 Position the mouse at the same height as your keyboard. Allow adequate space to
use the mouse comfortably.
 Arrange the display so that the top of the screen is slightly below eye level when
you’re sitting at the keyboard. The best distance from your eyes to the screen is up to
you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).
 Position the display to minimize glare and reflections on the screen from overhead
lights and nearby windows. If possible, use a tiltable display stand. The stand lets you
set the display at the best angle for viewing, helping to reduce or eliminate glare
from lighting sources you can’t move.
