Detect Resolution Change

How do I detect when the user changes the color resolution?  I tried WM_DISPLAYCHANGE, but couldn't get it to work.  I also thought WM_SYSCOLORCHANGE might do the trick, but I'm not sure.

Does anybody know what I should use?

LRESULT CMyFrameWnd::OnDisplayChange(WPARAM wParam, LPARAM lParam)
{
    // cBitsPerPixel = wParam;
    // cxScreen = LOWORD(lParam);
