Do you know Window 7 has built in feature to help setting up for a presentation? Well if you don’t know or haven’t heard then you can decide and manage connectivity to external display devices like external monitor, projector, or even a huge TV.Well setting up is pretty simple, just press Win key + P (this is know as presentation mode).

Now you will be able to see a small window come up with options like computer only, duplicate, extend, projector only. You can select the option as your requirement.

• Monitor only: This is normal setting.
• Duplicate: This means same display on the main pc will be duplicated on the external display/projector/TV.
• Extend: This option is especially for people who work on very large screen or who do multitasking works like engineers/designers etc.
• Projector only: This mode display will be only on external devices and computer screen will be blank.
