Hisense U8Q vs TCL C69K / Q6C

When it comes to HDR, Hisense U8Q shows its claws. On paper, meaning in synthetic measurement tests, the television can "score" nearly 4000 nits of peak brightness. That's a value that most models can only envy. In practice, this translates to very strong lighting effects in films – in some scenes, we managed to measure a real 1500 to 2000 nits, which is a level usually reserved for the absolute top of televisions on the market.

Of course, it's not always that perfect. With small, pinpoint elements, brightness can drop – a good example is scene number 4 from the movie Sicario 2, where instead of thousands of nits, we get around 500. But it's worth noting that the effect doesn't vanish completely – the light is still visible, and the image doesn't feel artificially dimmed. This is a typical drawback of Mini LEDs, so it's hard to consider it a significant minus.

On the huge plus side, color reproduction deserves high praise. Thanks to additional coatings that improve color saturation, the U8Q nearly covers the full DCI-P3 color space (98%), and in the case of the wider BT.2020 gamut, it achieved a score of over 80%. This is an excellent result, making HDR films look juicy, vibrant, and simply very cinematic.

In terms of brightness, TCL C69K / Q6C is a moderate model. Under 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, providing a cinematic sparkle. However, it should be noted that when managing the backlight zones, there are situations where some elements of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimization of algorithms, though considering the technical parameters in this price range, the construction still looks very good.

We have to admit that when the U8Q arrived at our editorial office, we were slightly surprised… and positively so. Usually, televisions require immediate white balance correction – it can be too warm or too cold, which immediately leads to strange color errors. Meanwhile, here the situation looks really good right out of the box. Of course, we are talking about our unit, so there’s no guarantee that every model will be tuned as well, but in our case, the first impressions were very positive. The only more pronounced issue was related to how the television manages brightness. Looking at the EOTF chart, it is evident that the U8Q tends to brighten small elements on the screen. This, in turn, caused what we mentioned earlier – slight overexposures and the impression that the entire scene can sometimes be a bit too bright. However, this is not a flaw that undermines the image, rather it is a characteristic effect of this model.

The Filmmaker mode, which has arrived 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 everyday viewing of movies and series. Unfortunately, as is often the case, best does not mean perfect. In SDR content, the image turned out to be too warm, with a strong red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should have, due to an excess of blue color. Additionally, the brightness characteristics sometimes resulted in overexposure. In practice, this translated to quite noticeable errors in color tests, which is hard to accept in a mode labeled as “by the creators.”

Of course, we wouldn't be ourselves if we didn't make adjustments to the white balance. After calibration, we managed to align the SDR signal to near perfection – older movies, YouTube content, and classic television looked almost perfect on the U8Q. This is truly an outstanding level that shows this model can do a lot if given a little help. Unfortunately, the situation is different with HDR content. The colors themselves aren't a major issue, but the biggest flaw of the U8Q remains the EOTF brightness characteristics. In practice, the TV tends to "blow out" beyond how the image should look in its original form. It's that slight "blown out" effect we saw earlier in comparisons with the best screens on the market. It's a bit of a shame that this characteristic can't be fully tamed – if we could maintain similarly good control over brightness in HDR as we do in SDR, we would have an absolutely reference-quality image.

Through white balance adjustment, we were able to significantly reduce the tendency of C69K / Q6C to distort colors, which resulted in a very good final outcome. After calibration, the issue of excessive warmth in SDR scenes and overly cool images in HDR disappeared. However, it is worth closely analyzing brightness characteristics. While there are few complaints about SDR content - the image looks really good, especially in older movies, TV programs, or on YouTube - the situation is 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 design become apparent. This model tends to excessively brighten small parts of the frame, while in other situations it dims the entire scene too much. The effect of calibration is undeniable, and in terms of color accuracy, C69K / Q6C gains a lot. Unfortunately, certain limitations resulting from local dimming management simply cannot be overcome.

The Hisense U8Q handles lower-quality materials quite well. The TV can smooth out tonal transitions thanks to the "Smooth and Gradient Picture" feature – it works best when set to Medium. At that setting, it nicely reduces unwanted bands and unevenness in the image, but importantly, it does not remove cinematic grain or fine details.

The upscaling itself is also at a good level. Images from lower resolutions look smooth and soft, at times even a bit too much – we get a plastic effect that may not appeal to everyone. Fortunately, this can be easily adjusted with the sharpness slider to fit personal preferences.

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

On thin lines and details, one can see characteristic jitter, indicating a lack of more advanced image enhancement algorithms. It's also a pity that the C69K / Q6C lacks the function for smoothing tonal transitions. As a result, in older movies or video materials, color banding can be noticeable and may become distracting during longer viewing sessions.

Hisense U8Q has a display that can refresh the image up to 165 Hz in 4K resolution. In practice, this will mainly be utilized by PC gamers, but as they say – it’s better to have it than not 😊. For movies and series, we have a built-in smoothness enhancer called Ultra Smooth Motion. In the settings, it can be easily adjusted to personal preferences – whether we want more of a "cinematic" frame rate or a smooth, theatrical spectacle.

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 at 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 losing details. An interesting feature is also the ability of the panel to operate 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, "

In terms of features, the Hisense U8Q has practically everything one could expect from a modern gaming television. Thanks to the new processor, the manufacturer has managed to implement as many as three HDMI 2.1 ports, so there is no problem connecting multiple consoles or a computer. In addition, it includes all the key technologies – Game Bar with parameter monitoring, variable refresh rate (VRR), automatic low latency mode (ALLM)... in short, a complete set.

But as is often the case with Hisense, it falls a bit short of perfection. The biggest drawback remains the lack of support for the HGiG format, which allows you to adjust the television's brightness to the console and get the most out of HDR in games. It's a shame because if this feature were included, we would have a device practically made for gamers. As it stands, the U8Q remains "just" a very good choice 😉

TCL C69K / Q6C is a television that can boldly be called 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's a practical Game Bar, which is a panel with the most important settings right at hand – useful when we want to quickly change something during gameplay (e.g., aspect ratio: Yes, it’s possible!). The wide range of VRR, reaching up to 240 Hz, is noteworthy. This option is primarily for PC gamers who will lower the resolution below native 4K. In that case, the TV can spread its wings and show additional smoothness, especially in fast esports titles. For consoles, we stick to the classic limit of 120 Hz, but the possibilities are still quite broad. The only drawback is slight motion blur that can sometimes be seen in dynamic scenes. Other than that, C69K / Q6C offers everything gamers expect from a television.
