In preparing the article, materials from https://www.giztele.com/lg-70un74003la-caracteristicas-precio-opiniones/ were used. Visit article here.

The quality that LG offers us in its televisions is not in doubt, it is usually a very reliable brand that has a really extensive catalog. However, we must consider that their equipment, regardless of the range, always have a higher price, however, these are usually quite worth it . Proof of this is the LG UN74 that presents us with great characteristics in general terms.

Of course, we are talking about a fairly large TV that requires a much larger space when placing it. Nor is it the most complete or advanced model , in fact, we remain in the mid-range, so, in the first instance, we must be clear about our requirements so as not to make a purchase in vain. Without further ado, we are going to know what the LG 70UN7400 has to offer us.

Exterior design of the LG UN74

LG 70UN74003LA design

A clean design that tends to fit well in almost any environment due to its size

The design that we have seen in other series of this same brand is maintained, therefore, we will not find many differences to highlight . Of course, in our opinion we have an acceptable appearance that stands out for the simple details that have been integrated. Which stand out more on a large TV.

We must emphasize that they have thin bezels that in turn implement modern lines that generate great elegance. This allows us to enjoy an exceptional aesthetic that looks completely in any room or room. Without a doubt, the front is the most positive thing we find in this design .

The view from the sides is also pleasant, since it is not as exaggerated as in other cases . This keeps us a slim style that can be perfect if we decide to occupy the VESA mount. Without a doubt, the only negative we found is that its construction materials are quite weak.


We have the possibility of connecting our external devices via HDMI , the advantage is that we have three inputs to connect variety. They are usually used for laptops, consoles and players. Its two USB 2.0 ports allow us to record content from the television, yes, for its version the transfer with heavy files will be very slow, for the rest everything seems correct.

Other interesting physical options are its composite video input , a digital audio output , an RS-232C port and two RF ports . In the wireless we have a Wi-Fi connection to use the internet from a distance. The main advantage that we find in its compatibility with Bluetooth 5.0 that it is perfect for connecting headphones or wireless sound bars with great stability.

Image quality and functions in general

Enjoy sufficient image quality to enjoy all your content

The LG 70UN74003LA gives us an acceptable image quality that has what it takes for all our content to be displayed clearly. Obviously we are not saying that it is something incredible , however, for its possibilities it seems correct and we believe that it easily surpasses several of its competition.

We have a 4K resolution that seeks to deliver more realistic images, especially if the content is native in that definition . However, we have the advantage of having 4K Upscaler that seeks to increase the quality of content with lower definitions, thus seeking to maintain the maximum experience at all times.

As a negative point we can mention that its Direct LED panel offers us a somewhat poor backlighting, especially if we are in very dark or bright environments, therefore, the location of the TV can be essential . It is not a very serious problem, but there may be quality losses.

Taking this into account, the rest of the parameters have a more acceptable balance that gives us a clearer display. Mainly the colors that will be more optimized, which gives us a more real experience from any angle . Do not forget that it has compatibility with HDR10 Pro and HLG Pro .

Other advantages that we cannot overlook is that its processor automatically deactivates the motion interpolation, thus we obtain the effect of more fluid and precise images. In addition, it also takes care of removing noise from the video and creates a more vibrant contrast . All this ends up giving us an advantage.


Not everything is perfect and we are also going to find some points to improve. The most obvious is its audio quality that seems a bit limited , especially for a television of this size that should include a powerful sound. In this case we only find two speakers that transmit 20W of power, something very common in the current mid-range.

In general terms, the listening experience is acceptable, however, in more demanding content such as action movies or video games we will notice its weakness, mainly in the dialogues that are usually the most affected. For that, enhancement technologies such as Dolby Audio and Clear Voice III are integrated that will give us a more immersive experience, however, it is not enough.

Analysis of the software / Smart TV and more functions of the LG UN74

LG 70UN74003LA Smart TV

Among its main benefits we include the latest version of the webOS system

Where the LG UN74 stands out the most is in its operating system, which is typical of the brand and offers us excellent possibilities. To begin with, its latest version is integrated and this gives us a high improvement in its security and optimization, therefore, we are talking about a fluid platform in its navigation between menus .

Likewise, we have an extensive catalog of applications that gives us the most popular options, especially if we talk about streaming, since we have Netflix , Prime Video , YouTube and Disney + so we will have a very wide catalog of movies and series. In addition, other equally important apps are added.

Another advantage that we cannot ignore is that we can use the LG 70UN7400 with voice assistants, that is, we can control some actions without using the remote. We also enjoy Apple AirPlay 2 to transmit photos, videos and music from an iPhone or iPad with total freedom and security.
