Using Basic Projector Features
You can set up your computer for wireless projection and play audio through the projector's speaker system by connecting using Miracast.
Select the Miracast settings on your projector as necessary.
Press the Wireless button on the remote control to switch to the Miracast source.
Click the speaker icon on your computer's taskbar.
Click Cast.
If Cast is not displayed or another message is displayed, see the manual supplied with the computer.
Select the projector's Projector Name from the list.
If you see the screen asking if you allow the projection using Miracast on the projector, check the device name displayed and select if you allow the projection or not.
It may take some time until the connection is established. While connecting, do not disconnect the projector's power cord. Doing so may cause your device to freeze or malfunction.
