Can I use a spare HDMI port as an input

My computer has 2 hdmi and one dvi port on the back of the motherboard. I don't yet have a graphics card but will get it soon and likely have even more hdmi ports free. (A reference 480, I know all about how I should get a non reference card but I have a node 202 so I think a blower will suit my needs better due to lack of airflow). Is there a way to use the extra hdmi as an input into the computer? Not that I know what to use it for I'm just curious. Since my computer is sitting in between my computer desk and my television there are a lot of HDMI cables hanging around back there and just got thinking there may be some possibilities?
