## Long description

The LG 34U511A-B is a 34" (86.4 cm) UltraWide WFHD (2560 × 1080) LED monitor with an IPS panel, slim bezels and a flat screen. It delivers a wider horizontal workspace than standard FHD monitors, supports VESA DisplayHDR 400 for improved brightness and contrast, and arrives factory color-calibrated with sRGB/ DCI-P3 coverage for accurate color reproduction. The monitor includes a built-in USB hub, 100×100 VESA mounting compatibility and a slim stand with tilt adjustment.
Advantages
The UltraWide 21:9 WFHD display increases usable horizontal screen space for more efficient multitasking and reduced window switching. The IPS panel provides wide 178° viewing angles and stable colors, while factory color calibration and 99% sRGB (typ.) coverage support consistent color accuracy. VESA DisplayHDR 400 enhances brightness and contrast for clearer HDR detail. Motion clarity is improved by the 1 ms MBR feature, and eye comfort is supported by Reader Mode and Flicker Safe. The slim stand minimizes desk clutter and the monitor also supports PBP/PIP and LG Switch software for flexible window management.
Suitable for
 Office multitasking and productivity work with multiple side-by-side windows
 Content review and color-aware tasks that benefit from calibrated color and wide color coverage

How to use

Usage recommendations
For best color accuracy, allow the monitor to warm up for 30 minutes before critical color work and calibrate with your preferred hardware calibrator if precise profiling is required. When multitasking, use LG Switch to arrange windows into up to six sections and enable PBP/PIP only when using multiple input sources.
