Third monitor on HP Pavilion All-in-One - 27-xa0009

[comocomo]

I am wanting to connect third monitor on my all in one computer (HP Pavilion All-in-One - 27-xa0009). But it seem to only detects 1 additional monitor.

When one additional monitor is connected it works fine with extended mode. However when I add the 2nd monitor to my all in one(total 3 monitor set up) the third monitor will only mirror the 2nd addtional monitor and won't let it extend or detect the third monitor. (I have HDMI splitter as well with multiple output)

Is this simply because the HP Pavillion All-in One cannot handle the extended feature? If anyone could help it would be great. 

Here is some additional info about the system.

The HDMI splitter gives 2 monitors on thew same port, you can extent them. The specs of your machine does not say much about 2 USB-C ports

  

• 1. DC Power input: 1
• 2. RJ-45 connector: 1
• 3. HDMI in: 1
• 4. HDMI out: 1
• 5. USB 3.0 port: 3
• 6. USB 3.1 Type-C port: 2
• 7. SD card reader: 1
• 8. Audio jack: 1

Therefore you have to do the way notebooks/laptops people do: please enter your requirement on the following link and it will find for you few USB-A DisplayLink Certified options on market today including some HP products (you can select HP before Search)
