I have the Thunderbolt 2 Express Dock HD (Model no. F4U085) and I have a question to ask. The dock is attached to a Macbook Pro and everything works fine (audio, ethernet, USB devices etc). However, I cannot connect dual displays to it. My dual monitor setup is as follows: I want to attach one monitor via the HDMI port on the dock and the other via the thunderbolt port on the dock, using a MiniDP to HDMI adapter + HDMI to DVI cable to the external monitor. When I tried the setup, one of the monitors (the one connected to the HDMI port) has no output to it. If i connect it to the HDMI port on the macbook, it shows the output.
According to the official product guide, it says:
Yes. For dual display, at least one (1) display has to be Thunderbolt or Thunderbolt 2 technology. For displays that are not Thunderbolt technology ready, Thunderbolt port is backwards compatible with Mini DisplayPort and dock supports either HDMI or Mini DisplayPort but not both.
How can I connect dual displays to the dock ? I find this somewhat unexplained. Do I need to use an actual thunderbolt cable for one of the monitors , not an adapter? If I buy a thunderbolt cable and a thunderbolt enabled monitor, will I be able to use the HDMI port on the dock for the second monitor ? Or the only possible dual-display scenario is with thunderbolt daisy-chaining? Has anyone had any experience with this issue?
