This automated test verifies that kernel-mode video drivers succeed in attempts to set gamma ramps.
This test is a basic test of Longhorn Display Driver Model (LDDM) gamma-ramp functionality. It sets gamma ramps by using Graphics Device Interface (GDI) and kernel-mode entry points for the operating system. Drivers must not fail during this process.
