Ergonomic Stand

The specially designed ergonomic stand clamps to the edge of your desk to save desk space while allowing you to raise the screen up to 5″, extend it forward by 7″, and tilt it 25° up or down. It can also swivel the screen 280° left or right, making it possible to turn the monitor all the way around its base to share information with someone sitting next to or across from you. The clamp supports a maximum width of 3.5″ and the screen attaches to the monitor arm with a single click.

This monitor features a super-slim bezel design and supports an UltraWide 3440 x 1440 resolution, providing you with space to multitask and work on large projects. The 178° vertical and horizontal viewing angles allow you to see the screen clearly from almost any position.

Vivid Color

The 34″ In-Plane Switching (IPS) panel supports 16.7 million colors with HDR10 high-dynamic range, covering 99% of the sRGB gamut, delivering accurate and lifelike images.

Made for Multitasking

The dual controller works with the Onscreen Control software to let you view content from multiple sources at once in picture-by-picture mode configurations. You can seamlessly manage content across different devices using a single mouse and keyboard connected to the monitor’s USB ports.

Integrated Audio
