HP Desktop and Notebook PCs - Sharing your Screen Using Miracast (Windows 8.1)

Miracast is a wireless technology that projects the image on your computer screen onto your TV screen, projectors, and streaming media players that also support Miracast. You can use this to share what you’re doing on your computer, present a slide show, or even play your favorite game on a larger screen.
Step one: Getting your devices ready
If your computer came with Windows 8.1 or Windows RT 8.1 installed you only need to confirm that your wireless display supports Miracast, before adding the wireless display to your computer to complete the connection and start projecting.
However, if you upgraded your computer from an older version of Windows, you need to make sure your computer supports Miracast and is ready to project. Also, if the display you want to project to does not support Miracast, you need to add an extra piece of hardware to it before you can start projecting.
Checking if your computer supports Miracast
Follow these steps if you upgraded your computer from Windows 7 or older.
  1. Move the mouse to the lower-right corner of the screen to bring up the Charms menu, and then click or tap Devices .
      note:
    If you are using a touchscreen, swipe in from the right edge of the screen to bring up the Charms menu.
  2. Under Devices, click or tap Project.
Updating your drivers
If you upgraded your computer from an older version of Windows, you should get the latest drivers available for your computer. There are two ways to get them.

Setting up a display that doesn’t support Miracast
If the device that you are projecting to does not support Miracast, then you need a Miracast adapter that plugs into an HDMI port on your display device. The adapter allows your computer to communicate wirelessly with the display device.
A variety of manufacturers offer Miracast adapters, such as the Actiontec ScreenBeam Pro Wireless Display Receiver and the NetGear Push2TV (PTV3000) Wireless Display Adapter. Follow the manufacturer’s instructions to connect the adapter.
Go to the Support and Drivers page on the HP website to check for updates the firmware on your adapter, search for your specific device, and then follow their instructions to download and install that firmware.
Step two: Adding the display to complete the connection
After your computer and display are ready to project wirelessly, you need to add the wireless display to your computer. HP recommends that you have both devices in the same room.
