Lightweight and Durable Frame

Despite its 55-inch size, the TV maintains a lightweight profile. The use of high-grade composite materials makes the unit both durable and manageable for wall mounting or table-top setup.

Stand Design

The stand design is sleek and unobtrusive. It offers solid support and minimizes wobble. LG has prioritized stability with ergonomic spacing, making it compatible with most modern TV units and consoles.

Display Technology

4K Ultra HD Resolution

This TV delivers a resolution of 3840 by 2160 pixels, providing four times the detail of Full HD. Every frame is rendered with sharp edges, refined details, and outstanding texture, whether you’re watching movies, sports, or playing games.

IPS Panel

The IPS technology enhances the viewing angle, enabling consistent color and clarity even when viewed from the sides. This is ideal for large rooms or wider seating arrangements.

Color Reproduction

With support for over one billion colors, the LG 55UT80 reproduces images with remarkable vibrancy. Color gradients are smoother, and transitions appear more natural. You’ll notice deeper reds, greener greens, and brilliant blues without oversaturation.

HDR Support

High Dynamic Range support ensures that contrast and color are enhanced on a frame-by-frame basis. Bright scenes appear more luminous, and dark areas retain shadow detail without becoming washed out.

The LG 55 Inch 55UT80 supports HDR10 and HLG formats, allowing compatibility with most modern streaming content.

Picture Processor

α5 AI Processor 4K Gen6

At the heart of the LG 55 Inch 55UT80 is the α5 AI Processor 4K Gen6. This chipset uses deep learning algorithms to upscale lower-resolution content to near-4K quality. It also adjusts picture sharpness, color balance, and contrast dynamically based on scene composition.

AI Brightness Control

The processor senses ambient lighting conditions and automatically adjusts the screen brightness for optimum visibility. Whether it’s day or night, the picture maintains visibility without being harsh on the eyes.

Image Noise Reduction

The advanced processor reduces visual noise and smooths textures across all content types. This is especially effective when watching older or lower-quality content.

Audio System

AI Sound Pro

The AI Sound Pro feature analyzes content type and audio signal to deliver optimized sound output. Whether it’s a dialogue-heavy drama or a bass-rich action film, the audio adjusts dynamically.

2.0 Channel Stereo

The inbuilt speaker system includes two full-range speakers with a combined output of 20W. These speakers provide clear voice reproduction and moderate bass levels for an enjoyable audio experience.

Dolby Audio Support

The LG 55 Inch 55UT80 supports Dolby Audio processing, enhancing virtual surround effects. This allows viewers to experience more immersive soundscapes even without external speakers.

Smart Features

webOS Operating System

The TV runs on LG’s proprietary webOS platform. Known for its clean interface and fluid navigation, webOS allows users to quickly access apps, settings, and content with minimal lag or delay.

App Store and Preinstalled Apps

The TV supports a wide range of preinstalled apps, including Netflix, YouTube, Prime Video, and Disney Plus. Additional apps can be downloaded from the LG Content Store, which offers streaming, fitness, education, and productivity categories.

Voice Control

With integrated support for LG ThinQ AI, Google Assistant, and Amazon Alexa, the LG 55 Inch 55UT80 allows users to control the TV using simple voice commands. You can change channels, adjust volume, search for content, or even control smart home devices.

Screen Sharing and Casting

With screen share features like Miracast, AirPlay 2, and WiDi, the TV can mirror content from smartphones, tablets, and laptops. This makes it easy to display personal photos, documents, and presentations.

Gaming Performance

Game Optimizer

The Game Optimizer dashboard gives users access to game-specific settings like black stabilizer, refresh rate status, and input lag adjustments. This ensures the best possible performance depending on the game genre.

Low Input Lag

The LG 55UT80 is designed with reduced input lag in game mode, providing faster responsiveness during gameplay. This is beneficial for console gamers who value reaction time.

Auto Low Latency Mode (ALLM)

With HDMI 2.0 and support for ALLM, the TV detects when a gaming console is connected and automatically switches to low latency mode to reduce delay between input and screen response.

Connectivity Options

HDMI Ports

The TV includes three HDMI 2.0 ports that support 4K video and audio return channel (ARC) for compatibility with most media devices, including soundbars, game consoles, and Blu-ray players.

USB Ports

There are two USB ports available for media playback, firmware updates, and connection to external storage. The USB ports support FAT32 and NTFS formats.

Ethernet Port

The wired LAN port allows for stable internet connectivity, especially useful for streaming high-definition content without buffering.

Optical Audio Output

This port allows users to connect the TV to external audio systems using an optical cable, delivering high-quality digital sound output to soundbars or AV receivers.

Bluetooth and Wi-Fi

The LG 55 Inch 55UT80 supports Bluetooth 5.0 for wireless audio connections and accessories. Dual-band Wi-Fi (2.4GHz and 5GHz) ensures stable and fast internet performance.

Remote and Control

Magic Remote Compatibility

The TV supports LG’s Magic Remote, which allows for point-and-click navigation, voice search, and scroll wheel operation. It streamlines interaction and makes using smart features more intuitive.

Simplified User Interface

The updated webOS interface groups content by genre, app, and usage patterns. This predictive recommendation system offers suggestions based on viewing history and time of day.

Energy Efficiency

Energy Saving Mode

LG includes eco-friendly features such as auto power-off, display dimming, and intelligent brightness control. These reduce power consumption without compromising user experience.

Power Consumption

Under typical usage, the TV draws moderate power, thanks to its LED backlight and efficient processor. In standby mode, the consumption is minimal, further adding to its eco-conscious design.

Installation and Mounting

Wall Mount Support

The LG 55 Inch 55UT80 supports standard VESA wall mounting options, making it compatible with most third-party brackets. Wall mounting allows for a clean setup and better space utilization.

Included Accessories

In the box, users will find the standard remote, power cable, quick setup guide, and stand components. Optional accessories like the Magic Remote may be sold separately.

Display Performance in Different Environments

Daylight Viewing

Thanks to its high peak brightness and IPS panel, the LG 55UT80 performs very well in bright rooms. Natural daylight or artificial lighting does not significantly wash out the image. Reflection handling is also impressive due to its semi-gloss screen finish, which minimizes glare.

Night Viewing

In low-light or dark rooms, the TV adapts using AI Brightness Control. The LED backlighting adjusts to offer deep blacks and clear highlights. However, because it uses a standard LED panel and not OLED or Mini LED, true black levels may be slightly elevated.

Wide Angle Viewing

The wide viewing angle offered by the IPS technology ensures that picture quality and color accuracy remain consistent, even when watching from the sides. This is ideal for group viewing settings like living rooms or offices.

Color and Contrast Capabilities

Dynamic Tone Mapping

Dynamic tone mapping works frame-by-frame to optimize contrast and detail in both bright and dark areas. Scenes with high contrast, such as nighttime cityscapes or sunsets, are rendered with impressive precision and color layering.

True Color Accuracy

With LG’s advanced color tuning and factory calibration, the TV delivers out-of-the-box color accuracy that’s very close to industry standards. This makes it suitable not only for everyday entertainment but also for content creators who may need color fidelity.

Black Stabilization

While it does not use local dimming, LG integrates black level enhancement to maintain shadow details. This helps in scenes with a lot of dark areas, where details could otherwise get crushed into solid black.

HDR Technology In-Depth

HDR10

HDR10 is the most widely adopted format for HDR content. It is used by most streaming platforms and 4K Blu-rays. With support for HDR10, this TV enhances static metadata to bring deeper contrast, brighter highlights, and a wider color spectrum.

HLG Support

Hybrid Log Gamma (HLG) is used primarily for HDR broadcasts. With HLG support, the LG 55UT80 is ready for future HDR television broadcasts or streaming services that use this format, ensuring longer product relevance.

Lack of Dolby Vision

It’s important to note that the TV does not support Dolby Vision. For some users who stream heavily from Netflix or use Dolby Vision-capable players, this could be a limitation. However, the processor still applies advanced tone mapping to non-Dolby content.

Upscaling and AI Enhancements

AI 4K Upscaling

Lower resolution content such as HD or SD channels is intelligently upscaled by the α5 AI Processor. It fills in details using contextual awareness and edge detection, making 720p or even DVD-quality content appear noticeably sharper on the 55-inch screen.

Face and Object Enhancement

The AI engine can detect faces and key objects within a scene and adjust clarity and contrast specifically for them. This results in clearer outlines, better texture, and more life-like representation of people and items.

AI Picture Mode

AI Picture Mode selects the best picture settings based on content type. For example, when watching animated movies, it prioritizes saturation and brightness. For documentaries, it enhances detail and color realism.

Audio System Capabilities Expanded

Sound Configuration

The LG 55 TV includes a 2.0 channel audio setup with dual downward-firing speakers. Each speaker outputs 10W, bringing the total output to 20W. This configuration is ideal for medium-sized rooms, offering clarity without distortion.

Virtual Surround Sound

LG’s Virtual Surround Plus simulates a wider soundstage, giving the impression of multidirectional audio without physical speakers placed around the room. This adds immersion to action sequences and music.

Voice Clarity

Dialogue enhancement features ensure that speech remains crisp, even during noisy scenes. This is particularly useful for talk shows, dramas, or news broadcasts, where voice intelligibility is crucial.

Sound Sync

With LG 55 Sound Sync, users can wirelessly connect compatible LG soundbars or Bluetooth speakers for a clutter-free audio upgrade. Synchronization is nearly instant, ensuring no lag between video and audio.
