Hi! I got my first iMac delivered 11 days ago, after using MacBook Pros with external displays for years. The problem is that I'm getting severe eye strain and blurry vision when using the iMac. I only have until monday to return it so time is scarse. My question is, has anyone had these kinds of issues with retina iMacs and managed to mitigate them successfully? With successfully I mean still using the machine without issues. I have always been sensitive to some displays while other work fine. All other Apple retina displays I have used have worked better than any other displays I have used in the past, so this was a bit of a surprise. I have brightness turned way down and it doesn't help much. My options now are to either solve the problem and continue using it, return it (in which case I'm kinda screwed since it's the only Mac powerful enough right now), or use it with an external display and not use the internal display at all, which seems like a huge waste. It would be great if there was a Mac with the power of the iMac without a display and a price to reflect that difference. Any ideas?
