This series came in two configs with and without a discreet GPU, AMD GPU (DG) vs intergraded Intel graphics engine only (IG)

IG Models: MacBookPro11,2

DG Models: MacBookPro11,3

So lets not get lost on the different graphics this series offers as that doesn't involve the backlight.

@peach production - Plug in an external monitor with either the HDMI or Thunderbolt ports. Is that display working without a problem?
