Q: iMac 2011 I7 LCD or Graphic Card Issue?

I have a 2011 iMac I7 with 1GB AMD graphics that has started having issues. Upon turning the iMac on, everything loads and runs like normal except the lcd screen.....the lcd only shows the top 1/2 inch or so of the screen....then after it warms up for about 15-20 minutes, the lcd comes up showing the whole screen, except it is not crisp anymore. Also it shows lines across whole screen (kinda like the way the old CRT monitors did). I have hooked up an external monitor, and it shows a perfect picture with no abnormalities. My question is...is it the lcd going bad and not the graphics card since the external monitor works, or could it be backlight board? Any help is appreciated.

 

iMac, OS X El Capitan (10.11.1)
