Our verdict

6.0

Overall rating

LG UT8100 is a model that does not try to pretend to be more than it is. Simple, functional, and well-suited for everyday use. Its biggest advantage is the WebOS system – intuitive, fast, and rich in applications. With such a backend, using Netflix or YouTube is hassle-free, and navigating the menu takes just a moment. The Magic remote adds even more convenience, as it works somewhat like a mouse – just point at the screen and click what we want. Voice control in Polish? It works flawlessly, and we can confidently say it is the best when it comes to our native language. One of the more interesting features is the ability to record to USB. It's a minor detail, but it can come in handy if we don't always have time to watch a program live. Surprisingly, the TV also handles upscaling lower quality material quite well – standard TV channels look decent. It’s also suitable for gaming, though rather for those who are not avid gamers. Thanks to the low input lag and features like ALLM and HGiG, gaming is smooth, and the image is responsive enough. Sure, the 60 Hz panel does not allow for miracles, but it’s sufficient for occasional sessions. Of course, UT8100 is not for demanding movie buffs. The lack of Dolby Vision and HDR10+ means that HDR content does not look as good as it could. Brightness and contrast are rather average, which is particularly noticeable in the evenings, in dark scenes – blacks are not deep, causing details to easily get lost. LG UT8100 is a solid TV for those who are looking for simple equipment for everyday use. It has a comfortable system, a functional remote, and a few useful options, like USB recording. If we do not care about the highest image quality and are looking for something to watch TV, this model will perform quite well.

The LG UT8100 television is equipped with an IPS panel, which unfortunately fails to provide satisfactory contrast and black levels. In the tested scenes, such as from the movie Sicario 2, the black resembles a silvery ash rather than deep tar. The lack of local dimming causes details in the dark areas of the image to merge, and the screen appears quite bland in poorly lit rooms. For users seeking deep blacks and vivid contrast, the IPS panel in this model will be disappointing. In this category, the television performs very poorly.

The LG UT8100 television unfortunately does not meet expectations in the HDR effect category. The peak brightness of only 300 nits on the luminance graph is significantly 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 color palette is only 82%, which further limits the ability to present vibrant and rich colors. Instead of impressive visual experiences, we get a muted and washed-out image. For those looking for a television to fully utilize HDR content, the LG UT8100 model proves to be highly disappointing.

Scene from the movie “Pan” (about 2800 nits)

Scene from the movie “Billy Lynn” (about 1100 nits)

Although LG UT8100 has clear issues with brightness, we decided to test its capabilities in demanding scenes from the movies Pan and Billy Lynn's Long Halftime Walk, mastered at 4000 and 1000 nits, respectively. To our surprise, the picture looked really good. Despite the lower brightness, background light effects, such as the sun or reflections, did not blend together, maintaining clarity and dynamism. Similarly, in scenes from Billy Lynn, where contrast and details were also surprisingly good. This is thanks to the proper implementation of dynamic tone mapping, which allows the television to better adjust brightness and contrast to the limited capabilities of the panel. Therefore, we strongly recommend enabling this option to maximize the HDR potential of this model.

HDR luminance chart:

LG UT8100 TV only supports static HDR, such as HDR10, which is a limitation in the context of modern standards. Thanks to the previously mentioned dynamic tone mapping feature, HDR effects look quite good, especially in more demanding scenes. This feature helps to better manage brightness and contrast, which partially compensates for the lack of support for dynamic metadata. Unfortunately, the TV does not support formats such as Dolby Vision or HDR10+, which significantly improve image quality, especially in film and gaming content. Such support could significantly increase the device's appeal, making it easier to fully utilize the potential of modern HDR materials.

Static HDR10

Factory color reproduction

5.5/10

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

As for brightness characteristics, both HD and 4K content feature a high tonal boost. The gamma curve in both cases remains well below the reference value of 2.4, leading to excessive brightening of darker elements in the image. A similar problem is evident in the EOTF curve – in the case of 4K content, the TV struggles with proper brightness management, resulting in issues with screen brightness. This means that the factory settings of this model require significant adjustment to achieve better image quality.

Color reproduction after calibration

8/10

After calibrating the Filmmaker Mode, the gamma has been aligned to practically ideal, reference values, which significantly improved the overall tonal characteristics in HD content. 4K HDR content also looks better, although some issues are still visible at the end of the graph, where the curve deviates from the ideal. The EOTF curve performs worse, as the television struggles to maintain appropriate brightness values. As a result, the image in some scenes may be overly bright or slightly dimmed, which stems from the device's design. Nevertheless, the calibration has brought significant improvements, especially in the case of HD content, where tonal balance and color reproduction are now at a much higher level.

Smoothness of tonal transitions

9/10

The fluidity of tonal transitions in LG UT8100 is at a very high level. The color gradation is almost perfect, and the transitions between shades are smooth and free of visible seams. This is definitely one of the strong points of this model. Unfortunately, the unevenness of the panel's backlighting draws attention, which can be noticeable in more homogeneous scenes, particularly in the darker areas of the image. Although the gradation itself is excellent, the unevenness of the matrix slightly detracts from the overall impression of quality.

Image scaling and smoothness of tonal transitions

7.3/10

OK Smooth transition function

OK Image without overscan on the SD signal

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

Image scaling on LG UT8100 performs very well. The image presents itself decently, without major issues with edge aliasing. Details are preserved at a satisfactory level, which makes lower-resolution materials look really solid on this TV. As a result, users can enjoy watching older content without obvious quality flaws.

LG UT8100, equipped with a 60 Hz display, will be especially suitable for people watching movies. The television offers the TruMotion system with de-judder effect adjustment, allowing users to customize the fluidity of the image – from more choppy to exceptionally smooth, reminiscent of a soap opera effect, depending on user preferences.

Blur (native resolution, maximum refresh rate):

In terms of motion blur, the television performs average. The average pixel response time causes that slight smudges are noticeable, especially on dark backgrounds, although overall the situation is not the worst in this category of devices.

Viewing angles

6.3/10

Brightness drop at an angle of 45 degrees: 64%

Thanks to the use of an IPS panel, LG UT8100 offers quite good viewing angles. The image remains clear and does not lose much quality, even when viewed from the side. Colors are well preserved, and brightness and contrast decrease in a noticeable but moderate way. This is particularly important in rooms where viewers sit at different angles to the screen. In this category, the television performs solidly, standing out compared to models with VA panels.

TV efficiency during daytime
