We had a 2009 iMac 27 that couldn't be upgraded to Catalina and a son with a 2019 13" MacBookPro that specializes in PC gaming and needed more screen real estate while running xCode . This cable helped us with that. Simply put your iMac in aim mode by pressing F2 and bam. Welcome to a dual monitor system that's way better than the previously recommended USB-C to Displayport adapter and DisplayPort male to male cable routing. the quality seems to be top notch.
