Hisense U8NQ vs LG 55 B4

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 brightness results in HDR materials LG B4 are very good. It is true that none of them exceed 1000 nits, although the luminance stability is excellent and looks practically the same in every scenario. The only moment where the tested television performs worse is the last scene, although this should not come as a surprise. Large frames filled with a lot of white have always been, and will likely continue to be, somewhat of a weakness for OLED televisions. However, the combination of perfect contrast, black levels, and brightness in the LG B4 allows for a full spectrum of the HDR effect. Additionally, the incredibly high coverage of the DCI-P3 colour gamut, which reached 99%, deserves recognition. As a result, colours look incredibly vibrant and stunning.

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 prepared by the manufacturer is "Filmmaker," and we used it throughout the entire testing procedure. We must admit that the unit we received straight out of the box had quite decent colour reproduction. The biggest issue in both SDR and HDR content turned out to be white balance. In the former, there was a strong dominance of red, resulting in a noticeable yellow tint in the displayed image, particularly evident on skin tones and whites. In high-quality materials, this colour was also pronounced, but due to a lack of blue, there were also signs of green visible. Besides these shortcomings, we also encountered issues with greyscale and the colours themselves.

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.

LG B4 has been providing very advanced calibration tools in its TVs for years. We can even say that as the only manufacturer on the market, it allows for such deep intervention in image adjustment. Thanks to these, we were able to calibrate the device so well. The evidence of this is the extremely low deltaE errors, which can be said to stand at a reference level. Both SDR and HDR materials now look exactly as the film director intended. It is no coincidence that TVs of this brand are most often used as preview screens for various graphic or post-production studios.

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.

In this paragraph, we will take another look at the tonal transition smoothing feature, but we will also check how the TV handles lower quality material. As we have managed to check, the setting responsible for smooth gradation works quite effectively, although it has its weaker moments. While the feature works well with SDR content, it becomes less useful with HDR content. Even at the lowest of options, it blurs essential details, so we advise against using it.

The image scaling on LG B4 is rated fairly moderately positively. Although there is no edge splitting, the image itself is naturally "soft". We can change this by adjusting the sharpness slider.

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 B4 is 120 Hz. This is the absolute minimum for those who require high image smoothness. The manufacturer has implemented a multi-level motion smoother called "TruMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and stuttering (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, so everyone can find their sweet spot.

The LG OLED B4 panel features an average response time of 0.1 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable for LCD TVs, which have response times of even several milliseconds. This can be clearly seen in images from the "UFO Test", showing no trace of blur trailing 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.

The LG B4 television is equipped with four full-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All functions corresponding to this standard activated without any issues, and throughout the entire testing procedure, they caused no problems. The combination of such extensive functionality and low input lags leads us to say that the tested television is truly designed for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both a properly implemented HGIG mode and gameplay in Dolby Vision with low latency. Such a tandem will surely attract the attention of all passionate gamers for whom quality is the most important.

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 enables image adjustments for individuals with visual impairments, which is an extremely nice touch. Another important piece of information is that when the VRR technology is turned on, we will not experience a drop in contrast. This is, of course, due to the construction of the panel and the lack of conventional backlighting. However, it is normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and the television.

In summary: The LG B4, like all OLEDs from the manufacturer equipped with 120Hz panels and HDMI 2.1 ports, creates a harmonious whole with the console. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, the B4 will be the ideal choice.
