I hope this video is useful to you! I previously had some questions concerning if you can use other monitors as an extra screen for an iMac as well as how to set it up. Below I have linked the thunderbolt (I accidentally called it lightning lol) cable adapter and the HDMI cord that you can get off of Amazon. :)
My main monitor/computer is a 2017 iMac
My second monitor is a Dell P2219H
