My LG monitor is connected to my iMac but it cannot be detected. I have an iMac (Retina 4K, 21.5-inch, 2017) and I am trying to connect an external 4k LG monitor 24UD58. It is connected via a USB C to HDMI adaptor (the apple one). No matter what I try the iMac doesn't detect the monitor. I have tried restarting with all connected, powering up and connecting etc etc. I have tried detect displays but nothing is found. I have tried all cables and monitor with my MacBook Pro and it works with no issues so I know the issue if coming from my iMac, anyone else had this issue and know a fix?
