PowerPoint presentations are used by business people and organization leaders regularly to communicate information and make presentations to groups about initiatives, products and services. They can also be used by churches and even at family reunions to present slideshows or other important information at gatherings and meetings. Knowing how to project a PowerPoint presentation from your desktop or laptop computer onto a wall or screen is a critical final step in communicating prepared information to the appropriate audience.
Purchase or borrow a portable projector that you can use to display your PowerPoint presentation on a blank wall or screen. Set up your computer and projector on a table or even surface in the room where you will be making the presentation.
Make sure the power is off to both the computer and projector. Locate the VGA cable on the back of your computer and on the rear of the projector; look for a blue or other-colored connection point that has two rows of small dots with a slightly shorter row on top and one spot on either side for a small screw to thread into.
Connect the computer and projector to each other through the VGA ports with a VGA cable. Thread the small screws completely into the holes on each device. Plug in the computer and projector to an electrical outlet with their respective power cables. Turn on both devices.
Locate the input source button on the projector and press it until you see the option for “computer” or until you see your computer’s desktop image displayed on the wall. Press and hold the “Fn” or “Function” key on your computer keyboard and press the “F8” key twice to display your computer’s desktop image on both your computer screen and the wall where the projector is pointed. Release both buttons.
Browse to your PowerPoint presentation and open it. Click “View” from the top menu within PowerPoint and click “Show” to display the presentation on the screen to your audience.
Perform a practice run-through of your presentation. Examine the way the presentation displays on screen (or on the wall). Make sure the fonts are large enough to be easily viewed and make adjustments as necessary. Practice advancing through the slides by pressing the right button on your mouse every time you want to move to the next slide.
