2017 iMac running catalina want to use HP Windows laptop as second monitor
As the title says, I'm using an old iMac that runs Catalina 10.15 and I want to use my laptop as a second monitor but I'm having some trouble figuring out how to do that. I have them connected via HDMI cord (the Mac doesn't have a port so I'm using an adapter) but I'm not seeing an option in the Mac's settings to configure the display and my laptop says that it doesn't detect any other displays under the multiple displays option. Any clue what I'm doing wrong here? Thanks.
