14 How to assemble your monitor hardware
To rotate the display
1. Fully extend the monitor and tilt it.
Gently lift the display up and extend the stand to the maxi-
mum extended position.
If the monitor is locked at the lowest position, you have to
press Lock down / release button on the bottom rear of
stand to extend the stand to the maximum extended posi-
tion.
The stand should be vertically extended to allow the
monitor to rotate from landscape to portrait mode.
Then tilt the monitor.
2. Rotate the monitor 90 degrees clockwise as illustrated.
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.
