Hisense U7KQ vs Hisense E7Q PRO / E79Q PRO

Describing the HDR effect in the Hisense U7KQ 100-inch model is not straightforward and requires context. In bright scenes, the TV achieves over a thousand nits of brightness, delivering vivid and realistic images that meet expectations for this class of equipment. However, performance declines in darker scenes. In mixed shots, like those in Gemini Man, the TV maintains a brightness level of 700 nits, providing good quality. The issue arises in very dark scenes with small light sources, where the TV limits its capabilities to preserve black levels. This results in a lack of the "WOW" effect, making such frames feel less like true HDR.

If 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 about 250–300 nits, which is simply too little for HDR to look spectacular. It lacks that "spark" in bright details, flashes, and light effects, and in many HDR scenes, it can resemble better SDR than true cinematic HDR. A consolation in all of this is the colors. We managed to confirm that the E7Q PRO is a PFS type television, meaning it has an additional filter that enhances color gamut coverage. As a result, even if the brightness doesn't deliver, the colors in HDR content can be adequately saturated and pleasant to the eye, without the feeling of a "faded" image.

The best factory mode we measured on the Hisense U7KQ was "Filmmaker." However, its performance still left room for improvement. Let's start with the gamma chart, which affects image depth and contrast. The orange line, which represents the REC.709 standard reference value, begins at 2.4. Looking at the white multi-point line that indicates the measured value, a noticeable drop to 2.0 indicates a decrease in contrast, making the image lack depth and resulting in a "milky" effect. Next, we checked the white balance, which, although minor, can drastically affect the overall image quality if poorly calibrated. Initially, the chart was fine, but red and blue began to dominate, giving all test materials an unpleasant tint. Fortunately, with the advanced colour management system (CMS) and 2- and 20-point grayscale adjustment tools, we managed to significantly improve SDR material performance, as reflected in low deltaE errors and well-calibrated gamma and white balance.

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

In SDR mode, after calibration, the Hisense 100U7KQ performs excellently. Regarding colour reproduction there is nothing to criticise – both pastel and highly saturated colours are displayed according to the Rec. 709 standard, ensuring the image looks natural and in line with the director's intent. Viewers can enjoy an authentic visual experience, with colours and tonal subtleties faithfully represented.

In HDR mode, however, there is a noticeable boost in bright tones. The TV attempts to enhance the image, which can lead to an artificial brightening. This phenomenon becomes more apparent in real scenes, where bright areas of the image may be excessively brightened. While colours in HDR are generally good, they are intentionally over-boosted by the manufacturer, which can affect their naturalness.

This approach to HDR may not appeal to everyone, particularly those who value authenticity and fidelity to the original colours. However, for those who prefer more dynamic and vivid images, the boost in bright tones can add extra brilliance and impact to scenes.

In the case of materials with a standard color range (SDR), our efforts in Filmmaker mode turned out to be largely cosmetic 😉. We mainly focused on gentle white balance correction and gamma curve adjustment, which allowed us to recover details in the darker parts of the image that previously tended to get lost. It is worth noting, however, 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 the HDR mode. This is where we did the most work, which yielded spectacular results. We managed to effectively tame the excessive warmth of the image, caused by a factory deficiency of blue color. After calibration, color 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.

Although the Hisense 100U7KQ is equipped with a feature to reduce posterisation called "Smooth Gradation," we did not notice a significant effect from its operation. Material subjected to strong compression, such as YouTube videos, still showed uneven, cut-off tonal transitions, which did not look particularly favourable. While this is the fault of the material itself and not the television, it would be beneficial if there were a function to mask these problems, similar to screens from competing brands.

The image scaling, which is crucial when playing lower resolution content, is average. Details are not excessively blurry, and the image is not "smeared," but there is noticeable aliasing on the edges of objects, such as branches, and a halo effect around characters and text. While the television performs fairly well, there is still room for improvement, particularly in the context of displaying lower-quality material.

When it comes to upscaling and digital image processing, the E7Q PRO deserves praise. The scaling performs really well here and does not fall drastically behind much more expensive, advanced televisions. Lower-quality materials can look clean and sensible, without the impression that the image is artificially "overdrawn." However, the smoothing function presents a bit worse. It can indeed 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 style of image.

The Hisense 100U7KQ TV correctly receives a 4K signal up to 144 Hz, allowing for very smooth images in high resolution. When the resolution is reduced to Full HD, the TV can handle up to 240 Hz, but this signal can only be obtained from a PC. However, the use of this feature is limited by several factors.

Firstly, Full HD resolution on a large TV screen may feel insufficient, affecting image quality. Additionally, the panel's response time isn't fast enough to fully utilise the 240 Hz refresh rate. As a result, at such a high refresh rate, significant overdrive occurs, leading to noticeable motion blur and "ghosting" behind moving objects.

The motion smoothing feature, which works up to 120 Hz, is also worth noting. This is especially useful for sports and movies where motion fluidity is crucial. The TV provides stable operation of this feature, minimising generated artefacts. Motion fluidity can be adjusted using two sliders – one for smoothness in movies and another for reducing blur in sports content.

In summary, while the Hisense 100U7KQ TV offers impressive image refresh rates, the panel's response time and resolution may affect the overall benefits of these features. Nevertheless, the motion smoothing function enhances the viewing experience of dynamic content.

In the category of motion blur and fluidity of movement, 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 the menu displays more options for smoothing the image. Among other things, we have frame interpolation options, which allows us to adjust the fluidity for sports or for movies, depending on whether we prefer a more cinematic character or a "theatrical" smoothness.

The Hisense U7KQ TV supports all the key features when using Xbox or PlayStation consoles, including high refresh rates, low input lag, and a game bar. Most of these features work well, providing a satisfying gaming experience.

However, VRR (Variable Refresh Rate) technology does not perform optimally. When activated, VRR disables the local dimming function, significantly reducing image quality. In VRR mode, the TV struggles with maintaining good contrast and high brightness in HDR, resulting in unsatisfactory image quality. As a result, VRR mode may be infrequently used by gamers due to these limitations.

Additionally, the TV does not support the HGIG (HDR Gaming Interest Group) mode, which optimises HDR image quality in games. Without this mode, tone mapping issues arise in the TV and the console, leading to lower-quality HDR games, which could affect the overall gaming experience.

In summary, while the Hisense U7KQ offers many features for gamers, certain key aspects, such as VRR performance and HGIG support, may not meet the expectations of more demanding users. Nonetheless, the TV supports most standard gaming functions, making it suitable for gamers.

The E7Q PRO is a phenomenal screen for gamers. Aside from the typical "thorn" of Hisense, which is the lack of support for the HGiG format due to the constantly active tone mapping, we practically get everything one might expect from a television that is supposed 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. On top of that, all the most important settings are at hand in a clear Game Bar. This tool not only looks modern but also has a distinctly "gaming" edge and actually makes life easier while playing.
