My new (well, refurb) iMac 24 arrived on Tuesday March 17. So after 36 years in software development, I am again a newbie, since this is my first mac. The screen defect I am writing about is pretty minor, but just wanted input. I used piXel Check. On each color and black, no issues. But on white (that is, full white screen) I see in the lower right corner some brownishness. Is this what people have been talking about? It is kind of brownish in a small area in the lower right, and same thing in lower left, but much less. It is hardly noticeable and I am wondering if I should just live with it, or what my options are.
