This article will show you how to best watch Netflix movies on your projector, even when you don't have WiFi.
How to access Netflix on portable projectors?
If you have access to a Wi-Fi network, the easiest solution is to connect the projector to a media player. As long as the projector has an HDMI port, you can connect any media streaming device to the projector. Since Android can connect to these devices wirelessly, playing Netflix on the projector becomes as easy as streaming it to your TV.
With the projector turned on, connect the media player to an open HDMI port and wait for it to turn on. The device may have an additional USB cable for power; this should also be connected to the TV or a wall outlet.
If the streaming device is not already configured to work with your Wi-Fi, set it up.
