mIf you have more than one monitor attached to your computer, the monitors may interfere with one another. Move the monitors farther apart or set the monitors at an angle, so their screens are close and their back panels are farther apart. If you still see flickering after moving the monitors more than 16 inches apart, contact an Apple-authorized dealer or service provider.

mIf you are using a video card that has a very low refresh rate (below 60 hertz), the monitor may flicker. You may be able to change the refresh rate for the card. See the documentation that came with your video card for more information.

No colors appear on the screen.

mMake sure that the number of colors is set correctly in the Control Strip or control panel. See “Using the Control Strip” in Chapter 2, and see the on- screen help that came with your computer.

mTry changing to another resolution. See “Changing Screen Resolution” in Chapter 2.

mAdjust the horizontal or vertical size of the picture. See “Adjusting the Size of the Picture” in Chapter 3. (Keep in mind that if you adjust the horizontal or vertical size of the picture, you may have to adjust it again if you change resolutions.)
