LG 34WN780-B 34-inch UltraWide QHD IPS Ergo Monitor

The LG 34WN780-B combines an expansive 34-inch UltraWide display with a flexible ergonomic stand, making it well suited for professionals, creators, multitaskers and entertainment users.

Its UltraWide QHD resolution of 3440 × 1440 and 21:9 aspect ratio provide significantly more horizontal workspace than a conventional 16:9 monitor. This allows users to work with multiple windows, applications, documents or editing timelines simultaneously without constantly switching between screens.

The IPS panel provides wide 178-degree horizontal and vertical viewing angles, while the 300 cd/m² typical brightness and 1000:1 typical contrast ratio deliver clear and detailed visuals. The monitor supports an sRGB 99% colour gamut and comes factory colour calibrated, making it suitable for colour-focused work and everyday content creation.

For entertainment and gaming, the LG 34WN780-B supports HDR10 and AMD FreeSync technology. Its 75Hz refresh rate and 5ms GtG response time help provide smoother on-screen movement and responsive performance.

One of the key features of this monitor is its Ergo Stand. It supports extension and retraction, swivel, height and tilt adjustments, allowing users to position the screen according to their preferred working posture. The stand supports up to 130 mm of height adjustment, ±280° swivel and ±25° tilt.

Connectivity includes two HDMI ports, one DisplayPort, two USB 3.0 downstream ports, one USB upstream port and a headphone output. Built-in speakers with MaxxAudio provide integrated audio, while Dual Controller and OnScreen Control add convenience for multi-device and display management workflows.
