Notes:
1. Please gently press the power button to avoid possible damages.
2. The HDMI is a DP/HDMI combo port but can only transmit HDMI signals (unless wired as a DP
port by request). Please plug in an HDMI cable with the right orientation and alignment to avoid
damage to the connector. You should feel resistance (due to a pin on the right) if the cable is not
inserted correctly.
