Hello,
i am using a 2012 27 inch iMac, the first slimline model. Now i have purchased a second hand 2011 27 inch display to use as second monitor. No matter what i do i can't get the iMac ot find it. I have done the shut down, unplug, wait 5 minutes start up again things and also the nvram reset without any success. When i connect it to a 2012 macbook pro it instantly powers up. Any suggestions what else to try? Mac os is Mojave
