Connect additional monitor to HP All in one

HP Recommended
Hp all in one

Hp can't detect monitor. I followed all previous comments and tried everything. Connected a monitor to Hp all in one with hdmi. Success!. It is mirroring the hp. I need to extend to the extra monitor but hp does not detect.

Went to display adapters to update driver but only the basic hp monitor is listed - says driver already installed. 

I see no mention of the extra monitor for me to update....tried to reconfigure with no success. Any ideas?

HP has many Hp all in one models/products


  • Some machines only have HDMI in for games consoles,
  • Some machines only have HDMI out for additional monitor,
  • Some machines have both.

Does your machine have HDMI out port ? What is it ? Please use the following way to see what it is
