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?
iMac 27″, macOS 11.2
I broke down and got a USB type C to USB-A/USB-C/HDMI adapter and connected HDMI to HDMI. It worked.
I selected this monitor due to USB-C and it does not work. Disappointing.
Thanks for your advice.
I would test a USB-C to Display Port cable and/or a USB-C to HDMI adapter and HDMI cable.
You're welcome.
Sorry I'm fresh out of ideas, other than testing a "USB-C to Display Port cable" and/or a "USB-C to HDMI adapter" Perhaps the advise from the last person at Dell is the best way to go.
I would also touch bases with Dell Support and their Display Forum. https://www.dell.com/support/kbdoc/en-us/000131273/using-a-dell-ultrasharp-usb-c-monitor-with-a-mac
Thanks. I have been dealing with both Apple Care and with Dell Support. The last person at Dell support felt that the P2721Q might not be compatible with the iMac and I would have to return it.
Yet there is one thread in the Dell community which indicated that changing from USB type C to Thunderbolt 3 would resolve the issue. Unfortunately it did not.
Thanks. I do not have either and I will see if I can find one.
I am not inclined to buy another cable unless I know it will work. I have already spent over $100 to try a Thunderbolt which for all intensive purposes is useless.
