Does what it is supposed to do.

This cable does exactly what I needed it to do. I had recently received a newer laptop from my company (in a Tech Refresh), and the higher resolution of its (smaller) screen (as compared to the older model) had become just too small for my aging eyes. I had a separate monitor here at home, but lacked the necessary cable to make use of this larger display. Found what I wanted at Monoprice, and having used them for other things in the past, knew I need not look any further. The item simply works perfectly. Can't ask for any more than that.

I bought this item to connect my macbook to my kvm switch which only has display port inputs. So far, it is working as advertised and I am quite happy with it.
NOTE: You must plug the hdmi and usb connectors into your laptop in order for it to have power to drive the display port output.
