Function Description

The LG Projector is designed to display content from smart devices (smartphones, tablets, laptops) and to output audio wirelessly to Bluetooth speakers or headsets. It supports both wired and wireless connections for video input and wireless connections for audio output. The projector can enlarge the screen of connected smart devices, making it suitable for presentations, entertainment, or other viewing needs.

Usage Features

Connecting Smart Devices (Wired Connection): To connect a smart device via a wired connection, use an appropriate cable to link the smart device to the projector's HDMI port. The projector's external input should be set to HDMI. The smart device's screen will then be displayed. The type of cable required depends on the smart device:

• Slimport supported devices: Connect via an HDMI cable and a Slimport adapter. The projector's HDMI port receives the video, and the projector's USB port can be used for charging the smart device.
• MHL (5-pin) supported devices: Connect via an MHL cable to the projector's HDMI port (MHL supported port). This also allows charging the smart device through its charging port.
• MHL (11-pin) supported devices: Connect via an MHL cable and a 5-pin to 11-pin converter to the projector's HDMI port (MHL supported port). This setup also supports charging the smart device.
• Apple Lightning Digital AV adapter supported devices: Connect via an HDMI cable and a Lightning Digital AV adapter to the projector's HDMI port. This allows the smart device to be charged through its charging port.
• Apple 30-pin Digital AV adapter supported devices: Connect via an HDMI cable and an Apple 30-pin Digital AV adapter to the projector's HDMI port. This also supports charging the smart device. It is important to note that cables are purchased separately, and specific instructions for wired connections may vary by smart device manufacturer.

Connecting Smart Devices (Wireless Connection): For wireless connection, press the "INPUT" button on the projector's remote control and select "SCREEN SHARE." Then, launch the relevant SCREEN SHARE function on your smart device (e.g., Miracast, Screen Mirroring, Wireless Mirroring for Android; Intel WiDi, Miracast for Windows laptops). Search for the projector on your smart device and connect. Once connected, the smart device's screen will be displayed through the projector. For detailed instructions on the smart device's SCREEN SHARE function, refer to its owner's manual.

Connecting Bluetooth Audio Devices (Speaker/Headset): The projector can connect wirelessly to Bluetooth audio devices to output sound.

1. Press the "SETTINGS" button on the remote control and navigate to "AUDIO" → "Sound Out" → "Bluetooth."
2. Set your desired Bluetooth audio device to Pairing mode (refer to its manual for instructions).
3. Select "Search Device" on the projector to find available devices. The search takes about 15 seconds. You can stop the search by selecting "Stop searching."
4. Once the device appears in the list, select it to connect. The connected device will be automatically added to the "List of registered devices."

Managing Registered Bluetooth Devices: Bluetooth audio devices that have been connected previously are automatically added to the "List of registered devices," allowing for quicker reconnection without a new search.

1. Press the "SETTINGS" button and go to "AUDIO" → "Sound Out" → "Bluetooth."
2. Select "AUDIO" → "Sound Out" → "List of registered devices." Ensure the desired Bluetooth audio device is turned on.
3. Select the desired Bluetooth audio device from the list to connect.

Maintenance Features

Wireless Connection Stability: If the wireless connection to a smart device is weak or unstable, adjustments can be made:

• Change settings in "Group" to improve the connection.
• Press the "SETTINGS" button, then navigate to "WIRELESS" → "SCREEN SHARE" → "Channel" → "Manual" to change channel settings.
• For supported models, using the 5.0 GHz band is recommended for better stability.

Bluetooth Audio Connection Management:

• If Bluetooth is enabled on the projector when it is turned on, the most recently connected Bluetooth device will attempt to connect automatically. Ensure the Bluetooth audio device is turned on first, as some devices automatically turn off.
• If there is a delay between the screen and the Bluetooth audio, adjust the synchronization using the "AV Sync. Adjust" option.
• For optimal performance, it is recommended to keep the projector and the connected Bluetooth device within 5 meters.
