Adjusting the Display

The Acrobat Swing Arm comes factory set to support 6kg displays. Adjust the arm to suit the weight of your
display as shown in the following steps:

H.1. Adjusting the Ball Joint Resistance

Depending on the weight of the monitor, it may
be necessary to make adjustments to the Ball Joint
Mechanism. If the monitor doesn’t hold its position or

is too resistant, adjust the four tension screws located
around the Ball Joint (see diagram on the right) using
the supplied 2.5mm Allen Key.

Recommended Viewing Distance / Height

B

Ergonomists recommend that the optimal position of your screen should be slightly below eye level.
When looking at the screen’s centre the user should have a downward visual angle of approximately
10°-20°. As a guide, the height (h) of your display should approximately be as follows:

1

Tall Male (Max): 560mm (22”) Tall Female (Max): 520mm (20

1

/

Short Male (Min): 368mm (14

2”) Short Female (Min): 356mm (14”)

For visual comfort, a viewing distance (d) between 500mm (19

/

2”)

1

/

2”) to 750mm (29

1

/

2”) is

recommended.

Angular adjustments to reduce reflection on your monitor should range between 5° forward tilt to 15°
backward tilt.

5°

HORIZONTAL SIGHT LINE (d)

15°

It is possible to control the amount of resistance in the
Pivot Head to suit your display.

To increase the resistance of the Pivot Head to suit
heavier displays, use the 5mm Allen Key supplied in the
Desk Clamp Box to tighten the interscrew in a clockwise
direction.

To decrease the resistance of the Pivot Head to suit
lighter displays, loosen the interscrew in an
anti-clockwise direction.

NOTE: It is recommended the Pivot Head be
left at the factory setting for best performance.

H.3. Adjusting the Swing Arm/Gas Strut Resistance

H.3.1. Depending on the weight of the monitor, it

may be necessary to adjust the arm. This can be
done by using the 5mm Allen Key supplied in the
Desk Clamp Box.

H.3.2. If the arm tends to automatically rise

or fall when the display is attached, it will be
necessary to make small adjustments to the gas
strut. (see diagram on the right)
