Hisense E7Q PRO / E79Q PRO vs TCL C6KS / C69KS / Q6CS

When it comes to the quality of the HDR effect, the E7Q PRO is unfortunately not a television that can impress with brightness alone. In real film materials, we measured around 250–300 nits, which is simply too little for HDR to look spectacular. There is a lack of that "spark" in bright details, highlights, and light effects, and in many HDR scenes, it can resemble good SDR more than true cinematic HDR. The consolation in all this is the colours. We managed to confirm that the E7Q PRO is a PFS-type television, meaning it has an additional filter that improves colour gamut coverage. As a result, even if the brightness does not deliver, the colours in HDR content can be appropriately saturated and pleasing to the eye, without the feeling of a "washed-out" image.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of 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 keep in mind 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 blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which turned out to be the best built-in preset without a doubt. This mode, unlike the Eco, Standard or Dynamic settings, offers the most natural colours straight out of the box. Although no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendering in standard SDR content. The colour palette is very well tuned here, and the errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable televisions. The only drawback we noted in SDR is the tendency to darken some elements of the image, as indicated by the slightly raised gamma graph. The television performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a lack of blue in the white balance. This causes the colours on the screen to be too warm, and for some viewers, they may even seem “too cinematic.” Of course, to improve these parameters, we proceeded with professional calibration.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

In the case of materials with a standard dynamic range (SDR), our actions in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on a subtle adjustment of the white balance and equalising the gamma curve, which allowed us to recover details in the darker areas of the image that previously tended to get lost. However, it is worth noting that the E7Q Pro unit we tested was exceptionally well-made at the factory. We remind you that these parameters depend on the specific unit – with mass production, factory calibration can be random, so your unit may require slightly different intervention. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency in blue colour. After calibration, the colour errors were reduced to a significantly lower level, which will certainly please those who watch a lot of streaming content in HDR format, expecting faithful reproduction.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well and does not dramatically fall behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "enhanced." However, the smoothing function presents a bit worse. Indeed, it can be effective and improve tonal transitions in poor quality materials, but at the same time, it can introduce undesirable effects. It sometimes removes grain or adds unwanted artefacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic style of image.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

In the category of smearing and motion fluidity, the E7Q PRO has one very strong argument. At this price, Hisense has included a 120 Hz panel, and in PC mode, it can even operate at 144 Hz. This immediately provides greater possibilities in motion settings, as the menu offers more options for smoothing the image. Among other things, we have frame interpolation options, which allow us to adjust the fluidity for sports or films, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "ache" of Hisense, which is the lack of support for the HGiG format due to permanently active tone mapping, we get practically everything one can expect from a television that is to have a gaming label. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rates, automatic switching to game mode, and support for 4K at 120 Hz. Additionally, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a typically "gaming" edge and truly makes life easier while gaming.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
