Can You Connect an Android Tablet to a Projector?

Delivering a PowerPoint or multimedia presentation is one of the business world’s routine tasks. Usually, that means setting up your laptop and connecting it to the projector, with a VGA cable like the one that connects a computer to its monitor. However, some LCD projectors now have the option of wireless connectivity. This makes it possible to leave the laptop at your desk and use a lightweight Android tablet for presentations.
Hardware
There are two basic approaches to wireless projection. One uses Bluetooth technology to transmit data to the projector, while the other requires both the projector and tablet to connect to your existing network. NEC projectors such as the NP-54 and NP-64 are an example of the first approach, with the optional Bluetooth dongle inserted into their USB port. Your tablet must have Bluetooth support, which is standard on mainstream tablets such as the Google Nexus and Samsung Galaxy but might be omitted on some lower-cost models. Epson uses the network technique, manufacturing projectors with built-in Ethernet or wireless networking.
Using Bluetooth
To get started with Bluetooth, activate the Bluetooth feature on the projector. If your model has Bluetooth built in, there might be a button to push or menu selection to make. With the NEC, inserting the Bluetooth dongle into the USB connector activates the receiver. Once Bluetooth is active on the projector, tap the date on your tablet and choose “Settings” from the menu. Touch “Wireless & Networks,” then “Bluetooth Settings” and turn on your Bluetooth if necessary. Choose your projector from the list of available devices, and enter a PIN or passcode if prompted. At that point, you’ll be able to transmit to the projector.
Using Your Network
Epson and other manufacturers produce network-ready projectors that can be connected through an Ethernet port or by wireless networking. It’s accessed through Epson’s proprietary projection app, iProjection. For an Ethernet-connected projector, it’s a simple matter of launching the app, tapping “Projector” and choosing the correct device. If the projector is networked wirelessly, there are some extra steps. Press the “LAN” button on the projector’s remote, and it will display the network’s SSID and IP address. Tap “Settings” on your tablet, then “Wireless & Networks” and finally “WiFi.” From the available networks, select the one with the same SSID as the projector. Then launch iProjection, tap “Projector” and select the projector with the correct SSID and IP number.
