Adding an Asus Monitor to extend my desktop

[huy0634]

I am looking to add an Asus monitor to my all in one computer.  I want to extend my desktop to be able to have more screen space for different applications.  I am looking to use my hdmi out on my desktop to add to my hdmi on the Asus monitor.  When i plug the two together, my HP all in one screen then goes blank.  If i unplug the connection, i get the screen again on the All in one HP.  Can you help me extend my HP All in one desktop touch to a second monitor in my newly acquired ASus.  Please help.  thanks

@huy0634 , welcome to the forum.

What is the Product Number of the computer? I need this information to review the specifications of it. Please don't furnish the Serial # or other personal information. You can find the Product Number at the bottom of the page when you open HP Support Assistant.

Before you reply to my question, I suggest that you press "Windows key + P key" to get the Project menu.  Then, you should choose "Extend".  This may solve your problem.
