Correct. DisplayPort does not have enough power for the DisplayPort to Dual-Link DVI chip so a USB connection was required for extra power.Thank you Joevt, I have seen there are two option CAC-1510 and CAC-1510 A. Which is the good one?
I also don't understand, it means that I only connect the DVI to the adapter and then the USB C to the MBP?
So I don't need to plug in the USB A as I used to do with Mini DisplayPort to Dual-Link DVI Adapter I used with MBP 2011.
