Different display on laptop's screen and projector screen?

Question

I saw a lecturer using PowerPoint to present his lecture, however, I notice that although the projector only show the PowerPoint's slides, his laptop screen show different things. How can I do that?

Solution 1

I believe 'extending' your desktop should do the trick, as opposed to cloning. This is standard on nearly every system that supports more than one monitor.

Solution 2

After extending your desktop as @Journeyman Geek suggests, you need to enable dual monitor support in Powerpoint. If you are using Powerpoint 2007, you can do this by selecting the Slide Show tab on the ribbon, and select the monitor that you want to show the presentation on under Monitors.

Can you explain how to extend the desktop? I tried Google, but all solutions requires second monitor, but now I'm at home, and I don't have it.

Well, in his case, the projector acts as a second monitor. I suppose you may be able to simulate this with a second computer and zonescreen, but it is somewhat illogical to try to emulate a two monitor setup with one monitor

Some more possible solutions - Microsoft India, Split screen desktop (unreleased), Virtual Dimension (open source & developed) and ATI Hydravision (which i don't think they develop anymore)

The first seems the closest to what he needs, short of actually borrowing a monitor. He dosen't need virtual desktops, and hydravision is multiscreen management. He can quite easily do what he is talking about on any dual screen system

Assuming your using windows, the shortcut Win+P brings up the projector options, here you can toggle to "Extend" and you now have an extra desktop on the second display
