Applies to: Windows 8.1Windows 8.1 EnterpriseWindows 8.1 Pro More

Symptoms


You may experience the following two symptoms on a high DPI device that is running Windows RT 8.1, Windows 8.1 or Windows Server 2012 R2:
  • Consider the following scenario:
    • You have a high-DPI Windows 8.1-based device that has the Intel Smart Connect (iSCT) feature enabled.
    • The device is not connected to any external displays.
    • The device is put to sleep (System Power State S3).
    • An iSCT update occurs. This usually occurs automatically about 15 minutes after the device goes to sleep.
    • You resume the device from sleep.
    In this situation, the device switches to 100% DPI until you restart it.
  • Consider the following scenario:
    • You have a high-DPI Windows 8.1-based device that rotates the screen based on device orientation.
    • The device has a lid.
    • The "Closing the lid" behavior is set to Do nothing.
    • You close the lid, and then you rotate the device to cause at least one screen rotation.
    • You open the lid.
    In this situation, the device briefly displays 100% DPI on the Start screen unexpectedly, and then changes back to the standard DPI.
