And the ethernet also. If I suspend the macbook, unplug the GN30H and the second screen which uses another USB-C, when I want to plug again with the both monitor, the screen plugged on the GN30H (stay black) Any idea ?

Thx Jerome March 16, 2019 at 12:33 am #13728 LucasParticipant Whats the point of having a customer service Q&A if you don’t answer your customers. Wish I’d read this before I spend 100 AUD on this paper weight. I now have two options, throw the qacqoc in my bag and never use it or purchase another screen with thunderbolt Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
