LG OLED G4 vs Hisense U7NQ

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

The Hisense U7NQ 65 television demonstrated significant capabilities on the luminance chart, exceeding the 1000-nit barrier and achieving very high brightness results without issue in the first, third, and fifth test scenes. However, as before, in the second and fourth test scenes, for example from the film Sicario 2, there are significant problems with maintaining brightness, and the results around 200 nits are very disappointing. Despite a large number of dimming zones, the algorithm in the television responsible for controlling these zones is unable to react appropriately — in this case, it significantly dims small elements like the moon or the light from a helicopter. The bright light that should blind us is too dim to be called an HDR effect. Nevertheless, it is worth praising the television for its high coverage of the DCI-P3 colour gamut at 96%, which allows it to accurately reproduce most film scenes.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

The Chinese manufacturer offers various picture settings with its televisions, but the best mode in this model is undoubtedly the Filmmaker Mode. Despite its name, this mode has its issues: the white balance, although roughly correct, is characterized by a strong dominance of warm tones due to the kick of red colour, both in 4K and HD materials. The Colour Checker test confirms these errors — deviations in samples are visible in inappropriate shades. As for the brightness characteristics, the gamma responsible for HD materials shows values below 2.4, leading to some brightening of the screen. Meanwhile, the EOTF curve shows the television's problems with displaying small light elements, as confirmed by the previously described paragraphs.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

Hisense televisions offer many tools for image correction, allowing users to adjust settings to their preferences. Therefore, we decided to utilize these capabilities to bring the image quality closer to reference standards. In the case of white balance, we managed to eliminate the dominance of red, resulting in more neutral colours, which allowed for a more realistic image in both 4K and HD materials. A similar improvement was noticed in the brightness characteristics. Gamma, which previously led to excessive screen brightness, was corrected, contributing to better detail representation in the darker areas of the image while maintaining a natural tonal balance.

However, the biggest challenge was the calibration of the EOTF curve, which is responsible for brightness in 4K materials. At first glance, the EOTF value appeared almost perfect, but detailed tests showed a slightly different outcome. Upon closer inspection—especially using the filter on the right side of the EOTF chart—we noticed how the television manipulated 4K film materials, often significantly boosting brightness. This effect was particularly noticeable in scenes from films such as Pan and Billy Lynn, where the television attempted to artificially increase the brightness of elements, affecting their naturalness. Despite these imperfections, the calibration yielded positive results, especially in terms of tonal improvement. For most users, the final effect should be satisfactory, especially if they aim to bring image quality closer to professional reference standards.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 0.

The LG G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

Hisense U7NQ has a refresh rate of 144 Hz, which definitely contributes to smooth motion. For movie enthusiasts, there are two features available: judder reduction and motion blur reduction. The judder reduction feature minimizes the effect of so-called judder, which is the unpleasant stuttering of the image, particularly noticeable at lower frame rates. On the other hand, motion blur reduction helps sharpen fast-moving objects, which is useful when watching dynamic action scenes.

As for motion blur, the TV has a decent response time, so excessive blurriness is not visible, except in specific situations, such as the test with the little green alien on a dark background. In such cases, slight artifacts may appear, but overall, the TV handles dynamic images well, providing satisfactory motion quality.

The LG G4 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

Hisense U7NQ offers everything a gamer might need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, providing an incredibly smooth image, especially in dynamic action games. The VRR (Variable Refresh Rate) feature ensures that the image adapts to changing frames per second, eliminating stuttering and tearing. Additionally, there is an ALLM (Auto Low Latency Mode) feature that automatically switches the TV to game mode, minimizing input lag.

The TV also supports Dolby Vision, which is particularly important for gamers who value high contrast and vivid colors in games that support this format. The Hisense U7NQ also has a Game Bar feature that allows quick access to essential settings during gameplay, as well as support for G-Sync technology, which further reduces image tearing.

Unfortunately, despite the wide range of features, support for the most popular HDR format in gaming — HGiG — is lacking. This may be disappointing for gamers who expect optimal detail representation in HDR scenes. Nevertheless, the remaining features make the Hisense U7NQ a solid choice for any console gaming enthusiast.
