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 nearly identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments such as 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 need to be shown against a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the most. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LEDs 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 performance offers reasons to be pleased. Coverage of the DCI-P3 colour gamut at around 94% is a very good result, and the applied layer of quantum dots (more precisely, PFS) does its job – the colours are saturated and vibrant, especially with 4K content.

In terms of brightness, TCL C69K / Q6C is a moderate model. In optimal film conditions, it shows its full potential, achieving a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a cinematic shimmer. However, it should be noted that when managing backlight zones, there are situations where parts of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimisation of the algorithms; however, considering the technical parameters in this price range, the design itself still presents very well.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a possibly neutral image close to the director's vision. Unfortunately – although it doesn't look bad on paper (the colour reproduction errors are not significant), in practice the image appears not entirely natural. The reason? An overly strong boost in blue colour and a lack of red in the white balance. The effect? Scenes look cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness mapping curve for HDR content (EOTF) shows that the television can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far in this. On the other hand, larger, very bright areas can be excessively brightened, 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 made its debut 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 daily film and series viewings. Unfortunately, as is often the case, best does not mean perfect. In SDR material, the image proved to be too warm, with a pronounced red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should, due to an excess of blue. Additionally, there is the characteristic of brightness, which at times resulted in overexposure. In practice, this translated into quite noticeable errors in colour tests, which is difficult to accept in a mode branded as "from the creators."

The calibration of the Movie mode yielded really good results, especially when it comes to SDR content. We managed to balance the white levels, which made the image look more natural – it appeared almost reference-quality. The colours were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we switched to HDR materials, familiar issues from the U7Q model returned. The television still likes to "do its own thing," as evident from the analysis of the brightness characteristic EOTF – despite calibration, the E8Q still dimmed fine details in the shadows, while the bright areas of the screen could be excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it must be acknowledged 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 apparent, and it is worth keeping this in mind.

Through white balance correction, we were able to significantly reduce the tendency of C69K / Q6C to distort colours, which yielded a very good final result. After calibration, the issue of excessive warming of scenes in SDR and excessive cooling of the image in HDR disappeared. However, it is worth analysing the brightness characteristics more closely. While in SDR content it is hard to have major objections – the image looks really good, especially in older films, TV programmes or on YouTube – it performs significantly worse in the case of HDR content. Analysis of the EOTF curve suggests that everything is fine, yet in practice (EOTF in films) the limitations of the design itself become apparent. This model has a tendency to excessively brighten small parts of the frame, only to overly dim the entire scene in other situations. The effect of calibration is therefore undeniable, and in terms of colour reproduction, C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, features an "Smoothing and Gradient Image" function, but unfortunately – its effectiveness leaves much to be desired. The "Low" mode is almost imperceptible in operation, and the higher settings do not improve transitions but simply blur the details. The good news is that the function does not compromise film grain, meaning it does not worsen the structure of the image. On the plus side, scaling is commendable. The television is able to sensibly upscale older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although 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 appears acceptable, and thanks to the lack of overscan issues, the image is displayed in full without any cropping. However, one should not expect miracles – very low-quality materials will not gain a second life here, as the image processor has its limitations.

Thin lines and details exhibit characteristic tearing, which reveals the absence of more advanced image enhancement algorithms. It is also a pity that the C69K / Q6C lacks a tone transition smoothing feature. As a result, in older films or video materials, banding of colours can be visible and may become distracting during prolonged viewing.

Similar to the U7Q, the E8Q model is a fast television designed for dynamic content. It supports a refresh rate of 144 Hz 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 offers two sliders that allow you to customise the picture to your preference – whether more cinematic with the film frame preserved or highly smoothed, almost "series-like". It's good that the manufacturer provides a choice here instead of imposing one style. On sports material, live broadcasts, or in games – movement looks clean and stable. Of course, it is not at the OLED level, 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 in 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 loss of detail. Another interesting feature is the panel's ability to work 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, "

Hisense E8Q does not hide its gaming heritage. Even 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 switching to game mode (ALLM)? That's there too. Additionally, there is impressive refresh rate – 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 – similar to the U7Q – is support for HGiG. It’s a shame, as this feature facilitates adjusting the brightness curve to the capabilities of a specific television, improving visual compatibility with the intentions of HDR game creators. Without it, one has to manually fiddle with the settings, which does not always yield a satisfactory result.

TCL C69K / Q6C is a television that can confidently be described as 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 is a practical Game Bar, which is a panel with the most important settings conveniently at hand – useful when we want to change something quickly during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is particularly noteworthy. However, this option is mainly for PC gamers who will operate below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. For consoles, we stick to the classic limit of 120 Hz, but even so, the capabilities are truly extensive. The only downside is a slight ghosting that can occasionally be seen in dynamic scenes. Other than that, C69K / Q6C offers everything that gamers expect from a television.
