    Changing resolution

    Hi, I have an OpenGL program that has a menu allowing for changing of resolution. However, I cannot get it to change correctly (it seems to change res but the alignment is off the screen).

    I change the .dmPelsWidth and .dmPelsHeight to the new setting then call ChangeDisplaySettings. Do I need to resize the scene and do I have to resize the window? If so, does anyone know how?

    Thanks...

    Re: Changing resolution

    Have you tried calling glViewport after the resize?

    void glViewport(
    GLint x,
    GLint y,
    GLsizei width,
    GLsizei height
    );

    such as:

    void glViewport( 0,0,width,height );
