After you change the screen resolution, desktop icons move.

mChanging the screen resolution affects the display of information on your screen. The operating system may automatically reposition icons after you change the screen resolution.

The screen freezes.

mIf you are using both Energy Saver and a screen saver program, the screen saver program may be conﬂicting with Energy Saver. Turn off either the screen saver program or Energy Saver and restart your computer.

The light on the front of the monitor is flashing.

On some Apple ﬂat panel displays, the power light can display a series of short ﬂashes when an error has been detected.

mIf you see a repeating sequence of three short ﬂashes, the monitor is detecting input in the wrong video format. Check that your monitor is compatible with your graphics card and that you’ve installed the correct monitor software, if your monitor came with installation software.

mIf you see a sequence of two short ﬂashes and a long ﬂash, the monitor is detecting a problem with a backlighting lamp. Contact an Apple-authorized dealer or service provider.
