Hisense E7Q / E79Q vs TCL C6KS / C69KS / Q6CS

Hisense E7Q / E79Q is a television with average brightness, whose peak luminance level is around 350-380 nits. This is an absolute minimum that allows for watching HDR content in a way that is close to the creators' intentions, although without a clear "wow" effect. The results of synthetic tests on white images have been confirmed in practice – in movie scenes, the bright parts of the image are stable and fairly uniform, but it is hard to speak of a true "lighting impact" here. In everyday use, for example, while watching Netflix or YouTube, the HDR effect is acceptable and is completely sufficient for most users. However, it must be stated clearly – this is not the level of top screens, and one should not expect that at this price point. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it is a PFS LED QLED panel, utilizing an additional phosphor layer that improves color reproduction. The measured range of the DCI-P3 palette is around 92%, which means that the colors in most scenes are vibrant, well-saturated, and pleasing to the eye, especially for this price range.

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.

In Filmmaker mode, the Hisense E7Q / E79Q television was able to really surprise positively. Even after the first measurements, it turned out that the white balance is quite well calibrated, and the only minor deviation was a slight tendency toward a purple hue, which we mentioned earlier. However, this did not significantly affect the overall character of the image – it remained coherent and pleasant to perceive. A much larger problem turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening the contrast and taking away its depth. Gamma values could drop from the reference 2.4 down to about 1.9, making the image appear as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

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 biggest beneficiary of calibration for the Hisense E7Q / E79Q turned out to be the SDR mode without a doubt. It managed to achieve nearly perfect picture quality – most errors in the Color Checker test dropped below a value of 3, and often even below 2, which is a remarkable result for this class of equipment. The greatest improvement came from aligning the brightness characteristic (gamma), making the picture no longer look washed out and regaining its natural depth. In HDR content, colors were also improved, and the purple tint we mentioned earlier was eliminated, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite strongly, oversaturating some colors. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor problems with excessive brightening. Despite this flaw and the construction limitations that arise with HDR content, the Hisense E7Q / E79Q gained a lot after calibration. In everyday use, the television presents a cohesive, natural, and pleasant-to-the-eye picture, and the difference compared to factory settings is truly vast.

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 Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest features of this television. It is clear that the manufacturer opted for simplicity rather than advanced image processing algorithms. The television does not offer any functions for smoothing tonal transitions or systems for improving image clarity, which means that lower resolution materials simply look very raw. On the screen, subtle compression edges can be noticed, which better processors in other models can effectively hide.

During tests of HD materials, we noticed that the E7Q tries to artificially enhance detail, which sometimes works and sometimes has the opposite effect – the image becomes soft, slightly smeared, at times even "watery." There is no aggressive sharpening that ruins naturalness, but there is also no finesse in detailing that better image processors offer.

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.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so 4K sports fans may feel a slight disappointment – we simply won't see such smooth images here as in more expensive models with higher refresh rates. Fortunately, when it comes to movies, the situation is much better. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to adjust the image to their preferences – more cinematic with a visible frame or smoother, in a theatrical style.

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.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it doesn't support 4K signal at 120 Hz. However, the manufacturer has included a set of features that until recently could only be found in more expensive models. There is ALLM, or automatic switching to low-latency mode, which allows the television to activate game mode with very low input lag. We also have VRR, functioning up to 60 Hz – this may not seem impressive on paper, but in practice, it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this level, you can change picture modes, turn on a frame rate counter, or even… a crosshair on the screen – in the Vidaa system humorously named "target point," which is a result of awkward translation by the Chinese manufacturer.

Particularly praiseworthy is the ability to play in 1080p at 120 Hz, which realistically improves the smoothness and responsiveness of the image. This way, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy significantly smoother motion. Despite the lack of 4K@120Hz, Hisense E7Q / E79Q really performs well as a television for gamers – especially those who are not looking for perfection, but a solid and fast screen for everyday gaming.

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.
