changing the setting for Multiple monitors

Another exercise 3.2 in my book explains how I can changed the settings for Multiple monitors. A multimonitor allows you to use two monitors on the computer at the same time. According to my book A+ complete study if a person were to give a presentation and would like to have a presenters view on their laptop LCD but need to project slideshow onto a screen, you might need to connect an external projector to the laptop. I found this exercise rather interesting, and these are the step that I went through to changing the settings to Multiple Monitors. You know at exercise 3.1 were we had to click on display setting links and we click on the advanced setting button there were two monitor icons 1 and 2 well you click on 2, check the extend the desktop onto this monitor box, click and drag the second monitor to what ever position that you want around the primary monitor, and finally while the second monitor is still selected, change the refresh rate and resolution. Thats how you change the settings for multiple monitors.
