4.1. Transmitter (TX) Unit

The TX unit connects to your source device (e.g., smartphone, tablet, laptop) via USB-C. It draws power directly from the connected device, eliminating the need for an external power supply for the transmitter. It supports Type-C charging for your source device while mirroring.

4.2. Receiver (RX) Unit

The RX unit connects to your display device (e.g., TV, projector, monitor) via HDMI. It requires external power, typically supplied via a USB Type-C cable connected to a power source or a USB port on your display.

5. Setup

The BDFFLY Wireless HDMI set offers a plug-and-play experience. Follow these steps for initial setup:

5.1. Connecting the Receiver (RX) Unit

1. Connect the USB Type-C power cable to the RX unit and then to a power source (e.g., a USB wall adapter or a USB port on your display).
2. Plug the RX unit directly into an HDMI port on your display device (TV, monitor, projector). If space is limited, use the provided HDMI extension cable.

5.2. Connecting the Transmitter (TX) Unit

1. Plug the TX unit into the USB Type-C port of your source device (smartphone, tablet, laptop). The TX unit will draw power from your device.

Once both units are connected, the display should automatically show the content from your source device. No Wi-Fi connection or app installation is required for the standard TX+RX pairing mode.

6. Operating Modes

The BDFFLY Wireless HDMI set supports two primary operating modes:

6.1. TX + RX Pairing Mode (Traditional Wireless HDMI)

In this mode, both the TX and RX units are used together. The TX unit connects to your source device, and the RX unit connects to your display. This mode offers direct, low-latency transmission without requiring Wi-Fi or additional software.

6.2. RX Unit Only Mode (Mirroring/Casting)

The RX unit can also function independently as a wireless display receiver. In this mode, you can mirror or cast content from your smartphone, tablet, or PC directly to the display by connecting only the RX unit to the display. This requires using your device's built-in screen mirroring or casting features.

6.3. Mirroring and Extension Display

When using the TX+RX pairing mode with a compatible laptop or PC, you can choose between two display options:

• Mirroring Mode: Duplicates your source device's screen onto the larger display. Ideal for presentations or sharing content.
• Extension Mode: Extends your desktop, allowing you to have different content on each screen. Enhances productivity for multitasking.

6.4. Performance and Range

The device utilizes 5GHz dual-band technology for stable and low-latency transmission, minimizing interference from other Wi-Fi networks. It supports Full HD 1080P at 60Hz and offers an ultra-low latency of approximately 0.06 seconds. The effective transmission range is up to 50 meters (approximately 164 feet) in line-of-sight conditions.
