TCL C6K vs Hisense E8Q

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.

Since the E8Q is a twin of the U7Q, it’s no surprise that the HDR effect quality is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments like light flashes in “The Meg” or shots of the sun in “Life of Pi” can indeed create a “wow” effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details need to be shown against a dark background. In such situations, the dimming algorithms try to protect the contrast, but in the process, they also dim what should shine the brightest. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LED in this price segment and is not surprising – but it’s worth knowing that the HDR effect will not always be fully preserved. Fortunately, the colour reproduction provides reasons to be pleased. A coverage of the DCI-P3 palette of about 94% is a very good result, and the quantum dot layer used (more precisely, PFS) does its job – colours are saturated and vibrant, especially with 4K content.

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”.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a potentially neutral picture resembling the director's vision. Unfortunately – although it doesn't look too bad on paper (the colour reproduction errors aren't significant), in practice the image feels somewhat unnatural. The reason? The blue colour is boosted too strongly and there is a deficiency of red in the white balance. The effect? Scenes appear cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness reproduction curve for HDR content (EOTF) shows that the TV can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright areas, which disrupts tonal balance. It's a compromise that may not suit everyone – especially if you want a potentially faithful picture straight out of the box.

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.

Calibration of the Movie mode yielded really good results, especially regarding SDR content. The white balance was successfully adjusted, giving the image a natural look – it appeared almost reference-level. The colours were well-saturated, and the overall experience of the content improved significantly. Unfortunately, when we switched to HDR materials, the familiar issues from the U7Q model returned. The TV still likes to "do its own thing," as seen from the analysis of the EOTF brightness characteristics – despite calibration, the E8Q still darkened small details in the shadows, while brighter parts of the screen were sometimes excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it's worth noting that the entire calibration process brought a lot of good, not everything can be bypassed – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its construction limitations become apparent, and it's worth keeping this in mind.

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.

In the case of older materials of lower quality, gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, has a "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The "Low" setting is nearly invisible in operation, while higher settings blur details instead of improving transitions. The good news is that the feature does not compromise film grain, which means it does not degrade the structure of the image. On the positive side, scaling is commendable. The TV can reasonably convert older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it doesn't match the best models in this category, it performs quite well for its class.

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.

Similar to the U7Q, the E8Q model is a fast television designed with dynamic content in mind. It supports a 144 Hz refresh rate at 4K resolution, and if for some reason someone is still gaming in Full HD – it can even reach 240 Hz. This is a significant advantage, especially for PC users looking for maximum smoothness. In everyday use, the television performs very well. The “Ultra Motion Smoothness” mode gives us two sliders, allowing you to set the picture to your preference – whether it's more cinematic with the film frame preserved or highly smoothed, almost “TV show-like.” It's good that the manufacturer provides a choice here, instead of imposing one style. On sports material, live broadcasts, or in games – motion looks clean and stable. Sure, it’s not at the OLED level, but for this price range, the E8Q does a really good job.

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.

Hisense E8Q does not hide its gaming pedigree. Just the specifications reveal that we are dealing with a television that will perform excellently as a gaming screen. Variable Refresh Rate (VRR)? It's there. Automatic Game Mode switching (ALLM)? That's there too. Additionally, there's impressive refreshment – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything runs smoothly and without major surprises. The only missing element – similar to the U7Q – remains support for HGiG. It's a shame because this feature facilitates adjusting the brightness curve to the capabilities of the specific television, enhancing visual fidelity with the intentions of HDR game developers. Without it, manual tweaking of the settings is necessary, which does not always yield a satisfying result.
