Just what I needed to connect my new ThinkPad X1 Carbon to my existing Dell external monitor. Very satisfied. Always been happy with Monoprice products. Gladly recommend to others.

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.
