Lenovo G400: HD4000 
  When boot G400 under UEFI (UEFI+GPT) to install FreeBSD 10/11/12, the screen will blur.
  And if you do not use UEFI (BIOS+MBR), you can install FreeBSD normal.
  And I had closed my AMD devices(HD 8570M). So I think maybe something trouble in UEFI firmware.
  I invite many G400 users to test it and in the same as me.

I think it caused by DVMT-Prealloc. But I can't change it on Lenovo G400 notebook that has no setting about DVMT.
