LG UT8100 (IPS) vs Hisense U6NQ

Unfortunately, the LG UT8100 television does not meet expectations in the HDR effect category. With a peak brightness of only 300 nits on the luminance chart, it is well below the required value to fully enjoy the HDR effects. In practice, the image resembles SDR quality more than true HDR, which is particularly evident in demanding high-contrast scenes. The coverage of the DCI-P3 colour palette is only 82%, further limiting the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and lacklustre image. For those looking for a television to fully utilise HDR content, the LG UT8100 model proves to be quite disappointing.

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 television delivers consistent performance – in every tested scene, regardless of difficulty, the brightness is around 450 nits. This is a pleasant surprise, as in many models of this class, there are notable 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 expense of black levels, as mentioned in the contrast test paragraph.

The HDR effect on the U6NQ is satisfactory, offering a noticeable "burst" of light in bright moments, although it is worth noting the previously mentioned blooming, which may be visible in more challenging scenes. In terms of colours, the television also performs decently – the coverage of the DCI-P3 palette is 89%, and BT.2020 is 71%. Although these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ serves as a solid choice. Therefore, it presents an interesting proposition as an "entry-level" television for home cinema.

The Filmmaker Mode in LG UT8100, although theoretically the best for watching films, has significant flaws. The biggest problem is the white balance – drops in blue colour cause a noticeable yellowing of the image, evident in both HD and 4K content. These errors are confirmed by the measurement results in the Colour Checker test, which indicate significant deviations in colour reproduction.

Regarding brightness characteristics, both HD and 4K content feature a substantial tonal boost. The gamma curve in both cases remains significantly below the reference value of 2.4, leading to excessive brightening of darker elements of the image. A similar issue is noticeable in the EOTF curve – for 4K content, the television struggles with properly managing brightness, which results in problems with screen brightness. This means that the factory settings of this model require significant adjustments to achieve better image quality.

Hisense U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth noting 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 around 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse with colour reproduction in 4K HDR materials. The dominance of blue shades led to unnatural cool tones on the Colour Checker chart, giving the image a "store-bought" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode loses some of its credibility in this case. Although the factory settings of the tested unit deserve praise, especially in SDR, there were still minor shortcomings that would require correction to fully exploit the capabilities of the television.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically ideal, reference values, which has significantly improved the overall tonal characteristics of HD content. 4K HDR content also looks better, although certain issues are still visible at the extreme ends of the graph, where the curve deviates from perfection. The EOTF curve performs worse, as the television has difficulty maintaining appropriate brightness values. As a result, the image in some scenes may be overly bright or slightly dimmed, which is due to the very design of the device. Nevertheless, the calibration has brought considerable improvement, especially for HD content, where tonal balance and colour reproduction are now at a much higher level.

Although the factory settings of the Filmmaker mode on the Hisense U6NQ were quite good, we decided to carry out a calibration to fully assess the capabilities of this model. Only after such an adjustment 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 most significant change came from correcting the brightness characteristics – the gamma was optimised and no longer causes excessive dimming of the image, which improves its naturalness.

For 4K HDR content, the calibration also produced positive effects. We eliminated the blue dominance issue, resulting in a more balanced and natural image. However, managing brightness in HDR materials remains a more complex matter. The EOTF curve, while having problems with dimming the image in the 10–30% brightness range in laboratory conditions, reveals other shortcomings in real scenes. The television tends to excessively brighten the smallest elements on the screen. As a result, this leads to visible 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 particular model and is often difficult to eliminate.

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

The fluidity of tonal transitions is also correct, although the effect depends on the settings. The update has improved the performance of the smooth gradation function, smoothing transitions better than before, but it has introduced minor issues with detail loss, e.g. on textures.

The image scaling on LG UT8100 performs very well. The image looks decent, without significant issues with edge aliasing. Details are preserved at a satisfactory level, which makes lower resolution materials look truly solid on this television. This allows users to enjoy watching older content without noticeable flaws in quality.

With high-quality materials, such as 4K, tonal transitions on U6NQ look really good – the colours blend nicely, and the image is coherent. Unfortunately, when we move to content in lower resolutions, the television does not offer any additional features that could improve this aspect. An example is the test with the light bulb, where it is clearly visible that the television has a problem with rendering subtle tonal transitions.

However, digital processing performs quite well. The image looks pliable, is pleasantly soft, and free from excessive banding. Moreover, thanks to the sharpness settings, it can be adjusted according to personal preferences – whether towards a softer or sharper image. Overall, although scaling lower quality materials could be better, the television handles image processing effectively.

LG UT8100, equipped with a 60 Hz panel, is particularly suited for those watching films. The television offers the TruMotion system with de-judder effect adjustment, allowing you to customise the smoothness of the image – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on the user's preferences.

Hisense U6NQ offers native 60 Hz refresh rate at 4K resolution, but the manufacturer has added a feature that allows the refresh rate to be increased to 120 Hz, at the cost of reducing the resolution to Full HD. This solution, which we have seen before in TCL televisions, such as the C655 or C655 PRO. This gives the user the choice – higher motion fluidity or full resolution. This is a sensible approach, especially considering that many games on next-generation consoles do not achieve full performance in 4K at 120 Hz.

As for movies, the television is equipped with a motion smoothing feature that allows you to adjust the motion characteristics to your own preferences. This allows for a more cinematic effect or increased fluidity in dynamic scenes. Overall, Hisense U6NQ offers reasonable solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

LG UT8100 offers basic features for gamers, such as ALLM and Game Bar, which makes access to settings easier. The television also supports HGiG, which improves image quality in HDR games. Unfortunately, the lack of support for Dolby Vision and VRR limits the capabilities of the device, as does the 60 Hz panel, which excludes support for 120 Hz resolution. This model is more suitable for less demanding gaming applications.

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