LG QNED87T6B vs Hisense U6NQ

LG QNED87T6B delivers truly decent visual experiences when it comes to HDR. During our tests on test patterns, the television achieved brightness close to 500 nits, which is a satisfactory result and allows for good visibility of details in high dynamic range scenes. Support for basic HDR formats such as HDR10 and HLG ensures proper image quality. Unfortunately, the television does not support more advanced standards such as Dolby Vision or HDR10+, which are particularly important at this screen brightness. The lack of support for dynamic metadata means that in certain scenes, the television may struggle to fully reproduce details, especially in very bright areas – this is precisely when dynamic metadata could significantly improve image quality. Nevertheless, it is worth noting the excellent coverage of the wide DCI-P3 colour gamut, reaching as much as 96.4%. As a result, the colours displayed by the QNED87T6B model are more vivid and natural, enhancing the quality of 4K content viewed with a wide colour palette.

Hisense U6NQ offers a stable HDR effect, which is a rarity in TVs with local dimming. On most streaming platforms, in films and series recorded in 4K, the TV delivers consistent performance – in every tested scene, regardless of difficulty level, brightness is around 450 nits. This is a pleasant surprise, as many models in this class exhibit distinct differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, the Hisense U6NQ prioritises maintaining higher brightness, which comes at the cost of blacks, as noted in the paragraph about the contrast test.

The HDR effect on the U6NQ is satisfying, offering a noticeable 'punch' of light in bright moments, although it's worth remembering the aforementioned blooming, which can be visible in challenging scenes. In terms of colour, the TV also performs adequately – the coverage of the DCI-P3 colour gamut is 89%, while BT.2020 is 71%. While these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ is a solid choice. As such, it presents an interesting option as an 'entry-level' TV for home cinema.

The colour accuracy in the LG QNED, even in Filmmaker Mode, which is the best factory setting, is not without its flaws. The main issue is white balance – we noticed that the level of blue on the graph tends to drop. This results in a shift in colours towards yellow, making the image have a warmer tone than it should. This deviation affects the naturalness of colour reproduction, especially in scenes with a white or neutral background. The Color Checker test confirmed that some colours are distorted and deviate from reality. Such distortion can make film scenes appear less realistic, and details are presented in incorrect colours, negatively impacting the overall image quality.

Regarding contrast, the gamma graph analysis showed significant drops, while the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in some scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural drop was noted at the beginning. This phenomenon can result in less accuracy in reproducing dark scenes, which in turn affects the overall image quality. The television may not convey full black depth, causing more demanding scenes to lose realism and detail. As a result, viewers may notice that details in the darker parts of the image become less distinct.

Hisense U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth remembering that differences between individual units can be noticeable. The model we tested was pleasantly surprising, especially with HD content in SDR quality. The white balance was correct here, and errors in the range of 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse in reproducing colours with 4K HDR material. The dominance of blue tones led to unnatural cool shades on the Colour Checker chart, giving the image a "store" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode in this case loses some of its credibility. Although the factory settings of the tested unit deserve praise, particularly in SDR, there were still minor shortcomings that would require adjustments to fully utilise the television's capabilities.

After calibration, the colours in SDR content look very good. The improved white balance translates to natural and harmonious shades in various scenes. Thanks to precise gamma tuning, details in shadows and bright areas of the image are accurately reproduced. The television performs excellently in everyday use, offering vibrant, well-balanced images and solid colour quality in HD. The biggest beneficiary here is also contrast. The gamma graph has been stripped of significant errors, giving the television a new dimension.

As for the white balance in 4K HDR, it has also been significantly improved. However, some errors still appear at the end of the graph. This may be due to the television's overly aggressive local dimming, which in some scenes affects the inaccurate reproduction of colours. It's difficult to talk about an improvement in brightness represented by the EOTF curve. The television, due to its construction limitations, has some drawbacks, and we can't overlook them. The Color Checker test confirms the issue with colour saturation – even though the television offers a wide colour palette, it fails to fully convey the director's intent.

Despite these shortcomings, the overall picture quality after calibration is significantly better than before. Adjustments in white balance and gamma tuning make the images more vivid and the colours closer to reality.

Although the factory settings of the Filmmaker mode on Hisense U6NQ were quite good, we decided to undertake calibration to fully assess the capabilities of this model. Only after such a procedure can one see how the television performs under ideal conditions. In the case of SDR content, which was already at a high level, we managed to further improve the white balance. However, the biggest change came from adjusting the brightness characteristics – gamma was optimised and no longer causes excessive darkening of the image, which improves its naturalness.

For 4K HDR content, calibration also yielded positive results. We eliminated the issue of blue dominance, which resulted in a more balanced and natural image. However, managing brightness in HDR materials remains a more complicated issue. The EOTF curve, although it had problems with image darkening in the 10–30% brightness range under laboratory conditions, reveals other shortcomings in real scenes. The television tends to overly brighten the smallest elements on the screen. As a result, this leads to noticeable halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, arises from the technological limitations of the model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings performed decently, calibration allowed us to achieve an even better effect – minor adjustments resulted in a more balanced image, particularly in HDR content. For users seeking the highest quality picture, calibration will be a beneficial step.

When it comes to lower quality materials, the gradation looks really good. The feature called "Smooth Gradation" effectively smooths out the most problematic parts of the image, while not negatively affecting the film grain. For the best effect, it’s worth setting it to a low level. This solution significantly improves the quality of the displayed content, making the viewing of lower resolution materials more enjoyable and smoother.

In terms of digital processing, the image is displayed without cropping, known as overscan. Although slight fraying of the branches can be noticed against the model's background, everything looks very good. Users should be satisfied with the image quality when watching low-quality materials like standard television. The TV handles this task exceptionally well, providing a satisfying visual experience, even with lower quality content.

With high-quality materials like 4K, tonal transitions on U6NQ look really good – colours blend nicely and the image is consistent. Unfortunately, when we switch to lower resolution content, the television doesn’t offer any extra features that could improve this aspect. An example is the test with the light bulb, where it’s clearly visible that the television struggles with reproducing subtle tonal transitions.

On the other hand, digital processing performs quite well. The image looks lively, is pleasantly soft, and free from excessive artifacts. Moreover, thanks to the sharpness settings, it can be tailored to individual preferences – whether towards a softer or sharper image. Overall, while upscaling lower quality materials could be better, the television handles image processing well.

The television provides decent smoothness when watching movies, thanks to the “Tru Motion” feature, which allows adjustment of motion smoothing from 0 to 10. De-Judder regulates motion smoothness, while De-Blur adjusts motion sharpness. Users have the option to choose between a traditional cinematic effect with subtle juddering motion (lower settings) and a smoother, theatrical image. Although the latter deviates slightly from the cinematic standard, it may be appealing to many viewers.

As for gamers and sports fans, the LG QNED87 television with a 120Hz panel will surely not disappoint. And with the use of an IPS panel, the response time is typically better than that of VA panels available at a similar price. This ensures smoother gameplay and dynamic experiences when watching sports events.

Hisense U6NQ offers native refresh rates of 60 Hz at a 4K resolution, but the manufacturer has added a feature that allows for an increase in refresh rate to 120 Hz, at the cost of reducing the resolution to Full HD. This is a solution we have previously seen in TCL televisions, such as C655 or C655 PRO. This gives the user the option – higher motion fluidity or full resolution. This makes sense, especially considering that many new generation console games do not achieve full performance in 4K at 120 Hz.

When it comes to movies, the television is equipped with a motion smoother feature, which allows you to adjust the motion characteristics to your own preferences. This enables a more cinematic effect or increases fluidity in dynamic scenes. Overall, Hisense U6NQ offers sensible solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

LG QNED offers a range of features that make it an excellent choice for gamers looking for a high-performance television. The TV is equipped with four HDMI 2.1 ports, allowing connection to the latest consoles like PlayStation 5 and Xbox Series X, utilising full functionality including Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). Thanks to the Game Bar feature, gamers can quickly and easily manage all game settings without needing to navigate complex menus. Parameters such as VRR, ALLM, Multi View, and frame rate monitoring can be adjusted. The TV also supports G-Sync and FreeSync technologies, which is particularly important for owners of Nvidia and AMD graphics cards. G-Sync and FreeSync synchronise the TV's refresh rate with the graphics card. The 120Hz panel guarantees incredible motion smoothness and image clarity. Combined with the Black Frame Insertion (BFI) feature, which is available at 60Hz and 120Hz, gamers can enjoy an even sharper and smoother picture. LG QNED87 is a television that meets the expectations of even the most demanding gamers, offering modern technologies and features that significantly enhance comfort and satisfaction during gaming.

Hisense U6NQ gives the option to choose between 4K at 60 Hz and Full HD with 120 Hz refresh rate. This solution may appeal to gamers who want to decide what is more important to them – higher resolution or smoothness. The TV supports features like ALLM and VRR, which help in providing smoother gameplay. A nice addition is the GameBar – an easy-to-use panel that allows quick adjustments to picture settings and checking statistics. We also find the Dolby Vision Game mode here, which operates with low input lag, a big plus for console enthusiasts. Unfortunately, it lacks HGiG, which could further improve HDR quality in games. Nevertheless, the Hisense U6NQ performs quite well as a gaming TV, especially for those who play occasionally and do not require the highest refresh rate in 4K. It is a solid choice for less demanding users.
