Apple ColorSync Display - Manual (Page 17)

Note: After you set up and configure the monitor, adjust the image and
colors on the screen to match your environment. For example, in a bright
room, contrast is usually best set at maximum; in a dim room, lower
contrast is usually more comfortable. See Chapter 2, “Installing and Using
Apple Displays Software,” for more information about making screen and
color adjustments using Apple Displays software for Mac OS–based
computers. See Chapter 3, “Using Your Monitor With Windows-Based
Computers,” for information about onscreen controls for adjusting screen
image and color for Windows-based computers.
Connecting the monitor to your computer
Follow these steps to connect your monitor to your computer.
IMPORTANT Before you connect any cords or cables, make sure your computer
is turned off.
WARNING This equipment is intended to be electrically grounded. Your
monitor may be equipped with a three-wire grounding plug—a plug
that has a third (grounding) pin. This plug will fit only a grounded AC
outlet. This is a safety feature. If you are unable to insert the plug into
the outlet because the outlet is not grounded, contact a licensed
electrician to replace the outlet with a properly grounded outlet. Do not
defeat the purpose of the grounding plug!
