a lot to improve even in Filmmaker mode. The white balance chart clearly shows a lack of blue, which gives the image a slightly yellowish tint. In practice, the white is not snow-white, but leans towards warmer hues – which some may even like, but from the accuracy perspective, this is a deviation from the norm. The gamma, on the other hand, tends to be on the darker side – the average value is about 2.6 instead of the reference 2.4. In the mid-tones, the image appears muted and more saturated, which may look too "filmic," but takes away some naturalness. However, the biggest issues can be seen in color reproduction. The average error is relatively high, and some colors – especially shades of gray – clearly deviate from what should be seen. In everyday viewing, this means that sometimes colors may look less natural than we would wish.

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.

Philips OLED770 has shown signs from the beginning that it houses significant potential, but it was difficult to fully see this in the factory settings. The image was sometimes too warm, and some colors seemed to have lost their naturalness along the way. However, calibration revealed that it is a television very receptive to adjustments – it reacted to every correction and almost immediately unveiled another layer of its capabilities. The white balance was successfully set both in SDR and HDR, eliminating the yellowish glow and presenting a neutral, clear white. Gamma stabilized closer to perfection, allowing midtones to regain their naturalness, and shadows no longer appeared artificially darkened, possibly even with a slight brightening effect. The effect was obvious... Movies are watched with greater ease; the image has cinematic depth, but without the feeling that something is exaggeratedly darkened. However, the most interesting part was the work on colors. Out of the box, the errors were not dramatic but slightly noticeable – skin tones were sometimes too warm, and gray didn’t always have the shade we expected. After calibration, the error values dropped to around 2, and in many cases even below 1. This is a level significantly lower than the threshold of perception for the human eye. In other words, after correction, the colors finally “clicked” into place. Looking at the screen, we had the impression that the television had begun to speak with a full voice. Like an instrument that has finally been well-tuned.

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.

The problem of the previously mentioned color connections can largely be mitigated by the "distortion reduction" feature, which is an algorithm for smoothing tonal transitions in Philips TVs. It works best at a low setting—effectively eliminating unwanted color bands while not introducing strange artifacts or losing image detail. It's one of those features that is truly worth keeping switched on.

The issue with upscaling is somewhat less favorable. The image from a lower resolution can be too soft, while at the same time, distinctive "jaggies" appear in certain areas. The impression is that the algorithm is trying to reconcile two contradictory directions—smoothing and sharpening—and ultimately hasn't found the golden mean. As a consolation, it's worth noting that the television has no issues with overscan, meaning it doesn't cut off the edges of the image, which sometimes happens with other competing models.

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 issue of the panel in the Philips OLED770 is not entirely straightforward. The manufacturer claims a 120 Hz panel, but our measurements showed that the screen can accept a 4K signal even at 144 Hz. This sounds like great news – because who wouldn't want an extra mode for PC gaming at this price? However, the reality turned out to be more complex. With 120 Hz materials, the television behaves like most OLEDs – the picture is absolutely clear, with no trace of ghosting or blurring, making it ideal for both fast-paced games and sports broadcasts. The problem arises only at 144 Hz. Unlike models with official support for that frequency, here we observe the phenomenon of so-called frame skipping. This means that the television is unable to display all frames – some of them are skipped, causing the motion to lose fluidity, and double outlines appear on the screen. The effect resembles the operation of the BFI function, which Philips does not offer in this model anyway.

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.

If someone is looking for a gaming TV, the Philips OLED770 is a candidate that's hard to ignore. The mere fact that we have an OLED here provides a great starting point – perfect blacks and infinite contrast make evening sessions in atmospheric games look like they’ve been pulled straight from the cinema. On top of that, there’s the Ambilight system, which features LEDs on the back of the TV that extend the image onto the wall behind the screen. The effect is such that even regular gameplay in FIFA can look like a small spectacle, and in horror games, the atmosphere becomes really intense. On the technical side, it’s pretty good as well. The Philips OLED770 supports Variable Refresh Rate (VRR) up to 120 Hz, has an automatic low latency mode for gamers (ALLM), and if someone is using an Xbox Series X, they can also count on Dolby Vision support in games. You just need to know that in this mode, input lag is slightly higher than standard, although still at an acceptable level. As a bonus, we get the “Game Bar” panel, which is a special tool strip for gamers. It's not the most conveniently designed solution, but it allows you to check key parameters without leaving the game. In total, this presents a picture of a TV that on one hand has all the most important gaming features, and on the other can add something unique – Ambilight. And it’s this mix of technology and visual effect that makes the OLED770 one of the better screens for gaming in a home environment.

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.
