Sorry but that is no longer possible or supported by the newer Mac's.

Plus it is considered thread jacking, to ask a totally different question than the one aldezines has asked.

What brand and model is the external monitor that you are trying to use with the iMac?

What brand of USB-C to HDMI adapter or adapter cable are you trying to use?


While some aftermarket USB-C to HDMI adapters may work, I suggest paying the piper for the branded USB-C to Multiport adapter or the Belkin USB-C to HDMI adapter.

Oh perfect - not very smart at all


also, I don’t care if it’s “thread jacking” or whatever you have called it - I had a question and google brought this up so I asked it. Sorry if there are online cyber rules to follow buddy. Sure everyone will survive it though.
