I have a 2014 MacBook Air with the Intel HD 5000. I bought the csv-5200 and have it set up as follows: mini displayport to displayport cable > MST Hub > displayport to hdmi x2. I’ve got bootcamp installed and have tried to get both external monitors to be recognized with both windows 8.1 and OSX Yosemite, but it only detects one, and mirrors that one’s screen on the other. I’ve tried updating drivers, plugging and unplugging the hub and power cycling all of the components, still no luck. Anyone have any ideas?

Thanks!
