Among LG’s 4K TVs in 2019, the UM series brings together the simplest models. The UM7650 is an IPS panel input TV, HDR content support, and the Smart Magic remote control, which acts as a mouse to navigate webOS platform applications.

With a launch price of $ 3,499, the UM7650 competes with other competing entry-level TVs, such as the Samsung RU7100, Sony X705F and TCL C6. Is LG a good option for not wasting your eyes on a 4K TV? I’ve watched dozens of hours of movies and series on the UM7650 in the last few weeks and tell it all in the next few minutes.

The design of the LG UM7650 follows the input TV primer: a lot of plastic, no fancy finish, and nothing unintentional. The frame and bow-shaped base are silver, as is usual with LG. The back is smooth and has no specific solution for hiding the cables behind the TV, like the channels we are seeing in the basic Samsung and Sony models.

Connections are concentrated on the left, with two USB ports, a coaxial cable input supporting the Brazilian digital TV standard, an optical audio output and an Ethernet port. The TV has Bluetooth, so you can wirelessly connect headphones and speakers, or go the other way, transmitting the sound from your phone to your TV.

A nice point is that even on a more affordable model, LG has put four HDMI ports, one more than usual in this price range. Two HDMI inputs face left and the other two face back. Another advantage is that the UM7650 typically connects to 5 GHz Wi-Fi networks, unlike competitor Samsung RU7100, which only supports the old 2.4 GHz standard.

The remote included in the box is Smart Magic, which also works as a kind of mouse. It was good news for LG’s basic TVs of past generations, which had a simpler accessory. This is the same remote you find on LG premium TVs, with voice command support, a scroll to scroll screens, and the ability to control other devices, such as the pay-TV decoder.

The model I tested came with a 55-inch IPS-type panel, with good image quality, within the technology and price range. In marketing, LG often highlights the wide angle of view: the promise is “almost 100% accurate color, even at a 60 degree angle”.

In practice, this is true: even sitting at an angle of approximately 45 degrees, the UM7650 still shows vivid color without any fading, unlike what would happen with a VA panel TV, like most Samsung and TCL models. Only the brightness is slightly reduced, but the experience is still good. It’s a TV that I would recommend to anyone with a larger living room where not everyone can sit right in front of the TV.

At factory image settings, colors are not too saturated and white tends to a cooler tone, but fine adjustments can be made. And, after being heavily attacked by the competition, LG has made less use of the white pixel RGBW panels, which are worse defined in some cases – the 55-inch UM7650 sold in Brazil has the traditional RGB scheme.

But it’s not all flowers: we’re still talking about a more affordable TV with an IPS panel. At first, it bothered me a lot about the contrast: black is grayish and inconsistent, and you can see certain “clouds” on the screen in darker scenes, something I haven’t seen on other basic TVs like the TCL C6. Because of the low contrast and not so bright brightness, HDR makes almost no difference to the UM7650, although TV theoretically supports this technology.

Image processing has positive and negative points. Upscaling works well, making Full HD images sharp in the 4K panel without creating noise or hard edges around objects. But the motion tween, which LG calls TruMotion, was below expectations. I like the “novel effect” (sorry, Tom Cruise), but I decided to disable the feature on the UM7650 because it created nasty artifacts in faster motion and “punched” the image, as if TruMotion was turned on and off at random times.

Overall, the UM7650’s image meets the expectations of a TV that doesn’t cost the eye. Those who have a larger home environment to install the TV can benefit from the above average viewing angle. On the other hand, if you often watch TV sitting on a sofa in front of you, this may not be the best option: it is better to look for one with more consistent blacks and better contrast, especially for marathon series at night.

TV Sound quality

Input TVs do not usually have good sound quality, but LG could have capriced a little more. On the plus side, the UM7650 can achieve very high volume levels sufficient to fill a larger environment, which makes sense for an IPS panel TV. On the other hand, the dynamic range is not so wide, not reaching the lower frequencies.

Both 10-watt speakers have a good midrange, but it seems LG has tried to compensate for the bass with an increase in mid-bass, whether in Standard or Cinema sound profile. The result is that the sound appears to be “dirty”: you don’t feel the beats of a song or an explosion, but you hear some muffled noises. Not a very good equalization, and any soundbar would be a considerable upgrade.

Smart TV software and functions

The UM7650 operating system is the same webOS that comes with all LG Smart TVs, but I need to highlight a few points compared to the LG B8, the last one I had tested with this platform. There was a minor version update (from 4.0 to 4.5), which was enough to fix problems.

The first point is that Smart Magic worked as a universal remote control as soon as I turned on the TV for the first time. After going through the initial setup, webOS detected the model of my pay-TV decoder and released channel switching and access to the programming guide, unlike B8, where I needed to do some trickery. The TV just missed the carrier name (she thinks I subscribe to AT&T), but everything else worked perfectly.

Another novelty is the Home Panel. 2019 is the year that all manufacturers are talking about connected home in Brazil, and LG has decided to deploy a screen that centralizes all smart devices in the home. Unfortunately, the SmartThinQ platform is somewhat limited, basically supporting LG refrigerators and washing machines. But TV has OCF support, so it’s likely that the compatibility list will grow over time.

The rest of webOS needs no big presentations. It’s an easy-to-use operating system with a selection of applications that should suit almost all users – it could be a little more fluid, but not bothering at all. Services like YouTube, Netflix, Prime Video and Vivo Play come pre-installed, and in the app store you can find Telecine Play, Globoplay, Fox, Spotify and Deezer.

Worth it?

The UM7650 is a good all-in-one TV overall and great for specific cases. LG is one of the few manufacturers that continues to focus heavily on IPS panels on LCD TVs, which favors audiences with larger living rooms. While some TVs easily have faded colors for those who sit at wider angles, the UM7650 continues to show everything with vividness.

The news in the 2019 line were also great. WebOS has continued to evolve, consolidating itself as one of the best Smart TV platforms in the industry; And it’s good to see that the Smart Magic remote control, which was restricted to some more expensive models, is available in the box even for those who don’t want to spend so much money on a TV.

My main period of content consumption on TV is at night, so of course I missed a deeper black. At default settings, LG makes the panel’s contrast deficiency very clear: in “near black” scenes, the TV abruptly turns off the backlight, which ends the setting. And because the brightness is just ok, the UM7650 can’t offer more than rice beans in picture quality.

Despite the few negatives, LG has made a TV that can please most people: picture quality is not to be missed; the design is simple and a little thick, but not crude; and the well-evolved webOS operating system now offers just about everything you need.
