Glare And Lighting; Air Circulation; Electrical Outlets And Cable Lengths - IBM NetVista A20 Quick Reference

Adjust the monitor so that the top of the screen is at, or slightly below, eye
level. Place the monitor at a comfortable viewing distance, usually 51 to 61 cm
(20 to 24 in.), and position it so that you can view it without having to twist
your body.

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Place the monitor at right angles to light
sources whenever 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 lighting changes
throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, place an
antiglare filter over the screen. However, these filters might affect the clarity of
the screen image; try them only after you have exhausted other methods of
reducing glare.
Dust compounds problems associated with glare. Clean your monitor screen
periodically using a soft cloth moistened with a nonabrasive, liquid glass
cleaner.

Air circulation

Your computer and monitor produce heat. The computer fan pulls in fresh air
and forces out hot air. The monitor lets hot air escape through vents. Blocking
the air vents can cause overheating, possibly resulting in malfunction or
damage. Place the computer and monitor so that nothing blocks the air vents;
usually 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air
is not blowing on someone else.

Electrical outlets and cable lengths

The location of electrical outlets and the length of device power cords and
cables might determine the final placement of your computer.
When arranging your workspace:
v Avoid the use of extension cords. Whenever 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 be accidentally dislodged.
For more information about power cords, see "Power cord notice" on page 43.
