I am using a bidirectional USB-C to Displayport cable (CableCreation PN: CD0738) to connect my 2019 Macbook Pro to a BENQ PD2700U monitor. The description stated that this would allow not only video and audio through the display up to 8K, but also would allow charging at the same time due to the bidirectional function of the cable. So far the image and audio are great and as described, but the charging is not working.
Does anyone have experience with this? Is there a way I can enable my Macbook Pro to allow the incoming charging through this? I needed a good cable anyway, so if it only does the single function that is fine, but was hoping to limit my usage of the ports and charge and display through a single connection.
Any help is appreciated!
