How to use

Use the on-screen display (OSD) to adjust brightness, color mode and input selection. For a wired network connection, attach an Ethernet cable to the RJ45 port; when using USB-C docking, the monitor can provide network access and peripheral connectivity to a connected laptop. Position applications across the wide screen area for more efficient workflow and configure operating system display settings to match the native WUHD resolution and refresh rate.

Usage recommendations

For color-critical work, calibrate the display with a hardware colorimeter and select an appropriate color profile in your operating system or creative applications. When using USB-C for power delivery, verify the laptop's power requirements to ensure adequate charging. To minimize eye strain during long sessions, enable a low-blue-light mode or adjust brightness to ambient lighting levels.
