Philips OLED910 vs TCL C8L / QM8L

OLED910 is simply an absurdly bright television for an OLED. All thanks to the new panel from LG Display, the Tandem RGB OLED, which Philips has branded as "META OLED". It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unachievable in OLEDs. The way the television handles full-screen scenes flooded with bright light also deserves high praise. Usually, in OLEDs, brightness drops significantly, but here it remains at a great level – around 1400 nits. These values are almost reference-level, and combined with excellent colour reproduction at 99% DCI P3 and 82% BT.2020, it gives us an HDR effect that can confidently be called one of the best in the world.

When it comes to HDR, the TCL C8L turns out to be a hellishly bright television – and I mean that literally. On a synthetic test pattern of 5%, our measuring equipment indicated a result exceeding 4500 nits. That's an almost cosmic result, considering that reference director's monitors, which we often refer to in our materials, usually operate around 4000 nits. Does this mean the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not quite. Dry synthetic tests are one thing, and real film images are another. In real, varied scenes, the C8L hits around 1600 nits at its peak. That's still a very good result, ensuring a very high level of HDR dynamics, but it's clearly lower than what the manufacturer boasts in the specifications. The trouble begins with very small bursts of light – then the brightness can drastically drop to around 600 nits. The algorithm does everything it can to maintain deep blacks and minimise halo effect, but it does so at the cost of HDR impact. This is ideal evidence that laboratory test patterns rarely correlate with what we ultimately see on the screen.

Huge applause is due for colour reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the jaw-dropping measurements come from the notoriously demanding BT.2020 space. The C8L achieves an impressive 90% in this area, placing it alongside today’s top screens that feature RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene being displayed. Of course, it’s important to remember that content mastered for such a wide gamut in films or series is still a rarity. However, the very fact that the panel has such a "reserve of colours" deserves huge admiration.

Update 01/2026

After conducting a series of calibrations of the OLED910 model with our clients, we noticed that the measurement results differ from those obtained during the initial tests. The factory tuning of the film mode proves to be significantly better than our first tests indicated. The white balance is set very precisely, with only a minimal red dominance. The factory colour reproduction holds close to reference standards – average Delta E errors hover around 3-4, which is an excellent result for factory settings. However, there is some concern about how the television manages brightness. Analysis of the Gamma (SDR) and EOTF (HDR) graphs shows a tendency to excessively "pull" details from the shadows. In practice, this means that the image can appear too bright, resulting in a loss of black depth in favour of visible details that should remain hidden. Of course, this effect can be effectively corrected during professional calibration.

Unfortunately, when it comes to colour reproduction straight out of the box, in Filmmaker mode the OLED910 performs really poorly. The television excessively highlights the blue colour, and at times it looks almost like a store mode. This gives the impression that the manufacturer hasn’t quite tuned the device well. The result is that colours appear unnatural, and the overall effect resembles a somewhat exaggerated display setup in a market. HDR content presents much better, where apart from a slight loss of details in the blacks, there’s not much to complain about. The problem is that in everyday viewing, it’s actually SDR material that matters most – and on the OLED910 it simply looks poor and falls far short of what we would expect from a television of this class.

We tested the TCL C8L in the best factory mode available in the TV's menu for picture fidelity. I’m of course talking about Filmmaker Mode, which was introduced into this brand’s software relatively recently (a year ago in the K series). Thanks to it, the average user can get pretty good colour reproduction straight out of the box, although it’s certainly not perfectly tuned. Looking at the factory white balance of our unit, in both SDR and HDR content, there was a clear lack of the red component, which made the picture noticeably cooler and slightly shifted towards bluish‑green hues. The issue of brightness management is also ambiguous, as we mentioned earlier. While in SDR content the linearity of the gamma parameter is really good and consistently holds the reference value of 2.4, things are much worse in HDR. Tracking the EOTF curve clearly shows the TV’s brightness is considerably boosted across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that is in a mode that by definition should avoid this. Of course, like every unit in our lab, this one was also subjected to professional calibration, and you can find the results below.

Fortunately, it quickly turned out that it wasn't the panel causing the problems, but the way Philips factory-tuned the OLED910. After calibration, the television showcased its full potential, and only then could we see what the new panels from LG Display were truly capable of. We primarily corrected the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural look. The final effect can be described as excellent. Errors on the Color Checker palette rarely exceeded a value of 3, which in practice means an image close to ideal and colours presented in line with the creators' intent. In SDR content, the effect was stunning, and in HDR, the improvement was even more noticeable – gradients became cleaner, and colours fuller and more accurate. After calibration, the OLED910 transformed from a disappointing television into equipment that can be confidently referred to as reference-grade in terms of colour accuracy.

As you can see, the results of a professional calibration of the TCL C8L are genuinely promising, thanks to the extensive adjustment tools the manufacturer made available in the menu. Most importantly, we were able to fully correct the white balance, eliminating a lack of red so the image finally stopped drifting into unwanted, cool tones. After this step, errors in the ColorChecker test fell to near-reference values, regularly sitting below a Delta E threshold of 2, which is under the level noticeable to the human eye.

Since the test patterns look so perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with real film material (I recommend turning the EOTF filter on when watching films), it becomes clear that the TV in most scenarios still responds to HDR metadata in its own way. As a result, the image can be a touch too bright and not in line with the creators' intent, and it was precisely for this lack of repeatability with real-world films that we had to dock the C8L a few points.

The previously visible colour connections can be largely mitigated thanks to a feature called "distortion reduction." Similar to the OLED820, it’s best to set it to medium level, as it then provides quite decent results – smoothing unwanted tonal transitions while not taking away too many details from the image. Although at times the effect may be a bit too aggressive, in everyday viewing, this function can be considered useful.

When it comes to image scaling, the OLED910 performs really well. The test material with the model showcased a characteristic soft look typical of Philips – at times almost too soft – but at any moment this can be adjusted with the sharpness slider to tailor the image to your own preferences. It’s also a plus that the television has no issues with overscan, which still occurs in some competitors' models. It’s a minor detail, but it’s pleasing as it means that all content, even the oldest, is displayed as it should be.

This year the C8 series and the higher-end models have probably received the biggest and most eagerly awaited upgrade in TCL's history, and it's to do with digital image processing. The C8L is the entry-level model in the manufacturer's line-up to be fitted with the latest flagship MediaTek Pentonic 800 chipset (shown in the menu as MT9655). It is thanks to its processing power that the feature called "Gradual Smoothing" finally works the way it should. The algorithm effectively removes unwanted posterization (ugly tonal transitions / colour banding) from the picture, doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although judging this element can be purely academic, because the differences between today's TVs in this class are very subtle. The most important point is that TCL finally has nothing to be ashamed of compared with the competition.

OLED910 is a TV with a refresh rate of 144 Hz. It’s a bit of a shame that Philips didn’t opt for 165 Hz, as we know that the matrix used in it is capable of that. On the other hand, such a bonus will mainly benefit PC gamers, as for everyday use, the most important thing is the 120 Hz refresh rate, which is fully sufficient. Combined with the advantages of the OLED matrix – lightning-fast pixel response times and the absence of motion blur, the picture is impeccably sharp and fast, even in dynamic action scenes. The traditional motion smoother from Philips called “Motion Style” also deserves praise. We can easily adjust it to our own preferences: the “Smoothness” slider is for movies and allows you to choose between a more “framey,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports; here, it’s worth setting it to the maximum value so that the image is clear and sharp during very fast shots.

The TCL C8L is equipped with a fast panel with a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, relying on consoles or TV broadcasts, will use a steady 120 Hz. And it is at 120 Hz that the motion-processing algorithms take care of image processing for films, series and sports. In the TV's menu you'll find a "Motion Clarity" option that lets you customise the motion smoothing to your preferences. The algorithms handle both cinematic productions at 24 or 30 frames per second and fast-paced sports broadcasts at 50 or 60 frames per second, maintaining the right level of smoothness.

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they'll easily make the most of that potential. For consoles, the most important thing is still 120 Hz, and everything works smoothly here. It has VRR, an automatic game mode, and even Dolby Vision in games along with HGiG mode, so we pretty much get a full package of gaming features. Philips also added a Game Bar, which is like a quick menu that shows basic information and allows you to enable a few handy features. It might not look as modern as the competition, but it works and does its job. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing in this class of television. If someone connects two consoles and something extra to the eARC - like a soundbar (which doesn't really make sense in this model, but more on that in the sound section), they'll have to do a bit more figuring around. Other than that, though, the OLED910 has everything we expect from a gaming TV.

For gamers – especially for owners of powerful PCs and multiple consoles simultaneously – the TCL C8L is a true beast. This is the first model in this manufacturer's lineup that is equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly due to the use of the new Pentonic 800 processor, which we've mentioned before. Additionally, the TV seamlessly supports practically every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels, as well as full variable refresh rate (VRR) operating in an impressive range of up to 288 Hz. It also supports standards such as G-Sync and FreeSync from Nvidia and AMD. When it comes to image display standards, there are no compromises either: the C8L offers complete support for HDR formats in gaming, including gaming Dolby Vision and the HGiG profile. We can conveniently manage all these features from a very readable gamer bar (Game Bar), which we can customise according to our own preferences. From a purely gaming perspective, the C8L really has no flaws – well, maybe apart from the previously mentioned slight ghosting. But other than that? It’s a no-nonsense machine for gamers.
