Hi, I've been trying to find an answer to this but not been able to..it might be due to interpretation though. I have a 2013 macbook air to which I connect an external monitor via a Thunderbolt to HDMI Converter. It's just a basic 22" monitor. I would like to add a third monitor, but obviously I will need a thunderbolt hub. However, when reading through the specs etc on adding a third monitor, they all say that the second one needs to be a Thunderbolt one. Now, I'm not sure if that is because most hubs only have one HDMI output (for Monitor 1) and that just leaves the Thunderbolt port available for Monitor 2. Can't I just connect Monitor 1 to the HDMI port on the hub, and then connect Monitor 2 to the Thunderbolt port via a Thunderbolt to HDMI converter?
