Getting the desktop bit depth
Author
Anyone know how to get the bit depth of the screen (pref. a Win32 function)? I need to create a window D3D window, and it fails if the bit depth of the backbuffer is different from that of the screen.

I do this:
D3DDISPLAYMODE d3ddm;
if( FAILED( m_pD3D->GetAdapterDisplayMode( D3DADAPTER_DEFAULT, &d3ddm ) ) )
return E_FAIL;
then d3dmm.Format will be what you're after, so can just set the backbuffer format to the same.
look in the sdk for D3DFORMAT for the different types.

Hmm... thats what ive got, but i''d prefer a non-D3D way.
The reason being that i''ve got my D3D renderer in a DLL, and i''d prefer not to have a function GetDesktopBitDepth() just to eliminate modes that are different from the desktop bit depth if the window isn''t fullscreen.

i think something like GetDeviceCaps(NULL,BITSPIXEL); will return the bpp, but i''m not sure about getting the format.

Perfect! Thats what i was looking for! I was looking through GetSystemMetrics() but couldn''t find anything - now i know why.
