TCL P755 vs XIAOMI A PRO 2025

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 the HDR category, the Xiaomi A Pro performs poorly overall. Under ideal conditions, it achieves a brightness level of around 250 nits, which is underwhelming. However, many competing models offer similar or even lower brightness levels. Such limited brightness is insufficient to fully showcase the potential of HDR content. In practical terms, the image lacks the depth and intensity expected from high-quality HDR. Instead, the visuals resemble standard dynamic range (SDR), with scenes that should display striking brightness and contrast appearing flat and uninspiring. That said, for its price, the television offers solid DCI-P3 colour gamut coverage at 92%, made possible by its quantum dot (QLED) technology. This ensures vibrant and saturated colours, making it an appealing choice for gamers and movie enthusiasts seeking richer hues and improved colour reproduction compared to standard models.

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 Xiaomi A Pro 2025 performs best in movie mode for colour reproduction straight out of the box, though it is not without its flaws. An analysis of the white balance shows negative green values, causing distortions in white tones. At full white, there are noticeable deviations, and the high-contrast image leads to poor tonal transitions in red, negatively impacting the overall colour quality. Before calibration, the image often displays a pink hue in its scenery.

The gamma contrast graph falls below the 2.4 mark, indicating an overemphasis on darker tones and a lack of prominence in lighter areas. Additionally, the EOTF curve shows a sharp rise early on, which can result in lost detail in bright scenes and an oversaturated appearance. These issues suggest that further calibration is needed to balance the colour reproduction and enhance the overall image.

Factory colour settings on the Xiaomi A Pro 2025 are average, and while this is common in televisions of its class, users seeking accurate colour representation may need to adjust the settings. After proper calibration, the TV delivers a more natural and vibrant palette, aligning better with cinematic standards. For those prioritising precise colour reproduction, professional calibration will significantly improve image quality.

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 Xiaomi A Pro 2025 TV shows significant improvement. The white balance is the most noticeable change, with previous errors corrected in HD and 4K content. Most deviations are now minimal, falling within an acceptable range, resulting in a more balanced and natural colour representation that enhances viewing comfort.

In terms of gamma, the drop has been largely addressed, leading to a more consistent rendering of tones across various scenes. However, the EOTF curve still hasn't seen substantial improvement, as there is limited control over dynamic tone mapping. This limitation means that some details may still be lost in bright scenes, affecting the perception of certain materials.

Despite these minor issues, the overall picture quality is improved after calibration. The enhanced white balance and reduced gamma issues provide a more realistic and enjoyable viewing experience. While further adjustments could enhance the image even more, the TV now showcases its potential, meeting the expectations of many users.

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 Xiaomi A Pro 2025 handles tonal transitions effectively, especially when dealing with lower-quality materials. Thanks to its advanced digital processing, the colour contour removal feature performs surprisingly well. Setting this option to "Medium" provides the best balance, enhancing the smoothness of tonal transitions while avoiding excessive smoothing of other image elements, like film grain.

In the case of a tested frame featuring a model with numerous branches in the background, the TV demonstrated its digital processing strengths. Adding artificial sharpness clarified the model’s details, particularly enhancing the hair's definition. However, around the branches, subtle contours emerged due to digital intervention. While this adds detail to the overall image, excessive sharpness can sometimes cause certain elements to appear unnaturally highlighted.

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.

The Xiaomi A Pro 2025 features a motion smoothing option known as "Motion Smoothing," which is designed mainly for film viewing. It allows users to adjust the effect to either a more cinematic, film-like appearance with visible frames or a smoother, theatrical image. This feature will likely satisfy movie lovers. However, gamers and sports enthusiasts might be disappointed. The TV uses a 60 Hz refresh rate panel, typical for this price range, which doesn’t offer exceptional motion handling. Our "Ufo" test revealed some motion blur, so those seeking sharper moving images may find it lacking in this regard.

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.

The Xiaomi A Pro 2025 includes several gamer-friendly features, such as the Game Bar, which sets itself apart from the typical dashboards seen in other brands. This feature allows quick access to game-related settings, making it convenient during intense gaming sessions. The TV also supports Automatic Low Latency Mode (ALLM), automatically switching to a game-optimised mode to reduce signal delays. However, it lacks HDMI 2.1 support, limiting compatibility with the latest gaming consoles that require higher bandwidth. Additionally, it does not support features like VRR (Variable Refresh Rate) or G-Sync, which are becoming essential for gamers seeking smoother visuals and reduced tearing. While the Xiaomi A Pro 2025 has some useful features, there are better options in this price range offering more advanced gaming solutions.
