This port can be in DVI-D or HDMI (HDMI available upon request).

This port is a DP/HDMI combo port but can only transmit HDMI signals (unless wired as a DP port).
Please plug in a DP or 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. For detailed instructions, see https://youtu.be/SUj07rfN5l8.
