You install a Windows Vista Service Pack on a computer that uses multiple monitors. Then, the custom display settings may revert to default display settings. The custom display settings that revert may include the following settings:
  • Default monitor choice setting
  • Monitor position setting in a multi-monitor configuration
  • Monitor display size setting
  • Monitor update setting (monitor refresh rate) and video adapter update setting (video adapter refresh rate)


This issue occurs because certain device drivers are reinstalled to correctly service the underlying components during an installation of a Windows Vista service pack. Therefore, certain customized display settings may be reset to their operational default settings.


To resolve this issue, reset the custom display settings on the computer. To do this, follow these steps:
