2.3 Detaching the arm/base (for VESA
wall mount)
The detachable arm/base of this monitor is specially designed for VESA wall
mount.
To detach the arm/base:
1. Have the front of the monitor face down on a table.
2. Loosen the four screws on the back of the monitor and remove the arm/base.
We recommend that you cover the table surface with soft cloth to prevent
damage to the monitor.
