Marketing Information

34" 21:9 UltraWide™ QHD | More Space for Multi-Tasking

The UltraWide™ QHD monitor screen (3440x1440 resolution, 21:9 aspect ratio) is great for work. It allows you to have multiple items open on your screen and visible all at once.

HDR10 | Detailed Contrast

HDR-compatible monitors display brighter whites and blacker blacks compared to SDR displays. HDR renders dark and bright areas of an image with many more details, which were indiscernible under the old standards.

Full Movement of Display | Easily Follow Your Eye Level

The enhanced flexibility of the Ergo stand offers expanded ergonomic adjustment of extend, retract, swivel, pivot, height and tilt as well as providing the ideal screen position for a more comfortable and sustainable user experience.

Clutter-Free Desk Setup | Fully Use Your Desk

The compact design takes up very little desk surface and also contributes to easier installation.

One Click Mount

C-Clamp & Grommet

Multi Ports | A Variety of Interface

Supporting HDMI, DisplayPort and USB 3.0

OnScreen Control | Control with a Few Clicks

You can customize the workspace by splitting the display or adjusting basic monitor options with just a few mouse clicks.

Reader Mode | Less Blue, Improved Visual Comfort

Reducing blue light to help lessen eye fatigue, Reader Mode creates a screen with a color temperature similar to paper and provides optimal condition for reading.

Flicker Safe | Care for Eyes

Flicker Safe reduces invisible flickering on the screen and provides a more comfortable working environment for your eyes.
