If you experience problems with your Apple display, try the troubleshooting steps below.
1. Try these simple procedures before contacting Apple for help.
Before performing any of the following steps, make sure your display is used with a compatible
computer and all software updates have been installed. Please also make sure your computer
is turned on, the display is plugged into an outlet, all the cables are connected properly to your
computer and display, and your computer is not in sleep mode.
If the screen doesn’t have an image:
• Check the cables and connectors again to make sure they are connected properly to your
computer and the display.
• Make sure your computer is turned on and is not in sleep mode. If your computer’s display is
closed, use the external keyboard or mouse to wake the computer from sleep.
• Reset the PRAM by restarting your computer while holding down the Command (x), Option, P,
and R keys until you hear the startup sound a second time.
If the screen is dim:
• Make sure the display brightness controls are set properly. Choose Apple () > System
Preferences and click Displays. Drag the Brightness slider to adjust the brightness.
• If the colors on the display are too saturated or not correct, you may need to calibrate your
display. Open Displays preferences, click Color, click Calibrate, and follow the instructions.
