Hisense U8NQ vs TCL C69K / Q6C

Hisense U8NQ demonstrates its capabilities in terms of HDR, achieving a luminance chart score exceeding 2000 nits. In the first, third, and fifth scenes where the screen is bathed in light, the television displayed very high brightness that impresses and allows one to fully enjoy the HDR effect. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2", the television encounters difficulties in maintaining brightness, resulting in disappointing scores around 250 nits. Although the large number of dimming zones should theoretically help, the algorithm responsible for their control does not always work perfectly — bright, small elements like the moon or helicopter lights are too dim, which detracts from the typical HDR effect. Instead of dazzling brightness, we get a more subdued light that does not realise the full potential of HDR. Nevertheless, the television deserves praise for its very good coverage of the DCI-P3 colour gamut at 97%. This results in vibrant colours, and most film scenes look really good, significantly enhancing the viewing quality.

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal film conditions, it shows its full potential, achieving a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a cinematic shimmer. However, it should be noted that when managing backlight zones, there are situations where parts of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimisation of the algorithms; however, considering the technical parameters in this price range, the design itself still presents very well.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode available on this model. Despite its accuracy, it has significant errors in reproducing reference images, which we will now describe. In the case of HD content, the white balance shows a clear dominance of red, making the image overly pink and warm. The comparative photo below illustrates how this effect impacts content presentation. The brightness characteristics also leave much to be desired — too low a gamma results in an excessively bright screen, and blacks appear elevated, making the overall image seem cooler than it should be.

In the case of 4K HDR content, the problem is the opposite — the white balance shows too great a dominance of blue, resulting in an artificial appearance and an unnaturally sharp image. All of these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly demonstrates how colours deviate from correct standards.

The Filmmaker mode, which has made its debut in this year's TCL televisions (including the C69K / Q6C), is definitely the best choice "to start with." This is the mode we recommend for daily film and series viewings. Unfortunately, as is often the case, best does not mean perfect. In SDR material, the image proved to be too warm, with a pronounced red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should, due to an excess of blue. Additionally, there is the characteristic of brightness, which at times resulted in overexposure. In practice, this translated into quite noticeable errors in colour tests, which is difficult to accept in a mode branded as "from the creators."

The white balance for both 4K and HD content has been significantly adjusted, which has greatly improved the picture quality. Although some errors are still visible, they are not large enough to heavily affect the perception of the image. A significant improvement can also be noticed in the gamma brightness characteristic — the picture is no longer excessively bright, translating into more natural blacks and better contrast.

However, as with many other Hisense models, there are visible issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although at first glance it may seem correct, when the filter is applied to the "EOTF in films" chart, it is evident that the television somewhat "manipulates" 4K content. It is clear that the EOTF curve is significantly below the reference level, leading to an overall dimming of the image compared to the reference. We noticed this effect in previously tested scenes from the films "Pan" and "Billy Lynn." While it is not a serious issue, it is worth noting. It may be of great importance to those seeking a display with the most faithful reproduction of the image. Despite this error, for most, the picture will be more enjoyable. Colours are better represented, and the overall picture quality is significantly improved.

Through white balance correction, we were able to significantly reduce the tendency of C69K / Q6C to distort colours, which yielded a very good final result. After calibration, the issue of excessive warming of scenes in SDR and excessive cooling of the image in HDR disappeared. However, it is worth analysing the brightness characteristics more closely. While in SDR content it is hard to have major objections – the image looks really good, especially in older films, TV programmes or on YouTube – it performs significantly worse in the case of HDR content. Analysis of the EOTF curve suggests that everything is fine, yet in practice (EOTF in films) the limitations of the design itself become apparent. This model has a tendency to excessively brighten small parts of the frame, only to overly dim the entire scene in other situations. The effect of calibration is therefore undeniable, and in terms of colour reproduction, C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

In the context of smoothing tonal transitions, the television Hisense U8NQ unfortunately struggles. The “Smooth and Gradient Picture” function does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially for demanding scenes with a lot of subtle tonal transitions.

Regarding digital processing, or so-called upscaling, the scene with the model is presented correctly — her outline is clear, without significant cropping. Similarly, thin lines, such as tree branches, exhibit slight jaggedness, but overall it looks plastic and soft, which creates a good impression. Unfortunately, there is also an issue with so-called overscan, which causes cropping of the image at the edges. This can be frustrating when watching content like news, where lower information bars may be partially invisible.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content appears acceptable, and thanks to the lack of overscan issues, the image is displayed in full without any cropping. However, one should not expect miracles – very low-quality materials will not gain a second life here, as the image processor has its limitations.

Thin lines and details exhibit characteristic tearing, which reveals the absence of more advanced image enhancement algorithms. It is also a pity that the C69K / Q6C lacks a tone transition smoothing feature. As a result, in older films or video materials, banding of colours can be visible and may become distracting during prolonged viewing.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The television will also easily satisfy film enthusiasts, as it features a built-in "Ultra Motion Smoothness" processor that allows you to control the smoothness of the image — you can decide whether you prefer a more "framey" picture or a smoother, theatrical effect. This provides great flexibility in adjusting motion quality to the viewer’s individual preferences.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. It represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz in 4K. The difference is particularly noticeable when watching sports or playing games – the ball, players, or dynamic action in games are displayed more clearly and without loss of detail. Another interesting feature is the panel's ability to work at 240 Hz (which the manufacturer does not officially mention) – we will return to this topic in relation to the PC gaming mode. TCL has also added a feature for movie fans: “Motion Clarity”. This allows users to adjust the picture to their preferences using two simple sliders. We can either keep the visible film frame or opt for very smooth, "

Hisense U8NQ offers everything a gamer may need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an extremely smooth image, particularly in dynamic action games. The VRR (Variable Refresh Rate) feature allows the image to adjust to varying frames per second, eliminating stuttering and tearing, resulting in exceptionally fluid gameplay. Additionally, the television is equipped with an ALLM (Automatic Low Latency Mode) feature, which automatically switches the television to gaming mode, minimising input lag. This allows players to enjoy responsive gameplay without the need to manually adjust settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high image quality, high contrast, and deep colours in games that support this format. The television also has a “Game Bar” — a feature that provides quick access to key settings during gameplay, significantly enhancing user convenience.

However, it is worth noting that despite its rich set of features, the Hisense U8NQ does not offer support for the HGiG standard, which is a popular HDR format in games. This may be disappointing for gamers expecting optimal detail reproduction in HDR scenes. Nevertheless, the other features of the television make the Hisense U8NQ a solid choice for console gaming enthusiasts, offering fluidity, high contrast, and user convenience.

TCL C69K / Q6C is a television that can confidently be described as equipment created 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 conveniently at hand – useful when we want to change something quickly during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is particularly noteworthy. However, this option is mainly for PC gamers who will operate below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. For consoles, we stick to the classic limit of 120 Hz, but even so, the capabilities are truly extensive. The only downside is a slight ghosting that can occasionally be seen in dynamic scenes. Other than that, C69K / Q6C offers everything that gamers expect from a television.
