Hisense U7KQ vs Hisense E7NQ PRO

Describing the HDR effect in the hundred-inch model Hisense U7KQ is not straightforward and requires a broader context. As can be seen, the results are highly variable, depending on the type of scene and the intensity of the bright effects that the television has to reproduce. In bright scenes, the device achieves over a thousand nits of brightness, translating to vivid and realistic images – these are exactly the effects we expect from equipment of this class. Unfortunately, the situation worsens in darker scenes. In mixed shots, such as those in the film "Gemini Man," the television still offers good brightness at around 700 nits, allowing for high-quality viewing. However, problems arise in very dark scenes where small light sources play a major role. The television does not fully utilise its capabilities here to avoid degrading the black levels in adjacent areas. As a result, there is no spectacular "WOW" effect, and such shots often do not give the impression of being realised in HDR technology.

Based on the luminance chart, which indicates around 550 nits, it can be considered that Hisense E7NQ PRO theoretically has the potential to somewhat "enchant" us with its HDR image. Testing various scenes from movies, we noticed that the television continually tries to balance between maintaining appropriate brightness and preserving the deepest blacks. In favourable conditions – such as in a scene from “The Meg”, where the screen is flooded with bright light – this brightness can indeed impress us. At such moments, we feel that HDR actually adds that "something" to the image. Unfortunately, when difficult shots with fine, bright elements on a dark background appear on the screen, the situation looks much worse. Brightness then drops to 200-300 nits, which is definitely too little to really distinguish HDR from standard SDR.

It is clear that the television is trying, but the hardware limitations – mainly the small number of local dimming zones – prevent it from fully spreading its wings. The end result can therefore be quite inconsistent and as average as the contrast tests. On the plus side, it deserves credit for its impressive coverage of the DCI-P3 colour gamut at 97%. This allows the television to present a truly wide range of colours, which, in the right scenes, can give us at least a glimpse of the real HDR effect. It’s just a shame that the whole picture isn't complemented by better control of brightness and contrast.

The best factory mode we measured was “Filmmaker”. Despite this, its characteristics left a lot to be desired. Let’s take a look at the gamma chart, which is responsible for the depth and contrast of the image. First, we'll note the orange line running through the middle of the graph, starting at point 2.4. This is the reference value of the REC.709 standard. Now let’s look at the measured value, marked by a white, connected multi-point. Such a clear drop in gamma to a value of 2.0 meant a significant reduction in contrast, resulting in the image lacking appropriate depth, and the so-called “milk” effect was noticeable. The next thing we tested was the white balance. Though seemingly minor, if poorly adjusted, it can change the entire characteristic of the image. While the beginning of the chart looked quite promising, as we progressed further, the chart began to be dominated by two colours: red and blue. Due to the current state of affairs, all the materials we used for testing had an unpleasant tint in those colours. However, thanks to rich calibration tools, such as an advanced colour management system (CMS) and 2- and 20-point grey scale adjustments, we were able to significantly improve the display's performance in SDR materials, as confirmed by low deltaE errors and very well-modeled gamma and white balance.

When we took our copy of Hisense E7NQ PRO out of the box, we immediately started checking the available picture modes. Among them, the Filmmaker mode seemed the most promising, although it wasn't without its flaws. With standard SDR content, we noticed a clear tendency to overemphasise red, making the picture appear unnaturally warm. This was particularly evident in the comparison photo attached below. Conversely, when we switched to HDR content, the situation took a turn in the opposite direction. This time, blue was dominant, and there was hardly any red, resulting in a cool, at times almost "store-like" appearance — although not as drastic as in modes specifically designed for showcasing in displays. As a result, in our tests assessing colour reproduction, these disturbances in colour balance led to significant errors.

Additionally, the television had trouble reproducing brightness characteristics. At lower resolutions, it clearly brightened the darkest elements of the image, and with HDR content, the brightness curve (eotf) simply wouldn't align as it should. Initially, the television excessively darkened the smallest details, only to then over-brighten larger areas. Fortunately, the E7NQ PRO provides us with a lot of calibration tools, so knowing there was potential within it, we decided to take matters into our own hands and try to set it up to eliminate these issues.

In SDR mode, after calibration, the Hisense 100U7KQ television performs excellently. There is nothing to fault in terms of colour reproduction - both pastel and deeply saturated hues are displayed according to the Rec. 709 standard. This ensures that the image looks natural and in line with the director's vision. As a result, 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 television tries to enhance the image, which can lead to artificial brightening. This phenomenon becomes even more apparent in real scenes, where bright parts of the image can be excessively amplified. Although colours in HDR are generally good, they are intentionally boosted too much by the manufacturer, which may affect their naturalness.

This manufacturer's approach to displaying images in HDR mode may not be to everyone's taste, especially those who value authenticity and fidelity to original colours. However, for those who prefer more dynamic and vivid images, this bright tone enhancement can be an appealing solution, adding extra sparkle and impact to scenes.

Thanks to the tools available in E7NQ PRO, we've managed to squeeze a pretty decent image out of it, especially with lower quality content. After fine-tuning the white balance of the SDR materials, the colours look much more natural, and what we see on the screen seems closer to the vision the producer intended to present. Additionally, we've improved the brightness characteristics (Gamma), so the TV no longer tends to over-brighten, and everything looks noticeably better than before our intervention.

With HDR materials, we also achieved some improvements, although it's not as rosy here. Yes, the white balance has approached an acceptable level, but the problem lies elsewhere. It's about the EOTF curve, which is how the TV manages brightness and tonality of the image. At first glance, one might think that the biggest issue concerns only the mid-tones, which are overly brightened. However, after more detailed testing and activating the EOTF curve visualisation filters, it becomes clear that the receiver has a tendency to brighten the entire screen. This seems to be a limitation due to the small number of local dimming zones and generally modest brightness management capabilities. Such hardware limitations are simply insurmountable. Nonetheless, after our calibration, the image is noticeably better than at the start. One just needs to be aware that in terms of contrast and brightness management, this model has its limits, which even a good calibration cannot fully overcome.

Despite the television being equipped with a function to reduce posterisation called "Smooth Gradation", we did not notice a significant effect of its operation. Materials subjected to heavy compression, such as YouTube videos, still showed choppy, abrupt tonal transitions, which did not look particularly appealing. While this is due to the material itself and not the television, it would be good if there was a function to mask these issues, similar to those found in competing brands.

Image scaling, which is crucial when playing lower resolution content, we rate as average. Details are not overly blurry, and the image is not "smudged", however, there is noticeable jaggedness on the edges of objects, such as branches, and a halo effect around characters and text. While the television performs quite well, there is still room for improvement, especially in the context of displaying lower quality materials.

When it comes to the tonal transition smoothing function in lower quality materials, the “smooth and gradient image” feature in Hisense E7NQ PRO unfortunately does not impress. At the lowest setting, the change is barely noticeable – it's more of a cosmetic improvement. Switching to “Medium” mode does produce a noticeable effect, but it's still nothing special, and the TV starts to excessively interfere with other elements of the image, which can look unnatural.

Image scaling is also rather average. On the test screen, where a portrait of a model and text are displayed, there are slight frays at the edges, making the overall presentation less smooth and aesthetic than we would expect in this class of device. It's just hard to talk about really effective improvement of lower resolution quality here.

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

Firstly, Full HD resolution on a large TV screen may seem insufficient, affecting image quality. Furthermore, the response time of the panel in this model is not short enough to fully utilise the refresh rate of 240 Hz. As a result, at such a high refresh rate, there is significant overdrive, which causes noticeable smearing and so-called "ghosting" behind moving objects.

It is also worth noting the motion smoothing feature in the TV, which operates up to 120 Hz. This is particularly useful when watching sports and movies, where motion smoothness is crucial. The TV offers stable operation of this feature, minimising the amount of generated artefacts. Motion smoothness can be adjusted using two sliders – one for smoothness in movies and the other for reducing smearing in sports content.

In summary, although the TV Hisense U7KQ offers impressive capabilities in image refresh rates, limitations related to the response time of the panel and appropriate resolution may affect the actual benefits of these features. Nevertheless, the motion smoothing function works very well, enhancing the experience of watching dynamic content.

Thanks to the use of a 144 Hz panel, E7NQ PRO performs exceptionally well with almost any type of content. Whether we're watching fast-paced matches, dynamic games or action films – the fluidity of motion leaves a good impression. When it comes to movies, the manufacturer has equipped the TV with two key tools: “motion blur reduction” and “judder reduction.” Each of these functions can be adjusted on a scale from 1 to 10.

At lower values, the processing is subtle, barely noticeable, and gently smooths motion without ruining the cinematic character of the image. The higher we move up the scale, the more clearly the TV interferes with the presented material, smoothing motion more aggressively, thereby minimising any judders or micro-cuts. Conversely, the highest settings can resemble the so-called “soap opera effect,” which makes the image look overly smooth, slightly losing its cinematic atmosphere. Thanks to this scale, however, we can find a happy medium, adjusting motion fluidity to our own preferences.

The Hisense U7KQ TV supports all the key features for gamers that users of Xbox or PlayStation consoles might expect. These features include support for high refresh rates, low input lag, and a game bar. Generally speaking, most of these features work well, providing a satisfying gaming experience.

However, the VRR (Variable Refresh Rate) technology does not function optimally. When VRR is activated, the TV disables local dimming, which significantly reduces image quality. In VRR mode, there is a lack of good contrast and high brightness in HDR mode, resulting in unsatisfactory image quality. In practice, this means that the VRR mode may be rarely used by gamers due to these limitations.

Additionally, the TV does not support the HGIG (HDR Gaming Interest Group) mode, which is designed to optimise HDR image quality in games. The absence of this mode leads to issues with double tone mapping—once in the TV and again in the console. As a result, the quality of HDR gaming is lower, which can affect the overall gaming experience.

In summary, while the Hisense U7KQ offers many features for gamers, certain key aspects, such as optimal VRR performance and support for HGIG, may not meet the expectations of more demanding users. Nevertheless, the TV still provides good support for most standard gaming features, making it a suitable choice for a wide range of gamers.

If we sometimes like to turn on the console and immerse ourselves in the world of games for long hours, E7NQ PRO can make a really good impression. Thanks to the 144 Hz refresh rate, the gameplay is surprisingly smooth, and support for HDMI 2.1 and VRR ensures that the image doesn't "tear" even during the most dynamic actions. Additionally, there's ALLM, which automatically sets the lowest latency as soon as we switch to the console – so we don’t have to fiddle around in the options ourselves.

A big plus is also the ability to launch games in Dolby Vision, which makes colors and contrast simply look better. Hisense has also included a clear "gamebar," allowing us to continuously monitor the key parameters and change settings without leaving the game. The only thing we might slightly regret is the lack of HGIG support. It may not be a crucial element, but for some gamers, it can matter if they aim for the most faithful reproduction of the creators' vision. Nevertheless, in practice, the E7NQ PRO performs excellently and delivers truly enjoyable gaming experiences.
