The LG OLED55C9 is a 55-inch Class (54.6" diagonal) 4K Ultra HD OLED television from LG's C9 Series. Powered by the α9 Gen 2 Intelligent Processor, it uses advanced AI-driven algorithms for upscaling, quad-step noise reduction, and frequency-based sharpness enhancement to bring any content close to native 4K quality.

The self-lit OLED panel features pixel-level dimming, producing absolute blacks and virtually infinite contrast with no backlight required. It supports 4K Cinema HDR with Dolby Vision, HDR10, and HLG, along with HDR Dynamic Tone Mapping Pro and Ultra Luminance Pro for highlight detail. True Color Accuracy Pro and Billion Rich Colors technology deliver wide-gamut, accurate colors across the entire screen.

Audio is handled by a 2.2-channel speaker system rated at 40W total output (including a 20W dedicated woofer) with full Dolby Atmos and DTS-HD decoding for an immersive three-dimensional soundscape. The TV runs LG's webOS smart platform with LG ThinQ AI, featuring built-in Google Assistant and Amazon Alexa for hands-free control, along with a full web browser and LG Content Store app ecosystem. The included Magic Remote offers point-and-click navigation, scrolling, and voice recognition.

Connectivity includes 4 HDMI 2.0 inputs with HDCP 2.2 (including eARC on HDMI 2 for next-generation audio return), 3 USB 2.0 ports, optical digital audio output, an Ethernet port, Bluetooth 5.0, and 802.11ac Wi-Fi. The panel measures 48.3" x 27.8" x 1.8" without the stand and supports VESA 300 x 200 wall mounting. It weighs 41.7 lbs without the stand and 50.7 lbs with the stand.
