After you change the screen resolution, icons move.
Changing the screen resolution affects how information can be displayed on
your screen. The display software may automatically reposition icons after
you change the screen resolution.
After you attached a new monitor to your computer, the new monitor’s screen is blank or
shows “garbage” or “snow.”
The computer may not have recognized the monitor. Try the following: Turn
off the computer and disconnect the new monitor. Start the computer with no
monitor attached. Wait a minute or so for the computer to finish turning itself
on. Turn off the computer again and reattach the new monitor.
The monitor does not go to sleep.
Some computers and video cards do not support the Energy Saver feature. See
the documentation that came with your computer and video card for more
information.
If you have a Power Macintosh 9500, you can get an upgrade to your software
that allows your monitor to work with Energy Saver. Call the Apple Service
and Support number found in the service and support information that came
with your computer.
When you use both Energy Saver and a screen saver program, the screen freezes.
The screen saver program may be conflicting with Energy Saver. Turn off
either the screen saver program or the Energy Saver control panel.
You see two resolution options labeled 640x870 (75 Hz).
If you’re using the Macintosh 24AC video card, you may see two apparently
identical resolution selections. The first option sets your monitor to display
millions of colors, and the second option sets your monitor to display 256
colors.
When you change resolutions, the monitor goes blank.
If your monitor is connected to the Macintosh 24AC video card, the monitor
may go blank for 15 seconds when you select a resolution that does not work
with your monitor. Try selecting another resolution.
