4. Setup and Connection
Follow these steps to connect your power adapter to your HP monitor:
- Identify the Correct Connector Tip: The power adapter comes with a connector cable that includes two types of tips: a standard black 5.5*2.5mm tip and a blue 4.5*3.0mm adapter tip. Carefully examine your HP monitor's power port to determine which tip is required.
