How to project wirelessly
If your laptop, tablet, or phone supports Miracast, you can connect and share whatever’s on your device’s screen on the Surface Hub without using cables.
The steps to connect wirelessly depend on what type of device you have. If you’re using a PC running Windows 8 or later, press Windows logo key + K on your keyboard, and select the Surface Hub you want to project to.
If you're using a device running Windows 8 or Windows 8.1 and it's your first time connecting, select Project and follow the on-screen instructions to add a wireless display.
If you’re using another type of device, follow the instructions for that device. If you’re not sure how, search the manufacturer’s support site for instructions (some good search terms to use are the make and model of your device, “Miracast”, and “project”).
If you’re having any connection issues, try projecting with cables.
How to stop projecting
To stop projecting, go to your device to end the connection. The steps for ending a connection are different depending on the device, but if you have a laptop or tablet running Windows 8 or later, press Windows logo key + K on your keyboard and select Disconnect. Or, if you’re done working on the Surface Hub, select End session—your device will be disconnected, and the content and other data on the Surface Hub will be cleaned up so it’s ready for the next person. It’s very important to make sure you email or save files you were working on before you end a session. For more info, see End your session.
