If you have a Chromecast receiver, this is an easy way to connect your Android to your projector. First, you will need to set up with your projector through HDMI connections. Assuming that the two devices are on the same network, you can cast your screen to the projector using your Chrome browser to enable you to share your screen. This is a nice option when you are want to show photos or videos on your device, or for occasional use.
If, on the other hand, you are looking to use this in a traditional collaboration setting such as a classroom or a meeting room, then you may want to look at a wireless screen mirroring system to enable faster switching between presenters – or multiple presenters sharing the same screen.
