How to use a MacBook Air as a Monitor using HDMI for my PC

Re: “You can't. There is no HDMI input port.”

To add to which: Don’t bother trying to use a USB-C to HDMI adapter in reverse. They generally aren’t designed ti work in that way … and even if you found one that did, the MacBook Air does not take USB-C or Thunderbolt video input.

You can't. There is no HDMI input port. Get an external monitor.
