NvAPIWrappr allows you to use the NVAPI functions directly (a.k.a. the low-level API) using the NvAPIWrapper.Native namespace. However, there is also a .Net friendly implementation of the NVAPI features (a.k.a. the high-level API) that can be used to minimize the complexity of your code and makes it more compatible with later releases of the library, therefore, I strongly recommend using these classes instead of using the native functions directly.

Currently, you can access different parts of the high level API as follow:

• Namespace NvAPIWrapper.Display: Display and Display Control API
• Namespace NvAPIWrapper.GPU: GPU specific API
• Namespace NvAPIWrapper.Mosaic: Mosaic API - Surround
• Namespace NvAPIWrapper.DRS: NVIDIA Driver settings and application profiles
• Namespace NvAPIWrapper.Stereo: Stereo specific settings and configurations
• Class NvAPIWrapper.NVIDIA: General Information And Methods

Please also take a look at the NvAPISample project for a number of simple examples.

This library is fully documented and this makes your journey through it as easy as it is possible with NVAPI.

• WindowsDisplayAPI: WindowsDisplayAPI is a .Net wrapper for Windows Display and Windows CCD APIs

• EDIDParser: EDIDParser is a library allowing all .Net developers to parse and to extract information from raw EDID binary data. (Extended Display Identification Data)

• HeliosDisplayManagement: An open source display profile management program for Windows with support for NVIDIA Surround
