TCL P755 vs Hisense E7NQ PRO

TCL P755 provides average HDR effect quality. The maximum brightness of the television is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, which affects the overall impression of contrast. However, the television offers a wide coverage of the DCI P3 colour gamut, reaching around 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

Based on the luminance chart, which indicates around 550 nits, it can be said that Hisense E7NQ PRO theoretically has the potential to somewhat "magically" enchant us with its image in HDR. While testing various scenes from films, we noticed that the television continually tries to balance maintaining appropriate brightness with preserving the deepest blacks possible. In favourable conditions – for instance, during a scene from “The Meg,” where the screen is flooded with bright light – this brightness can indeed impress us. In 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 on a dark background, the situation looks significantly worse. The brightness then drops to 200-300 nits, which is decidedly too little to truly distinguish HDR from standard SDR.

It is clear that the television tries, but hardware limitations – mainly the limited number of local dimming zones – prevent it from fully spreading its wings. The final effect is therefore often quite uneven and just as mediocre as in the contrast tests. However, it deserves credit for its impressive coverage of the DCI-P3 colour gamut at 97%. Thanks to this, the television can display a truly wide range of colours, which, in suitable scenes, can give us at least a taste of the true HDR effect. It’s just a shame that the overall experience is not complemented by better control of brightness and contrast.

The colour reproduction in the P755 in "Movie" mode, although it is the best factory setting, leaves much to be desired. The biggest problem is the white balance, where the graph clearly shows a spike in red and a drop in green. This leads to a shift in colours towards red, making the colours on the screen less natural and potentially looking incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed skewed towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows considerable fluctuations, particularly in dark areas of the image, where values drop below the optimal level of 2.4. This results in darker areas being displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, is slightly above the reference curve. The graph shows a slight boost in brightness to around 50%, followed by only a minor decrease. This leads to excessive brightness enhancement in the mid-tones of the image and may result in loss of detail and distortion in brighter scenes.

When we took our copy of Hisense E7NQ PRO out of the box, we immediately began to check the available picture modes. Among them, the Filmmaker mode seemed the most promising, although it too was not without its flaws. With standard SDR content, we noticed a clear tendency for excessive red enhancement, which made the image unnaturally warm. This was particularly evident in the comparative photo attached below. Conversely, when we switched to HDR content, the situation went in the opposite direction. This time, blue was dominant, and red was scarce, resulting in a cool effect, at times almost "shop-like" — although not as drastic as in those modes that are actually intended for display in exhibitions. As a result, in our tests assessing colour reproduction, these disturbances in colour balance led to significant errors.

Additionally, the television had issues with reproducing brightness characteristics. At lower resolutions, it noticeably brightened the darkest elements of the image, and with HDR content, the brightness curve (eotf) simply wouldn't conform as it should. Initially, the television excessively darkened the smallest details, only to then overly brighten larger areas. Fortunately, the E7NQ PRO provides us with plenty of calibration tools, so knowing that there is potential within it, we decided to take matters into our own hands and try to adjust it to eliminate these problems.

After calibration, the colour reproduction on the television improves significantly when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the drop at the beginning of the graph to value is still present, the overall accuracy of colour reproduction is much better. The "Colour Checker" test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvement in HDR content. The white balance has been improved, resulting in a more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonal quality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and retaining more detail.

Although the device's picture does not achieve complete perfection, calibration brings significant improvement. After adjusting the settings, the television presents itself much better, offering a more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

Thanks to the tools available in E7NQ PRO, we managed to extract quite a decent image from it, especially with lower quality content. After refining 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 that the manufacturer intended to present. Additionally, we improved the brightness characteristic (Gamma), which means the television is no longer prone to excessive brightening, and everything presents itself distinctly better than before our intervention.

We also managed to achieve some results with HDR materials, although it isn’t quite as rosy here. Indeed, the white balance has approached an acceptable level, but the problem lies elsewhere. It concerns the EOTF curve, which is the way the television manages brightness and tonal range of the image. At first glance, it might seem that the biggest issue only relates to mid-tones being overly brightened. However, after more detailed testing and enabling the filters for displaying the EOTF curve, it becomes apparent 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. Despite this, after our calibration, the image is noticeably better than at the outset. 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 works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which may affect the quality of tonal gradations in higher dynamic range materials.

When it comes to image scaling, the television does not perform at its best. There are noticeable edge cuts, particularly evident on the figure of the model and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Moreover, SD quality images are displayed with slight cropping at the top as well as the bottom.

When it comes to the function of smoothing tonal transitions in lower quality materials, the "smooth and gradient image" feature in Hisense E7NQ PRO unfortunately does not impress. At the lowest setting, the change is hard to notice at all – it is rather a cosmetic improvement. Switching to "Medium" mode yields a noticeable effect, but it is still nothing special, and in the process, the television begins to excessively interfere with other elements of the image, which can look unnatural.

Moreover, image scaling is rather average. On the test screen, where a portrait of a model and text are displayed, slight jagged edges are visible, making the overall appearance less smooth and aesthetically pleasing than one would expect in this class of device. It's simply difficult to talk about truly effective improvement in the quality of lower resolution.

The television offers decent, although not perfect, results in terms of motion fluidity. For films, the television features a “Flicker Reduction” function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can customise the appearance of the image to a cinematic or more theatrical preference (with a slower or faster pace).

Thanks to the use of a 144 Hz panel, E7NQ PRO performs excellently with nearly every type of content. Whether we are watching fast-paced matches, dynamic games or action films – the smoothness of motion leaves a good impression. When it comes to films, the manufacturer has equipped the television 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 out motion without compromising the cinematic quality of the image. The higher we move up the scale, the more the television interferes with the presented material, smoothing out motion more intensely, and consequently – minimising any judders or micro-cuts. Conversely, the highest settings can resemble the so-called "soap opera effect", which makes the image appear excessively smooth, slightly losing its filmic atmosphere. However, with such a scale, we can find a happy medium, adjusting the smoothness of motion to our own preferences.

The device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, significantly improving response to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers enhances picture quality, offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as reaction time.

However, the television has certain limitations. The 60 Hz panel prevents the display of higher refresh rate signals at various resolutions, which may affect the smoothness of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact gameplay quality on a computer. It is also worth noting that the HGiG mode, which aims to improve picture quality in HDR games, does not function correctly in this model, negatively affecting the visual experience in HDR-supported games.

If we sometimes enjoy turning on the console and immersing ourselves in the world of games for long hours, E7NQ PRO can make quite an impressive impact. Thanks to the 144 Hz refresh rate, gameplay is surprisingly smooth, and support for HDMI 2.1 and VRR ensures that the picture doesn't 'tear' even during the most dynamic actions. Additionally, there's ALLM, which automatically sets the lowest latency as soon as we switch to the console – so we don't have to fiddle with the options ourselves.

A major plus is also the ability to run games in Dolby Vision, making colours and contrast simply look better. Hisense has also added a clear 'gamebar', allowing us to constantly monitor the most important parameters and change settings without leaving the game. The only thing we might regret a bit is the lack of HGIG support. While it may not be a crucial element, it could matter to some gamers aiming for the most faithful representation of the creators' vision. Nevertheless, in practice, the E7NQ PRO performs excellently and provides truly enjoyable gaming experiences.
