Philips PUS7009 (IPS) vs TCL P7K / P79K

In terms of HDR quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits does not allow for enjoyment of HDR effects, and the image resembles more of a standard SDR. There is no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 color palette is only 75%, which is definitely insufficient. The lack of full color coverage means that the colors are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects for which this model can be praised in the context of HDR.

When evaluating the HDR effect, we must make it clear and without marketing embellishment: the P7K/P79K is not and was never meant to be a master in this field. The maximum peak brightness that this panel can generate is only around 300 nits. This is a borderline value, a sort of thin red line between what can be considered a barely satisfactory HDR signal and what is really not much different from standard dynamic range (SDR), unfortunately leaning towards the latter. Synthetic tests found brutal confirmation in reality – our measurements taken during movie screenings showed that luminance in key bright parts of the content rarely exceeded the threshold of 200-250 nits. Therefore, this is not a television that would allow content produced in a wide tonal range to truly shine, and we must openly acknowledge that.

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

The television was tested in movie mode, which – despite its name – does not provide correct image display. The white balance in both 4K HDR and HD/SDR content is characterized by drops in red, causing the image to appear cooler and the colors to lose their natural warmth. The gamma brightness characteristic and EOTF curve confirm that the television has issues maintaining adequate brightness – it strongly boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the overall look appears as if a milky filter has been applied. Additionally, limited coverage of a wide color gamut also does not favor quality – color checker tests indicate significant color fluctuations, making it difficult to achieve faithful image reproduction.

Every reliable image quality assessment must begin by selecting the most optimal factory mode. In the case of the tested model P7K/P79K, the choice was confidently made for the "Film" mode. It is this mode that presents an image closest to the creators' intentions, avoiding both the exaggerated brightness of 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 free from a few stumbles. The most noticeable flaw turned out to be an imperfectly adjusted white balance. A slight dominance of the blue component gives the image a subtly cool, chilly character, thus deviating from the exemplary neutrality that the director wanted to show us. The television performs much better in reproducing the grayscale in a standard dynamic range – the gamma curve is executed almost perfectly. A minor reservation can only be made for the darkest parts of the image, where a slight deviation from the norm causes a loss of some detail in the shadows. The most serious challenge for TCL's software, however, was the interpretation of the HDR signal, which is 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 midtones. Fortunately, most of these imperfections are software-related issues that can be eliminated. With this thought in mind, we proceeded to the professional calibration process.

After calibration, the image has significantly improved, especially in terms of white balance, which is now more stable, and the hues have acquired a natural quality, eliminating the previous impression of being too cool. The calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall image appears more harmonious. Unfortunately, hardware limitations still affect image quality. The brightness characteristics remain problematic, despite our efforts, and due to poor coverage of the DCI-P3 and BT.2020 color palettes, delta E errors are still at a high level. Although calibration improved some aspects, the television still does not allow for complete satisfaction.

The calibration process turned out to be a home run, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the TV's tendency to emphasize cool tones, restoring the whites to their natural neutrality. Furthermore, precise adjustments allowed us to correct a slight error in the gamma curve, so the darkest areas of the image regained their proper depth, without a trace of unnatural brightening. The effects are measurable and impressive – in the ColorChecker test, the vast majority of color reproduction errors fell below the perceptual threshold, achieving a deltaE value below 2. This is a result that would not shame much more expensive constructions. Unfortunately, in the case of HDR content, we hit a wall in the form of the inherent limitations of the panel itself. And although we managed to bring the colors in line, the software's specifics mean that the TV still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. In summary, calibration brings tremendous added value, but one must be aware that it cannot overcome certain physical barriers. A slight boost in black levels, resulting from the lack of local dimming, and limited peak brightness mean that HDR content will not 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 the viewing of SDR materials.

When it comes to tonal transitions in low-quality material, the function called "Distortion Reduction" (setting "minimum") effectively improves grading, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur grain or high-quality material, it can introduce unwanted effects and blur elements that should remain sharp with a poorer signal.

In terms of image scaling, Philips PUS7009 performs decently. A significant advantage is the lack of cropped image edges, meaning no overscan, which allows for displaying the full frame without loss. The image is noticeably improved, making characters and backgrounds, such as the model or branches in the background, look quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desired details in the distance, the results are good enough for most users to be satisfied.

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

Philips PUS7009 does not have any motion smoothing feature for movies, which means we cannot choose whether the picture should be more stuttery or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in VA panel versions, which means that motion blur remains at an acceptable level and does not significantly affect the viewing comfort of dynamic scenes.

The issue of fluidity and sharpness of the image in motion 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 already defines its capabilities and makes it difficult to unequivocally recommend it to enthusiasts of dynamic sports broadcasts. During rapid camera movements, the image loses sharpness, and the panel itself also shows a slight tendency to blur, 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 independently decide on the final character of the motion – from a fully cinematic, slightly juddery image to achieving a very smooth, almost theatrical effect. It is a simple yet effective tool that allows users to tailor the viewing experience to their own preferences.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite using HDMI 2.0, the TV offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low latency mode, allowing for faster response during gameplay, while VRR dynamically adjusts the refresh rate to reduce screen tearing. Game Bar is a tool that provides quick access to game settings and real-time monitoring of parameters - though we believe it appears weaker compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the TV's ability to deliver smooth and fully detailed experiences during fast-paced gameplay.

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 package 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 completed by 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 easily supports high refresh rate signals of 120 Hz, but at lower resolutions – 1080p and 1440p. This is fantastic news for console owners who know full well how rarely games run in native 4K at a full 120 frames per second. The ability to choose between higher resolution and doubled smoothness is therefore an extremely sensible compromise.

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