The AOC CU34B3E delivers an expansive 34-inch ultrawide viewing experience designed for productivity, entertainment and smooth everyday performance. Its 21:9 aspect ratio and 3440 × 1440 UWQHD resolution provide generous horizontal workspace, making it easier to work across multiple applications while enjoying sharp, detailed visuals. The 1500R curved VA panel wraps the wide display around your field of view for a more immersive viewing experience. With a 3500:1 static contrast ratio, 300-nit brightness and HDR10 support, the CU34B3E delivers rich visuals across work, multimedia and entertainment.

The three-sided frameless design creates a clean, contemporary appearance and is particularly useful when building a multi-monitor workspace. Connectivity includes one HDMI 2.0 port, one DisplayPort 1.4 connection and an audio output. The monitor also supports 100 × 100mm VESA mounting for compatible monitor arms and wall mounts.
