- Update the monitor driver from the Device Manager Property page.
- Update the monitor driver programmatically by using the UpdateDriverForPlugAndPlayDevices API. For more information about using the API, refer to the Microsoft Windows 2000 Device Driver Kit (DDK) documentation.
The behavior described in the preceding paragraph also depends on the way the video driver is installed. Consider the following two scenarios, where you observe the failure in one case, and a successful installation in the other:
- Scenario 1
Install the video drivers with the video driver started. In this case the monitors are not detected properly. Note that a restart prompt did not appear after the installation of the video drivers. This is the situation that was described previously. When you start the Video device, the installation code checks to see if it has any children (monitors here) that are marked with the capabilities of RAW and SILENT. If true, it installs the NULL driver upon finding no suitable hardware ID match. This results in the warning message.
- Scenario 2
Install the video drivers with the video device not started. In this case, the system provides a restart prompt. The video device has been started after the computer was restarted, and the monitors are detected correctly as "Plug And Play Monitors". In this case, when you restart the computer, the monitor is installed by the server side device installer code, which has different logic than the client side installer (that checked for raw and silent capabilities as in Scenario 1). The server side installer finds the best rank matching id assuming it is digitally signed and uses that. It does not perform a check for the SILENT or RAW behavior like the client side. The Upgrade Wizard follows a different path than the RAW or SILENT capability detection. This server side install then finds the correct compatible ID match of *PNP09FF for the monitors that are not listed in Inbox, and you then see "Plug and Play Monitor" listed correctly in the Device Manager.
