Hisense E8Q vs TCL C6KS / C69KS / Q6CS

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
