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.
