Hisense U8NQ vs LG OLED C4

Hisense U8NQ demonstrates its capabilities in HDR, achieving a luminance score on the chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television showcased very high brightness, which is impressive and allows you to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2," the television encounters issues maintaining brightness, resulting in disappointing scores around 250 nits. Although the large number of dimming zones should theoretically help, the algorithm responsible for their control does not always work perfectly—bright, small elements like the moon or helicopter lights are too dimmed, which takes away from the typical HDR effect. Instead of blinding brilliance, we receive a more subdued light that does not convey the full potential of HDR. Nevertheless, the television deserves commendation for its very good coverage of the DCI-P3 colour gamut at 97%. This makes colours vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode present in this model. Despite its accuracy, it has significant errors in reproducing the reference image, which we will describe now. In the case of HD content, the white balance shows a distinct dominance of red, causing the image to appear overly pinkish and warm. In the comparison photo below, you can see how this effect impacts the presentation of content. The brightness characteristic also leaves much to be desired—a too low gamma causes the screen to be excessively brightened, and blacks appear washed out, making the overall image seem cooler than it should be.

For 4K HDR content, the problem is the opposite—the white balance shows too much dominance of blue, making the image take on an artificial quality and seem unnaturally sharp. All these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly shows how the colours deviate from the correct patterns.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

The white balance for both 4K and HD content has been heavily adjusted, significantly improving the image quality. While some errors are still visible, they are not large enough to greatly affect the perception of the image. A notable improvement can also be seen in the gamma brightness characteristic — the image is no longer excessively bright, resulting in more natural blacks and better contrast.

However, like with many other Hisense models, there are noticeable issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although it may seem correct at first glance, when the filter is applied to the "EOTF in films" chart, it is evident that the TV is somewhat "playing around" with 4K content. It is clear that the EOTF curve is significantly below the reference level, leading to an overall dimming of the image compared to the reference. We noticed this effect in previously tested scenes from the films "Pan" and "Billy Lynn." While it is not a serious issue, it is worth paying attention to. It could be significant for those seeking a display with the most faithful image reproduction. Despite this error, the image will be more enjoyable for most. Colours are represented better, and the overall image quality is significantly improved.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

In the context of smoothing tonal transitions, the Hisense U8NQ unfortunately struggles. The "Smooth and Gradient Picture" feature does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with a lot of subtle tonal transitions.

As for the digital processing, or so-called upscaling, the scene with the model is rendered correctly — her outline is clear, without significant cropping. Similarly, thin lines, like tree branches, have slight jaggedness, but the overall image looks plastically and softly, providing a good impression. Unfortunately, there is also an issue with so-called overscan, which results in cropping of the image at the edges. This can be annoying when watching content such as news, where the bottom information bars may be partially invisible.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The TV will also satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" enhancer that allows users to control the smoothness of the image — you can choose whether you prefer a more "framey" picture or a smoother, cinematic effect. This provides great flexibility in adjusting the motion quality to individual viewer preferences.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

Hisense U8NQ offers everything a player might need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an incredibly smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature allows the image to adjust to variable frames per second, eliminating stuttering and tearing, translating to exceptionally smooth gaming. Additionally, the television is equipped with the ALLM (auto low latency mode) feature, which automatically switches the TV to game mode, minimising input lag. This means players can enjoy responsive gameplay without needing to manually adjust settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high image quality, high contrast, and deep colours in games that support this format. The television also features a "Game Bar" — a function that allows quick access to essential settings during gameplay, significantly enhancing user convenience.

However, it is worth noting that despite its rich set of features, the Hisense U8NQ does not offer support for the HGiG standard, which is a popular HDR format in gaming. This may be disappointing for players expecting optimal detail reproduction in HDR scenes. Nonetheless, the other features of the television make the Hisense U8NQ a solid choice for console gaming enthusiasts, offering fluidity, high contrast, and user convenience.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.
