Philips OLED769 vs TCL C7L

Philips OLED769 performs quite well, particularly in film scenes with small points of light. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. As a result, fine sources of light, such as street lamps at night or stars in the sky, are sharp and full of detail. However, the biggest challenge for this model is the scene with a full-screen burst of sunlight. In such moments, the brightness drops to about 250 nits, which is not very impressive. This is a typical problem for cheaper OLED displays, which struggle to maintain high brightness across the entire screen surface.

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.

The "Film" mode proved to be the best factory setting in terms of fidelity to the source material, and it is on this that we based our tests. However, like other factory modes, it was not without flaws. Let us examine, therefore, what exactly went wrong in SDR and HDR materials.

In both cases, the white balance was disrupted by the excessive dominance of green and red hues. This phenomenon created a yellowish tint that spread across the entire image, leading to issues such as yellowed whites and unnatural skin tones. These problems were clearly highlighted on the "ColourChecker" palette, where each of the samples was shifted towards warmer tones.

As for contrast and brightness, in the Philips OLED769, we can look at two key graphs: Gamma for HD content and the EOTF curve for 4K HDR content. In the case of the first graph, the gamma value falls below the optimal level of 2.4, resulting in an increase in brightness of light areas of the image. This means that bright elements may be slightly overexposed, losing detail and depth. In contrast, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively conveys details in both the brightest and darkest areas of the image, resulting in a realistic and dynamic representation of scenes.

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.

After professional calibration, Philips OLED769 truly shines in terms of colour accuracy. The television has been completely stripped of any yellow tint in both HD and 4K content. The Colour Checker test confirms that deltaE errors are minimal, occasionally exceeding a value of 2, which means we can speak of almost perfect director's representation.

When it comes to contrast, the situation is equally impressive. With 4K materials, there wasn't much to improve initially, while the gamma chart has been significantly enhanced. This allows dark and light areas of the image to be represented with greater accuracy, resulting in a realistic and dynamic portrayal of scenes.

The calibration has allowed the full potential of this television to be unleashed, both in terms of colours and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they are watching films or using other multimedia.

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.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 handles tonal transitions well, especially at the minimum setting. It is worth noting that at this setting, film grain is not blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it is quite a decent solution. However, it should be pointed out that this setting does not work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the television struggles with smoothing tonal transitions and may present more noticeable distortions and noise, reducing picture quality in dynamic scenes.

Regarding digital processing, the Philips OLED769 performs well. The model in the photo is not overly jagged, and the branches in the background lack the characteristic jagged edges. The television achieves this effect thanks to the absence of artificial sharpness, which may be an advantage for some users. Others, however, may find this less attractive, as they prefer a more vibrant, sharper image instead of a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

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.

Philips OLED769 features a multi-stage motion smoother called "Motion Style", which will satisfy users who appreciate the ability to customise the fluidity of motion in films. With this function, you can set the image to be more frame-like or smooth, resembling a theatrical effect. This is a great solution for those who want to adapt the displayed content to their visual preferences. Gamers will also not be disappointed, as the television, like most OLEDs, is equipped with a 120Hz panel. This provides exceptional fluidity and dynamism of the image. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further improve motion fluidity and sharpness. Despite this limitation, the television still offers excellent visual experiences for both cinema lovers and gamers. This is definitely one of its strong points.

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.

Philips OLED769 has been designed with gamers in mind, offering full compatibility with consoles and the highest quality of gameplay. The television received the maximum rating in this category, providing everything that the heart desires. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the television ensures smooth and hassle-free gaming. ALLM automatically switches the television to low latency mode, while VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gaming. The Dolby Vision gaming feature is another advantage, although it only works at a frequency of 60 Hz. Most casual gamers will likely not feel the lack of a higher frequency; however, more demanding users may have some reservations. This allows for enjoyment of a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronises the refresh rate of the television with the graphics card, eliminating tearing and stuttering, resulting in excellent image fluidity.

Philips OLED769 is a television that perfectly meets the needs of gamers, offering a wide range of advanced features and technologies that significantly enhance gameplay quality and user comfort.

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.
