Hisense E7NQ PRO vs TCL C6K

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.

TCL C6K is a moderately bright TV that can showcase its full potential under the best cinematic conditions – the maximum brightness is around 600 nits. In scenes with large, intense light sources, the HDR effect can be really satisfying, providing a sense of cinematic brilliance. However, it should be noted that when managing the backlighting zones, there are situations where some elements become dimmed and sometimes can even become barely visible. It is clear that there is a lack of proper algorithm optimization here, although looking at the technical parameters in this price range, the design itself performs very well.

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.

This year's TCL televisions feature a Filmmaker mode, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for everyday watching of movies and series. Unfortunately, as is often the case, the best doesn't mean perfect. In the case of SDR content, the image was too warm because the red was strongly emphasized in the white balance. On the other hand, with HDR content, we had the opposite impression – the image became cooler than it should have been due to excess blue. Additionally, the brightness characteristic sometimes led to highlights being blown out. In practice, this resulted in quite noticeable color test inaccuracies that are hard to accept in a mode advertised as "by the creators."

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.

Thanks to the white balance correction, it was possible to significantly reduce the C6K's tendency to distort colors, which resulted in a very good final outcome. After calibration, we will no longer observe the effect of excessive warming of scenes in SDR or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, there are few complaints – the image looks really good, especially in older movies, TV shows, or materials from YouTube. This is much worse for HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the construction become apparent. The TV tends to overly brighten the smallest parts of the frame, and in other situations, it can dim the entire scene too much. The effect of calibration is therefore evident, and in terms of color, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, its management by the C6K simply cannot be overcome.

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 C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the lack of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – content of very low quality will not gain new life here, as the image processor has its limitations. On thin lines or details, the characteristic tearing is visible, which reveals the absence of advanced image enhancement algorithms. It is also a pity that the C6K lacks the feature for smoothing tonal transitions – in older films or video materials, color banding can be noticeable and may be bothersome during long viewing sessions.

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.

TCL C6K features a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model C655 PRO, which offered only 60 Hz at 4K. The difference is especially noticeable when watching sports or playing games – the ball, athletes, or fast action in a game are displayed more clearly and without losing details. An interesting fact is also the ability of the panel to operate at 240 Hz, which the manufacturer does not mention in official materials. We will return to this topic when discussing the game mode for PC.

TCL also added a feature for movie watchers: "Motion Clarity," which allows you to adjust the image to your preferences using two simple sliders. You can keep the movie frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

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.

The TCL C6K is a TV that can confidently be called equipment designed for gamers. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there's a practical Game Bar, a panel with the most important settings readily available – useful when we want to quickly change something during gameplay (e.g., screen aspect ratio: Yes, that’s possible!). The wide VRR range, reaching up to 240 Hz, deserves attention. However, this is mainly an option for PC gamers who drop below the native 4K resolution. Then the TV can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is a slight ghosting that can sometimes be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a TV.
