Adjusting
monitor
arm
tension:
If
you
are
installing
a
relatively
light
monitor,
the
tension
on
the
monitor
arm
may
need
to
be
adjusted,
by
turning
the
screw
in
the
picture
counter
clockwise.
A
heavier
monitor
may
require
tightening
of
this
same
screw.
A
properly
adjusted
monitor
arm
will
allow
the
monitor
to
remain
in
any
position
the
user
chooses.
