- Connect the Transmitter (TX): Plug the HDMI connector of the OREI Transmitter dongle into the HDMI output port of your source device (laptop, PC, game console, media player).
- Power the Transmitter (TX): Connect a Micro USB cable (not always included, but often required for power) to the transmitter's power input and to a USB port on your source device or a USB power adapter. The power indicator light on the transmitter should illuminate.
- Pairing: The transmitter and receiver are pre-paired from the factory. Once both units are powered on and connected, they should automatically establish a connection. The "Pairing" indicator on the receiver will show connection status.
- Display Output: Select the correct HDMI input on your display device. The signal from your source device should now be wirelessly transmitted and displayed.
Important Note: For optimal performance, ensure a clear line of sight between the transmitter and receiver. Obstructions such as walls, furniture, or other wireless interference can reduce the transmission distance and signal quality.
