Lenovo Yoga 720 Multiple display Windows 10

Hi all

I was hoping someone can help me.

Since purchasing my new laptop i have had problems with getting my two extra screens to work.

I have 3 dynadocks for my three different work offices.

One works fine, one i can only get one screen to work and the other no screens work?
All three the external mouse and keyboard works.

I have tried updating the driver and also running the cleaner.
But nothing works.

I hope someone can help me.
