HELP needed to set up a second screen/monitor on an iMac 2021 M1

Hi guys,

I am using a 2021 iMac M1 and I need to set up a second screen/monitor.

I originally wanted to hook up an older late 2011 iMac as the second screen but I believe the new 2021 models don’t allow you to do this anymore…

Is it just a case of getting a usb-c to HDMI cable/hub so the usb-c goes into the iMac and the HDMI into a monitor?

I’ve found conflicting info online and don’t want to waste money on getting the wrong lead/set up but at the same time want to spend as little as poss to hook them both up.

I’ve found a few hubs on eBay but not sure if they would work as I know Apple products can be temperamental with non-apple branded leads and adapters.

Any help would be appreciated!

Yes a USB-C to HDMI adapter is what you need for an HDMI equipped external display.

Apple sells two USB-C to HDMI adapters and other aftermarket adapters may also work.

Thanks for the reply!

Does it have to be an adapter? Or will a usb-c to HDMI lead work?

I’ve attached some images of what I have found - one just the lead and one is an adapter/hub but considerably more affordable than those in the apple store.

So just wanted to check if they will do the same job essentially…
