Hey y'all, just wondering why I can't duplicate/extend my desktop image using a monitor through an HDMI cable. The function as monitor of my HP 23 works great, I can connect my PS4 thru HDMI and the HDMI input port of my AIO works without any issue, but as I said, I cannot get work the HDMI port to works as output to show the image signal in a monitor. Any thoughts?

The only hdmi port (5) in the HP 23 works as an input but not as an output

hi

It seems to be simple
it is only an HDMI input it is clearly indicated

HP Beats 23-n201ns All-in-One Desktop PC Product Specifications

5 HDMI In port  (not out)

that said I do not understand the usefulness of the button finally

HDMI In button (To have the computer recognize an HDMI connection, press the HDMI In button when an HDMI cable has been connected in the rear HDMI port.)

(no change if you try this button ? )

Thanks for you reply.

I know some pc models doesn't support hdmi-in feature, but for now I know some pcs like this doesn't have HDMI outputs.

Thanks again.
