2016 970m blade, in the use of akitio node external graphics card dock, the external display directly connected to the external graphics card, you can use the normal graphics card. Laptop connection card after docking, and then use the external display, connected to the notebook with HDMI can also be used, but the loss is relatively large. However, I use the card dock directly connected to the computer, directly use the laptop screen, although the computer can identify the card, but it seems unable to use high performance graphics card in the dock, when running the program is also the default directly run in 970m, this is why? How can I switch to an external video card? Or must we use Razer's own core?
