LG UP78 Review: Affordable TV with great image quality and design

LG’s mid-range   continues to offer us very interesting televisions that are usually a notch above other not so popular firms.  This is mainly due to the features that it integrates for its operation . Where most are sufficient to meet general needs. We are talking about the LG UP78.

This TV seems to us an excellent option for different points that we will detail later, however, it also has some negative sections that could put your purchase in doubt. Although we consider that there are more benefits that we can receive , so, it is time to learn more about what the LG UP78 includes.

Exterior design

We have a regular design that stands out for its easy installation in almost any environment

Although its design is the typical one that we have already seen in several mid-range models,  we must accept that its appearance is pleasant to us  and  we believe that its elaboration is correct , at least if we balance it with what has already been seen in others. brands. As if that were not enough, being 49 inches we will notice that it fits almost anywhere.

The reality is that it is not a very elegant look that is going to stand out too much, however, it has more positive points than bad. For example, its front shows thin bezels that will make better use of the space on the screen. With this we achieve that the visualization of the content is more complete .

The sides and back have a slim style that suits the design quite well. As negative points we can mention that the construction materials feel somewhat weak , in addition, the space behind is a bit neglected due to the position of the screws. The rest of the appearance is in line with what we might expect.


In this section we will not find any problems either,  since we have the necessary connectors for a good experience . Here we find a USB 2.0 port that apart from allowing us to play multimedia content, we can also use them to record content from the television. Likewise, we have two HDMI 2.0  that usually have very good compatibility with  laptops ,  consoles  and  video player .

Without a doubt, the most important thing will be to know what options we have at the wireless level, since it is currently the most used connectivity. To begin with, we have the classic  Wi-Fi  for internet use, however, the most striking option is  Bluetooth 5.0  which, due to its version, offers us better stability when connecting headphones or wireless sound bars. To transfer content from the smartphone we can make use of  DLNA.

Image quality and general functions of the LG UP78

The  LG 43UP7800  has an interesting image quality, obviously it is still far from offering what is seen in more advanced models, however,  we believe that it can be taken advantage of with almost any content . First, we find a 4K resolution that will show us a greater amount of detail.

This definition is accompanied by an LED backlight   that seeks to give us a better precision of blacks, however,  what is offered is not the most spectacular that we can enjoy . At this point we can recommend that you avoid placing the TV in a place where there is a lot of light,  as it can affect the experience .

This model does not include as many improvements as that witnessed in other series, therefore, the final result is not so incredible. Despite this, it integrates some technologies that seek to give a better response to the image . At this point we notice an improvement in color, contrast and saturation that are essential when viewing content.

In addition, the processor that is included tries to eliminate the greatest amount of noise, in order to offer more fluid and precise movement. Let’s not forget that it includes HDR technology that will offer us more vibrant colors  and  contrasts . Finally, mention that it includes upscaling that improves 2K, Full HD and HD resolutions.


It may be that the sound is one of the main shortcomings of this TV, and we do not say it because it is a terrible audio, in fact,  in general terms it offers an acceptable power . However, the problem begins to be noticed when we are going to reproduce more demanding content. What we notice is that there is a lack of greater power in the speakers,  since this model, like many, only offers 20W that does not end up completely convincing us .

Perhaps the only advantage compared to televisions in this range is that it includes certain technologies that seek to give us a more enveloping and clear sound. For example,  Clear Voice  tries to give us a cleaner dialogue, likewise,  Dolby Digital, LG Sound Sync and AI Sound  seek a more immersive audio. However, to receive a truly acceptable quality the only possible option is to purchase an external soundbar  that is not so expensive.

Smart TV / software review and more highlights

We have one of the most complete systems today, which fills us with great benefits

The LG 43UP78003LB may be entirely worth your while thanks to the  webOS operating system  that is manufactured by the firm itself. In this latest update we have an improvement in optimization and security. In addition, it includes compatibility with  Apple TV ,  Disney +, YouTube, Netflix, Prime Video  among other options that we have in its extensive catalog.

Another attraction that we find is that by including  artificial intelligence  we can make use of the integrated voice assistant, which in this case is Google Assistant, with this we can perform multiple actions without the need to use the remote control. It also includes Apple AirPlay 2 to send music ,  photos  and  videos  from an iPhone or iPad.

This model includes a game mode that seeks to optimize our experience, obviously it will not be something surprising, however, it  considerably reduces the Input Lag  and  is enough to enjoy a more fluid game . Finally, mention that we can activate sports notifications so as not to lose the result of any match.
