34-inch UltraWide IPS monitor
The LG 34BN670-B is a 34-inch UltraWide IPS monitor with a 21:9 aspect ratio and 2560 x 1080 resolution. It targets office workers and multitaskers who want extra horizontal space for side-by-side windows. The panel covers 99% sRGB and delivers 400 nits typical brightness with VESA DisplayHDR 400 support. A tilt, swivel and 150 mm height-adjustable stand lets users set a comfortable viewing position.
Suits single-screen workflows.
This monitor suits professionals who prefer one wide display over dual monitors for spreadsheets, timelines or coding. AMD FreeSync and 5 ms response time also make it viable for casual gaming. Buyers who need sharper text for detailed design work or want more vertical resolution should look at higher-density panels. The 16.7 million colour depth and 1,000:1 contrast ratio meet general productivity demands but fall short of reference-grade colour workflows.
2560 x 1080 resolution across 34 inches
The 2560 x 1080 pixel grid spreads across the 34-inch diagonal, giving a 0.312 mm x 0.310 mm pixel pitch that handles standard office scaling comfortably. Typical power draw is 33 W, rising to 42 W maximum, with sleep below 0.5 W. Two HDMI ports and one DisplayPort connect multiple sources, while built-in speakers with MaxxAudio cover basic audio. HDR content peaks at 500 nits, though the 1,000:1 contrast ratio limits highlight depth in dark scenes.
