If you have an iMac made in mid-2011 or later, here is how you can use it as an external monitor.

I'm in the process of building my first PC rig (aimed towards mid range gaming), and was wondering if it were possible to use my Mid 2011, 27" iMac as a monitor for the PC?

I have an iMac DV at 400Mhz and eventhough i dont plan to upgrade any time soon i am interested to know if i could use it as a second monitor when/if i will buy a tower.

You have an old iMac that has a perfectly good display. Wouldn't it be great if you could use it as a second monitor with your new MacBook Air. You can, but you may be underwhelmed by the results.

New iMacs can use Universal Control, but or iMacs from 2009 to 2014 can be used as external monitors when running certain versions of macOS.

Multi-monitor workstations are a surefire way to improve your productivity, whether you're using one of the newest Macs or a great PC.
