Undo remove display from desktop

I am using a virtual machine to connect to my client's network via Citrix. I have accidentally removed the only display using the "Remove display from desktop" option from the settings and now I am unable to access my VM. I have tried restarting the virtual machine but that didn't work. I am looking out for an option to undo this. Any help would be highly appreciated.

Thanks in advance.

 

Restore display from "remove this display"

I had right clicked on the desktop and selected Display settings. My TV was list as a monitor there. I selected the monitor and clicked
Remove this display.

The above steps has not resolved my issue.

 

Undo remove display from desktop

What would be the solution if this same problem happened on a network computer? Is there anything the technician can do besides completely re-imaging the computer? This very same thing happened to me this week. While remoted into my work computer, I accidentally removed my second display at home from the work laptop. So at work, both monitors still work, but I desperately need my home computer to still utilize the second monitor when I'm logged in. I'm kind of surprised something so seemingly permanent as "remove display from desktop" was such a simple, one-step toggle in the first place. (And I'm even more frustrated at myself for clicking it.)

Is there no other way to get it back without completely rebuilding the work computer? Thank you.
