Overview

The LG 34BN770-B is a 34-inch UltraWide monitor built for professionals who need room to work. With a QHD resolution of 3440x1440 spread across a 21:9 aspect ratio, it provides roughly 33% more horizontal screen space than a standard widescreen display, making it ideal for spreadsheet-heavy workflows, video editing timelines, and side-by-side document comparison. The IPS panel covers 99% of the sRGB color gamut and supports HDR10, delivering vibrant, accurate colors with wide viewing angles that remain consistent whether you're looking at the screen head-on or from the side.

Productivity features are central to this monitor's design. Picture-by-Picture mode lets you display two input sources at their native resolution simultaneously, while Dual Controller allows a single keyboard and mouse to operate two connected PCs. The OnScreen Control software provides convenient access to monitor settings and screen-splitting presets directly from your desktop. The height and tilt adjustable stand keeps the display ergonomically positioned throughout long work sessions, and TAA compliance along with EPEAT Bronze certification make it a straightforward choice for government and enterprise buyers with sustainability and sourcing requirements.
