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 performs well for everyday use. Its greatest asset is the WebOS system – intuitive, fast, and rich in applications. With such a background, using Netflix or YouTube is hassle-free, and navigating the menu is a matter of moments. 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 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 may seem like a small thing, but it can be useful if we don't always have time to watch programmes live. Surprisingly, the television also handles scaling lower-quality content quite well – standard television channels look decent. It is also suitable for gaming, although rather for those who are not avid gamers. Thanks to the low input lag and ALLM and HGiG features, gaming is smooth, and the image is responsive enough. Sure, the 60 Hz panel doesn’t allow for miracles, but it is certainly sufficient for occasional sessions. Of course, UT8100 is not for demanding cinephiles. The lack of Dolby Vision and HDR10+ means that HDR content does not look as good as it could. Brightness and contrast are also 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 television for those looking for simple equipment for everyday use. It has a user-friendly system, a functional remote, and several useful options like recording to USB. If we do not care about the highest picture quality and are looking for something to watch television on, this model performs quite well.

Visibility of details in the lights:

The LG UT8100 television is equipped with an IPS panel, which unfortunately cannot provide satisfactory contrast and black levels. In the tested scenes, such as from the film Sicario 2, the black appears more like silvery ash than deep tar. The lack of local dimming causes details in the dark 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 disappointing. In this category, the television performs very poorly.

Unfortunately, the LG UT8100 television does not meet expectations in the HDR effect category. With a peak brightness of only 300 nits on the luminance chart, it is well below the required value to fully enjoy the 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%, further limiting the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and lacklustre image. For those looking for a television to fully utilise HDR content, the LG UT8100 model proves 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 respectively at 4000 and 1000 nits. To our surprise, the picture looked really good. Despite the lower brightness, the light effects in the background, such as the sun or reflections, did not merge, maintaining clarity and dynamism. Similarly, in scenes from Billy Lynn, where contrast and detail were also surprisingly good. This is thanks to the correct implementation of dynamic tone mapping, which allows the television to better adjust brightness and contrast to the limited capabilities of the panel. Therefore, we definitely recommend enabling this option to maximise the HDR potential in this model.

HDR luminance chart:

LG UT8100 TV only supports static HDR, such as HDR10, which is a certain limitation in the context of modern standards. Thanks to the previously mentioned dynamic tone mapping feature, HDR effects look quite decent, 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, particularly in film and gaming content. Such support could greatly enhance the appeal of the device, making it easier to fully utilise the potential of contemporary HDR materials.

Static HDR10

Smoothness of tonal transitions

9/10

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

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

The image scaling on LG UT8100 performs very well. The image looks decent, without significant issues with edge aliasing. Details are preserved at a satisfactory level, which makes lower resolution materials look truly solid on this television. This allows users to enjoy watching older content without noticeable flaws in quality.

Blur and motion smoothness

4.9/10

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 films. The television offers the TruMotion system with de-judder effect adjustment, allowing you to customise the smoothness of the image – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on the user's preferences.

Blur (native resolution, maximum refresh rate):

In terms of motion blur, the television performs averagely. The average response time of the pixels means that slight trails are noticeable, especially on a dark background, 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 access to settings easier. The television also supports HGiG, which improves image quality in HDR games. Unfortunately, the lack of support for Dolby Vision and VRR limits the capabilities of the device, as does the 60 Hz panel, which excludes support for 120 Hz resolution. This model is more suitable for less demanding gaming applications.

Input lag

10/10

LG UT8100 achieves an impressively low input lag of 10 ms, which is an excellent result, especially for gamers. As a result, this television provides quick response times and smooth experiences during gameplay, even in fast-paced games.

LG UT8100 will serve well as a work monitor thanks to support for chroma 4:4:4, which ensures very good legibility of text, regardless of the background. In terms of gaming, the television 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 matrix, LG UT8100 offers quite good viewing angles. The picture remains sharp 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 degree. 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 matrices.

TV efficiency during daytime

4.6/10

Matrix coating: Satin

Reflection suppression: Average

Black levels during daytime: Good

LG UT8100 has been equipped with a satin coating on the panel, which performs moderately well in reducing reflections. A brightness level of 350 cd/m² is sufficient in moderate lighting conditions, such as a typical living room. However, in very bright rooms, the television may struggle to maintain image readability, particularly on sunny days. It will perform best in settings where the lighting can be partially controlled.

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

In terms of user functions, the television meets most expectations. Here we find all the necessary TV tuners and the ability to record to USB, allowing for the saving of favourite programmes. It is easy to connect a keyboard, headphones or other devices via Bluetooth. Unfortunately, the lack of PiP (picture in picture) functionality may be a slight disappointment, although at this price, it is not a surprise.

Everyday use of LG UT8100 is pure pleasure – the simplicity of operation and versatility of features make it work excellently both as a home television and as a multimedia device.

Special praise should be given to the support for Polish characters in subtitles and the ability to change the font colour, allowing users to customise the displayed text to their own preferences. In this category, the television performs really well.

The sound in LG UT8100 is basic and does not stand out in any particular way. It is sufficient for everyday TV watching, but for more demanding content, such as films 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 cinema. The built-in speakers serve their purpose, but they will not impress more discerning users.
