How to play a slideshow to projector from iPad

This tutorial is about how to connect your iPad to a projector(such as projector in a campus Smart Room or business conference room ), and play your slideshow on a  bigger screen from iPad. When put your slideshow on a projector, you can showcase your photo presentation to many people in a room.

1. Create a slideshow with photos and music on iPad

So what app you can you use to make a slideshow presentation?  Photo Slideshow Director HD is the answer. It allows you to create stunning slideshows with photos and music in minutes. The iPad slideshow app also provides kinds of effects, such as dynamic transitions and pan & zoom effects, themes. You can edit and fix your slides with its powerful photo editor. Text adding feature is included to enable you to express your feeling.

2. Save the slideshow to your iPad Camera Roll

After personalizing the slideshow, you need to save it to iPad Camera Roll as a video. Touch the Export icon and select  Photo Library from Share Movie to list. The app will begin encoding and saving the slideshow to Camera Roll in mp4 (or mov)  format.

3. Connect iPad to a projector

The projector in a typical meeting room or classroom has a VGA connector. We need to use an adapter to convert the HDMI signal that comes from an iPad to  the VGA signal needed to go into the projector.
You can use Apple VGA Adapter to connect your iPad to a projector. Apple VGA Adapter can mirror whatever on your iPad or iPhone 4S screen — apps, presentations, websites, and more — on your VGA-equipped TV, display, projector, or other compatible display in up to 1080p HD. You can purchase it from Apple Store.

•     Plug the dock connector into your iPad
•     Plug the VGA connector into the VGA port on your projector
•     Set your projector to the VGA input
•     Now your iPad will display on the projector screen.

Note: If the slideshow includes music, you’ll need to connect your iPad using the minijack (or headphone jack) to an external amplification system to hear the audio.
To connect the iPad to a projector with HDMI input use an HDMI cable and Apple Digital AV Adapter.

If the projector has both VGA and HDMI input, it is better to choose a HDMI cable. Because with HDMI cable, video and audio can pass together to your projecting device. This is crucial when your slideshow includes music.

4. Play a slideshow on projector from iPad

Now your iPad seems like a remote control. You operate on it and whatever shows on iPad will also show on projector screen.
Go to your iPad Camera Roll and find the slideshow, then tap it to play. Then you can watch the slideshow on the bigger projector screen.
