4K OLED Screen
The pixels of the Organic LED display are self-illuminating, adjusting independently, for true depth and colour gradation.

High Dynamic Range expands light, dark, and every colour in between for a picture that's closer to real life. This set supports multiple HDR formats including Dolby Vision.

a8 AI processor
LG’s intelligent processor, the brain of the TV, intuitively ensures optimised picture and sound quality, and delivers image enhancement through AI Super Upscaling. Plus, it upscales audio too for a more cinematic experience.
