3. Setup Instructions

Follow these steps to set up your CABLEDECONN 4-in-1 HDMI Adapter:

1. Connect Input: Plug the HDMI male connector of the adapter into the HDMI output port of your source device (e.g., laptop, set-top box, Apple TV).
2. Connect Output Display: Connect your desired display (HDTV, monitor, or projector) to one of the adapter's output ports (HDMI, DVI, or VGA). Important: Only one display output (HDMI, DVI, or VGA) can be used at a time. Connecting multiple displays simultaneously is not supported for extended desktop functionality.
3. Connect Audio (if needed):
   • For HDMI Output: If your HDMI display has audio output, both video and audio will transmit simultaneously. If your HDMI display lacks audio output, connect a 3.5mm audio cable from your input device's audio jack to external speakers.
   • For VGA Output: VGA does not transmit audio. Connect the included 3.5mm audio cable from the adapter's audio jack to your external speakers for sound.
   • For DVI Output: DVI does not transmit audio. Connect a 3.5mm audio cable from your input device's audio port to your external audio devices for sound.
4. External Power (Optional but Recommended): If connecting high-power devices or if the adapter's performance is unstable, connect the Micro USB power cable from the adapter's 'Power' port to a 5V USB power source.
5. Configure Audio Settings: In your input device's audio settings, select the appropriate audio output device (e.g., HDMI display for HDMI output, or external speakers for VGA/DVI output).
