LG UT8100 (IPS) vs Hisense E7Q / E79Q

The LG UT8100 television unfortunately does not meet expectations in the HDR effect category. A peak brightness of only 300 nits on the luminance chart is well below the required value to fully enjoy 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%, which further limits the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and washed-out image. For those looking for a television to fully utilise HDR content, the LG UT8100 model turns out to be quite disappointing.

Hisense E7Q / E79Q is a mid-brightness TV, with a peak luminance level of around 350-380 nits. This is the absolute minimum that allows viewing HDR content in a way that's close to the creators' intentions, though without a distinct "wow" effect. The results of synthetic tests on white test patterns were confirmed in practice – in movie scenes, the bright parts of the image are stable and fairly even, but it's hard to talk about a true "burst of light" here. In everyday use, such as when watching Netflix or YouTube, the HDR effect is acceptable and is more than sufficient for most users. However, it must be said clearly – this is not the level of top-end screens, and one shouldn't expect that at this price. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to score quite a few points: it's a QLED panel of the PFS LED type, using an additional phosphor layer that improves colour reproduction. The measured range of the DCI-P3 colour gamut is around 92%, which means that the colours in most scenes are vibrant, well-saturated, and pleasing to the eye, especially for this price bracket.

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

In terms of brightness characteristics, both HD and 4K content exhibit a large tonal boost. The gamma curve in both cases remains well below the reference value of 2.4, which leads to excessive brightening of darker elements of the image. A similar problem is evident in the EOTF curve – in the case of 4K content, the TV struggles to manage brightness correctly, resulting in issues with screen brightness. This means the factory settings of this model require significant adjustment to achieve better picture quality.

In Filmmaker mode, the Hisense E7Q / E79Q television really managed to impress. After the first measurements, it turned out that the white balance was quite well tuned, with the only minor deviation being a slight tendency towards a purple hue, which we mentioned earlier. However, this did not significantly impact the overall character of the image – it remained cohesive and pleasant to view. A much bigger issue was the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening contrast and taking away depth. Gamma values could drop from the reference 2.4 down to around 1.9, making the image look as though it was covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically perfect, reference values, which has significantly improved the overall tonal characteristics in HD content. 4K HDR content also looks better, although some issues are still visible at the extreme ends of the graph, where the curve deviates from the ideal. The EOTF curve performs worse since the TV struggles to maintain the correct brightness values. As a result, the image in some scenes may be too bright or slightly dim, which stems from the device’s design. Nevertheless, the calibration brought significant improvement, particularly for HD content, where the tonal balance and colour reproduction are now at a much higher level.

The biggest beneficiary of calibration in the case of the Hisense E7Q / E79Q was undoubtedly the SDR mode. It managed to achieve almost perfect image quality – most of the errors in the Color Checker test dropped below a value of 3, and often even 2, which is a remarkable result for this class of equipment. The biggest improvement came from aligning the brightness characteristic (gamma), which made the image no longer look blown out and regained natural depth. In HDR content, it was also possible to improve the colours and eliminate the purple tint that we mentioned earlier, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite strongly, overexposing some colours. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor issues with excessive brightening. Despite this flaw and the construction limitations that arise with HDR content, the Hisense E7Q / E79Q gained quite a bit after calibration. In everyday use, the television presents a coherent, natural, and pleasant-to-the-eye image, and the difference compared to the factory settings is indeed huge.

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

Image scaling on LG UT8100 performs very well. The image presents itself decently, with no major issues regarding edge aliasing. Details are preserved at a satisfactory level, making materials of lower resolution look really solid on this television. As a result, users can enjoy watching older content without any noticeable defects in quality.

In the case of Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest points of this television. It is evident that the manufacturer has opted for simplicity rather than advanced image processing algorithms. The television does not offer any features that smooth tonal transitions or systems that enhance image clarity, which makes lower resolution materials look quite raw. Subtle compression edges can be seen on the screen, which better processors in other models can effectively hide.

During the testing of HD materials, we noticed that the E7Q tries to artificially boost detail, which sometimes works and other times has the opposite effect – the image becomes soft, slightly blurred, and at times even "watery." There is no aggressive sharpening that ruins naturalness, but there is also a lack of finesse in detail integration that better image processors provide.

LG UT8100, equipped with a 60 Hz panel, is particularly suited for those watching movies. The television offers the TruMotion system with a de-judder effect adjustment, which allows users to tailor the smoothness of the picture – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on user preferences.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so sports fans in 4K may feel a slight disappointment – you simply won’t see such smooth images here as in more expensive models with higher refresh rates. Fortunately, when it comes to movies, the situation is much better. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to adjust the picture to their own preferences – more cinematic with visible frames or smoother, in a theatrical style.

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

Hisense E7Q / E79Q is a really good TV for gamers, even though it doesn’t support 4K signal at 120 Hz. However, the manufacturer has included a set of features that until recently could only be found in more expensive models. There's ALLM, which is auto-switching to low latency mode, allowing the TV to activate game mode with very low input lag automatically. We also have VRR, working up to 60 Hz – while this may not look impressive on paper, in practice it is fully sufficient, as most console games don’t exceed this limit anyway. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this level, you can change picture modes, turn on a frame counter, or even… an on-screen crosshair – in the Vidaa system amusingly called a “target point,” which is the result of a clumsy translation from the Chinese manufacturer.

Special praise should go to the ability to play in 1080p at 120 Hz, which significantly improves the fluidity and responsiveness of the image. This means that if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy much smoother motion. Despite the lack of 4K@120Hz, the Hisense E7Q / E79Q really performs well as a gaming TV – especially for those who aren’t looking for perfection but a solid and fast screen for everyday gaming.
