dual monitor question

HP Recommended
HP Pavilion All-in-One 24-xa0xxx
Microsoft Windows 10 (64-bit)

I am using a HP Pavilion All-in-One 24-xa0xxx and want to hook up a second monitor.  I have another HP Pavilion All-in-One 24-xa0xxx and was wondering if I can use that as a second monitor?  Can 2 (two) All-in-One pc's be used at the same time for extending the display?

Most likely, no.

Some of the higher-end All-in-Ones come with TWO HDMI jacks on the back, labeled Input and Output.  With those, you can plug an HDMI cable into the Input jack and display content from another PC.  But if yours has only one HDMI jack, it is output only.
