theres a blue line on my iMac and i am not sure why because if it fell i would know and i tried resetting it by pram but it still wont go away and can be seen on some backgrounds and its distracting so i want to know is it a hardware issue or a bug or maybe is it the screen?
iMac Line (2012 and Later)
Take a screen shot & view that in Preview, move the Preview window around, if you see double lines it's a Video card/VRAM problem, if the lines do not move moving the pic around then it's the LCD or cable.
