LG UM7300PUA Review

LG UM7300PUA Review

Last Updated on by Daniel Lawrence

LG’s UM7300 ($649 for the 65-inch model) is a 4K smart TV that boasts wide viewing angles and a full-featured smart TV experience. In terms of features, the UM7300 does not possess some of the strongest features you will find on the best TVs, even on some in the same price range. Although it lacks local dimming and only supports limited HDR, it provides an excellent gaming experience coupled with an excellent smart TV interface.

LG UM7300 design

The LG UM7300 offers a more modest design than the LG UM7500 and LG UM7000 premium sets. Design-wise, it has chunky black bezels around the screen, a basic stand, and a mostly featureless black plastic rear panel, which tapers around the top and sides for a less boxy appearance.

Without the stand, the UM7300 measures 57.6 x 33.5 x 3.5 inches and needs two people to set up. With almost 3.5 inches of thickness through most of its chassis, the UM7300 is quite thick.

As a result, the UM7300 doesn’t make sense for wall mounting, since it will stick out of the wall several inches, and there isn’t much room for the internal components and speakers. However, the UM7300 has a VESA mount that accommodates 300 x 300 millimeters if you intend to mount it on the wall. This 65-inch monitor weighs 47 pounds.

LG UM7300 ports

UM7300PUA features three HDMI ports, two USB ports, a coaxial connector for connecting an antenna, and composite and component video inputs. With an Ethernet port and 802.11ac Wi-Fi built-in, the TV can connect to your home network.

Two HDMI ports and a USB port are located on a left-facing panel, with the remainder of the ports located on a rear-facing panel.

The second HDMI port on a soundbar supports an audio return channel (sometimes referred to as HDMI ARC), allowing you to use a single HDMI connection for all audio.

LG UM7300 performance

LG’s UM7300 delivers the basics perfectly, giving you most (but not all) of the features expected from a 4K TV. With its 65-inch display, you can view content with a full 3840 x 2160 resolution. Watching the 65-inch TV, however, I noticed some real issues.

Color quality was the first consideration. I noticed the colors used in Spider-Man: Homecoming was a little washed out, with skin tones and reds looking a little pale, while blues and reds didn’t look like they should.

It appears that my initial impressions have been confirmed by lab tests. We measured the UM7300’s reproduction accuracy using our X-Rite colorimeter and found it to reproduce only 97.9% of Rec 709 color spaces. While that’s not far off from other affordable sets we’ve tested, like the TCL 55S425 (97.2%) and the Samsung RU7100 50-inch (96.3%), it’s a noticeable difference from the excellent Vizio M-Series Quantum (99.9%), which is far closer to the 100% we expect from a 4K TV.

The UN7300 delivered better color accuracy measurements, with a Delta-E rating of 1.9 (closer to zero is better). This is slightly better than the Vizio M-Series Quantum’s score (3,6), but it is less precise than the Samsung RU7100’s (2.0) and the TCL 55S425’s (1.4).

You will be able to watch the TV’s picture from any angle, with minimal color shifting when viewed from the side, thanks to its IPS display. We also noticed that the UM7300’s black levels are inherently poor thanks to IPS displays.

In contrast to less expensive TVs that use edge-lit backlighting, the UM7300 uses direct backlighting, with the lights embedded behind the LCD panel. As a result, the high dynamic range (HDR) performance is severely limited, as well as the black-level performance, which is enhanced by the backlight’s brightness. There is no support for Dolby Vision or other high-end formats, like HDR10 and hybrid log gamma (HLG). The overall contrast isn’t great when there is no local dimming. Brights can ramp up pretty high, but there is no local dimming. After washing out all the black and shadow tones, the image shows a glowing gray.

I saw a scene from Creed II where pyres of flame and laser lights filled the entrances of the arena, but instead of making a huge impact against the darkness, these elements lacked the sharp contrast required to catch the eye in contrast with the darkness. HDR still delivered a better picture than older standard dynamic range TVs, but not nearly at the level of even modestly priced HDR-enabled sets.

Additionally, I saw some mediocre motion handling. Whenever something moved quickly onscreen, whether it was the web-slinging action of Spider-Man: Homecoming or the flying fists of Creed II, a fast motion introduced many undesirable artifacts, and hazy smearing was evident. When the film mode was switched on, and motion smoothing was enabled, these problems disappeared, but not entirely. I encountered jerky motion rather than smooth motion and smearing rather than crisp details in every mode.

LG UM7300 gaming

Gaming is one area where UM7300 excels. Upon connecting our Xbox One X to the TV, we were pleasantly surprised to see it detect the console and switch over to a special deep-color mode that supports the 10-bit color of the console.

As with the TV, the support was good overall but came with some limitations. Game streams will support various frame rates (24, 50, and 60 Hz), but HDR will only be supported in HDR10. Similarly, the TV cannot display Dolby Vision content.

In our testing of UM7300 input lag, we found impressive results. The games we’ve tested on this TV were more responsive than any we’ve experienced all year. Even though the picture quality may be imperfect, it is the best option we’ve found if your priority is to get rid of lag when playing games.

LG UM7300 audio quality

The UM7300 has two 20-watt speakers inside to provide two-channel sound. Furthermore, it doesn’t get very loud, and the lack of a subwoofer is noticeable in its wimpy bass.

I enjoyed listening to the dialogue between boxers and coaches in Creed II, but the fight itself – with its roaring crowd and a few low-end sounds like the impact of punches – lost a lot of its impact. Despite the clear and distortion-free sound quality, even at higher volumes, it was hard to distinguish the Rocky theme song samples that played during the fight.

LG UM7300 smart features

UM7300 does not compromise in any way when it comes to the smart TV experience. Thanks to its slick navigation and decent app selection, LG’s webOS is one of our favorite smart TV platforms. There is a wide variety of streaming services in the app store, so you’ll be able to browse everything from Netflix to Hulu to Pluto TV and YouTube TV.

With ThinQ AI features, you can also control everything with voice commands, using Google Assistant to access information online, such as stock quotes and weather reports.

With LG’s addition of Amazon Alexa’s voice assistant in 2019, voice interaction has expanded a bit more. As a result, it is one of the few TVs that let you utilize Alexa without pairing a separate Alexa-enabled device (like the Amazon Echo Dot).

Also in webOS 5, you can make a TV become your central hub of a connected home with a software tool called Home Dashboard. You are able to view who is at the door and adjust the mood lighting from your TV, no matter what smart products you are using. From your smart thermostat and laundry machine to your video doorbells and connected lightbulbs.

LG UM7300 remote control

As with LG’s top models, such as the LG C9 OLED, the LG Magic Remote is the same on the UM7300, along with the navigation features we’re used to seeing. The Magic Remote lets you wave your remote to move the cursor on-screen, making it possible to navigate using point-and-click, one of the most intuitive experiences on a smart TV.

In place of the enter button on competitor remote controls, this ring-shaped directional pad features a scroll wheel that can be clicked. We wish other manufacturers would also add scrolling as you move through Netflix recommendations and YouTube videos, and it’s a small but very important touch.

You will be able to use the TV’s ThinQ AI voice assistant as well as Google Assistant when pressing the microphone button on the remote control. When you’re using Amazon Alexa, you need to hold down the Amazon Prime button until the microphone is activated. The workaround seems awkward, but it’s not too difficult if you remember what button to press.

Pros Cons
Motion-control remote Poor motion handling
Excellent smart TV features Unimpressive black levels
Wide viewing angles Limited HDR support
Strong brightness levels


A 4K smart TV is the most basic LG model, and the LG UM7300 is no exception. The LG UM7300 is all about the price, with its simple design, mediocre performance, and limited HDR support. Based on the price alone, it’s doing just fine in the sales department since it consistently shows up on bestseller lists from retailers like Amazon and Walmart. Our money, on the other hand, has far more to do with value than the dollar amount printed on the label.

In our opinion, the Vizio M-Series Quantum offers better color and dynamic range at a similar price point, thanks to a quantum-dot display that boosts picture clarity and brightness. While the LG UM7300 offers a more robust smart TV experience than the Vizio, if streaming apps and smart home features are what you really need in a TV, this is a decent option, so long as you don’t mind the picture quality imperfections.
