Would either:
EnumDisplaySettings():
"The EnumDisplaySettings function retrieves information about one of the graphics modes for a display device. To retrieve information for all the graphics modes of a display device, make a series of calls to this function."
- Or -
IDirectDraw7::EnumDisplayModes() (sorry, no link):
"The IDirectDraw7::EnumDisplayModes method enumerates all the display modes that the hardware exposes through the DirectDraw object that are compatible with a provided surface description."
Give you the info you need ?
