Acer to Hp laptop Via Usb-C

Hello so I have a small understanding as I do entertainment at school so I know what a HDMI is and a USB-C. I have looked around my home and there isn't a HDMI not in use and I want to connect my ACER laptop and my HP Laptop and be able to throw my acer screen to my hp and the other way around. I was trying with a USB-C but it doesn't seem to be working can I have some help please?
