4. Setup Guide
Follow these steps for a quick and easy setup:
- Connect Transmitter (TX): Plug the HDMI Transmitter (TX) into your computer's HDMI port. Connect a USB-A to USB-C power cable from a 5V/2A power source (e.g., laptop USB port, USB wall adapter) to the TX unit's USB-C port. Ensure the TX unit receives sufficient power for stable operation.
- Connect Receiver (RX): Plug the HDMI Receiver (RX) into an available HDMI input on your display device (e.g., TV, monitor, projector). Connect a second USB-A to USB-C power cable from a 5V/2A power source to the RX unit's USB-C port. Switch your display device's input source to the corresponding HDMI port (e.g., HDMI 1, HDMI 2).
- Automatic Connection: After both units are powered and connected, wait approximately 10 seconds. The TX and RX units will automatically pair and establish a connection. Avoid pressing any buttons during this initial pairing process.
- Re-pairing (if needed): If the units do not connect automatically or if you need to re-pair them, long-press the control button on both the TX and RX units simultaneously for 6 seconds. The units will enter re-pairing mode and attempt to establish a new connection.

5. Operating Modes
The BRAIDOL Wireless HDMI system supports various operating modes, primarily for PC connections:
- Copy Mode: In this mode, the content displayed on your source device (e.g., laptop screen) is mirrored exactly onto the connected display (e.g., TV). This is ideal for presentations, sharing videos, or collaborative viewing where identical content is desired on both screens.
- Extended Mode: This mode allows your connected display to act as an extension of your source device's screen. You can drag windows and applications from your primary screen to the extended display, providing more workspace for multitasking or private viewing.
6. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
- No Signal/No Video Output:
- Ensure both the Transmitter (TX) and Receiver (RX) units are receiving sufficient power (5V/2A). Check if the power indicator light is solid blue. If it's red, power is insufficient.
- Verify that the display device (TV, monitor) is set to the correct HDMI input source.
- Check the connection status on the RX unit's LED display. If it's blinking, the units are not connected. Try re-pairing them by long-pressing the control button on both units for 6 seconds.
- For PC connections, ensure your computer's display settings are not set to 'Computer Screen Only' or that the computer has not entered screensaver mode.
- Check for poor contact with the HDMI port on the computer or display. Try re-inserting the units or using the provided HDMI extender cable.
- Intermittent Connection/Signal Drop:
- Ensure both units are within the recommended transmission range (up to 100 feet/30 meters).
- Minimize obstacles (walls, large furniture) between the transmitter and receiver.
- Check for strong interference from other 2.4G/5G wireless devices. The system automatically switches frequencies, but extreme interference can still affect performance.
- Device is Hot:
- It is normal for the device to become slightly warm during continuous operation. If it becomes excessively hot, ensure it has adequate ventilation and is not covered.
