Question laptop as a second monitor using Miracast

[Tomat5R]

I am trying to use my laptop as a second monitor. I have done this in the past when both the PC and Laptop were running Windows 10. The laptop has now upgraded to Windows 11 and I can't get the projection to work. Is it a requirement that both machines have to be running the same OS?

Welcome to the forums, newcomer!

In fairness, it can be done as shown in this guide. See if this guide helps you out;

Hope that helps!

I may just be confused but the article seems to show how to project from my Laptop (Windows 11) to my PC (Windows 10). I need to go the other way.

I've followed the instructions here

My problem is that when I get to the last step "Connect to a wireless display", the Laptop never shows uo to be selected. Both machines are on the same wireless network. I checked that through the router.
