Problem connecting second monitor to HP Envy 23 All-in-One Desktop, not recognizing second monitor.

[Trishkc135]

I am connecting a 32" LG Monitor to my HP Envy 23 All-in-One Desktop via HDMI cable in Windows 10.  System does not recognize second computer at all.   One video said get a Display Port to HDMI converter, but my HP Envy does not have a display port on it, only HDMI and USB.  One person said my HDMI port was bad, so I got a USB to HDMI converter, but that did not help.  Another person said it's impossible to add a second monitor, yet I see videos on You-Tube where it has been done easily.  I know the LG monitor is good as, when I plug it into my HP laptop, the monitor comes on and functions well.  Any ideas to help me, please?

Using a USB to HDMI converter should work just fine.

Please explain with make and model number of the one you have and how and what happened when trying to use the adapter.

Do not say it did not work with no other explanation.

Sorry for the lack of information and I appreciate your reply!  I am trying to add a second monitor (32" LG 32UK50T  UHD) to my HP Envy 23 All-in-One Desktop computer.   My all in one does not recognize the LG monitor at all.  After I plug in the HDMI cable to my all in one and go to device manager, it does not list a second monitor.  I have been on the phone with 2 different computer gurus.  One said my HDMI port on my all in one was bad, so I ordered a USB to HDMI converter, but it made no difference, still didn't recognize the LG monitor.  All I get from the LG monitor is a message saying "no signal, entering the power saving mode shortly."  Someone online suggested getting an Display Port to HDMI converter and using the display cable that came with my LG instead of the HDMI cable, but I do not have a display port plug on my all in one.  However, when I plug in my HDMI cable from the LG to my HP laptop, the LG monitor comes on immediately.  I thought perhaps it was impossible to add a second monitor to the HP Envy 23 all in one computer, but I find videos on YouTube showing how to do it, so I'm truly perplexed what to try next.

Like I said earlier - make and model of the USB to HDMI is needed.  Also most of those adapters need to have software installed.  Did you do that?

BTW: some of those AIO's have a HDMI input instead of an output.  There are many different choice in the Envy 23 AIO.  Need the model number of the AIO to verify what is available and where.

Thanks a lot!  That was the problem.  Once I "installed" the converter, I got a picture on my second monitor.  Appreciate your help.  Neither of the two technical support guys informed me of that little necessity.  LOL
