I currently have a macbook pro with 2 thunderbolt 3 ports and integrated graphic card and a belkin dock that I use for work, but can't get work done with just 1 monitor. I have a triple 1080p monitor setup at home that uses VGA and/or HDMI and was wondering if there is anyway I can use all 3 monitors with my laptop. Please keep in mind that although the dock has 2 thunderbolt ports one is used to connect to the macbook and the other I need to use for my yubikey. So in total I only have 1 more thunderbolt port free (the one from the macbook). Thank you guys!

In order to get this setup working, you'll want to get the following:

  • 2 x Thunderbolt 3 to HDMI cable
  • 1 x DisplayPort to HDMI adapter-cable
  • 1 x USB-A to USB-C adapter

You would connect the first monitor directly into the MacBook Pro using the Thunderbolt 3 to HDMI cable.

The second monitor connects to the dock's Thunderbolt 3 connector using the Thunderbolt 3 to HDMI cable.

The third monitor connects to the dock's DisplayPort connector using the DisplayPort to HDMI adapter-cable.

The YubiKey connects to one of the dock's USB ports using the USB-A to USB-C adapter.

  • But will this work ? Since the dock is using a Thunderbolt port, which does not allow for daisy-chaining displays unless it is Thunderbolt 2 or the newest revision of DisplayPort (and mine are HDMI) Also, thank you for answering!

  • You seem to have things mixed up. The dock is not using Thunderbolt (as in the original Thunderbolt). It use Thunderbolt 3. Thunderbolt 3 does allow for daisy-chains containing displays. And yes, it does work. I have a Thunderbolt 3 dock and use the DisplayPort as well as the Thunderbolt 3 ports for displays.

  • Nope... it’s rare to see HDMI only monitors these days. I would prefer DisplayPort always.
