Macbook webcam on second monitor

I have tried to find the answer, but I could not find in the forum

Here is my set up: I am using pluggable usb 3.0 docking station with MacBook Pro 2015(non-usb c-type connection) and Asus monitor as an external display connected HDMI input/output .
Whenever I am trying to use webcam on the second monitor webcam windows is totally black and vice versa, I cannot see other sides webcam as well. This issue mostly happens with Skype and gotomeeting.

Please correct me if I am missing something, thank you for your help

Hi Otabek,

Thanks for posting!

Just a few quick notes…first, we also received the direct inquiry you sent to but I am only replying here to help keep all communication in one place and for the benefit of anyone else following this thread.

Second, we actually don’t recommend our USB 3.0 Dual Display Docking station for use on the Mac because of OS limitations that can lead to performance issues (our most recent article on the subject is here if you are curious ->…).

To the behavior with Skype, this is a known issue with applications that require hardware graphics acceleration that DisplayLink (the maker of the chip in our dock and driver author) speak to here ->…

That said, the next release of macOS (version 10.13 known as ‘High Sierra’) when used with a future release of the DisplayLink driver will support hardware graphics acceleration on certain Mac systems, and that may resolve the Skype issue. DisplayLink speaks to these updates in their support forum here ->… and here ->…

The workaround for the interim (as you have already discovered) is to run Skype on the internal laptop display.

Please let us know if that information helps!
