The most convenient way is wireless, as it does not require the purchase of additional cables. Modern projectors (for example, Xiaomi Mi Smart Projector 2 or Fengmi 4K) support Miracast, Wi-Fi Direct or DLNA protocols.

  2. On a Xiaomi smartphone, open Settings โ†’ Connections and Sharing โ†’ Screen Transfer.
  3. Select your projector name from the list of available devices.
  4. Confirm the connection on both devices (entry may be required) PIN-code).

If Miracast doesnโ€™t work, try Wi-Fi Direct: The advantage of this method is a more stable connection, but data rates may be lower.
