TCL P755 vs Hisense E7NQ PRO

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.

Based on the luminance chart, which indicates around 550 nits, it can be considered that Hisense E7NQ PRO theoretically has the potential to somewhat "enchant" us with its HDR image. While testing various scenes, we noticed that the TV continually tries to balance maintaining adequate brightness and preserving the deepest blacks. In favourable conditions – for instance, during a scene from "The Meg," where the screen is flooded with bright light – this brightness impresses. At such moments, we feel that HDR actually adds that "something" to the image. Unfortunately, when more challenging shots appear on the screen with small, bright elements against a dark background, the situation looks much worse. The brightness then drops to 200-300 nits, too little to distinguish HDR from regular SDR.

It's clear that the TV is trying, but hardware limitations – primarily the small number of local dimming zones – prevent it from fully spreading its wings. The result can therefore be quite uneven and just as average as in the contrast tests. However, it deserves credit for the impressive coverage of the DCI-P3 colour gamut at 97%. This allows the TV to showcase a wide range of colours, which, in the right scenes, can give us at least a taste of the true HDR effect. It’s a pity that the overall experience isn’t complemented by better brightness and contrast.

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 we took our copy of Hisense E7NQ PRO out of the box, we immediately started checking the available picture modes. Among them, the Filmmaker mode seemed the most promising, although it was not without flaws. With standard SDR content, we noticed a clear tendency for an excessive boost in red, which caused the image to appear unnaturally warm. This is particularly evident in the comparison photo included below. On the other hand, when we switched to HDR content, the situation went in the opposite direction. This time blue was dominant, and red was scarce, giving a cool effect, at times even a somewhat "store-like" impression — although not as drastic as in those modes that are actually intended for displaying in exhibitions. As a result, in our colour reproduction tests, these imbalances in colour balance led to significant errors.

Additionally, the TV had issues with rendering brightness characteristics. At lower resolutions, it clearly brightened the darkest elements of the image, and with HDR content, the brightness curve (eotf) did not want to align as it should. Initially, the TV excessively darkened the smallest details and then overly brightened larger areas. Fortunately, the E7NQ PRO provides us with plenty of calibration tools, so knowing the potential, we decided to take matters into our own hands and try to set it up to eliminate these issues.

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.

Thanks to the tools available in E7NQ PRO, we managed to squeeze a quite decent image out of it, especially in the case of lower-quality content. After fine-tuning the white balance of the SDR materials, the colours look much more natural, and what we see on the screen seems closer to the vision the manufacturer intended to present. Additionally, we improved the brightness characteristic (Gamma), causing the TV to no longer have a tendency to over-brighten, and everything looks significantly better than before our intervention.

In HDR materials, we also managed to achieve some results, although it is not as rosy here. Indeed, the white balance has approached an acceptable level, but the problem lies elsewhere. It concerns the EOTF curve, which is how the TV manages the brightness and tonality of the image. At first glance, it might seem that the biggest issue pertains only to the mid-tones of the image, which are overly illuminated. However, after more detailed testing and enabling filters to display the EOTF curve, it is evident that the receiver tends to brighten the entire screen. This appears to be a limitation arising from the small number of local dimming zones and generally modest brightness management capabilities. Such hardware limitations are simply insurmountable. After our calibration, however, the image is noticeably better than at the start. One just needs to be aware that in terms of contrast and brightness management, this model has its limits, which even good calibration cannot fully overcome.

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.

Unfortunately, the "smooth and gradient image" feature in Hisense E7NQ PRO does not impress when it comes to smoothing tonal transitions in lower-quality materials. At the lowest setting, the change is hard to notice—it's more of a cosmetic improvement. Switching to "Medium" mode already provides a noticeable effect, but it still isn't anything special. In addition, the television starts to excessively interfere with other image elements, which can look unnatural.

Image scaling is also rather average. On the test screen, where a portrait of a model and text are displayed, slightly jagged edges can be seen, which makes the overall presentation less smooth and aesthetically pleasing than we would expect in this class of device. It's simply hard to speak of truly effective enhancement of lower resolution quality here.

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.

Thanks to its 144 Hz panel, the E7NQ PRO performs excellently with almost every type of content. Whether we are watching fast-paced matches, dynamic games, or action movies, the fluidity of motion leaves a good impression. For movies, the manufacturer has equipped the TV with two key tools: "motion blur reduction" and "judder reduction." Each of these functions can be adjusted on a scale from 1 to 10.

At lower values, the processing is subtle, barely noticeable, and gently smooths motion without ruining the cinematic character of the image. The higher we move up the scale, the more clearly the TV intervenes in the presented material, smoothing motion more forcefully, thus minimizing any stutter or micro-cuts. On the other hand, the highest settings may resemble the so-called "soap opera effect," which makes the image look overly smooth, losing some of its cinematic atmosphere. However, with such a scale, we can find the golden mean, adjusting the fluidity of motion to our own preferences.

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.

If you enjoy switching on your console and immersing yourself in games for hours, the E7NQ PRO is sure to make a strong impression. With its 144Hz refresh rate, gameplay feels impressively smooth, while support for HDMI 2.1 and VRR prevents screen tearing, even during the most action-packed moments. Additionally, ALLM automatically applies the lowest latency as soon as you switch to your console, so there’s no need to tweak the settings manually.

A major plus is the ability to play games in Dolby Vision, enhancing colours and contrast for a more vibrant experience. Hisense has also included a user-friendly game bar, allowing you to monitor key performance stats and adjust settings without leaving the game. The only real drawback is the absence of HGIG support. While not essential, some gamers may miss it if they’re looking for the most accurate representation of a game’s intended visuals. That said, in practice, the E7NQ PRO delivers an excellent gaming experience that’s smooth, responsive, and enjoyable.
