Connect your MacBook Pro to an external monitor or TV using a display adapter (like a Mini DisplayPort to HDMI cable). 

  • If the external screen looks perfectly normal: Your graphics card (GPU) is working fine. The problem is definitively a failing internal LCD panel, a loose/damaged display flex cable, or a malfunctioning TCON (timing controller) board. 
  • If the external screen is also discolored: The issue is a failing graphics card (GPU) on your motherboard. (Note: The 2011 15-inch and 17-inch MacBook Pros are famous for widespread, eventual GPU failures).
