HP Pavilion Power 580-137c has three HDMI outputs, only one works?

HP Pavilion Power 580-137c
Microsoft Windows 10 (64-bit)

Hey ya'll, subject says most of it. How and why don't these two ports work, and how do I get them to. The product is advertised as having 5 multi-monitor support but notes it "may require an active adapter", which makes no sense to me, if it's referring to the two inactive HDMI ports. Can I get the gpu to support these outputs??

 

 Unless this is fixed I'll have to make do buying a Displayport cable, but I'm not happy about it.

Its specs

 

   https://support.hp.com/au-en/document/c05686933

 

which says

 

    The Basswood motherboard does not support integrated graphics.

 

Therefore two HDMI ports on the motherboard won't work. It has 3 HDMI ports:

 

  • One from AMD Radeon RX 550 video card
  • Two from motherboard

and the following 2 ports won't work

 

Figure : Basswood back I/O panel
 
  1. USB 2.0: 2
  2. LAN (Ethernet)
  3. HDMI out: 2
  4. USB 3.0: 2
  5. Audio: Line in
  6. Audio: Line out
  7. Audio: Microphone

You can connect up to 5 monitors BUT the specs says "Full multi display support might require an active adapter." but at least you can use  DL-DVI + HDMI + DisplayPort ports on the AMD Radeon RX 550 video card.

 

Hope this explains why ONLY one HDMI port is working.

 

Regards.
