Screen flickering when booting into kali-live

Hi, im trying to boot into kali-live on a usb but the screen starts flickering like crazy. I'm on an Acer Aspire V3-772g, i believe it might be a hardware issue because if i connect my external monitor, the external works great. The problem could be that my laptop has this Nvidia-Optimus **** that lets you use 2 graphics cards, in my case an Intel HD 4600 and a GTX 760m.
Any ideas how to fix it?

Some more info that might help:
-Kali version: 2016.2
-SecureBoot is off
-I'm in EFI mode
-I used dd to create the usb-drive, 2. time i used Win32DiskImager (same result)
