Display Driver Testing Tools
In addition to providing a debugger, Windows 2000 and later operating system versions provide the following tools for testing and debugging your display driver:
newdisp -- lets you dynamically reload your driver without rebooting the system. See NewDisp: Dynamic Reload of a Display Driver for details.
Slider control in Control Panel's Display program -- lets you dynamically change the accelerations that GDI will call in your driver. See Dynamic Change of Permitted Driver Accelerations for details.
