Connecting laptop to the HP all-in-one

[LaraJL]

Would appreciate advice on how to connect Dell laptop Latitude 5450 to the HP all in one desktop (SKU N8X90EA#ABU  System model - 27-p000na). I would like to use the desktop as a monitor to work from home. The laptop has an HDMI port. The all in one has 2 HDMI ports, one in marked IN and the other one - OUT. I used the HDMI to HDMI male cable and nothing happened.  I wonder if someone has an idea of what what I am doing wrong? thank you!

Did you make any changes to your PC?

Have you tried checking with a different HDMI cable?

Let's us now continue with the troubleshooting.

Thanks for sharing the product details and I have checked the specifications of the PC and it supports HDMI input.

Refer the instructions below to know more information about using and connecting an HDMI input connection.

Insert one end of the HDMI cable into the HDMI-out port of the media device. (game console, disc player, another computer, etc.)

Insert the other end of the HDMI cable into the HDMI-in port on the computer, located on the lower-left side of the monitor.

Press the HDMI IN button, which is located on the underside of the lower-left corner of the monitor.

The computer switches to HDMI mode.

To switch back to PC mode, press and hold the HDMI IN button.

Did you ever figure this out?  I am trying to connect a laptop to my HP Envy all-in-one....came across something on google that stated all-in-ones  cannot be used as monitors...only video out, not video in.  I just changed jobs and need to connect the employer provided laptop to my computer....if I cannot, I now have a $1600 paper weight.....
