Philips OLED910 vs TCL C7L

The 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 dubbed its "META OLED." It is this panel that allows for over 2000 nits of brightness in films, which not long ago was completely unattainable in OLEDs. The television also deserves high praise for how it handles full-screen scenes drenched in bright light. Generally, in OLEDs, brightness drops significantly during such scenes, but here it remains at an excellent level – around 1400 nits. These are almost reference values, and combined with the 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.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness of around 2800 nits. This is an exceptionally phenomenal result, considering the price range it occupies. Unfortunately, tests of real film scenes are not quite as spectacular as measurements of white squares. Brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as this is the value to which the vast majority of contemporary films are mastered. However, when small, point-like elements appear on the screen, the brightness of these details drastically decreases – even down to around 400 nits – which diminishes the HDR effect somewhat. The television does this deliberately to maintain a better level of black and to avoid a giant light bloom. This is somewhat explainable, but it also shows that Mini LED technology is not entirely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colours are of course key here. And those, thanks to the use of new "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve about 90% coverage of the ultra-wide BT.2020 colour gamut and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such a high saturation of colours regardless of the scene being displayed, which often poses a challenge for competing RGB Mini-LED televisions.

After conducting a series of calibrations of the OLED910 model at our customers' locations, we noticed that the measurement results differ from those obtained during the initial tests. The factory tuning of the movie mode turns out to be significantly better than our first tests suggested. White balance is set very precisely, with only a minimal dominance of red. The factory colour reproduction stays 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 regarding the way the television manages brightness. Analysis of the Gamma (SDR) and EOTF (HDR) graphs shows a tendency to excessively 'pull' details out of the shadows. In practice, this means that the image may appear too bright, resulting in a loss of black depth in favour of visibility of details that should remain hidden. Of course, this effect can be effectively corrected during professional calibration.

Unfortunately, regarding colour reproduction right out of the box, the Filmmaker mode on the OLED910 performs really poorly. The television overemphasises the blue colour, and at times it looks almost like a shop mode. This gives the impression that the manufacturer did not quite tune the device properly. The effect is that colours appear unnatural, and the overall look is somewhat reminiscent of an overly exaggerated display in a store. HDR content performs much better, where aside from a slight loss of detail in the blacks, there's not much to complain about. The problem is that in everyday viewing, it is the SDR materials that matter most – and on the OLED910, they simply look poor and fall far short of what we would expect from a television of this class.

When it comes to colours straight out of the box, a new feature in TCL televisions – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was not available from this manufacturer before. By design, as indicated by the name itself, the image in this setting is meant to be presented with the full intention of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful colour reproduction straight out of the box. However, we certainly wouldn't say it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode tended to shift towards a slightly greenish-yellow hue, primarily caused by an excess of green and a clear deficiency of blue. Of course, for the average viewer, this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and unlocking the full potential of those new "super" quantum dots, then the television is crying out for professional calibration.

Fortunately, it quickly turned out that it was not the panel causing the problems, but rather the way Philips factory-calibrated the OLED910. After calibration, the television displayed its full potential, and only then could we see what the new panels produced by LG Display were truly capable of. We primarily adjusted the white balance and brightness characteristics, successfully taming the excessive blue and giving the image a natural appearance. 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 perfection and colours presented in accordance with the creators' intent. In SDR content, the effect was outstanding, 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 confidently be referred to as a reference in terms of colour quality.

After conducting a professional calibration, we were able to significantly improve the situation in the factory mode Filmmaker Mode. Following our adjustments, errors in the ColorChecker test and across the entire wide colour gamut fell below the threshold of human perception – that is, below a value of 3, which is truly an excellent result. The TCL C7L definitely benefits from such an operation in terms of colour fidelity, and this is difficult to dispute. However, the management of brightness in HDR content post-calibration does not look as good. As I described earlier – even though we set up this model appropriately, when we turn on real film scenes on the television, it manages its brightness in quite a peculiar way. It often highlights certain elements on the screen contrary to the creator's intention, which can be clearly seen in the EOTF graphs measured in specific films. Despite this defect – or rather the specific trait of this television – one cannot deny that after calibration, the C7L was able to reproduce colours completely accurately.

The previously visible colour banding can largely be mitigated thanks to a feature called "distortion reduction." Like in the OLED820, it is best set to a medium level, as it then produces fairly decent results – smoothing out unwanted tonal transitions while not taking away too much detail from the image. Although at times the effect may be slightly too aggressive, this function can be considered useful for everyday viewing.

As for image scaling, the OLED910 performs really well. The test material featuring a model had a soft look characteristic of Philips – at times almost too soft – but this can be easily corrected with the sharpness slider, allowing you to adjust the image to your own preferences. It's also worth noting that the television has no issues with overscan, which still occurs in some competitor models. It's a small detail, but it's pleasing because it means that all content, even the oldest, is displayed as it should be.

This point could be called, in a sense, the Achilles' heel of the C7L model. Unfortunately, this television uses an older chipset from MediaTek – the Pentonic 700 – which has never been known for outstanding digital picture processing. This is clearly visible in the performance of the smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – when set to a low level, its effectiveness is practically nonexistent. A small credit should perhaps be given here for the fact that the algorithm does not additionally ruin the picture or blur details forcibly. The upscaling, which is the scaling of the image from lower resolutions to 4K, fares a bit better. It is simply adequate and does not stand out in any particular way against the competition. However, it cannot be denied that the C7L would greatly benefit in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now found in an increasing number of competing models.

OLED910 is a television 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 panel used is capable of that. On the other hand, such a bonus would mainly benefit PC gamers, as in everyday use, the most important refresh rate is 120 Hz, which is fully sufficient. Combined with the advantages of the OLED panel – lightning-fast pixel response time and the absence of motion blur, the image is impeccably sharp and quick, even in dynamic action scenes. The traditional motion smoother from Philips, called “Motion Style,” also deserves praise. We can easily adjust it to our preferences: the “Fluidity” slider is responsible for films and allows you to choose between a more “filmy,” cinematic character and a smooth, theatrical image. Meanwhile, the “Motion Blur Reduction” slider is intended for sports, where it’s worth setting it to the maximum value to ensure that the image is clear and distinct during very fast shots.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which at lower resolutions – when using a PC – can even ramp up to 288 Hz. These are, of course, very high values and commendable on paper, but in everyday life, it is worth remembering that almost all dynamic content you display on this television will still rotate around a maximum of 120 Hz. To tame this dynamism, the television's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-tested guides on our YouTube channel. There, we have two key sliders at our disposal. The first one, "Motion Blur Reduction," is responsible for reducing blurring and improving sharpness in dynamic 60-frame materials, such as sports broadcasts. Meanwhile, the second slider, "Flicker Reduction," allows for the addition of artificial frames in films and series recorded at cinematic 24 or 30 frames per second. This certainly eliminates the irritating stutter in images during camera movement shots.

The OLED910 is fantastic for gaming. It supports 144 Hz, so if someone has a powerful PC, they can comfortably utilise that potential. On consoles, the most important thing is still 120 Hz, and everything works perfectly here. There's VRR, an automatic gaming mode, and even Dolby Vision in games and HGiG mode, so we really get a full package of gaming features. Philips has also added a Game Bar, which is a quick menu that displays basic information and allows you to enable a few useful things. It may not look as modern as the competition, but it works and fulfils its purpose. The only downside is the number of HDMI 2.1 ports. There are only two, which can be quite disappointing for a TV in this class. If someone connects two consoles and something additional through eARC - like a soundbar (which doesn't make much sense in this model but I'll discuss that in the paragraph about sound) - they'll have to do some adjustments. Other than that, the OLED910 has everything we expect from a gaming television.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, it provides access to all the key features that console and high-end PC owners require. It has a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates in an impressive range from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured a proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a very well-designed player panel, known as the Game Bar, which even allows you to customise its appearance and change the theme to perfectly match the style of your console.

The only thing that can – and indeed should – be critiqued here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home cinema system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you'll have to give something up or frequently juggle cables at the back of the unit while maintaining convenient control over your audio system.
