TCL P755 vs Hisense A7NQ

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.

We checked how the Hisense A7NQ performs with HDR, and there are no surprises here. The luminance chart showed a maximum brightness of 370 nits. The result? Exactly what one could expect – average. At a brightness of around 350 nits, HDR does not stand out particularly compared to SDR. Yes, a subtle difference can be seen in more brightly lit scenes, but it’s not a jaw-dropping effect. As for the coverage of the wide color gamut, the result was 92% for DCI-P3 and 70.2% for BT.2020. These are decent values for a TV in this class that uses an PFS coating – the same one that is sometimes promoted as QLED. Colors look good, but let’s not expect anything that competes with the best screens on the market. HDR on the Hisense A7NQ is more of an addition than a "game changer." For those looking for solid picture quality on a moderate budget – absolutely acceptable. However, if we expect full HDR capabilities, it is worth looking at higher-end 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.

When testing the Hisense A7NQ in Filmmaker mode, we hoped for compliance with the manufacturer's assumptions, but unfortunately, reality looks different. The main issue, as with most TVs, is the white balance. In the case of the A7NQ, we noticed a clear dominance of blue, which affected both lower quality materials and 4K HDR content. The Color Checker test results confirm this, and the comparison images speak for themselves – the main actress appears cool and pale in "factory" mode. It looks as if she has been stripped of life.

Regarding brightness characteristics, both gamma and the EOTF curve show that the image is excessively bright. As a result, everything seems flat, lacking depth and contrast. This state of affairs definitely does not work in favor of the A7NQ and makes the viewing experience in factory mode leave much to be desired. If we expect natural color reproduction and appropriate image depth, the A7NQ in Filmmaker mode is unlikely to impress us. It is a TV that requires significant adjustment to extract its potential.

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.

The Hisense A7NQ offers several tools that allow you to improve image quality, so we decided to take matters into our own hands and "dig around" in the settings a bit. Thanks to professional tools and measurements, we managed to correct the white balance, eliminating the excessive dominance of blue color in both HD and 4K materials. This is a significant step forward, as in the Color Checker test, color reproduction errors in lower quality content dropped to a much more acceptable level. Unfortunately, 4K materials are still far from ideal – color distortions are considerable and stem from the limitations of the television.

As for gamma, we managed to set it at the correct level, which significantly reduced excessive brightness of the image. However, the issue with brightness characteristics in 4K content remains unresolved – the EOTF curve still shows excessive illumination of the entire screen. It is possible that a proper implementation of dynamic tone mapping could help here, but as we mentioned earlier, this feature on the Hisense A7NQ works rather poorly instead of being helpful. Nevertheless, calibration significantly improved the overall image perception. The director's vision is now much better conveyed than in the factory settings, which more demanding viewers will certainly appreciate.

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 Hisense A7NQ impresses with smooth tonal transitions in 4K materials, but unfortunately, there is no feature here that would improve this aspect in older materials of lower quality. In such cases, color merging becomes more visible, which can somewhat spoil the viewing experience, especially in scenes with a lot of gradients.

When it comes to upscaling, the TV performs surprisingly well. The image is clearly improved, although it does come with some compromises. One can notice that the TV adds a bit of artificial sharpness, and elements in the background, such as branches, tend to exhibit slight "jagginess." These are details, however, that will mainly catch the eye of those who pay attention to such nuances.

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 Hisense A7NQ is equipped with a 60 Hz matrix, which means that dynamic scenes – for example, in sports or games – are somewhat average here. This is standard for this class of equipment, but it must be admitted that watching more intense, fast-moving content can leave a lot to be desired. However, when it comes to movies, the TV offers a motion smoothing feature that operates on a 10-level scale. The "motion blur reduction" option allows you to adjust the fluidity of the image to your own preferences. At the lowest setting, you get a natural film frame rate, which will please cinema purists. On the other hand, the maximum setting provides a very smooth, theatrical image that may appeal to those who prefer a more "smoothed out" motion.

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.

Hisense A7NQ is a device that can pleasantly surprise gamers, although it is not without its faults. The fact that we have a 60 Hz panel immediately suggests that the TV is not designed for the most demanding gaming scenarios. The motion blur we described earlier can also be a hindrance, especially in dynamic games.

However, there are several things worth praising. The TV supports ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), which are not always standard in this price range. The biggest surprise, however, is that the A7NQ can display images at 120 Hz – although only in Full HD resolution, it is still a significant nod to gamers. This allows a choice between smoothness and resolution, which is not obvious in TVs at this price point.

A nice addition is the Game Bar, which is clear and practical – all the main features are at hand without digging through the settings. However, there is a lack of support for HGiG, which may be disappointing for gamers looking for perfect HDR in games.
