How to hook up 2 monitors + laptop display with Pavilion dv7?

[Oldpaviliondv7]

Reposting a question asked before by another user, which was answered with a blank link. I’m having the same issue as mentioned by the prior user. I have a HP Pavilion dv7 Notebook PC, Windows 10, and AMD A6-3400M APU with Radeon(tm) HD Graphics. In the display settings I only have the option to extend between the 2 monitors or extended between the laptop and 1 of the 2 monitors. It won’t let me extend all 3. Here’s the question previously posted: 

“i'm trying to hook up 2nd extended display to my HP Pavilion dv7. The first one works fine over VGA cable. For the second one I'm trying to use DVI output from the monitor and HDMI input to the laptop (as my laptop has only one VGA input/famale connector). 

However, once i connect 2nd monitor (via DVI-2-HDMI) and open the windows utility to define extended monitors, 3rd monitor appears grayed out and can't be "Identify"-ed. If i set "Extend desktop to this display"  for this monitor, it becomes active but it DISCONNECTS the 1st exdended display. So, no matter what I do, looks like I can use only 1 of these extended displays. Is there any way I can hook them BOTH up so that I have total of 3 displays (laptop + 2 extended ones)?”

Any help would be appreciated.
