HowTo: Connect 2017 iMac to an Apple 27" LED Cinema Display

#25

Hi, below is how i connected mine to a 20" Cinema Display...

Here's how i did it...
So, going from the iMac to the Cinema display, this is the route I took and the leads/adapters I used (please note I am not technically minded, more a creative... !!):
CHOETECH V-CH0018 USB Type C to HDMI Cable
At the HDMI end of this cable I used a HDMI Female/Female connecter
From the female connector I used a HDMI to DVI-D Cable
Then at the end of this I used a DVI-D Female/Female coupler
Then the female end of the coupler into the Cinema Display adapter which comes out of the back of the cinema display.

You do know that you have 90 days of free technical phone support right? Rather than counting on other users or random internet articles maybe Apple Support would be kind enough to give you an official answer.

Hi There!

I followed your advice and purchased the exact three items and plugged them in just now and my brand new iMAC 27 inch still acts like the Apple Cinema Display Screen is not attached. I have rebooted. Unplugged and replugged and restarted and played with all the System Prefs for Displays but even with those three items from Monoprice I get nothing. If I unplug the Cinema Display and plug it into the Mini Display Port on my Macbook Pro it fires right up and I get a mirrored image on the Cinema Display. No such luck when plugged into the new iMac.

Any ideas???

I am happy to report I was able to successfully use the parts listed to connect a 27" Apple LED Cinema Display to a 2017 iMac. Thank you so much for this information. I really appreciate the time you took to try this out and report on it!

Bob- during my setup of these parts, I made the mistake of not connecting the two Mini DisplayPort connections into the Mini DisplayPort Female-to-Female tight enough. Nothing worked so I started playing around with the various connections. I noticed those two connections were loose. I had to use some slight force to actually fit them in. Once I did that, it worked. Initially, I didn't want to force things in, but that did the trick for me.

For UK users not all those parts are readily available and there's a simpler solution.
I have connected my 24" LED Cinema Display to an iMac (Retina 5K, 27-inch, 2017) as a second display using:

UGREEN USB C to Mini DisplayPort Adapter USB 3.1 Type C to Mini DP Converter Cable with Power Delivery Support 4K for Apple MacBook Pro 2016, ChromeBook Pixel, Samsung Galaxy S8, S8+, Aluminium Silver

It works perfectly and cost £15.99 including delivery.

I have connected my 27" LED cinema display to iMac 5k 27inch with the same adapter (UGREEN USB C to Mini DisplayPort Adapter USB 3.1 Type C to Mini DP Converter Cable) amazon Australia - worked straight away thank you so much for the post !

I also purchased the exact three items and, after waiting a long time for them to arrive, plugged them in to my new iMAC 27 inch which also still acts like the Apple Cinema Display Screen is not attached. 😠

troika, your Cinema Display is a generation older, and doesn't use a MiniDisplayPort as mentioned in the original post.

What you have there is I think a DVI connector (along with FireWire and USB cables). Hopefully this will help you to find the right solution, if you didn't already.

I have bought all the cables listed above and not one of them connect to the cables someone out of the Apple Cinema Display monitor? Can someone help? Thanks (Pict Attached)

See if this article helps. He points to a couple usb-c to display port options http://blog.fosketts.net/2016/10/30/2016-macbook-pro-usb-cthunderbolt-survival-g uide/
