Hisense E7NQ PRO vs TCL C6K

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.

TCL C6K is a moderately bright television 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 truly satisfying, providing a sense of cinematic sparkle. However, it is important to remember that when managing backlight zones, there are occasions where some elements are dimmed, and at times become barely visible. It is clear that there is a lack of proper algorithm optimisation here, although looking at the technical parameters in this price range, the overall construction performs exceedingly well.

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.

In this year's TCL televisions, the Filmmaker mode has appeared, and it must be admitted that it is definitely the best choice straight out of the box. This is the mode we recommend for daily watching of films and series. Unfortunately, as is often the case, the best does not mean perfect. In the case of SDR content, the image was too warm, as the red was quite pronounced in the white balance. Conversely, with HDR content, we had the opposite impression – the image became cooler than it should have been due to an excess of blue. Additionally, the brightness characteristics sometimes led to overexposure. In practice, this resulted in quite noticeable errors in colour tests, which are difficult to accept in a mode advertised as "from the creators."

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.

Thanks to the white balance adjustment, it was possible to significantly reduce the C6K's tendency to distort colours, which translated into a very good final result. After calibration, we will no longer observe the effect of excessive warmth in SDR scenes or overly cooling the image in HDR. However, it is worth taking a closer look at the brightness characteristics. In SDR content, it is difficult to have major objections – the image looks really good, especially in older films, television programmes, or materials from YouTube. It fares much worse in the case of HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the design become apparent. The television tends to over-brighten the smallest parts of the frame, and in other situations, it can dim an entire scene too much. The effect of calibration is therefore evident, and in terms of colour, the C6K has gained quite a lot, but certain limitations arising from local dimming and, in fact, from its management by the C6K simply cannot be overcome.

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 C6K performs quite well in terms of scaling. Lower quality materials look acceptable, and the absence of overscan issues means that the image is displayed in full, without cropping. However, one cannot expect miracles – very low-quality content will not gain a new life here, as the image processor has its limitations. On thin lines or details, there is a noticeable characteristic jerking, which reveals the lack 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, colour banding can be noticeable and can be distracting during longer viewing sessions.

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 C6K utilises a 144 Hz panel, which is a significant advantage in this price range. This is an important step forward compared to the previous model, the C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or gaming – the ball, players, or fast action in a game are shown more clearly and without losing details. Interestingly, the panel can also operate at 240 Hz, which the manufacturer does not mention in the official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for those watching films: "Motion Clarity", which allows users to adjust the image to their liking using two simple sliders. One can either keep the film frame visible or opt for a very smooth, almost theatrical effect. This way, everyone can find settings tailored to their taste.

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 C6K is a television that can confidently be described as equipment designed with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there is a practical Game Bar, which is a panel with the most important settings easily accessible – useful when we want to quickly change something during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR is also noteworthy, reaching up to 240 Hz. However, this option is primarily for PC gamers who will drop the resolution below native 4K. At that point, the television can spread its wings and demonstrate extra fluidity, especially in fast-paced esports titles. In the case of consoles, we stick to the classic limit of 120 Hz, but the possibilities are still really broad. The only drawback might be slight ghosting, which can sometimes be seen in dynamic scenes. Apart from that, though, the C6K offers everything that gamers expect from a television.
