That’s easy: however you’re watching Netflix now, just run an
HDMI cable from that device to your projector (you might need a Lightning-to-
HDMI or USB-to-
HDMI dongle if it’s a mobile device) and you’ll be in business.
If you want a more permanent setup, and don’t want to have to run a long
HDMI cable from your device to the projector, consider installing a Roku Streaming Stick or Amazon Fire TV Stick on one of the projector’s
HDMI jacks; you can use the USB port on the projector to power the stick.
