Connecting a Dell P2721Q monitor to a 2019 27” iMac with 5K retina display. I have tried connecting the P2721Q monitor to the iMac using a USB type C to USB type C cable and a Thunderbolt 3 cable. No success in either case. The iMac does not recognize the monitor ( I have tried forcing detection by using Detect Displays with no luck). Does anyone have a P2721Q monitor working on a 27” iMac with 5K retina display?

Issues using my 2013 27 inch iMac as an external Monitor with my 2020 27inch iMac. Hi Everyone, I just purchased the 2020 iMac and was hoping to use my 2013 iMac as an external monitor. Unfortunately after connecting the thunderbolt 3 to thunderbolt 2 adapter and pressing Command F2, nothing happens. I've tried while both Machines were running Catalina. I tried downgrading my OS on my 2013 iMac to Mojave, High sierra, and even mavericks. Does anyone has any advise? Thanks, Jamie
