Glare
and
lighting
Position
the
monitor
to
minimize
glare
and
reflections
from
overhead
lights,
windows,
and
other
light
sources.
Reflected
light
from
shiny
surfaces
can
cause
annoying
reflections
on
your
monitor
screen.
Place
the
monitor
at
right
angles
to
windows
and
other
light
sources,
when
possible.
Reduce
overhead
lighting,
if
necessary,
by
turning
off
lights
or
using
lower
wattage
bulbs.
If
you
install
the
monitor
near
a
window,
use
curtains
or
blinds
to
block
the
sunlight.
You
can
adjust
the
brightness
and
contrast
controls
on
the
monitor
as
the
room
lighting
changes
throughout
the
day.
Where
it
is
impossible
to
avoid
reflections
or
to
adjust
the
lighting,
an
antiglare
filter
placed
over
the
screen
might
be
helpful.
However,
these
filters
might
affect
the
clarity
of
the
image
on
the
screen;
try
them
only
after
you
have
exhausted
other
methods
of
reducing
glare.
Dust
buildup
compounds
problems
associated
with
glare.
Remember
to
clean
your
monitor
screen
periodically
using
a
soft
cloth
as
directed
in
your
monitor
documentation.
Air
circulation
Your
computer
and
monitor
produce
heat.
The
computer
has
a
fan
that
pulls
in
fresh
air
and
forces
out
hot
air.
The
monitor
lets
hot
air
escape
through
vents.
Blocking
the
air
vents
can
cause
overheating,
which
might
result
in
a
malfunction
or
damage.
Place
the
computer
and
monitor
so
that
nothing
blocks
the
air
vents;
usually,
51
mm
(two
inches)
of
air
space
is
sufficient.
Also,
make
sure
the
vented
air
is
not
blowing
on
people.
Electrical
outlets
and
cable
lengths
The
location
of
electrical
outlets,
the
length
of
power
cords
and
cables
that
connect
to
the
monitor,
printer,
and
other
devices
might
determine
the
final
placement
of
your
computer.
When
arranging
your
workspace:
v
Avoid
the
use
of
extension
cords.
When
possible,
plug
the
computer
power
cord
directly
into
an
electrical
outlet.
v
Keep
power
cords
and
cables
neatly
routed
away
from
walkways
and
other
areas
where
they
might
get
kicked
accidentally.
