New as delivered HDMI port didn’t work but display port connection did so set it up that way. Used known good HDMI cables and display that worked side by side with old HP system but wouldn’t work either the new dock. Since I had display port cable I just used that as it worked and I didn’t want to wait on a new dock or go through the hassle of warranty exchange.
Would of rated it 5 stars if HDMI port would have worked.
