Setting refresh rate manuall in display options?

Question

hi all,
I have recently received a Dell 1908WFP monitor, which runs at a native resolution of 1440x900x75hz.
When i connect it to my macbook pro using the mini-display-port-to-VGA-connector, this resolution is detected fine.
When connecting with the DVI connector, the resolution 1440x900 is setup properly, but the vertical refresh rate is set to 60hz. In display preferences the option for 75hz is greyed out.
Is there a way to force the refresh rate to 75hz?
thanks,
lennard

Hmm, I think I'm missing something here but I just looked at GraphicsDevice.java and as far as I can see it doesn't check for refresh rates.
     * Returns the current display mode of this
     * <code>GraphicsDevice</code>.
     * @return the current display mode of this graphics device.
     * @see #setDisplayMode(DisplayMode)
     * @since 1.4
    public DisplayMode getDisplayMode() {
        GraphicsConfiguration gc = getDefaultConfiguration();
        Rectangle r = gc.getBounds();
        ColorModel cm = gc.getColorModel();
        return new DisplayMode(r.width, r.height, cm.getPixelSize(), 0);//REFRESH_RATE_UNKNOWN = 0; ??
     * Returns all display modes available for this     
     * <code>GraphicsDevice</code>.
     * @return all of the display modes available for this graphics device.
     * @since 1.4
    public DisplayMode[] getDisplayModes() {
        return new DisplayMode[] { getDisplayMode() };
    }Or have I read this wrong?
