Overview

The LG OLED55C4PUA represents the 2024 iteration of LG's popular C-series OLED lineup, and it continues to set the standard for what a mid-premium TV can deliver. At its foundation are over 8 million self-lit OLED pixels, each capable of turning completely off to produce absolute black levels and infinite contrast — a fundamental advantage over any backlit display technology. The result is picture quality with remarkable depth, where bright highlights and dark shadows coexist in the same frame without the blooming or light bleed artifacts common in LED/LCD panels. LG's Brightness Booster technology pushes individual pixel luminance higher than previous generations, and the α9 Gen7 AI Processor works continuously to optimize picture quality through AI Super Upscaling, intelligently analyzing and enhancing content regardless of its source resolution. Dolby Vision and Filmmaker Mode ensure that movies are displayed with the creator's intended color grading and motion handling, while Dolby Atmos through the built-in 2.2 channel speakers provides a spatial audio foundation that can be expanded with an external sound system.

For gamers, the C4 is exceptionally well-equipped. The 144Hz refresh rate paired with a 0.1ms response time delivers the fluid, ghost-free motion that competitive and fast-paced titles demand. Full HDMI 2.1 support across all four ports means 4K at 120Hz gaming is available from multiple consoles and PCs simultaneously, with NVIDIA G-Sync, AMD FreeSync Premium, and VRR keeping frame delivery smooth and tear-free. The Game Dashboard and Game Optimizer provide quick-access controls for adjusting picture settings, monitoring input lag, and switching between game genres — all without navigating away from gameplay. On the smart TV side, LG's webOS platform offers a clean, responsive interface with access to all major streaming services, and the webOS Re:New Program guarantees five years of updates so the software experience doesn't stagnate. The included Magic Remote with its point-and-click navigation makes browsing apps and settings faster than traditional directional remotes.
