What is your HP 23 AIO  ? HP has

• Many AIO machines do not have HDMI port at all,
• Many AIO machines only have HDMI in port,
• Many AOI machines only have HDMI out port,
• Many AIO machines have both.

Does your machine have HDMI in port ?

Regards.

yes it has HDMI port... I have both cables connected but nothing happens, already try my AOI in my smart tv and works perfect, but in this case to use it as a monitor for my MacBook it doesn't work...

I saw some post saying that I have to use a USB - HDMI IN adapter

You need HDMI in port. You can connect to TV that means it has HDMI out port. I did ask for its model/product but you did not supply therefore I can't comment on this.

I've got no idea what is USB - HDMI IN adapter  .
