Notes:
The HDMI is a DP++/HDMI combo port but can only transmit HDMI signals (unless wired as a DP++ port).
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. Please see a video
at https://youtu.be/SUj07rfN5l8 for detailed instructions.
