Hisense E8Q vs TCL C69K / Q6C

Since the E8Q is a twin of the U7Q, it’s no surprise that the quality of the HDR effect is almost identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Fragments like the flashes of light in “The Meg” or shots of the sun in “Life of Pi” can indeed evoke a “wow” effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details are supposed to be displayed on a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming 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 won't always be fully preserved. Fortunately, the color reproduction offers reasons to be satisfied. A coverage of the DCI-P3 color gamut at around 94% is a very good result, and the applied quantum dot layer (more specifically, PFS) does its job – colors are saturated and vibrant, especially with 4K content.

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.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a neutral image close to the director's vision. Unfortunately - although on paper it doesn't look bad (the color reproduction errors are not significant), in practice the image feels somewhat unnatural. The reason? Too strong an increase in blue and a lack of red in the white balance. The effect? The scenes look cool, and the white appears 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 of the screen to maintain contrast - but sometimes it goes too far. On the other hand, it can excessively brighten larger, very bright parts, which disrupts tonal balance. This is a compromise that may not suit everyone – especially if you want an as faithful image as possible right out of the box.

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.”

The calibration of the Movie mode brought really good results, especially regarding SDR content. The white balance was successfully adjusted, which gave the image a natural look – it appeared almost reference-level. The colors were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we moved to HDR materials, the well-known problems from the U7Q model returned. The TV still tends to “do things its own way,” which is evident from the analysis of the EOTF brightness characteristic – despite calibration, the E8Q still dimmed small details in the shadows, while the bright areas of the screen could sometimes be excessively boosted. In practice, this means that in darker scenes, some of the tiniest details could simply disappear. Although it must be admitted that the entire calibration process brought a lot of good, not everything can be circumvented – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its design limitations become noticeable, and it is worth keeping this in mind.

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.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions is often useful. The Hisense E8Q, like the U7Q, has the "Smooth and Gradient Picture" feature, but unfortunately, its effectiveness leaves much to be desired. The “Low” setting is almost imperceptible in operation, while higher settings simply blur details instead of improving transitions. The good news is that the feature does not compromise the film grain, which allows it to maintain the image structure. On the plus side, the scaling is commendable. The television can fairly sensibly transform older content to a higher resolution—without artificially emphasizing contours or excessive sharpening. Though it does not match the best models in this category, it performs quite well for its class.

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.

Like the U7Q, the E8Q model is a fast television designed for dynamic content. It supports 144 Hz refresh rates in 4K resolution, and if for some reason someone is still gaming in Full HD, it can achieve even 240 Hz. This is a significant advantage, especially for PC users looking for maximum fluidity. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode provides us with two sliders, allowing for personalized image settings – whether it’s more cinematic with preserved film frames or heavily smoothed, almost "series-like." It’s good that the manufacturer gives a choice here instead of imposing one style. On sports materials, live broadcasts, or in games – motion appears clean and stable. Sure, it’s not at the level of OLEDs, but for this price range, the E8Q performs really well.

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, "

The Hisense E8Q does not hide its gaming pedigree. The specification alone reveals that we are dealing with a television that will work great as a gaming screen. Variable Refresh Rate (VRR)? Yes. Automatic low latency mode (ALLM)? It's there too. Additionally, there is impressive refreshment – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything works smoothly and without major surprises. The only missing element – like in the U7Q – remains support for HGiG. It's a pity, because this feature makes it easier to match the brightness curve to the capabilities of a particular television, improving visual consistency with the intentions of HDR game creators. Without it, one has to manually tweak the settings, which does not always yield a satisfying result.

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.
