Hisense U7KQ vs Hisense U7Q

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.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good outcome when it comes to brightness and overall HDR quality. Unfortunately, we have to disappoint you a bit here.

The U7Q is quite a bright television – under the best conditions, it can reach around 800 nits, which indeed impresses in some scenes, especially in scenes like those from the movie The Meg. Bright segments can shine, and the HDR effect is noticeable. The problem arises when very small, bright elements appear on a dark background – for example, in Sicario 2 or in the second scene from Life of Pi. At such moments, the dimming algorithms operate too aggressively. Yes, the blacks look great at that point, but the brightest spots can almost completely disappear, causing the HDR effect to vanish and details to be barely visible. That’s just the charm of this technology in this price segment.

As a consolation, it is worth mentioning that the U7Q is marketed as a QLED (in practice, a PFS layer is used, which operates very similarly), and it can indeed display a wide colour gamut – a DCI-P3 coverage of around 94% is a very good result for this class.

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.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This mode is supposed to provide the most "cinematic" experience that aligns with the creators' intentions – straight out of the box. Unfortunately… even this professionally sounding name doesn’t guarantee a perfect image.

In our unit, the problem lay in the poorly set white balance. In both HD and 4K content, the image had too much blue and red, resulting in a slightly pinkish hue on the screen. It didn’t look terrible, but it was noticeable – especially in bright scenes and on white backgrounds. That alone could have been forgiven, but the biggest issue is managing brightness in HDR content. The EOTF curve from the measurements confirms what we saw earlier during scene tests: the television can overly dim the smallest bright elements, causing them to nearly disappear, or conversely – excessively brighten the brightest parts, which affects the naturalness of the image.

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 specialist tools, we managed to correct the colour quality in SDR content to almost perfection. In materials with lower dynamics, delta E errors dropped below 0.5, which can be considered an almost reference result. The picture on television, YouTube, or classic Full HD looks really good after calibration. Well then – but where was it not so easy to improve the image? Primarily it concerns HDR quality content. Although we managed to somewhat "tame" the white balance and eliminate pink tints in most scenes, unfortunately, we did not have full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of overly strong dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of content is much better, one must reckon that the U7Q will always have something to say at the end with "but".

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.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q has been equipped with a feature called “Smooth and Gradient Image,” but unfortunately… it works very poorly. In the “Low” option, the effects are practically unnoticeable, and other settings smooth out the details but don’t improve tonal transitions. The only positive thing is that the feature doesn’t interfere with the film grain, so it doesn’t ruin the natural structure of the image.

Fortunately, content scaling performs quite well. The image is not overly sharpened, there is no artificial clarity – and while it’s known that this isn’t the level of high-end TVs, the U7Q has no problem displaying really old content in a completely acceptable manner.

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.

U7Q is a truly fast TV, much like its more powerful version “PRO”. At 4K resolution, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it’s worth appreciating – it’s a rare feature in this price segment. Right from the start, it’s clear that the U7Q has been designed with dynamic content in mind, such as games or sports. In films, we’re not left “out in the cold” either – the U7Q offers an “Ultra Motion Smoothness” feature, where with two sliders, you can adjust whether you want a smoother, theatrical picture, or something closer to cinematic style with a visible frame. It’s good that, like most manufacturers, we have a choice here and can customise it 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.

The Hisense U7Q is a TV designed with gamers in mind – and you can see that straight away with its gaming capabilities. It has practically everything you could wish for: Variable Refresh Rate (VRR) – check, Auto Low Latency Mode (ALLM) – check, and high refresh rates of up to 240 Hz in Full HD, along with support for various resolutions, not just 4K. It’s truly an impressive set of features that makes the U7Q perform well with both fast-paced shooters on consoles and more demanding titles on PC. Of course – like most Hisense models – it lacks a proper implementation of the HGiG feature. It’s a shame because HGiG allows the console's brightness to be adjusted to the specific TV, which in practice makes it easier to display HDR games according to the creators' intentions. Without this, you just have to deal with some limitations in the final HDR image in games.
