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 (2 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.
For more information about power cords, see Chapter 1, “Important safety
information,” on page 1.
