You can use anything (including a Pi) to view an hdmi stream from your PC by using this : https://www.amazon.com/gp/product/B01GZU7ZBA/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
However, if your HDMI has HDCP it will not display anything unless you have a splitter that will defeat the protection. That can elevate the price from $40 to $60 but since you were willing to cluster a Pi, there you go :D
