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. 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.

TCL C6K is a moderately bright television that can showcase its full capabilities in the best movie 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's important to remember that with local dimming management, there are situations where some elements become dimmed, and sometimes even barely visible. It is clear that there is a lack of proper optimization of the algorithms, although looking at the technical parameters in this price range, the build quality 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 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.

This year's TCL televisions have introduced the Filmmaker mode, and it must be said that it is definitely the best choice right out of the box. This is the mode we recommend for everyday viewing of movies 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 prominent 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 an excess of blue. There is also the brightness characteristic, which at times led to overexposure. In practice, these issues combined resulted in quite noticeable errors in colour tests, which are hard to accept in a mode advertised as “by the creators”.

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.

Thanks to the white balance adjustment, we were able to significantly reduce the C6K's tendency to distort colours, which resulted in a very good end result. After calibration, we won't 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, it's hard to have major objections – the picture looks really good, especially in older movies, TV shows, or material from YouTube. It performs significantly worse with HDR content. An analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in movies), the limitations of the construction become apparent. The television tends to excessively brighten the smallest fragments of the frame, and in other situations, it can overly dim the entire scene. The effect of calibration is therefore noticeable, and regarding colourimetry, the C6K has really gained a lot, but certain limitations resulting from local dimming and actually from its management by the C6K simply cannot be overlooked.

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 C6K performs quite well in terms of upscaling. Lower quality materials appear acceptable, and the absence of overscan issues means the image is displayed in full, without cropping. However, one cannot expect miracles – very low quality content won't come to life here, as the image processor has its limitations. On thin lines or details, there is characteristic tearing visible, which indicates a lack of advanced image enhancement algorithms. It is also a shame that the C6K lacks the function of smoothing tonal transitions – in older films or video materials, colour banding can be noticeable and may be distracting during longer viewing sessions.

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 C6K uses a 144 Hz panel, which is a significant advantage in this price range. It's an important step forward in comparison to the previous model C655 PRO, which only offered 60 Hz in 4K. The difference is especially noticeable when watching sports or playing games – the ball, players, or fast action in the game are displayed more clearly and without losing detail. An interesting fact is the panel's ability to operate at 240 Hz, which the manufacturer doesn't mention in official materials. We will return to this topic when discussing the PC gaming mode.

TCL has also added a feature for movie watchers: "Motion Clarity," which allows users to adjust the image according to their preferences with two simple sliders. You can either keep the visible film frame or opt for a very smooth, almost theatrical effect. This way, everyone can find settings that match their taste.

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.

The TCL C6K is a television that can confidently be called equipment designed for gamers. We have 4K at 144 Hz, VRR support, an automatic gaming mode (ALLM), and Dolby Vision Gaming. On top of that, there's a practical Game Bar, which is a panel with the most important settings handy – useful when we want to quickly change something during gameplay (e.g. screen ratio: Yes, you can!). Notably, it has a wide range of VRR, reaching up to 240 Hz. However, this option is mainly for PC gamers who drop below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast e-sport titles. For consoles, we stick with the classic limit of 120 Hz, but the possibilities are still quite broad. The only slight drawback is some minor motion blur that can occasionally be seen in dynamic scenes. Other than that, the C6K offers everything gamers expect from a television.
