- Select HDMI Input:
- On your TV or projector, select the correct HDMI input channel where the RX unit is connected.
- Pairing (if necessary):

- Mirroring/Extending Display: Depending on your source device's operating system settings, you can choose to mirror your screen (duplicate) or extend it (use the external display as a second monitor).

- No Display/Connection Failure:
- Ensure both the TX and RX units are properly powered via their respective USB Type-C ports.
- Verify that the correct HDMI input is selected on your TV or projector.
- If the units are not pairing automatically, perform the manual pairing process as described in Section 3, Step 4.

- Ensure there are no significant obstructions (walls, large furniture) between the transmitter and receiver.
