推荐答案

可以使用P/调用USER32.dll的设备上下文参考来执行此操作.看一下ChangeDisplayFunction和EnumDisplaySettings，在这里进行描述:

如果您是nvidia显卡的所有者，请查看
nvidia api，您需要P/调用NVCPL.DLL:

Hi,

it''s possible to do this with the Device Context Reference which P/Invokes to USER32.dll . Have a look into ChangeDisplayFunction and EnumDisplaySettings, described here:

http://msdn.microsoft.com/en-us/library/dd183411.aspx[

http://www.pinvoke.net/default.aspx/user32/ChangeDisplaySettings.html

http://www.pinvoke.net/default.aspx/user32/EnumDisplayDevices.html

if you are an owner of nvidia graphics card, have a look into
nvidia api, you will need to P/Invoke NVCPL.DLL:
