Hisense E7NQ PRO vs TCL C75B

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.

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

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.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

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.

After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

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.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

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 TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

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.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.
