The LG OLED77C51LA television features a 77-inch OLED evo panel with a 4K UHD resolution of 3840 x 2160 pixels. The self-lit pixels provide pixel-level dimming, which contributes to absolute black levels and high contrast ratios. Image processing is managed by the α9 Gen 8 AI Processor 4K, which uses AI-based algorithms for upscaling content and optimizing picture quality. The display supports multiple high dynamic range formats, including Dolby Vision, HDR10, and HLG, to render a wider spectrum of color and brightness. Its native 120 Hz refresh rate, combined with OLED Motion technology, is designed to reduce motion blur in fast-moving scenes.
This model operates on the webOS 2025 smart platform, providing access to a range of streaming applications and internet services. The system includes voice control functionality for hands-free navigation and search. The audio system consists of a 2-channel speaker setup with a total output of 40 watts and supports Dolby Atmos for object-based sound. Connectivity options are extensive, with four HDMI 2.1 ports that support features like eARC, three USB 2.0 ports, an optical audio output, and an Ethernet port. For wireless connections, the television is equipped with Wi-Fi 6 and Bluetooth 5.3.
