Hisense U8NQ vs TCL C69K / Q6C

Hisense U8NQ demonstrates its capabilities in HDR, achieving a luminance score on the chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television showcased very high brightness, which is impressive and allows you to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2," the television encounters issues 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 dimmed, which takes away from the typical HDR effect. Instead of blinding brilliance, we receive a more subdued light that does not convey the full potential of HDR. Nevertheless, the television deserves commendation for its very good coverage of the DCI-P3 colour gamut at 97%. This makes colours vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal movie conditions, it shows its full potential, reaching a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, giving a cinematic glow. However, it's important to keep in mind that when managing the backlight zones, there are situations where parts of the image are dimmed, and at times become barely visible. This suggests that there is still a lack of proper optimization of the algorithms, although considering the technical parameters in this price range, the overall construction still looks very good.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode present in this model. Despite its accuracy, it has significant errors in reproducing the reference image, which we will describe now. In the case of HD content, the white balance shows a distinct dominance of red, causing the image to appear overly pinkish and warm. In the comparison photo below, you can see how this effect impacts the presentation of content. The brightness characteristic also leaves much to be desired—a too low gamma causes the screen to be excessively brightened, and blacks appear washed out, making the overall image seem cooler than it should be.

For 4K HDR content, the problem is the opposite—the white balance shows too much dominance of blue, making the image take on an artificial quality and seem unnaturally sharp. All these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly shows how the colours deviate from the correct patterns.

The Filmmaker Mode, which has been introduced in this year's TCL TVs (including the C69K / Q6C), is definitely the best choice "to start with". This is the mode we recommend for everyday movie and series viewing. Unfortunately, as is often the case, best does not mean perfect. In SDR materials, the image turned out to be too warm, with a strong red tint in the white balance. The opposite impression was had with HDR content – here the image became cooler than it should have been, due to an excess of blue. Additionally, there is the brightness characteristic, which at times resulted in overexposures. In practice, this translated to fairly noticeable errors in color tests, which is difficult to accept in a mode branded as "by the creators".

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

However, like with many other Hisense models, there are noticeable issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although it may seem correct at first glance, when the filter is applied to the "EOTF in films" chart, it is evident that the TV is somewhat "playing around" with 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 paying attention to. It could be significant for those seeking a display with the most faithful image reproduction. Despite this error, the image will be more enjoyable for most. Colours are represented better, and the overall image quality is significantly improved.

Through white balance adjustment, we were able to significantly reduce the tendency of ChooseTV C69K / Q6C to distort colours, which resulted in a very good final outcome. After calibration, the problem of excessive warming of scenes in SDR and over-cooling of the image in HDR disappeared. However, it's worth analysing the brightness characteristics more closely. While in SDR content there are few complaints – the picture looks really good, especially in older films, TV programmes, or on YouTube – it performs much worse with HDR content. Analysis of the EOTF curve suggests that everything is fine, but in practice (EOTF in films), the limitations of the actual construction become evident. This model tends to excessively brighten small parts of the frame, while in other situations, it darkens the entire scene too much. The effect of calibration is therefore undeniable, and in terms of colourimetry, ChooseTV 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 Hisense U8NQ unfortunately struggles. The "Smooth and Gradient Picture" feature does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with a lot of subtle tonal transitions.

As for the digital processing, or so-called upscaling, the scene with the model is rendered correctly — her outline is clear, without significant cropping. Similarly, thin lines, like tree branches, have slight jaggedness, but the overall image looks plastically and softly, providing a good impression. Unfortunately, there is also an issue with so-called overscan, which results in cropping of the image at the edges. This can be annoying when watching content such as news, where the bottom information bars may be partially invisible.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content is presented acceptably, and due to the lack of overscan issues, the image is displayed in full without any cropping. However, don’t expect miracles – materials of very low quality won’t gain a second life here, as the image processor has its limitations.

On thin lines and details, there is noticeable jaggedness, which reveals the lack of more advanced image enhancement algorithms. It's also a shame that the C69K / Q6C lacks a feature for smoothing tonal transitions. As a result, in older films or video materials, color banding can be visible and may become distracting during extended viewing.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The TV will also satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" enhancer that allows users to control the smoothness of the image — you can choose whether you prefer a more "framey" picture or a smoother, cinematic effect. This provides great flexibility in adjusting the motion quality to individual viewer preferences.

The use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. This represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz at 4K. The difference is particularly noticeable when watching sports or gaming – the ball, players, and dynamic action in games are displayed more clearly and without losing detail. An interesting feature is also the panel's ability to operate at 240 Hz (which the manufacturer does not officially mention) – we will revisit 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 own preferences using two simple sliders. We can either leave the visible film frame or opt for a very smooth one, "

Hisense U8NQ offers everything a player might need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an incredibly smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature allows the image to adjust to variable frames per second, eliminating stuttering and tearing, translating to exceptionally smooth gaming. Additionally, the television is equipped with the ALLM (auto low latency mode) feature, which automatically switches the TV to game mode, minimising input lag. This means players can enjoy responsive gameplay without needing 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 features a "Game Bar" — a function that allows quick access to essential 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 gaming. This may be disappointing for players expecting optimal detail reproduction in HDR scenes. Nonetheless, 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 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, which is a panel with the most important settings within easy reach – handy when we want to change something quickly during gameplay (e.g., aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. However, this option is mainly for PC gamers looking to go below native 4K resolution. In this case, the television can spread its wings and show additional smoothness, particularly in fast e-sport titles. For consoles, we stick to the standard limit of 120 Hz, but even so, the possibilities are truly extensive. The only minor criticism is slight ghosting that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.
