3. Setup Instructions
The Llano Wireless Screen Mirroring Device is designed for simple, plug-and-play operation.
- Connect the Receiver: Plug the HDMI cable from the Llano Receiver Unit (the circular device) into an available HDMI port on your TV, monitor, or projector.
- Power the Receiver: Connect the power cable (usually USB) from the Receiver Unit to a USB power source (e.g., a USB port on your TV or a USB wall adapter). The device will power on, and you should see an indicator light (often blue) illuminate.
- Connect the Transmitter: Plug the Llano Transmitter Unit (the smaller dongle) into the HDMI or USB-C port of your source device (phone, tablet, laptop).
- Initiate Mirroring: The device will automatically establish a connection. Your source device's screen should appear on the display within a few seconds. No additional software or app installation is required.

4. Operating Modes
The device supports various modes to suit your needs:
- Mirroring Mode: Your source device's screen is duplicated exactly on the larger display. This is ideal for presentations, sharing photos, or browsing content while still interacting with your device. You can chat and watch without interference.
- Same Screen Mode: Similar to mirroring, this mode is great for entertainment or study, providing a direct duplicate of your device's screen.
- Screen-off Mode: This mode allows you to turn off your source device's screen while the content continues to display on the TV/monitor. This is particularly useful for focusing on watching videos or movies without distractions from your phone's screen, and it is often required for optimal 4K image quality.
