Pico projectors are relatively simple to set up. First, determine what surface you’ll be projecting the image onto, place the projector at the right distance, and adjust the lens until the test image is focused. Depending on the media source, you'll want to plug in your micro SD card, USB drive, USB-C cable, or other wired connection, or activate the built-in wireless or Bluetooth transmitter, then pair it with whatever device you're using to stream media.
