This feature can be very handy if you want to deliver presentation to a group of people in other room and you are on some other place. This way you not only will be able to control your slide show effectively but also use other application or browse if you need a handy information at that time

Like the same way we did for setting resolution at run time, we choose the same way

Settings for using two monitor for power point presentation

• Make a new slide show or open an existing one.
• Now click on SlideShow on the menu.
• In the slideshow menu, you will see Monitors which is the last item.
• In this you get a check box option Use Presenter View at the end
• Check on that and it will ask you to check for 2 monitors and configure it.
• This will also open a help which will give you a complete guidelines what more you can do on this.

This what the help says you can do

• You can use thumbnails to select slides out of sequence and create a customized presentation for your audience.
• Preview text shows you what your next click will add to the screen, such as a new slide or the next bullet in a list.
• Speaker’s notes are shown in large, clear type so that you can use them as a script for your presentation.
• You can black out the screen during your presentation and then resume where you left off. For example, you might not want to display the slide content during a break or a question and answer (Q and A) period.
• Thumbnails of slides that you can click to skip a slide or to return to a slide that you already presented.
• The slide that you are currently showing to the audience.
  

  

• The End Show button, which you can click at any time to end your presentation.
• The Black-out button, which you can click to temporarily darken the audience screen and then click again to show the current slide.
• Up Next, which indicates the slide that your audience will see next.
• Buttons that you can click to move forward or backward through your presentation.
• The elapsed time, in hours and minutes, since the start of your presentation.
• The speaker’s notes, which you can use as a script for your presentation.

Requirements for using Presenter view

• Make sure that the computer that you are using for the presentation has multiple monitor capability. Most desktop computers require two video cards for multiple monitor capability, and many laptop computers have multiple monitor capability built in.
• Turn on multiple monitor support.
• Turn on Presenter view
• However Power Point supports only up to two monitors. So if you are planning to choose more you might need to look for some other software.

If you want to connect two computers, try using KVM Switch

I am not sure on how it can be connected to monitors remotely but there should be some way. If anybody knows about it, do share it in comments.
