Adding a second monitor works then 2nd monitor goes black

HP - 15 Touch Screen Laptop

I am working on my sister-in-law's laptop attempting to connect a 2nd monitor.  I have just replaced her RAM to 8 GIG (factory was 4 GIG)  and thought it would be easy to just hook up this second monitor.  We purchased a DVI to HDMI cable, hook the cable up to the monitor. Make sure there was power to the monitor.  Then I change the display settings to mirror the displays.  The second monitor turns on and shows the display however it in a split second turns black.  Power is still on for the 2nd display however it just displays black.    The graphic card I have in the HP-15 touch screen is the amd radeon (tm) r4 graphics.  I am wondering if I turn off the touch screen ability would it work or if anyone has any tips to get this second display to work please let me know.
