Price is very reasonable. Outfit looks good aluminum case, size is a little larger than the mini adaptor. This item is a a little expensive, but works.

I use a hp ultra slim docking station for my work laptop. I have two monitors that support hdmi and the graphics card on my workstation had 1 hdmi port and 1 display port.

Screen stays completely black. My graphics card only has hdmi plugs. Seems to black out more often when pushing audio through the adapter to that monitor, but also does it with no audio being pushed to the monitor.
