LG UP81 Review: 4K Ultra HD TV that will exceed your expectations


A new year began and many brands have started to work on their new models, obviously LG was not going to be left behind in that sense and has already released a more than interesting model. Especially if we consider the different features it includes. Today we are going to delve into the analysis of the LG UP81, a more than interesting option.

Mainly if you are planning to renew your old TV and want to get into the new features that are currently offered, since the LG 55UP8100 is considered in the high-end category , therefore, its value may be a bit high, however, after checking its operation it may be totally worth it.

The design seen last year is maintained a bit, however, it still looks good in any position

On an aesthetic level, the LG 55UP81006LA.AEU does not change much compared to several models presented last year, therefore, there will not be many details that are going to make a difference. However, this does not mean that its design is bad, on the contrary, it still looks good, in addition, we are talking about a TV with a somewhat large size .

For this reason, it is ideal for large rooms, likewise, its chassis comes in black, which fascinates us because of the integration it has with the decoration of the place where it is placed . Another important detail is that its front gives us quite slim bezels that unleash incredible elegance from almost any angle.

As if that were not enough, this also suits the screen as such, since it will have a much wider useful space that is perfect when it comes to watching content, so we will not have obstacles as is sometimes seen by thicker frames . The back has a clean construction and at all times it is sought to respect the thin term.


Something that we have been liking about the new televisions that are coming out is that some models reduced the number of connectors available, and only those that are truly indispensable are integrated, for example, its three HDMI 2.0 inputs to connect various devices such as laptops, consoles or players. There are also two USB 2.0 that serve to reproduce content, although its most notable advantage is the possibility of recording .

Other connections that can also be widely used are its fiber optic input for an incredible transmission speed, likewise, it has an Ethernet port that allows us to connect the TV directly to the Router and receive a better internet signal, although This forces us to keep the team close. Let’s move on to wireless where we have Wi-Fi Direct and Bluetooth 5.0 excellent options to connect.

Image quality and functions in general of the LG 55UP81006LA

Nothing bad to say about the great image quality that the LG 55UP81006LA gives us , since it is perfect to enjoy any content with more than obvious clarity. This is achieved thanks to its 4K resolution that offers greater power to receive realistic images, likewise, we witness a number of deeper details .

It is accompanied by a Direct LED panel that for obvious reasons we are going to consider the weakest for this issue, since the backlighting that it gives us is a bit weak for the need for a television like this. Especially if we are in very dark or bright areas , therefore, the placement will also be important so as not to lose quality.

The good thing is that different improvement technologies are implemented that will be of great help so that the final result is not greatly affected. For example, we have Dynamic Color that seeks to show more accurate and vivid colors so that each scene becomes more realistic. With 4K Upscaler , quality is increased regardless of definition.

To receive a sharper and more precise contrast , LG Local Contrast is available , although this parameter also benefits from its dynamic formats such as HDR10 Pro and HLG that are normally already found in most content. Noise Reduction gives us a reduction of noise in the image for more fluid scenes.


The audio quality is more than acceptable at a general level, however, we believe that your speakers could have included a little more power , since they maintain what is normally offered in the mid-range, we are talking about 20W total than in certain content they are not sufficient for a deeper or more precise experience as the case may be.

Here the real advantage is received in all the enhancement technologies that have been implemented, for example, we have Clear Voice to hear clearer dialogues. For its part, Dolby Digital , LG Sound Sync and Sound Mode Sync give us a much more immersive and clean experience that we also have thanks to Ultra Surround .

For this model they have decided to integrate the latest version of their own webOS system

The LG 55UP8100 already comes with webOS 6.0 which turns out to be the latest update of this great system that continues to improve its optimization and security, in addition, navigation between the different available sections feels even more fluid . As if that were not enough, we have a wide catalog of applications to install on the TV.

Obviously, the most popular options such as Netflix , YouTube , Prime Video , Disney + and Apple TV are included . With these applications we have an incredible amount of movies and series to enjoy. Do not forget that with Google Assistant and Amazon Alexa we can control certain functions using only the voice.

In order to receive a cinematographic experience, we have Filmmaker Mode that reproduces the films as the director prepared them. Another application that we cannot leave out is Apple AirPlay 2 that allows us to transmit images, videos and music from an iPhone or iPad. Without a doubt, the LG 55UP81006LA.AEU is a good option.
