Philips PUS7009 (IPS) vs Philips PUS8079

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.

The Philips PUS8079 has a maximum brightness of just 202 nits in content with a wide tonal range, which is very low and makes it unsuitable for streaming movies and series in the highest quality. Additionally, using HDR with dynamic metadata doesn’t improve the situation, as the only HDR format available on this model is HDR10+, which is rare and has limited content support. The TV also uses WLED backlighting, which is not optimal and results in only 80% coverage of the DCI-P3 wide colour gamut. This limits the intensity of colours in HDR content.

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.

The best factory mode for colour reproduction and fidelity to the director's vision on the Philips PUS8079 was the "Film" mode. However, this setting displayed significant discrepancies between the filmmaker's intent and the actual output. In both SDR and HDR materials (with HDR being less affected), the white balance was off, showing a blue tint similar to store displays, rather than pure whites. When it came to SDR materials, gamma was notably lowered, cutting into the already limited contrast and brightening the overall image. The EOTF curve in HDR content also showed a significant drop below the reference line, making HDR materials appear even darker. The colour accuracy in both SDR and HDR modes was poor, with high deltaE values indicating that the colours were far from their intended representation.

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.

Fortunately, Philips incorporates advanced image correction tools across its televisions. SDR content benefited the most from these adjustments, with significant improvements in deltaE errors, white balance, and gamma. While the image still isn’t perfect, it is much more watchable, making it easier on the eyes during movie or series viewing. HDR content, however, was more challenging due to the television’s low luminance. While the EOTF curve and white balance improved, the corrections weren’t as effective as with SDR materials. It’s important to note that each unit may have different errors, some larger and some smaller, but the adjustments made were a step in the right direction.

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.

Let us revisit the topic of tonal transitions, this time in the context of overall image quality enhancement. As shown in the photo on the left, the gradation improvement feature delivers excellent results. It provides multiple settings, each offering noticeable benefits without softening the film grain effect. Once again, it must be emphasised that this feature is the standout advantage of the tested television.

On the other hand, the television’s performance in image scaling leaves much to be desired. Fine details often appear heavily jagged, with a noticeable white halo around figures. Additionally, the significant artificial sharpening detracts from the overall image quality.

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.

This paragraph will be notably brief due to the absence of even basic motion-smoothing functionality, which is unsurprising given the device's budget-oriented nature. The VA panel used here is not known for exceptional sharpness and is instead associated with high contrast and slower response times, as confirmed by the matrix analysis results. Photos captured during fast motion reveal typical motion blur for this type of panel. While not ideal, the television could be conditionally suitable for watching sports, though viewers should expect less-than-optimal motion clarity. Additionally, films may exhibit noticeable stuttering due to the lack of any motion-smoothing features, even basic ones.

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.

The Philips PUS8079 provides only basic gaming features, including ALLM, VRR, and a Game Bar. The key highlight is the inclusion of dynamic frequency adjustment, which ensures a smooth image with minimal screen tearing—an impressive offering for this price range.

A notable benefit for gamers is the presence of the Game Bar, allowing adjustments to be made "on the fly" without needing to exit the game. Importantly, this feature retains options found in higher-end models, such as shadow enhancement for improved visibility in darker areas and a colour filter designed to assist gamers with visual impairments.
