Allowed two external screens and main laptop monitor to be used, total of 3 screens at once. Perfect for work

Does not work for Apple Mac computers. It only allows for the second display to mirror the first on a Mac.

No issues at all. Plugged in my Lenovo X1 and worked straight away.

Although both HDMI ports work, they are forced into mirror mode as Mac only sees one display.

bought this a few weeks ago for work and works perfectly on my Dell laptop quality of item is great not like those flimsy one you get from other stores.
