Hisense U7KQ vs LG QNED86A / QNED85A / QNED87A

Describing the HDR effect in the hundred-inch model Hisense U7KQ is not straightforward and requires broader context. As can be observed, the results are highly varied, depending on the type of scene and the intensity of the bright effects the television is meant to reproduce. In bright scenes, the device achieves over a thousand nits of brightness, which translates to vivid and realistic images – these are exactly the effects we expect from equipment of this class. Unfortunately, the situation deteriorates in darker scenes. In mixed shots, such as those in the film "Gemini Man," the television still offers good brightness at a level of 700 nits, allowing for enjoyment of high-quality content. However, problems arise in very dark scenes, where small light sources play a central role. The television does not fully utilise its capabilities here to avoid degrading the black level in adjacent areas. As a result, there is no spectacular "WOW" effect, and such frames often do not seem as if they are being produced in HDR technology.

Against a backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect perform much better. This is a television that can achieve around 700 nits under the best conditions, so in terms of luminance alone, there is nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape look clear and can make an impression. Interestingly, even in more challenging moments with small, contrasting elements on the screen, the television manages well with their backlighting, and the details are quite visible. The problem arises when there are many dark tones. The lack of effective local dimming causes the black to practically disappear, and instead, we get a grey haze spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic character. In bright animations or colourful family films, this will not be a problem, as vibrant colours and bright light dominate. But in horrors or productions set in darkness, these limitations are very strongly felt. As a comfort, it is worth adding that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of a wide colour gamut. Both the DCI-P3 palette and the broader BT.2020 perform really well here. This makes the colours in HDR films saturated, juicy, and with the appropriate depth – even if the black itself disappoints, the colours can save the viewing experience and make the image look attractive.

The best factory mode we measured was 'Filmmaker'. Despite this, its characteristics left a wide scope for comment. Let us take a look at the gamma chart, which is responsible for the depth and contrast of the image. First, we will pay attention to the orange line running through the middle of the chart, starting at point 2.4. This is the reference value of the REC.709 standard. Now, let us look at the measured value, which is marked by a white, connected multi-point. Such a significant drop in gamma to a value of 2.0 indicates a considerable decrease in contrast, resulting in an image lacking proper depth, and one could observe the so-called 'milk' effect. The next thing we tested was the white balance. Though unassuming, if poorly configured, it can alter the entire character of the image. At the beginning, the chart was progressing quite well, but as we went further, it 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 adjustment, we were able to significantly improve the display's performance in SDR materials, as evidenced by low deltaE errors and very well-rendered gamma and white balance.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most faithful picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable was the poorly tuned white balance – there was a lack of blue, causing the overall image to take on a slightly yellowish, and at times even orange hue. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – specifically, local dimming that only works along the edges of the screen – the QNED86A tends to oversaturate entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of clear depth and contrast, we get something akin to “boosted brightness,” which can strain the eyes over time.

In SDR mode, after calibration, the television Hisense 100U7KQ looks excellent. There is nothing to fault in terms of colour reproduction - both pastel and strongly 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 rendered.

In HDR mode, however, there is a noticeable boost in bright tones. The television attempts to beautify the picture, which can lead to an artificial brightening. This phenomenon becomes even more evident in real scenes, where bright parts of the image may be excessively enhanced. Although the colours in HDR are generally good, they are intentionally boosted too much by the manufacturer, which can affect their naturalness.

This approach by the manufacturer to displaying images in HDR mode may not appeal to everyone, especially those who value authenticity and fidelity to original colours. However, for those who prefer more dynamic and vivid images, such an emphasis on bright tones can be an attractive solution, adding extra sparkle and impact to the scenes.

What has been saved in the QNED86A6A is undoubtedly the colours. After calibration, the white balance was set with great precision, ensuring that deviations on the Colour Checker palette mostly did not exceed the visibility threshold for the human eye. In other words – the hues finally looked natural, without the strange yellow or orange tones that previously spoiled the perception. Unfortunately, even the best calibration cannot circumvent the structural limitations. The already very modest number of local dimming zones and their unfortunate placement mean that the analysis of the EOTF curve in films still showed clear over-brightening of scenes. The picture tended to flatten, lacking cinematic depth. Fortunately, this effect is not so noticeable in older productions or in SDR content. There, the calibration truly makes a difference and allows one to harness the QNED so that the image can be appealing. However, the specifics of this construction – especially the issues with contrast – cannot be completely bypassed.

Although the television is equipped with a feature for reducing posterisation called "Smooth Gradation," we did not notice a significant effect of its operation. Materials subjected to heavy compression, such as YouTube videos, still exhibited choppy, distinct tonal transitions, which did not look particularly favourable. While this is due to the material itself rather than the television, it would be good if there were a feature to mask these problems, similar to those found in displays from competing brands.

The image scaling, which is crucial when playing lower resolution content, is rated as average. Details are not overly blurred, and the image is not "smudged"; however, there is visible jaggedness on the edges of objects, such as branches, and a halo effect around figures and text. Although the television performs quite well, there is still room for improvement, especially in the context of displaying lower quality materials.

If someone is worried about potential "steps" when blending colours, there is a simple way in the QNED86A to address this. Just activate the feature called Smooth Gradation and set it to a medium level. Then the television really smooths out all those unwanted transitions quite well – especially in older productions – and it does so in a way that film grain doesn't disappear, nor do strange artefacts appear. In other words, it can be used without concern.

The upscaling itself also performs quite well. Of course, there are no miracles here – with lower quality sources, you can notice characteristic ringing. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "soft" image, it can be quickly adjusted to personal taste.

The television correctly accepts a 4K signal up to 144 Hz, allowing for very smooth images to be displayed in high resolution. When the resolution is limited to Full HD, the television is capable of handling 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.

First of all, the Full HD resolution on a large television screen may seem insufficient, which affects 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, significant overdrive occurs, causing noticeable smearing and so-called "ghosting" behind moving objects.

It is also worth noting the motion smoothing function in the television, which operates up to 120 Hz. This is especially useful when watching sports and films, where smooth motion is crucial. The television provides stable operation of this function, minimising the amount of generated artifacts. Motion smoothness can be adjusted using two sliders – one for film smoothness and the other for reducing smearing in sports content.

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

The QNED86A is equipped with a panel boasting a refresh rate of 120 Hz, so it can be said from the outset that it is suitable for both sports and gaming. And indeed, it is – the image appears smooth, and motion blur is not particularly intrusive. IPS panels have always had some issues with this, and here too, slight blurring can sometimes be noticed, especially in very dynamic scenes, but it is not something that ruins the viewing of a match or a fast-paced game. For cinema and sports fans, LG has included the traditional TruMotion smoothness enhancer. In the menu, we have two sliders – one for movies (De-Judder) and the other for sports (De-Blur). The first adds missing frames and can be adjusted to modify the character of motion – from raw, cinematic to a smoother, more ‘theatrical’ look. The second improves sharpness during dynamic actions, so it's worth turning it up a bit if you watch a lot of sports.

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

However, the VRR (Variable Refresh Rate) technology does not function optimally. When VRR is activated, the television disables the local dimming feature, 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 television 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 television and once in the console. As a result, the quality of HDR games is lower, which may affect the overall gaming experience.

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

In terms of gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, Xbox Series X, or a powerful PC, everything will run in full 4K at 120 Hz with support for all functions. This is a significant advantage, as some competitors still only offer two such ports, which can be troublesome with multiple devices. It also includes VRR, or variable refresh rate, which eliminates screen tearing, as well as ALLM, which automatically activates game mode when the console is turned on. Dolby Vision Gaming is also included, along with proper implementation of the HGiG format, so titles that support these formats look more vivid and detailed. On top of all this, there is the Game Optimizer – a sort of control centre for gamers. From this interface, you can view picture parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your personal preferences. The LG QNED86A6A essentially has everything one could expect from a modern gaming television.
