Exterior design of the LG 55UP81003LA

LG 55UP81003LA design

We have a clean design that stands out in almost any position where it is placed

The first thing we should highlight about the LG 55UP8100 is that it gives us a clean appearance that in our view can fit perfectly in any location. To begin with, a front with thin bezels is presented , which provide greater elegance regardless of the placement, since we will have a more modern and minimalist appearance.

Likewise, the useful space on the screen will be wider, therefore, the reproduction of content will be better and there will be no hindrance. When turning the television over, we will realize that the back also respects its slim appearance , so, in general, we will enjoy a well-crafted aesthetic that will stand out a lot.


We will have the essential connectors for a good experience, for example, its three HDMI 2.0 inputs to connect external devices, likewise, two USB 2.0 with double function are provided, that is, we will be able to play or record content. At the wireless level we will find Wi-Fi , Bluetooth 5.0 and DLNA .

Image quality and general functions of the LG 55UP8100

The LG 55UP81003LA gives us a great experience in terms of image despite not being such an advanced model. The first thing we should know is that we have a 4K resolution that provides greater power than Full HD, therefore, we will receive better details in any content , in addition, it offers interesting improvement technologies.

Before talking a bit about them, we must know that your panel is Direct LED and that you may have little difficulties in very dark or bright environments. However, this is enhanced with features that focus on core parameters such as color , contrast , brightness, and movements for a much more streamlined experience.


This model has two speakers that give us a total power of 20W, which could be considered the weakest and we say this because its power is not enough in more demanding content, yes, we will have interesting technologies such as Adaptive Sound Control , AI Sound , Bluetooth Surround , Clear Voice and Dolby Digital .

Enjoy great features by including the webOS system

One of the main attractions of the LG 55UP8100 is that it has its own system, which offers us a great experience. For starters, it has a really impressive application catalog that adds the most popular options, as well as it includes compatibility with Google Assistant and Alexa to control functions with your voice.

As if that were not enough, it also offers the Apple AirPlay 2 application that allows us to transmit all kinds of content from an iPhone, iPad or Mac in a fairly simple way. It may not seem like it, but this model includes Game Optimizer to enhance the gaming experience. Finally, know that you can use HDR10 Pro and HLG .
