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.
