Hi,
I've got a base 2011 iMac here. On the left side of the display spanning almost the full height of the display, is a dark line/stroke. From what I've observed it seems to be very visible on dark colours (but not on pure black) and less visible with clear colours but invisible on pure white. (I have seen it on the start-up screen for my iMac. I don't believe it's pure white though.)
What am I dealing with here?
Here's a picture:
