Chromecast is very good for watchig NetFlix or Youtube. Chromecast is to be installed in the HDMI port in the projector.

To use it, user download Chromecast app from Apple or Android store. After initial setup, cast button will be added to app such as Youtube or Netflix. With a click of the cast button, your favorite video or movies will be shown on the projector.
