Overview

The LG 55UB8500 is a 55-inch 4K Ultra HD LED television that combines high-resolution visually with smart TV functionality and 3D entertainment. Its 3840x2160 panel delivers four times the detail of standard 1080p, making it well-suited for 4K streaming content, Blu-ray playback, and detailed photo viewing. A native 120Hz refresh rate keeps motion smooth during sports broadcasts, action sequences, and gaming, reducing the blur and judder that lower refresh rates can produce. The edge-lit LED backlight with local dimming works to enhance contrast by reducing brightness in darker areas of the image.

On the smart TV side, LG's WebOS platform provides a clean, card-based interface for accessing streaming services, managing inputs, and browsing connected media. The included Magic Remote adds a point-and-click experience similar to using a mouse, which makes navigating menus and typing searches considerably faster than a traditional remote. For 3D content, the TV uses passive 3D technology with two pairs of lightweight, battery-free glasses included. The connectivity package is generous, with HDMI 2.0 and 1.4 ports, USB 3.0 and 2.0, component, composite, optical audio out, and an Ethernet port for wired network access. It is a feature-rich display that covers entertainment, gaming, and everyday viewing in a single package.
