Use Optiplex 9010 all-in-one as monitor

Hello!

I have a task, that requires me connect Desktop and thin client to one monitor and get possibility to switch between them. 

It is works fine with LG monitor - i just connect both computers to it and can select needed signal source in monitor's menu.

And now i need to do the same with Optiplex 9010 all-in-one. It has HDMI socket without tags (in or out).

Can this all-in-one computer works like a monitor for thin client?

Best regards,

Dmitry.
