Microsoft has written Knowledge Base article Q179154 - Adding OEM Display Adapters to Windows NT Display Tool.
"This article discusses how to add OEM drivers to Windows NT so that the drivers appear in the list of available drivers when using the Display tool. It also discusses how to enable the ability to use the 'detect' button to automatically find the appropriate driver.
This article contains two sections. The first section is how to add the drivers so they appear in the list and can be installed manually. The second section is how to make them appear in the list and be detectable."
