For all other computers that are not listed in the table, try the following procedure to determine if the customer's configuration would benefit from the display upgrade:

1 Open the Monitors or the Sound & Displays control panel.

2 Locate the resolution area of the control panel.

If . . .

Then . . .

Only 640x480 is shown

The computer does not support either 800x600 or 832x624 and therefore would NOT benefit from the upgrade.

Both 640x480 and 832x624 are shown

The computer can support 800x600 resolutions but the system software may or may not make 800x600 available. Go to step 3.

If . . .

Then . . .

832x624 is shown

Go to step 3. If 800x600 cannot be accessed, upgrade to the Rev. B display.

3 Test the configuration as follows:

a Hold down the option key while clicking the Options button in the Monitors control panel. b If 800x600 is now available, select it and then close the control panel. c Restart to activate the new screen resolution. This configuration should NOT be upgraded since multiple screen resolutions are available.

832x624 is always shown as an option if the computer supports either 800x600 or 832x624 resolutions. However, system software may not always make the 800x600 resolution available.

Other computer configurations that generally should not be upgraded are the 630 series, Power Mac 6200, Quadra 660, 800, 840, 900, and 950 (check by using the procedure in Step 3 above).

After completing the steps, if you determine a display is eligible for upgrade, contact Apple Technical Support at (800) 919-2775.
