Philips PUS7009 (IPS) vs TCL P755

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

TCL P755 provides average HDR effect quality. The maximum brightness of the television is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, which affects the overall impression of contrast. However, the television offers a wide coverage of the DCI P3 colour gamut, reaching around 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

The television was tested in film mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television has issues maintaining appropriate brightness – it heavily boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the entire image appears as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not favour quality – colour checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

The colour reproduction in the P755 in "Movie" mode, although it is the best factory setting, leaves much to be desired. The biggest problem is the white balance, where the graph clearly shows a spike in red and a drop in green. This leads to a shift in colours towards red, making the colours on the screen less natural and potentially looking incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed skewed towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows considerable fluctuations, particularly in dark areas of the image, where values drop below the optimal level of 2.4. This results in darker areas being displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, is slightly above the reference curve. The graph shows a slight boost in brightness to around 50%, followed by only a minor decrease. This leads to excessive brightness enhancement in the mid-tones of the image and may result in loss of detail and distortion in brighter scenes.

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

After calibration, the colour reproduction on the television improves significantly when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the drop at the beginning of the graph to value is still present, the overall accuracy of colour reproduction is much better. The "Colour Checker" test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvement in HDR content. The white balance has been improved, resulting in a more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonal quality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and retaining more detail.

Although the device's picture does not achieve complete perfection, calibration brings significant improvement. After adjusting the settings, the television presents itself much better, offering a more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

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

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, appear quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desirable details in the distance, the results are good enough to satisfy most users.

The "Gradual Smoothing" function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which may affect the quality of tonal gradations in higher dynamic range materials.

When it comes to image scaling, the television does not perform at its best. There are noticeable edge cuts, particularly evident on the figure of the model and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Moreover, SD quality images are displayed with slight cropping at the top as well as the bottom.

Philips PUS7009 does not have any motion smoothing features for films, which means we cannot choose whether the picture should be more choppy 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 versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the comfort of watching dynamic scenes.

The television offers decent, although not perfect, results in terms of motion fluidity. For films, the television features a “Flicker Reduction” function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can customise the appearance of the image to a cinematic or more theatrical preference (with a slower or faster pace).

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

Unfortunately, more demanding gamers may be disappointed. The 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 television's ability to deliver smooth and fully detailed experiences during dynamic gameplay.

The device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, significantly improving response to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers enhances picture quality, offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as reaction time.

However, the television has certain limitations. The 60 Hz panel prevents the display of higher refresh rate signals at various resolutions, which may affect the smoothness of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact gameplay quality on a computer. It is also worth noting that the HGiG mode, which aims to improve picture quality in HDR games, does not function correctly in this model, negatively affecting the visual experience in HDR-supported games.
