Black screen on external monitor?

When I connect this monitor to my laptop (lenovo y510p) it is correctly detected by my system, but whenever I turn the monitor on, it only displays a black screen.

Anyone know why this is happening? I've updated my drivers, so that probably isn't the issue.

I'm also using a dvi to hdmi cable
