Picture Quality

The UN7300PUF’s core attraction is its 4K resolution. Here’s a breakdown of its key visual aspects:

  • 4K Resolution: Enjoy crisp visuals and sharper details compared to Full HD TVs. Text appears clearer, and you might even notice subtle details you missed before in your favorite shows and movies.

  • Real 4K Display: Unlike some competitor TVs that might use tricks to upscale content, the UN7300PUF boasts a genuine 4K display panel. This ensures you’re getting true 4K resolution without any artificial enhancements.

  • HDR Compatibility: The UN7300PUF supports HDR10, a format that expands the contrast range for potentially more lifelike visuals with brighter highlights and deeper blacks. However, some reviewers note that the HDR implementation might not be the most impactful, particularly in terms of peak brightness.

  • Quad Core Processor: The LG UN7300PUF utilizes a quad-core processor to help enhance color, contrast, and clarity. This processing helps ensure smooth image reproduction and potentially reduces noise in low-light scenes.

Compared To Other TVs

The UN7300PUF sits in a competitive mid-range segment. While it delivers a decent 4K experience, some competitor TVs might offer features like higher peak brightness or more advanced picture processing technologies that can deliver a more impactful HDR experience. Additionally, some higher-end TVs might boast improved motion handling for smoother visuals in fast-paced content.

Brightness and Contrast

The brightness levels on the UN7300PUF are just average. While suitable for most viewing environments, the screen might struggle in very bright rooms. The contrast ratio is also decent but not outstanding. Blacks appear somewhat gray in dark scenes, especially when compared to TVs with features like local dimming that adjust backlighting dynamically for deeper blacks.

Here’s a point to consider: If you prioritize exceptional picture quality with top-tier brightness, contrast, and HDR performance, the UN7300PUF might not be your champion. Exploring pricier options with more advanced picture processing technologies might be a better fit.


LG UN7300PUF Alexa Built-in 4K Ultra HD Smart LED TV  design

The UN7300PUF embraces a minimalist aesthetic. The bezels are slim and stylish, creating a near bezel-less look that keeps the focus on the picture. The sleek stand offers sturdy support and a slight tilt functionality for optimal viewing angles. The back panel is made of plastic, which feels functional but not necessarily premium. Overall, the design prioritizes clean lines and a modern look that blends seamlessly into most living spaces.

Here’s a point to consider: The UN7300PUF might be a bit thicker than some ultra-slim TVs on the market. If wall mounting is your preference, be sure to check the depth specifications to ensure it fits your space requirements.

Sound Quality

Let’s face it, the built-in speakers on the UN7300PUF are just average. They lack depth and power, resulting in a somewhat thin and underwhelming audio experience. Dialogue can sound clear at moderate volumes, but bass is lacking, and action scenes might sound flat.

For an immersive movie or gaming experience, consider pairing the UN7300PUF with a soundbar or a home theater system. This will significantly enhance the overall audio quality and unlock the full potential of your entertainment. LG offers a variety of soundbar options that integrate seamlessly with the UN7300PUF, creating a unified and powerful audio solution.

Smart Features

The LG UN7300PUF runs on webOS, LG’s well-regarded smart platform:

  • User-Friendly Interface: webOS is known for its intuitive interface with a user-friendly layout. Apps and streaming services are neatly organized, making navigation and finding what you want to watch a breeze.
  • Vast App Selection: The UN7300PUF offers a wide selection of popular streaming services like Netflix, Hulu, Disney+, and countless others, along with games and additional apps.
  • Alexa Built-In: This is a major perk for those who prefer voice control. You can use Alexa to control the TV, search for content, or adjust settings, all with your voice.

Compared To Other TVs

webOS is a strong contender in the smart platform arena. However, some competitor TVs might offer additional functionalities or integrations specific to their own smart systems. For example, some TVs might have built-in support for Google Assistant or integrate more seamlessly with certain smart home ecosystems.

Here are some points to consider for Smart Features:

  • Learning Curve for Non-LG Users: If you’re not familiar with LG’s ecosystem, there might be a slight learning curve compared to more widely used platforms like Roku or Fire TV.
  • Limited Customization: webOS offers less customization compared to some competing platforms.


The LG UN7300PUF features a standard 60Hz refresh rate panel. While it delivers a decent viewing experience for most content like movies and TV shows, fast-paced scenes like sports or action movies might exhibit some motion blur. This can be a concern for gamers or viewers particularly sensitive to motion blur. The UN7300PUF lacks some motion processing features found on higher-end TVs that can help reduce blur. While some technologies might be included to try and minimize blur, they might introduce the “soap opera effect” where motion appears unnaturally smooth, which some viewers find undesirable.

Consider a TV with a higher refresh rate (120Hz or higher) for smoother motion handling in fast-moving content.

Gaming Features

The LG UN7300PUF caters to casual gamers with some basic features to enhance the experience. Game Mode pre-calibrates the picture settings for faster response times and a more responsive gaming experience. Additionally, ALLM (Auto Low Latency Mode) might be included on some models, helping reduce input lag for a faster response time between your controller actions and what appears on the screen. However, the UN7300PUF lacks some features that might be important for serious gamers:

  • Higher Refresh Rates: As mentioned earlier, the 60Hz refresh rate might not be ideal for gamers seeking the smoothest possible motion.
  • VRR (Variable Refresh Rate): This technology eliminates screen tearing, a visual glitch that can occur during fast-paced gameplay. The UN7300PUF doesn’t support VRR.
  • Advanced Gaming Modes: Some TVs offer dedicated game modes optimized for different game genres (FPS, RPG, etc.) for the best possible gaming experience. The UN7300PUF lacks such dedicated modes.

Durability and Build Quality

The LG UN7300PUF appears decently built with a plastic back panel and a sturdy stand. LG TVs generally have an average reputation for reliability, but longevity ultimately depends on usage and care. As with any TV, proper handling and avoiding extreme temperatures or environments will contribute to a longer lifespan.

Viewing Angles and Screen Uniformity

The viewing angles of the LG UN7300PUF are decent thanks to the IPS panel technology used in most models. Colors and picture quality remain fairly consistent when viewed from off-center positions. IPS panels offer wider viewing angles compared to VA panels, making them a good choice for rooms where multiple people might be viewing the TV from different angles.

In terms of screen uniformity, the LG UN7300PUF might exhibit some minor variations in brightness or color across the screen, especially in dark scenes. This is a common occurrence with most TVs, and its severity can vary between individual units. If uniformity is a major concern, researching user reviews and professional calibrations can help you determine if this is a widespread issue with the UN7300PUF.


LG UN7300PUF Alexa Built-in 4K Ultra HD Smart LED TV  inputs

The LG UN7300PUF comes equipped with a good selection of inputs, including:

  • Multiple HDMI ports (with some featuring HDMI 2.0 capabilities) for connecting streaming devices, game consoles, and cable boxes. HDMI 2.0 supports features like 4K resolution at 60Hz.
  • USB ports for connecting external storage drives or media players.
  • An optical audio output for connecting external sound systems.
  • An RF connector for connecting cable or antenna.

This selection of inputs allows you to connect all your essential devices to the UN7300PUF, ensuring you can enjoy your favorite content without needing extra adapters.

Overall Value

The LG UN7300PUF tempts budget-minded viewers with a genuine 4K display, Alexa built-in for voice control, and a user-friendly webOS smart platform loaded with apps. The price tag is attractive, but keep these potential shortcomings in mind:

  • Picture Quality Trade-Offs: While a true 4K panel delivers sharp visuals, average brightness and contrast hold it back, especially for HDR.

  • Motion Matters (or Not): The 60Hz refresh rate might cause motion blur in fast-paced scenes. Gamers beware, casual viewers might not find it bothersome.

  • Sound That Falls Flat: The built-in speakers are just average, likely requiring a soundbar purchase for an immersive audio experience (extra cost).

The Bottom Line

The LG UN7300PUF shines for casual viewers who prioritize a user-friendly smart platform with Alexa built-in, all at a budget-friendly price for a 4K TV. But if you demand exceptional picture quality, smooth motion handling, or superior sound without a soundbar, you might need to explore pricier options.
