Overview

A 55-inch 4K OLED TV running LG's webOS platform, with Bluetooth, Ethernet, HDMI, USB, and Wi-Fi connectivity. It weighs 49.6 lb and measures 10.4 x 48.11 x 27.68 inches.

OLED panels light each pixel individually rather than relying on a backlight, which is the display technology this model is built around. The G4 series sits in LG's higher tier OLED lineup, paired here with the full webOS smart platform.
