Dell 2300MP Calibration

Hi, i'm a first time poster
I own a Dell 2300MP, projecting on a 96 inch DIY screen made from blackout cloth from a local fabric store. The projector is shelf mounted and 17 feet away from the screen. I'm using VGA to Component (rgb) for DVD and HDTV.

Was wondering if anyone out there has the same projector and what settings (Brightness, Contrast etc..) are they using.

Thanks in advance.
