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

When it comes to HDR effect quality, the E7Q PRO unfortunately is not a television that impresses with brightness alone. In real film materials, we measured around 250–300 nits, which is simply not enough for HDR to look spectacular. There's a lack of that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble more of a good SDR than true cinematic HDR. The silver lining in all this is the colours. We managed to confirm that the E7Q PRO is a PFS type television, which means it has an additional filter that improves colour gamut coverage. Because of this, even if the brightness doesn't deliver, the colours in HDR content can be properly saturated and pleasing to the eye, without the impression of a "washed-out" image.

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in 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, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. 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%.

In terms of colour reproduction, we tested the Hisense E7Q Pro in Movie mode, which undoubtedly turned out to be the best built-in preset. It is this mode, unlike the Eco, Standard, or Dynamic settings, that offers the most natural colours straight out of the box. While no factory mode is completely free of flaws, the E7Q Pro deserves high praise for its colour rendition in standard SDR content. The colour palette has been very well tuned, and errors in the Color Checker tests often did not exceed a value of 3, which is an outstanding result rarely seen in such affordable TVs. The only drawback we noted in SDR is the tendency to darken certain elements of the image, as indicated by a slightly raised gamma curve. The TV performs slightly worse with colours in HDR mode. Here, colour errors become noticeable to the naked eye, mainly due to a deficiency of blue in the white balance. This causes the colours on screen to appear too warm, and for some viewers, they may seem almost "too cinematic." Of course, to improve these parameters, we proceeded with professional calibration.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed 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 profile 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 would give 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 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's worth noting that the E7Q Pro unit we tested happened to be exceptionally well-made from 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 adjustments. The biggest beneficiary of professional calibration was undoubtedly HDR mode. This is where we did the most work, which brought spectacular results. We successfully tamed the excessive warmth of the image, caused by a factory shortfall in blue colour. After calibration, colour errors were reduced to a significantly lower level, which will certainly please those watching 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, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, 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 colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well here and doesn't fall dramatically short of much more expensive, advanced TVs. Lower quality materials can look clear and reasonable, without the impression that the image is artificially "overdrawn." The smoothing function, however, presents a bit worse. Yes, it can be effective and improve tonal transitions in low-quality materials, but at the same time, it can introduce unwanted effects. Sometimes it removes film grain or adds unwanted artifacts, giving the image a more "digital" character. Therefore, we mainly recommend it to those who prefer a smoother, less cinematic image style.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

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

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

E7Q PRO is a phenomenal screen for gamers. Besides the typical "issue" with Hisense, which is the lack of support for the HGiG format due to constantly active tone mapping, we get practically everything one could expect from a TV that is supposed to have a gaming tag. There are two HDMI 2.1 ports, along with a full set of key features. We have variable refresh rate, automatic switching to game mode, and support for 4K at 120 Hz. On top of that, all the important settings are at hand in the clear Game Bar. This tool not only looks modern, but it also has a typically "gaming" edge and actually makes life easier while gaming.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.
