Use my HP Envy all-in-one as a monitor for my laptop

HP Recommended
HP Envy all in one desktop
Microsoft Windows 10 (64-bit)

When I work from home I want to plug in my HP laptop to my new HP Envy all in one home PC to take advantage of the larger/wider screen however I have two issues:

1. I can get them to connect via HDMI cable and switch to the laptop screen on my Envy but the cannot get the aspect ratio fixed. The picture is stretched to fit the Envy's widescreen.

 

2. The mouse is no issue, but can I somehow pair my new HP Envy all in one keyboard with my laptop (it has an internal USB connection so I can't just switch the dongle from device to device)

 

Any assistance would be awesome. Thank you!!!!

We need the model number of the two computers. I am gathering you can somehow get the AIO to act as an external monitor for the laptop?

Thanks for the speedy response!

My laptop is an HP EliteBook 840 G3

My new desktop is an HP ENVY Curved all-in-One 34-b1xx

 

Both units are x64-based

Thanks - I posted the model numbers. I can connect via HDMI to the AIO however the picture is so stretched it's not functional. I've tried every aspect ratio and display setting I can find to get a better view on the AIO but with no success. To try to get a mirrored image, shared mouse and shared keyboard, I tried the bluetooth connection function on both devices, this works but with several limitations: the mouse loses a little functionality (it won't drag open windows around), I get two large black "banners" left and right of the widescreen display, so I lose a ton of usable screen real estate and the worst piece is that I need to connect to my work via a VPN which totally stops the bluetooth connection from functioning.

 

Sorry for the essay, but each solution I've tried has presented a variety of challenges to overcome. Any assistance would be greatly appreciated.

Specs for the 840 G3 say it has a Displayport not HDMI. Are you using an adapter? It is possible the HDMI output will not support the very high resolution of the AIO.

I am using an HDMI adapter to connect to the displayport, and it works just fine when I connect to any other large or widescreen "monitor" at my office building using the same adapter/displayport set up.

 

Many, many thannks for your advice and assistance

But are the other monitors you speak of 4K resolution?
