This cable works great for my use: connect my laptop to a monitor 4K Ultra HD. But beware it is very short, so you have that your PC is really close to the screen. March for 4K to 30Hz if you have the graphics card and the screen is needed, although the resolution is not too suitable for office use (saccade mouse is not the cable is of the 30Hz). I have not tested 4K 60Hz (HDMI 2.0), so I can not say if it goes that far.
