## Detailed Description

A list of all available video modes.

You can get a list via IrrlichtDevice::getVideoModeList(). If you are confused now, because you think you have to create an Irrlicht Device with a video mode before being able to get the video mode list, let me tell you that there is no need to start up an Irrlicht Device with EDT_DIRECT3D8, EDT_OPENGL or EDT_SOFTWARE: For this (and for lots of other reasons) the null device, EDT_NULL exists.
