Low Profile HDMI cable comes in the box, but only necessary if using a GPU 320mm or longer like the MSI Supreme X, Gaming X Trio.
HDMI is included by default because it’s more versatile. Compared to DisplayPort, HDMI is more common for monitors and television sets, and some motherboards come standard with a HDMI port but no DisplayPort port (ex: MSI B550I Gaming), so HDMI was included.
To that end, both angled HDMI and angled DisplayPort should not interfere with other connectors for multiple display configurations.
We also have a low profile angled DisplayPort 1.4 in the works for those in need.
