Hisense E7NQ PRO vs TCL C75B

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. Testing various scenes from movies, we noticed that the television continually tries to balance between maintaining appropriate brightness and preserving the deepest blacks. In favourable conditions – such as in a scene from “The Meg”, where the screen is flooded with bright light – this brightness can indeed impress us. At such moments, we feel that HDR actually adds that "something" to the image. Unfortunately, when difficult shots with fine, bright elements on a dark background appear on the screen, the situation looks much worse. Brightness then drops to 200-300 nits, which is definitely too little to really distinguish HDR from standard SDR.

It is clear that the television is trying, but the hardware limitations – mainly the small number of local dimming zones – prevent it from fully spreading its wings. The end result can therefore be quite inconsistent and as average as the contrast tests. On the plus side, it deserves credit for its impressive coverage of the DCI-P3 colour gamut at 97%. This allows the television to present a truly wide range of colours, which, in the right scenes, can give us at least a glimpse of the real HDR effect. It’s just a shame that the whole picture isn't complemented by better control of brightness and contrast.

During our brightness test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. These can be considered average – the TV performs decently in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, such results are better than those of budget models, which can achieve nearly half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the plus side, it's worth mentioning the coverage of the DCI-P3 colour gamut at 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 started checking the available picture modes. Among them, the Filmmaker mode seemed the most promising, although it wasn't without its flaws. With standard SDR content, we noticed a clear tendency to overemphasise red, making the picture appear unnaturally warm. This was particularly evident in the comparison photo attached below. Conversely, when we switched to HDR content, the situation took a turn in the opposite direction. This time, blue was dominant, and there was hardly any red, resulting in a cool, at times almost "store-like" appearance — although not as drastic as in modes specifically designed for showcasing in displays. As a result, in our tests assessing colour reproduction, these disturbances in colour balance led to significant errors.

Additionally, the television had trouble reproducing brightness characteristics. At lower resolutions, it clearly brightened the darkest elements of the image, and with HDR content, the brightness curve (eotf) simply wouldn't align as it should. Initially, the television excessively darkened the smallest details, only to then over-brighten larger areas. Fortunately, the E7NQ PRO provides us with a lot of calibration tools, so knowing there was potential within it, we decided to take matters into our own hands and try to set it up to eliminate these issues.

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

An additional problem was the way brightness was reproduced. 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 black (e.g., the bottom part of the screen in the comparison image - the area around the actress's ear). The situation was similar on the EOTF curve, which was below the correct value, suggesting that a similar issue may be encountered in 4K HDR content.

Thanks to our experience and the appropriate tools, we decided to take matters into our own hands and check how much could be extracted from this model after professional calibration. The details are described in the next section.

Thanks to the tools available in E7NQ PRO, we've managed to squeeze a pretty decent image out of it, especially with 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 producer intended to present. Additionally, we've improved the brightness characteristics (Gamma), so the TV no longer tends to over-brighten, and everything looks noticeably better than before our intervention.

With HDR materials, we also achieved some improvements, although it's not as rosy here. Yes, the white balance has approached an acceptable level, but the problem lies elsewhere. It's about the EOTF curve, which is how the TV manages brightness and tonality of the image. At first glance, one might think that the biggest issue concerns only the mid-tones, which are overly brightened. However, after more detailed testing and activating the EOTF curve visualisation filters, it becomes clear that the receiver has a tendency to brighten the entire screen. This seems to be a limitation due to the small number of local dimming zones and generally modest brightness management capabilities. Such hardware limitations are simply insurmountable. Nonetheless, after our calibration, 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 a good calibration cannot fully overcome.

After calibration, TCL C75B has clearly improved when it comes to colour reproduction. Although the TV doesn't offer too many options for adjusting the white balance, we managed to improve its settings quite a bit. As a result, the image is no longer overly pink, and the colours now look much more natural and harmonious.

The gamma jump that was previously an issue hasn't completely disappeared, but we were able to significantly reduce it. This has made details in dark scenes more visible – both in HD and 4K HDR content.

Unfortunately, the lack of local dimming is still noticeable. The 'blooming black' effect remains, but that's a limitation of the display itself. Still, the colours post-calibration look significantly better, and the image is much more pleasant to watch.

When it comes to the tonal transition smoothing function 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 barely noticeable – it's more of a cosmetic improvement. Switching to “Medium” mode does produce a noticeable effect, but it's still nothing special, and the TV starts to excessively interfere with other elements of the image, which can look unnatural.

Image scaling is also rather average. On the test screen, where a portrait of a model and text are displayed, there are slight frays at the edges, making the overall presentation less smooth and aesthetic than we would expect in this class of device. It's just hard to talk about really effective improvement of lower resolution quality here.

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

Image scaling is better. The TV handles it quite decently, although on thinner elements, like branches in the background, you can see slight jaggedness. However, this is not something that significantly hinders everyday viewing.

Unfortunately, a bigger problem turned out to be overscan, or cropping of the image edges. In our tests, it happened that news ticker or other elements close to the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the TV for watching news programs or content with text on the screen.

Thanks to the use of a 144 Hz panel, E7NQ PRO performs exceptionally well with almost any type of content. Whether we're watching fast-paced matches, dynamic games or action films – the fluidity of motion leaves a good impression. When it comes to 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 interferes with the presented material, smoothing motion more aggressively, thereby minimising any judders or micro-cuts. Conversely, the highest settings can resemble the so-called “soap opera effect,” which makes the image look overly smooth, slightly losing its cinematic atmosphere. Thanks to this scale, however, we can find a happy medium, adjusting motion fluidity to our own preferences.

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 budget range.

On top of that, there are features for improving smoothness and reducing motion blur in films. The "Motion" option allows for precise adjustment of the effect on a 10-point scale, providing significant personalisation possibilities – everyone can set the smoothness to their liking.

If we sometimes like to turn on the console and immerse ourselves in the world of games for long hours, E7NQ PRO can make a really good impression. Thanks to the 144 Hz refresh rate, the gameplay is surprisingly smooth, and support for HDMI 2.1 and VRR ensures that the image 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 around in the options ourselves.

A big plus is also the ability to launch games in Dolby Vision, which makes colors and contrast simply look better. Hisense has also included a clear "gamebar," allowing us to continuously monitor the key parameters and change settings without leaving the game. The only thing we might slightly regret is the lack of HGIG support. It may not be a crucial element, but for some gamers, it can matter if they aim for the most faithful reproduction of the creators' vision. Nevertheless, in practice, the E7NQ PRO performs excellently and delivers truly enjoyable gaming experiences.

TCL C75B is undoubtedly a television designed with gamers in mind. It has almost everything needed for even the most demanding console users. With the implementation of full bandwidth HDMI 2.1, the TV supports features like ALLM (automatic low latency mode) and VRR (variable refresh rate) – operating within the full capabilities of the TV, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, which allows for even better detailing in HDR-optimised games. C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where you can check all key parameters such as refresh rate, input lag, or picture settings – all just a click away.

In one sentence: C75B is a great choice for gamers, offering a wide range of features that fully enable enjoyment of the capabilities of modern consoles and games.
