the multi stream transport hub for 4 Display is working but only with 3 displays. What can i do to use 4 Displays. The graphic chip in my pc is a Intel HD 520.
Tank you 🙂
This is most probably ue to the fact that your source system, or better yet, its HD 520 graphics, does not support more than 3 screens total.
There is most probably a, Intel Core i5-6300U CPU inside your system, this is a very often used CPU, which has Integrated Graphics HD 520. Thsi does have support for DisplayPort 1.2 but is limited to support max 3 external screens.
What system do you have (Brand / Type)?
and here’s the link to the driver, in case that mini cd does not fit 🙂
