1.(Mini DP+HDMI) and (Mini DP+VGA) can work simultaneously,but (HDMI + VGA) cannot work at the same time.

2.When connecting Mini DP and HDMI on macOS based system,the computer can read only one EDID (Extended Display Interface Data).So it requests the same highest resolution for using two monitors.Please adjust manually if the resolutions are different.On Windows OS the computer can read two different EDID´s at the same time.

3.When connecting Mini DP and VGA on macOS,the same.Please connect the Mini DP before VGA;otherwise,there might be no sound from the device.And adjust the resolution for both monitors manually.This will not happen on Windows OS.
