TCL P755 vs Philips PUS7000

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.

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is not enough to correctly display such a format. Even if a HDR signal message appears on the screen, the image will resemble a regular SDR recording. Therefore, it's better to stick with the latter format to avoid issues in displaying bright scenes, which you can read about below. The situation is not improved by the fact that this is a classic LCD model without additional layers to enhance colors, such as QLED or PFS. As a result, colors in HDR may appear washed out. Ultimately, this gives a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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.

We tested the television in movie mode, which theoretically should provide the best and most natural colors. And indeed, this mode is quite correct; however, after connecting the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant deficiencies in displaying red. Poorly tuned white balance and too low saturation of this color cause the image to appear too cool. As a result, one might get the impression that the displayed content is simply lacking in vibrant colors. The situation is exacerbated by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and may appear somewhat washed out. Fortunately, the Philips menu offers many functions to improve these aspects, so we immediately proceeded to calibration to see what could be squeezed out of this screen.

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 professional calibration, it is clear that the PUS7000 responds well to image adjustments. In this price range, this is not a given. The effects should be assessed in two scenarios, depending on what content we plan to watch. SDR performs the best. After our corrections, the image looks really good. Most color errors fell below level 3, which is the threshold at which distortions typically become visible to the naked eye in measurements. Movies, series, sports, and regular television present themselves naturally, without unpleasant deviations. If someone primarily watches classic channels or streaming in HD quality, the difference after calibration will be noticeable immediately. However, it must be made clear that the PUS7000 is still not a television suitable for sensible HDR, and calibration does not change much here. The reason lies in the hardware: colors remain too undersaturated. The television lacks solutions that expand the color gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot show the intense colors required by HDR. This is most evident in reds, which still look pale. This limitation cannot be bypassed with menu settings, as it results from the design of the backlighting and the panel itself.

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.

The PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths out unwanted tonal transitions even at a low setting. However, it has a flaw: if the action is too aggressive, it can introduce undesirable artifacts on the screen. It’s a good idea to experiment with this setting to find the sweet spot between a smooth image and detail clarity.

The upscaling, which is the enhancement of lower quality materials to 4K, is adequate. The image after processing is very "soft," which is typical for almost all Philips televisions. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu to achieve a more pronounced effect.

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.

In this regard, we don't really have any good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually standard, and it's hard to expect more. However, the worst part is that the TV does not have any motion smoothing features. There are no supporting systems for either movies or sports. We have to accept that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, the motion may appear choppy or unclear. We have no way to enable any smoother that would soften this effect.

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.

Although the PUS7000 is not marketed as a gaming TV, it does not perform as poorly in this category as one might expect. While there is no support for 120 Hz refresh rates, which is understandable at this price point, the manufacturer has included several important features that genuinely improve the comfort of playing on a console. The most significant of these are VRR and ALLM technologies. VRR is responsible for synchronizing the screen with the number of frames generated by the console. This prevents the image from "tearing" and keeps it consistent even during sudden frame drops in the game. In turn, ALLM is a solution that automatically switches the TV to the lowest latency mode right after detecting a signal from the console. All of these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick overview of current settings and connection status without interrupting gameplay, which is a very convenient solution.
