Apple Macintosh PowerBook 190 Series - Manual (Page 138)

Built-in display
m Adjust the angle of the display to minimize glare and reflections from
overhead lights and windows.
m You may need to adjust the brightness and contrast of the screen when you
take the computer from one work location to another, or if the lighting in
your work area changes. The brightness (¸) and contrast (O) controls are
to the right of the display.
External monitor
If you use an external monitor, this suggestion may be helpful.
m If possible, arrange the monitor so the top of the screen is slightly below
your 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).
