I am frequently asked how to make a wireless presentation over Wi-Fi using the iPad and the Apple TV (HDMI output), when the projector, monitor, or SmartBoard display to be used has only an “old” style VGA input:
To do this, an HDMI digital to VGA analog converter is required [just using adapters without an electronic converter will not work]. There are a number of converters available on the market. The Linksys system that I use has been discontinued.
This converter has received good reviews and is sold by Apple in its own stores for $16.00 more.
1. Plug VGA cable into projector and turn projector on.
2. Plug other end of VGA cable into Converter box. If you are going to be using audio, plug mini plug audio cable into converter and the other end into speaker input.
3. Plug HDMI Cable from converter into Apple TV. Turn on Apple TV. Connect Apple TV to Wi-Fi Network
4. Turn on iPad. Select the same Wi-Fi network as you set for Apple TV
5. Push the iPad Home button twice– slide over to volume control where you should see the “Mirror” symbol. Turn Mirror “on” and your iPad should be Mirrored on the Projector.
- Test the setup on your home Wi-Fi system before relying upon it in public.
- Many computer monitors still have VGA inputs and you can use one to simulate a VGA projector for test purposes.
- Keep in mind, that for the wireless system to work, the Apple TV and the iPad must be on the same Wi-Fi network .
- Many networks have security features that will block the Airplay functionality of the Apple TV. To work around this, I always bring my own Wi-Fi to presentations- either using the hotspot on my iPhone or my MiFi card as the Wi-Fi source for the iPad and Apple TV. This way, I know the setup works and there are no surprises.
If you have questions regarding using the iPad for presentations, please comment publicly below , or send me an email at firstname.lastname@example.org. If your question is of general interest I may answer in a post, or if not will try to respond individually .
