2 Click Personalize, and then Display Settings.
3 Change the Colors option and click OK.
For more information see Windows ® Help.
A message displays saying that there is a problem with your
display settings and that the adapter type is incorrect or the

computer’s internal display.
To change the display properties:
1 Right-click in a blank area of the Windows ® desktop.
2 Click Personalize, and then Display Settings.
