What Do I Need to Make My Projector Wireless?


If you're tired of lugging around multiple cables for your projector, use a wireless projector adapter to allow you to connect your computer to the projector without the need for cables. This also gives you the freedom to move your computer anywhere in the room, instead of being tied to the projector. To connect multiple computers at the same time to the projector, you'll also need a router.


  • A basic wireless projector adapter has two pieces: one that connects to the projector and one that connects to a USB port on your computer. The two pieces communicate data between the two devices, just as a cable would. These adapters start at about $120 as of the date of publication and can top $1,000 for more high-end models.


  • If you need to connect multiple computers to a projector, such as in an office with a ceiling-mounted projector, buy an adapter that lets you connect through your router. The adapter that attaches to the unit sends a wireless signal that your router can detect, allowing it to appear as a display option to any computer connected to that router's network.

Wired Plug

  • Unless you already own a battery-powered projector, it's typically not feasible to try to convert your projector to battery power. If your projector has a power cord that requires you to plug it into a wall outlet, plan to place the projector somewhere in the room that allows you to plug it in easily. The projector should stay stationary during your presentation anyway; it's more important that you and your computer be able to move around to interact with your attendees.

Wireless Mouse

  • For maximum mobility during your presentation, use a wireless mouse to interact with your computer. The wireless projector adapter lets you use your computer's mouse to progress to the next screen in your presentation. If you're using a wireless mouse, you can control the computer, and therefore the presentation, from anywhere in the room. Be sure to test your wireless mouse's range before your presentation in case the room is too big to allow you to control the computer from the far corners.
