Description:

Initially installed with Vista display drivers for NVIDIA based graphics cards. This entry replaced the "NVIDIA Display Driver Service" or "NVIDIA Driver Helper Service" in XP - which was used in part to maintain overclocked display settings. In a GeForce 8800GT test system this isn't the case. Disabling it caused no ill effects but it's exact purpose isn't known - hence the "U" recommendation
