Overview

The LG 43UN7300PUF is a 43-inch 4K UHD smart TV designed as an affordable entry point into LG's smart TV ecosystem. It solves a straightforward problem: getting a sharp, well-connected 4K screen with a good smart platform without spending a premium. If you're upgrading from an older 1080p TV, setting up a secondary screen for a bedroom or office, or just want a reliable streaming hub, this is the kind of TV that quietly does its job well. The Quad Core Processor handles app loading, input switching, and upscaling smoothly — you won't be waiting around for Netflix to launch or for the settings menu to respond.

Build quality is typical for this price range — slim bezels keep the look clean, and at 17.9 pounds with the stand, it's light enough to mount on a wall without heavy-duty hardware. The 3 HDMI ports and 2 USB ports provide enough connectivity for most setups, and the webOS platform with the Magic Remote genuinely makes daily use more pleasant than the clunky interfaces on many budget TVs. The point-and-click cursor on the Magic Remote feels more natural than mashing arrow keys, and built-in Alexa adds hands-free convenience. Where you'll feel the budget positioning is in peak brightness and audio — a well-lit living room can wash out the picture, and the speakers are best described as functional. A simple soundbar transforms the experience. For a bedroom, office, or moderately lit room, it punches above its price.

Pros & Cons

👍 Pros

  • Real 4K resolution at 3840x2160 provides noticeably sharper detail than 1080p, especially on a 43-inch screen at typical viewing distances.
  • WebOS with the included Magic Remote makes navigating apps and settings feel faster and more intuitive than many competing smart TV platforms.
  • Built-in Alexa lets you use voice control for content search and smart home commands without needing an external speaker.
  • Three HDMI ports accommodate multiple devices without a splitter or constant cable swapping.

👎 Cons

  • Panel brightness is limited, which reduces the impact of HDR content compared to mid-range or premium LG models.
  • Only two USB ports (both 2.0), which limits peripheral connectivity and media playback options.
  • No Dolby Vision support — HDR is limited to HDR10 and HLG, so Dolby Vision content plays in standard HDR.
  • The built-in speakers are thin and lack bass, so a soundbar is practically a necessity for movies and music.

Frequently Asked Questions

Yes. The webOS platform comes with a built-in app store that includes Netflix, Disney+, Apple TV+, Hulu, YouTube, and most major streaming services. Apps load reasonably quickly thanks to the Quad Core Processor.
Yes. Alexa is built directly into the TV, and the included Magic Remote has a microphone button for voice commands. You can search for content, control playback, adjust volume, and control compatible smart home devices without a separate speaker.
The TV has 3 HDMI ports, so you can keep a game console, streaming stick, and soundbar (or Blu-ray player) connected simultaneously without swapping cables.
The Magic Remote is included with the 43UN7300PUF. It supports point-and-click navigation, scroll wheel, and voice control right out of the box.
The 43UN7300PUF supports HDR10 and HLG formats. While it handles HDR metadata, the panel brightness on this model is modest, so HDR content will look improved over SDR but won't deliver the same impact as higher-end LG models with brighter panels.
