ChangeDisplaySettings Vs GL_BUFFER_BITS

When I use the Windows function ChangeDisplaySetting with the option CDS_TEST (don’t really change the resolution) or UPDATE_REGISTRY (really change it this time), I don’t get the same buffer bit format (with glGetIntegerv function) than when I change the résolution directly in Windows display option panel.

(did I made myself clear ?..)

I thaught that I their is a registry that is not changed when using the windows functon, but changed when you do it “manually”, but I can’t get which one it is… any help ?
