Arranging your workspace
usually 51 to 61 cm (20 to 24 in.), and position it so you can view it
without having to twist your body. Also position other equipment
you use regularly, such as the telephone or a mouse, within easy
reach.
Glare and lighting
Position the monitor to minimize glare and reflections from
overhead lights, windows, and other light sources. Even 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 might have to 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 moistened with a nonabrasive liquid glass cleaner.
Air circulation
Your server and monitor produce heat. Your server has one or
more fans that pull in fresh air and force 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 server and monitor so that nothing blocks the air vents.
Attention:
To allow for air circulation, be sure to maintain the following
minimum clearances around the server:
Ÿ
102 mm (4 in.) in the front
Ÿ
127 mm (5 in.) in the rear
