Can I use Pavillion 23 (all in one) as a monitor?

Hi all!

i am looking to use my pavillion23 all in one computer as a monitor for a different device. Is this possible? If so how do I do this?

thanks!

Many of the all-in-ones only have a video-out port so you cannot use it as a monitor.

If yours has a video-in port it may also  have a button on the underside of the screen to change the display input which will allow you to see what you've plugged in.

As @GamingOptional has already mentioned, your HDMI port is most likely OUTPUT only. 

When All-in-0nes support video INPUT, they have two HDMI ports and they are clearly labeled and output.  If yours has only one, it is OUTPUT. And. any other video ports are output, also.
