Using HDMI In with Monitor for Dual Screen

[bigmacjustin]

I have an Alienware PC with HDMI IN as well as an output. I can use it to connect my Nintendo Switch as another connection. Can I hook up another monitor to HDMI IN and have a dual screen?

Only the output can be used to connect a display to your laptop. The HDMI input can only be used to send video into the laptop.
