Hisense U7NQ vs TCL C6KS / C69KS / Q6CS

The Hisense U7NQ 65 television demonstrated significant capabilities on the luminance chart, exceeding the 1000-nit barrier and achieving very high brightness results without issue in the first, third, and fifth test scenes. However, as before, in the second and fourth test scenes, for example from the film Sicario 2, there are significant problems with maintaining brightness, and the results around 200 nits are very disappointing. Despite a large number of dimming zones, the algorithm in the television responsible for controlling these zones is unable to react appropriately — in this case, it significantly dims small elements like the moon or the light from a helicopter. The bright light that should blind us is too dim to be called an HDR effect. Nevertheless, it is worth praising the television for its high coverage of the DCI-P3 colour gamut at 96%, which allows it to accurately reproduce most film scenes.

And how does the issue of HDR look? Here the C6KS performs quite well and – as is becoming a recurring theme in this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must remember the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible black levels. It’s a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional micro-details that could cause grayness on the screen. Such is the nature of local dimming technology in this price range, and one must be aware of it. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the tagline of QLED technology. Thanks to this, the colors are saturated and vibrant – our measurements showed that the coverage of a wide color gamut reaches 92% here.

The Chinese manufacturer offers various picture settings with its televisions, but the best mode in this model is undoubtedly the Filmmaker Mode. Despite its name, this mode has its issues: the white balance, although roughly correct, is characterized by a strong dominance of warm tones due to the kick of red colour, both in 4K and HD materials. The Colour Checker test confirms these errors — deviations in samples are visible in inappropriate shades. As for the brightness characteristics, the gamma responsible for HD materials shows values below 2.4, leading to some brightening of the screen. Meanwhile, the EOTF curve shows the television's problems with displaying small light elements, as confirmed by the previously described paragraphs.

Unlike the more expensive C6K model, the tested C6KS does not have an option labeled Filmmaker Mode in the menu. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of color reproduction, the absence of this specific label makes virtually no difference. The best available Film/Cinema mode here offers nearly identical picture characteristics to the aforementioned Filmmaker mode in the more expensive model. So we get a very similar image, just under a different name. So if you were wondering whether paying extra for the C6K gives you better colors – the answer is: no, in both cases the base is the same and requires slight adjustments.

Hisense televisions offer many tools for image correction, allowing users to adjust settings to their preferences. Therefore, we decided to utilize these capabilities to bring the image quality closer to reference standards. In the case of white balance, we managed to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD materials. A similar improvement was noticed in the brightness characteristics. Gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail representation in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was the calibration of the EOTF curve, which is responsible for brightness in 4K materials. At first glance, the EOTF value appeared almost perfect, but detailed tests showed a slightly different outcome. Upon closer inspection—especially using the filter on the right side of the EOTF chart—we noticed how the television manipulated 4K film materials, often significantly boosting brightness. This effect was particularly noticeable in scenes from films such as Pan and Billy Lynn, where the television attempted to artificially increase the brightness of elements, affecting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the final effect should be satisfactory, especially if they aim to bring image quality closer to professional reference standards.

Thanks to the white balance adjustment, the tendency of the C69KS to distort colors has been effectively reduced, leading to a very good final effect. After calibration, we won't see excessive warmth in SDR scenes or overly cool tones in HDR. However, it's worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, television programs, or materials from YouTube. It is much more difficult to evaluate the performance of the television in HDR. Analysis of the EOTF curve suggests correct behavior, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of color reproduction, but certain limitations arising from the operation of local dimming and the way it is controlled by the C69KS cannot be avoided, as we also saw in the C6K test.

When it comes to smoothing tonal transitions, despite the presence of the "Smooth and Gradient Image" feature in the test sequence, we did not notice that the feature added anything — we recommend turning it off. As for upscaling, the television handled our model well, and the branches in the background are not excessively jagged — the image seems quite plastic. However, it was slightly cropped by the so-called overscan.

C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a significant amount of detail is preserved, and the algorithm adds a subtle "rounding" effect to sharp edges, making the image appear more cohesive. However, the smoothing of tonal transitions is lacking. The television practically cannot improve them, leaving the image in a somewhat raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth motion. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction feature minimizes the effect of so-called judder, which is the unpleasant stuttering of the image, particularly noticeable at lower frame rates. On the other hand, motion blur reduction helps sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for motion blur, the TV has a decent response time, so excessive blurriness is not visible, except in specific situations, such as the test with the little green alien on a dark background. In such cases, slight artifacts may appear, but overall, the TV handles dynamic images well, providing satisfactory motion quality.

C69KS offers a simplified motion improvement panel in movies, allowing you to adjust the intensity of the effect using a slider. This makes it easy to match the smoothness to your own preferences. The possibility of using higher refresh rates is also a plus – even though the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p allows you to enable 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, but in practice, the image at these settings suffers from significant motion blur. The effect is noticeable enough that the overall experience feels simply mediocre and loses its appeal in everyday use.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, providing an incredibly smooth image, especially in dynamic action games. The VRR (Variable Refresh Rate) feature ensures that the image adapts to changing frames per second, eliminating stuttering and tearing. Additionally, there is an ALLM (Auto Low Latency Mode) feature that automatically switches the TV to game mode, minimizing input lag.

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and vivid colors in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to essential settings during gameplay, as well as support for G-Sync technology, which further reduces image tearing.

Unfortunately, despite the wide range of features, support for the most popular HDR format in gaming — HGiG — is lacking. This may be disappointing for gamers who expect optimal detail representation in HDR scenes. Nevertheless, the remaining features make the Hisense U7NQ a solid choice for any console gaming enthusiast.

If we overlook the smearing and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything you can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a reasonably functioning HGiG. The TV can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings during gaming. As a result — despite a few limitations — the C69KS can be a truly successful screen for gamers.
