Philips OLED769 vs TCL P7K / P79K

Philips OLED769 performs quite well, especially in movie scenes with small light points. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. This means that small light sources, like street lamps at night or stars in the sky, are vivid and full of detail. However, the biggest challenge for this model is the scene with a full-screen sun glare. In such moments, the brightness drops to around 250 nits, which isn’t very impressive. This is a typical issue with cheaper OLED displays, which struggle to maintain high brightness across the entire screen.

When it comes to assessing HDR performance, we need to be clear and straightforward without any marketing fluff: the P7K/P79K is not and never was meant to be a champion in this area. The maximum peak brightness that this panel can generate hovers around just 300 nits. This represents a threshold, a sort of thin red line between what can be considered barely satisfactory HDR signal and what is, in reality, only slightly better than standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests confirmed this harsh reality – our measurements taken during movie sessions showed that the luminance in key bright scenes rarely exceeded 200-250 nits. Therefore, this is not a TV that would allow content created in a wide tonal range to truly shine, and that must be openly acknowledged.

Unfortunately, the issue of colour reproduction is presented just as conservatively. Although the manufacturer positions this model within the "QLED" family, owing to the use of a PFS LED filter, the results do not match the heightened expectations. The coverage of the wide DCI-P3 colour gamut reaches only 86%. Compared to the market, this is at best an average result, since most devices that utilise additional layers to expand the colour spectrum easily achieve values at a minimum of 90-92%.

The "Film" mode turned out to be the best factory setting in terms of fidelity to the original material, and it was on this setting that we based our tests. However, like other factory modes, it was not without its flaws. Let’s take a closer look at what exactly went wrong in the SDR and HDR materials.

In both cases, the white balance was disturbed by excessive dominance of green and red colours. This phenomenon created a yellowish tint that spilled over 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 shades.

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 is below the optimal level of 2.4, resulting in the bright parts of the image being lightened. This means that bright elements may be somewhat overexposed, losing detail and depth. Meanwhile, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively reproduces details in both the brightest and darkest parts of the image, translating to a realistic and dynamic representation of scenes.

Every reliable assessment of image quality must start with selecting the most optimal, factory preset mode. In the case of the tested P7K/P79K model, the choice was made without hesitation for the "Film" mode. It is the mode that presents an image closest to the intentions of its creators, avoiding both the exaggerated brightness of the dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it is not without a few stumbles. The most noticeable shortcoming turned out to be the not entirely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, frosty character, straying from the ideal neutrality that the director intended to show us. The television handles the reproduction of greyscale in the standard dynamic range much better – the gamma curve is almost exemplary. The only slight reservation can be made for the darkest parts of the image, where a delicate deviation from the norm causes a loss of some detail in the shadows. The most significant challenge, however, for the TCL software was interpreting the HDR signal, as illustrated by the EOTF curve. The television follows its own, rather free path here – the darkest details are disproportionately brightened, followed by a noticeable slowdown in brightness increase for mid-tones. Fortunately, most of these imperfections are of a software nature, which can be eliminated. With that thought in mind, we proceeded to the process of professional calibration.

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

When it comes to contrast, the situation is equally impressive. For 4K materials, there wasn't much to improve from the start, while the gamma graph has been significantly enhanced. As a result, dark and bright parts of the image are represented with greater accuracy, leading to realistic and dynamic scene reproduction.

The calibration has unlocked the full potential of this television, both in terms of colour and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they're watching movies or using other multimedia.

The calibration process turned out to be spot on, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the tendency of the television to showcase cool tones, restoring white to its natural neutrality. Moreover, the precise adjustment allowed us to correct a slight error in the gamma curve, enabling the darkest parts of the image to regain proper depth, without any signs of unnatural brightness. The results are measurable and impressive – in the ColorChecker test, the vast majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of below 2. This is a result that more expensive models would not be ashamed of. Unfortunately, in the case of HDR content, we encounter a wall in the form of the panel's structural limitations. And although we managed to bring the colours into line, the software's specifics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. To summarise, calibration adds tremendous value, but it is important to be aware that it won't overcome certain physical barriers. The slightly elevated blacks, resulting from the lack of local dimming, and limited peak brightness mean that HDR content won't always be able to showcase its full potential. This is simply not the main task of this display; its true strength, especially after professional tuning, lies in viewing SDR material.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 does well at smoothing tonal transitions, especially at the minimum setting. It's worth noting that at this setting, film grain isn't blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it's quite a decent solution. However, it should be noted that this setting doesn't 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 image quality in dynamic scenes.

As for digital processing, the Philips OLED769 performs well. The model in the picture isn’t overly jagged, and the branches in the background lack the characteristic artifacts. The television achieves this effect by avoiding artificial sharpening, which may be an advantage for some users. However, others may find this less appealing, as they prefer a more vivid, sharper image rather than a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

After a series of harsh evaluations, thankfully, it’s time for some praise, and this is deserved by the TCL AiPQ image processor for its work in the field of digital processing and content scaling. It should be noted right away that we are not talking about the level known from flagship models; nonetheless, in the price segment represented by the P7K/P79K, the results achieved are more than solid. The function that smooths tonal transitions performs particularly well, effectively eliminating posterization, which are the characteristic bands often visible in materials with higher compression, for instance, from choose.tv. The algorithm can elegantly remove unwanted gradients, which ultimately looks really good. The television also handles upscaling competently, which means the task of raising low-resolution materials to 4K standard. The resulting image, although it may seem a bit too sharp out of the box, is fortunately not a problem. The software allows for free adjustment of this parameter using a sharpness slider, allowing the final appearance to be easily tailored to personal preferences.

Philips OLED769 features a multi-level motion smoother called "Motion Style," which will please users who value the ability to adjust motion fluidity in films. With this function, the image can be set to appear more stuttery or fluid, reminiscent of a theatrical effect. It's a great solution for those who want to tailor 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 ensures extraordinary fluidity and dynamic imagery. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further enhance the smoothness and clarity of motion. 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 issue of fluidity and sharpness of motion image is inextricably linked to the fundamental parameter of the panel, and in the case of the TCL P7K/P79K, we are dealing with a panel that has a native refresh rate of 60 Hz. This specification at the outset defines its capabilities and makes it hard to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During quick camera movements, the image loses sharpness, and the panel also shows a slight tendency to smudge, which may be noticeable to more sensitive viewers. Fortunately, not everything in this aspect has been left to chance. The manufacturer has implemented a simple motion smoothing system, which is primarily used in film materials recorded at 24 or 30 frames per second. Thanks to a dedicated slider, the user can decide on the final nature of the motion – from maintaining a fully cinematic, slightly jerky image, to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows one to adjust the viewing experience to their own preferences.

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

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

Although on paper the native 4K@60Hz matrix might suggest that the TCL P7K/P79K is not a TV tailored for gamers, the reality turns out to be surprisingly different. On the contrary, the manufacturer has ensured a rich set of features that make it a very friendly companion for next-generation consoles. Onboard, we find key technologies such as ALLM, which provides automatic switching to low-latency mode, and VRR, or variable refresh rate, which eliminates screen tearing. The list is rounded off with support for Dolby Vision Gaming and a simple yet functional Game Bar. However, the real and extremely pleasant surprise is something else. It turns out that the TV effortlessly supports a high refresh rate signal of 120Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners, who know how rarely games run in native 4K at a full 120 frames per second. The option to choose between higher resolution and doubled smoothness is therefore an incredibly sensible compromise.

In summary, while the P7K/P79K may not be the target screen for the most passionate, tournament gamers, it offers a package of options for casual or occasional console users that is hard to find among many competitors at this price point.
