Does this adapter work okay to connect a monitor to an iMac with OS Sierra?

MyQuestion, If I plug this into one of the new (late 2017) iMacs with Thunderbolt 3, then plug the other end into my VGA monitor, will that monitor EXTEND my desktop...be a monitor I can use with my computer; or will that monitor merely MIRROR whatever's on the main screen.

  • Yes. I have just purchased Belkin's black version of this product and it does indeed work with a 2017 iMac. It plugs into the Thunderbolt port on the iMac and works exactly as expected. The Displays panel in preferences allows you to select whether you want to mirror the iMac or use the extra monitor as a second screen.
