i don't know if my comp pavilion eleite e9300z has an HDMI input port. I can't get to the back of my comp without unplugging everything as the cords are all tight. I am trying to figure out if I can use an Amazon firestick on my comp. I would like to use it and also back up the one we have. If it doesn't what to I need to buy to be able to do this? Thanks so much for any help you can offer
