ENVY 23 HDMI "in"Port not working

[Franklinmich]

I have never tried to use my HDMI "in" port so far.

I wish to use my ENVY monitor as a second (larger) screen for my laptop. 

I conneted an HDMI cable from my laptop (DELL Latitude) to the HDMI port on the left (bottom) side of the ENVY 23 monitor,

Played with the "HDMI in" button at the bottom (left) of ENV>Y 23 monitor,

Nothing happens, no menu shows up on my HP screen, NOTHING!

On my DELL:

- I can go into advanced display setting and it will show  two screens are connected (Screen 2: HP All-in-One), but I can't get it to toggle,

- Likewise, sound settings allows me to select HP All-in-One ouput, but no sound will be played on the HP.

I ran all possible hardware diagnostics using the HP tool, all came back good.

Onbviously my Dell laptop recognizes my HP Envy All in One, but that's as far as they will go in the way of collaborating.

Can you help?

@Franklinmich   Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.

That said, here's what you need to know about using the HDMI-in port:

CAUTION: 

When the system is in Display mode, the computer is still running in the background. The keyboard and mouse are active and still control the computer. To avoid making unwanted changes to open files on your computer, it is recommended that you save and close all files before connecting to the HDMI ports.

Use your HP ENVY Recline TouchSmart 23 or 27 All-in-One to play games, watch movies, and more. Use an HDMI cable to connect with devices that display HDMI, such as game consoles, DVD players, or Android devices, and then switch the computer from PC mode to HDMI mode (it does not support laptop connection)

Hi Riddle_Decipher,

Thank you for your response.

I was under the impression that I could use my monitor as a second (larger) monitor to my laptop.

See below a video introducing this feature:

You stat e(and so does the usual manual)that one should be able to connect game consoles and DVD players,  you seem to indicate this HDMI does not support laptop connection.

Is this really the case? And why so?

Thank you.

@Franklinmich Yes, I'm afraid you are right, the device cannot be used as an external monitor via a laptop as it isn't mentioned in any of the HP articles, however, you can attempt the below steps and let me know if it helps:

Some All-In-Ones will display the signal immediately, while others may require you to press the "Display Source" button,

sometimes labeled "HDMI" or "Input Switch."

• If your All-In-One does not have an HDMI-In port, it may have another type of input, such as DisplayPort or USB-C.
• The source button is sometimes located on the bottom or back of the computer.

Keep us posted,
