Overview

The LG 34WR55QC-B is a 34-inch curved ultrawide monitor with a WQHD resolution of 3440x1440 pixels, offering significantly more horizontal workspace than a standard 16:9 display. The curved panel wraps content around your field of view, reducing eye strain during long work sessions and providing a more immersive experience for media and gaming. HDR 10 support enhances contrast and color depth in compatible content, while the sRGB 99% color gamut ensures accurate color reproduction for creative and professional tasks. A 3000:1 contrast ratio delivers deep blacks and bright highlights for a visually engaging picture.

Connectivity is a key strength of the 34WR55QC-B. The USB Type-C port with 65W Power Delivery lets you connect and charge a laptop through a single cable, streamlining your desk setup. Additional inputs include 2 HDMI ports, DisplayPort, and 2 USB ports. Features like Picture-by-Picture mode, Auto Input Switch, and Dual Controller add flexibility for users managing multiple devices. The 3-side virtually borderless design keeps the visual footprint clean, and the tilt and height adjustable stand provides ergonomic versatility without requiring aftermarket mounting. AMD FreeSync, Black Stabilizer, and Dynamic Action Sync round out the gaming-oriented features for those who want smooth, responsive gameplay alongside everyday productivity.
