LG UT640S Review: A TV suited for business environments


Not all televisions are focused on entertainment, in fact, there is a line that is directed to the work that can be done in a company. A brand that has stood out with these models is LG, which has an interesting catalog. Precisely today we want to talk about the LG UT640S which seems to us a quite interesting option.

Exterior design of the LG UT640S

It is not a spectacular design, however, it has interesting details

First, we want to talk about its aesthetics, which we must say is something simple, however, we have found that it usually fits well in almost any environment . That in principle is because it has a size of 49 inches that is perfect for medium rooms, in addition, it comes in a black color that seeks to give it a greater presence.

As if that were not enough, it gives us slightly thin bezels that will give it greater elegance regardless of the angle from which it is viewed. This same allows that the reproduction of content has a greater space on the screen . The back features a slim style that can perfectly match the décor.


We have the necessary connectors for a good user experience, here we find two HDMI 2.0 inputs that will be the fundamental piece, since they allow us to connect different external devices and make use of their signal. We must also have a USB 2.0 that allows us to play content directly on the television. In the specifications table you will find the rest of the physical connections. Of course, we do not have wireless options.

Image quality and functions in general

Although the LG UT640S is not a television focused on the reproduction of content, we must mention that it offers us an interesting resolution that can be sensational in case of giving it a different use. We are going to have a 4K definition that due to its power will show us better details, which will look more realistic .

To further improve the performance in its image quality, we are going to have a 4K scaler that automatically updates the content in Full HD, likewise, we must emphasize that it has an IPS panel that offers us a more vivid and intense color , so Therefore, we will have an enveloping view. Of course, its backlighting is something basic.


One of the weakest points of this model is found in its audio quality that only offers us 20W. It might not seem like such a bad thing, however, for more demanding content we will find problems . Another detail to consider is that it does not offer enhancement technologies, therefore, there is nothing that will improve the experience.

Notable features of this TV

It has certain functions that will be quite useful when working

Let’s talk about how important the LG 49UT640S offers , as it has some quite useful features in the business environment. To begin with, we have group management and integrated content that will allow us to edit and reproduce content. It also allows the company to control it via remote control .

For its part, SuperSign control is integrated , which is a basic software that allows us to manage up to 100 screens through a single account. Finally, we will also have data cloning via USB that will increase our efficiency in managing multiple screens in search of a totally optimal and safe operation.
