TCL P755 vs Philips PUS7009 (VA)

The TCL P755 delivers an average HDR experience, with a maximum brightness of just under 300 nits. This limitation affects the intensity of bright areas in HDR content, reducing the contrast impact, as bright elements may appear less pronounced. However, the TV compensates with an impressive 93% coverage of the DCI-P3 colour gamut, which brings vibrant, saturated colours that enhance the quality of HDR content. Despite the brightness cap, the extensive colour range enriches hues, providing a more lifelike and visually engaging viewing experience.

In terms of HDR effect quality, Philips PUS7009 performs very poorly. A brightness level of 250 nits does not allow enjoyment of HDR effects, and the image resembles more of a standard SDR. There is no talk of dynamic effects or vivid light bursts. 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 to praise this model in the context of HDR.

In Cinema mode, the colour reproduction on the TCL P755, while set to the best factory configuration, falls short of ideal accuracy. The primary issue is the white balance, where the red component is notably elevated and the green is reduced. This imbalance shifts colours towards red, making them appear unnatural, particularly in scenes featuring white or neutral tones. This issue is highlighted in the Colour Checker test, which shows a discernible red bias affecting the realism of the image and diminishing the perception of colour depth.

Examining contrast performance, the gamma graph analysis reveals notable inconsistencies, especially in darker areas, where values dip below the target level of 2.4. Consequently, shadows and darker sections are displayed brighter than intended, impacting overall contrast. Furthermore, the EOTF (Electro-Optical Transfer Function) curve, essential for accurate brightness representation, veers slightly above the reference curve. The data shows a boost in brightness up to around 50% before a gradual levelling off. This creates excessive mid-tone brightness, which can lead to loss of detail and some distortion in brighter scenes, ultimately affecting the clarity and immersion of the viewing experience.

The TV 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 color, causing the image to appear cooler and colors to lose their natural warmth. The gamma brightness characteristics and EOTF curve confirm that the TV has trouble maintaining appropriate brightness – it boosts it significantly, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the overall appearance looks as if covered with a milky filter. 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.

Post-calibration, the TCL P755 delivers a markedly improved colour performance for SDR content. The colour curves now align closely with ideal values, with a more consistent gamma stability across the range. While a slight drop at the beginning of the gamma curve persists, the accuracy in colour reproduction is significantly enhanced. The Colour Checker test reveals most colour samples are now under an error threshold of 2, showcasing much-improved colour fidelity with only minimal deviations, resulting in colours that feel notably more authentic to life.

HDR content benefits from these calibration adjustments as well. White balance corrections lend a more natural tone, with colours appearing more balanced overall. The EOTF curve, while nearer to the ideal reference line, still features a mild brightness elevation at the start, which can cause minor distortions in exceptionally bright scenes. However, overall tonal quality and detail resolution have both improved. Tone mapping also performs more effectively, enhancing detail in bright regions while maintaining better image accuracy.

In summary, while calibration does not bring flawless performance, it makes a substantial difference in the P755’s visual quality. Following these adjustments, the television provides a more accurate, realistic viewing experience in both SDR and HDR content, smoothing out many of the previous colour inconsistencies for a more visually engaging result.

After calibration, the image has significantly improved, especially in terms of white balance, which is now more stable, and the shades have gained naturalness, eliminating the previous impression of an excessively cool image. The calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall picture appears 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 color 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.

The "Gradual Smoothing" function on the TCL P755 performs effectively, reducing visible boundaries between shades of the same colour and creating smoother tonal transitions. Unfortunately, this feature is unavailable in HDR mode, which can impact the quality of tonal gradations in high dynamic range content.

In terms of image scaling, the television shows some limitations. There are visible edge cut-offs, especially noticeable around figures and tree branches, which result in some detail blurring and a reduction in overall image sharpness. This is particularly noticeable when viewing lower-resolution content. Additionally, SD-quality images display a slight crop at the top and bottom, which may further impact viewing for standard-definition content.

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

In terms of image scaling, Philips PUS7009 performs decently. A major advantage is the absence 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 models or branches in the background, look quite detailed and natural, even with lower quality signals. Although the scaling is not perfect, as it can remove desired details in the distance, the results are good enough for most users to be satisfied.

The TCL P755 delivers satisfactory, though not flawless, motion smoothness. It includes a "Flicker Reduction" feature for films, allowing users to fine-tune motion smoothness on a scale from 1 to 10. This setting offers flexibility in tailoring the image to cinematic or more theatrical preferences, adjusting for a slower or faster appearance according to personal viewing taste.

Philips PUS7009 does not have motion smoothing features, which means there is no option to adjust the image for a more choppy or smoother, cinematic effect. Such features could positively influence the reception of dynamic scenes. As for motion blur, this model is equipped with a 60 Hz VA panel, which produces slightly worse results than the IPS panel variant. The VA panel introduces a minimally greater motion blur, although the differences are not significant and should not pose a problem for most viewers.

The TCL P755 comes equipped with gamer-oriented features like ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gaming, and a Game Bar. ALLM automatically activates low latency mode to enhance response times and reduce input lag, while VRR syncs the screen refresh rate with the console's frame output, minimising screen tearing for a smoother gaming experience. Dolby Vision for gamers brings improved colour and contrast for compatible games, and the Game Bar allows easy access to essential settings like response time.

However, the 60 Hz panel limits the display to this refresh rate across resolutions, which may impact the fluidity in high-motion games. The absence of G-Sync also affects PC gamers, as gameplay on computers lacks this technology's extra smoothing. Notably, HGiG mode, meant to optimise HDR game visuals, is not fully functional on this model, which slightly detracts from the HDR gaming experience.

In terms of compatibility with consoles, Philips PUS7009 is likely to satisfy casual gamers. Although equipped with HDMI 2.0, it offers features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the TV to low-latency mode, which speeds up reactions during gameplay, while VRR adjusts the refresh rate to minimize screen tearing. The Game Bar allows quick access to game settings and monitoring of key parameters, although it visually falls short compared to competing solutions. However, more demanding gamers may feel a sense of dissatisfaction. Philips PUS7009 does not support advanced HDR formats in games, and the 60 Hz panel limits the ability to display smooth and detailed images in dynamic scenes, which may not satisfy fans of fast-paced action games.
