The UN8000 is the representative of LG in the segment of 4K TVs that do not cost the eyes of the face, at least in smaller sizes. The 50-inch version can be found in retail for R $ 2,500 or even less in promotions, but the manufacturer also decided to serve those looking for a home cinema, with versions up to 86 inches in the Brazilian market.
Regardless of size, LG put everything it could into a simple 4K model that is one notch below the NanoCell line. The UN8000 competes in one of the most popular segments in Brazil and wants to win users with its thin edges, Smart Magic remote control and new functions in the software. But is the image good? I tested LG’s new ThinQ AI UHD and count my impressions in this review.
Review of the LG UN80 (50UN8000) on video

Design, connections and remote control
The UN8000 has a simple finish and plastic construction, but the design is sober and elegant. The brushed metal-like edges are relatively thin and have bevels that create the feeling that the frame is more compact than it really is. The two silver V-shaped feet at the ends of the screen make the TV stand firmly on furniture.
The connections are on the left side and include an optical audio output, two USB, Ethernet and component video. As expected for a basic model, the screen is 60 Hz and eliminates the need for HDMI 2.1 ports, but LG gains points for maintaining four video inputs, an increasingly rare detail in this price range. Samsung, for example, only includes three HDMI ports on the TU8000 and even launched a TU7000 with only two ports. I hope LG does not follow this trend.
The Smart Magic remote control has become standard on LG’s new line of TVs and also comes with the UN8000. It has many buttons, is not so compact and requires initial motor coordination training to navigate the elements of the screen with a mouse in the air. A button allows you to quickly open Netflix, while the Amazon Prime Video shortcut has a dual function and can also trigger Alexa.
The image quality of the UN8000 disappointed me the first time I turned on the TV. My testing unit had a very visible backlight leak, which seriously affected the uniformity of black, causing discomfort whenever a darker image appeared on a film, or even during transitions between applications, when the screen goes black and the problem it is wide open.
Unlike what usually happens in entry-level TVs with edge lighting, the UN8000 can even maintain uniform black in the corners of the screen, but my unit shows a white cloud across the top third. It is a flaw that greatly affects the experience because it can be easily noticed by any ordinary person. Even considering the price range, the problem should not be tolerated by the manufacturer’s quality control.
Elsewhere, the UN8000 panel did not deliver anything far beyond the obligation, especially knowing that this is not the cheapest 4K TV of the brand; there are also the UN7310, UN7300 and UN7100 models, which are below it and have different panels. The brightness is stronger than the average of the segment, but the contrast is impaired by the black level, which, in addition to not being uniform, is not very deep, presenting shades that are grayer than expected.
The volume of colors is average, leaving a very small color banding, but that can bother the most detailed. Even adjusting a configuration called “Smooth gradation”, I didn’t get results that were so different from the standard. And the viewing angle, a strength that LG had on IPS panels, is mediocre on the 50-inch UN8000, making the colors wash out if you sit at an angle of 30 degrees or more from the screen.
Despite my tone, the UN8000 is not a bad TV: if you don’t have the problem of a backlight leak, the image quality comes close to the Samsung TU8000 Crystal UHD, with the advantage of a better brightness at LG. But it is clear that the brand could have done a much better job in this entry category, before moving up to NanoCell.
The 20 watt speakers are within what I expect for a TV without great sound pretensions. The downside is the low presence in the bass, which makes the sound thin and emotionless in action movies. On the other hand, LG excels in volume, which is loud enough even for large living rooms, an important point for those who decide to purchase the UN8000 in larger sizes, 82 or 86 inches (but in this case, you would probably go want to install a sound system anyway).
If the speakers are not impressive due to low frequencies or numbers, at least LG is able to improve the sound experience by software a little. In Sound IA mode, the voices are very clear on traditional TV channel content, such as news programs, while the songs maintain their dynamics, without serious distortions even at higher volumes.
Smart TV software and functions
UN8000 runs the webOS 5.2 operating system, which stands out for its colorful and animated screens. The app offering is good, with Netflix, Amazon Prime Video, Disney +, YouTube, Apple TV +, Spotify, Globoplay, Telecine and more in the LG content store. A notable absence is DirecTV Go, which was not yet available for any brand TV at the time of publication of this review.
The default personal assistant is Google Assistant, which responds quickly but needs to be triggered manually by the microphone button, since the hands-free feature has been restricted to LG’s ultra-thin models in this generation. The shortcut to Amazon Prime Video on the remote can turn into a button for Alexa with a long press.
Also present in other 2020 TVs from LG, the Control Panel allows you to control compatible smart home devices. It is also possible to mirror content with Miracast or Apple AirPlay, as well as activate the sound sharing feature, which turns the TV’s integrated speakers into a Bluetooth speaker for your phone.
The UN8000 is a satisfactory TV. The big problem was the backlight leak in my test unit, but the intensity of this failure can be lower or higher depending on the consumer’s luck. Brightness is a plus for LG’s entry-level 4K TV, as well as a good supply of connections, a very complete operating system and intuitive remote control.
However, LG leaves a bit of disappointment in the contrast, which could be better, as well as the viewing angle, which was an old strength of the brand and was left out on the 50-inch UN8000. Anyone migrating from an old LCD TV with Full HD resolution should notice a nice difference with the upgrade, but anyone who has paid attention to a higher quality 4K TV may be a little dissatisfied.
In relation to Samsung TU8000, its main competitor, LG can gain supporters by the greater number of HDMI ports, by the brightness to cope with clear environments and by the speakers with more sound pressure. I only question LG’s strange strategy with the UN8000 in Brazil: above the 50-inch version, only very large sizes of 75, 82 and 86 inches are available. So it’s all or nothing.
