6.0

Overall rating

LG UT8100 is a model that doesn’t try to pretend to be more than it is. Simple, functional, and performing well for everyday use. Its biggest advantage is the WebOS system – intuitive, fast, and rich in applications. With such support, 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 a bit like a mouse – just point at the screen and click what you want. Voice control in Polish? It works flawlessly, and we can confidently say that 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 seems like a small thing, but it can be useful if we don’t always have time to watch a programme live. Surprisingly, the TV also handles scaling of lower-quality materials well – standard TV channels look decent. It’s also suitable for gaming, though rather for those who are not hardcore 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 doesn’t allow for miracles, but it’s more than enough for occasional sessions. Of course, UT8100 isn’t for demanding movie lovers. The lack of Dolby Vision and HDR10+ means HDR content doesn’t look as good as it could. Brightness and contrast are also rather average, especially evident in the evenings during dark scenes – blacks aren’t deep, causing details to easily get lost. LG UT8100 is a solid TV for those looking for simple equipment for everyday use. It has a convenient system, functional remote, and a few useful options, like recording to USB. If we’re not concerned about the highest image quality and are looking for something to watch television, this model will work quite well.

Visibility of details in the lights:

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 more of a silvery ash than a deep pitch. The lack of local dimming causes details in the darker areas of the image to merge, and the screen looks quite dull in poorly lit rooms. For users seeking deep blacks and vivid contrast, the IPS panel in this model will be a disappointment. In this category, the television performs very poorly.

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.

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 films 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, the light effects in the background, such as the sun and reflections, did not wash out, maintaining readability and dynamism. Similarly, in the scenes from Billy Lynn, where contrast and detail were also surprisingly good. This is due to the correct implementation of dynamic tone mapping functionality, which allows the TV to better adjust brightness and contrast to the limited capabilities of the panel. Therefore, we definitely recommend turning on this option to make the most of the HDR potential in this model.

HDR luminance chart:

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

Smoothness of tonal transitions

9/10

The fluidity of tonal transitions in LG UT8100 is at a very high level. The colour gradation is nearly 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, attention is drawn to the unevenness of the panel's backlighting, which can be noticeable in more homogeneous scenes, especially in the darker parts of the image. Although the gradation itself performs excellently, the inconsistencies of the panel slightly detract from the overall impression of quality.

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.

Blur and motion smoothness

Maximum refresh rate of the panel: 60Hz

Film motion smoothing option: Yes

Blur reduction option: No

BFI function 60Hz: No

BFI function 120Hz: No

Brightness drop with BFI: 0%

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.

Blur (native resolution, maximum refresh rate):

In terms of trailing, the television performs averagely. The average response time of the pixels means that slight trails are noticeable, especially on dark backgrounds, although overall the situation is not the worst in this category of devices.

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.

Input lag

10/10

LG UT8100 achieves an impressively low input lag of 10 ms, which is a great result, especially for gamers. This TV provides quick response and smooth gameplay experience, even in fast-paced games.

LG UT8100 is well-suited as a monitor for work thanks to support for chroma 4:4:4, which ensures very good text readability, regardless of the background. When it comes to gaming, the TV offers a 60 Hz panel and low input lag, making it suitable for less demanding applications. Unfortunately, the lack of support for features such as G-Sync limits its capabilities in more advanced gaming scenarios.

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 picture remains clear and doesn't lose too much quality even when viewed from the side. Colours are well preserved, and brightness and contrast decrease in a noticeable but moderate way. This is particularly important in rooms where viewers are seated at different angles to the screen. In this category, the TV performs solidly, standing out against models with VA panels.

TV efficiency during daytime

Matrix coating: Satin

Reflection suppression: Average

Black levels during daytime: Good

LG UT8100 is equipped with a satin matrix coating that does a moderate job of reducing reflections. A brightness level of 350 cd/m² is adequate for moderate lighting conditions, such as a typical living room. However, in very bright rooms, the television may struggle to maintain image readability, especially on sunny days. It will perform best in environments where lighting can be partially controlled.

The TV offers access to virtually all popular apps, such as Netflix, YouTube, Disney+, and Amazon Prime Video, making it an excellent multimedia hub.

In terms of usability features, the TV meets most expectations. We find all the necessary TV tuners and the ability to record to USB, allowing for the saving of favourite programmes. It’s easy to connect a keyboard, headphones, or other devices via Bluetooth. Unfortunately, the lack of PiP (picture in picture) functionality may be a minor disappointment, although it’s not surprising at this price point.

Daily use of LG UT8100 is pure pleasure – the simplicity of operation and versatility of features mean it performs excellently as both a home TV and a multimedia device.

Notably, the support for Polish characters in subtitles and the ability to change the font colour allow users to customise the displayed text to their preferences.

The sound on LG UT8100 is basic and doesn’t stand out in any particular way. It's sufficient for everyday TV watching, but when it comes to more demanding content like movies or concerts, it may lack depth and dynamism. If we care about better sound quality, it will be necessary to connect an external audio system, such as a soundbar or home theatre. The built-in speakers do their job, but they won’t impress more discerning users.
