Philips OLED769 vs TCL C75B

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.

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

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.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

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 calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

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.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

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.

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

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.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.
