Before rotating the monitor with a portrait viewing orientation, the display has to be rotated 90 
degrees.
Right-click the desktop and select 
Screen resolution from the popup menu. Select Portrait in 
Orientation, and apply the setting.
Depending on the operating system on your PC, different procedures should be followed to adjust the screen 
orientation. Refer to the help document of your operating system for details.
2. Fully extend the monitor and tilt it.
Gently lift the display up and extend it to the maximum 
extended position. Then tilt the monitor.
The monitor should be vertically extended to allow to rotate 
from landscape to portrait mode.
3. Rotate the monitor 90 degrees clockwise as

To avoid the edge of the LCD display hitting the monitor base 
surface while it is being rotated, do tilt and extend the monitor 
to the highest position before you start to rotate the display. You 
should also make sure there are no obstacles around the monitor 
and there is enough room for cables.
