It is important always to use secure coding techniques while you work with display drivers.

Best Practices
Validate information from PSL calls
Display drivers that reside in the Graphics, Windowing, and Events Subsystem (GWES) processing space can potentially impact all of GWES. There is no control over what processing will be attached to the portions of a display driver that resides within GWES; therefore, these type of drivers should implement parameter validation algorithms on all information that comes into them from protected server library (PSL) calls.
