This device does not support HDMI displays without the addition of additional adapters sold separately. DisplayPort and HDMI are separate standards which use different cables and connectors.

Note: if using this with a 4K HDMI display, an HDMI 1.4-compliant "active" adapter such as the "Plugable DP-HDMI" must be used.
