4 Adjust the height tension screw so the raising and lowering forces are
equal. After the forces are equalized, turn the tension screw clockwise two
to four turns to slightly decrease the lifting tension.

1 inch (2.54 cm) below eye level.
Adjusting monitor tilt tension
To adjust your monitor’s tilt tension:
■ Adjust the tilt tension screw (on the top of the stand) so the monitor stays
in place when you let go. If the monitor changes its tilt angle when you
let go, turn the screw clockwise one complete turn to increase the tension.
Ergonomic guidelines
The recommended screen positioning is based upon the following guildelines.
These guidelines are based on available scientific literature and published
standards.
Screen height
The recommended screen height for displays (except in special circumstances,
such as for bifocal use) is that the top of the display should be set at or slightly
below (about 1 inch or 25 mm) your eye level while you are sitting in a
comfortable working posture. This guideline places the center of the screen at
an ideal 15° to 20° viewing angle for most desktop displays. If the display has
multiple users, the screen height should be easily adjustable to accommodate
each user’s height and preference.
Screen tilt
The screen should be tilted so your line of sight is perpendicular to the screen.
This angle creates the most consistent viewing distance when scanning from
the top of the screen to the bottom. You may need to adjust lighting to avoid
screen glare when the screen is tilted upward.
