Mobile to HDMI cable

[Theguythatneedshelp]

Was just going through some stuff I had and found a cable from my Asus monitor that connects to an HDMI port and a micro-usb port. Just wanted to know, what is that for because just plugging it in doesn't seem to work on any of my phones.

Phone would have to have that feature and appropriate APP for it to work that way.
