How do I set up second monitor

I'd like to set up a second monitor for day trading. I need more space for windows programs associated with trading. Is there a manual/program for something like this or can someone give me step by step instructions?

You guys are always my first call for information and I appreciate all that you do.

Thank you, wildbill
