On my rMBP I don't believe its image retention. But when I transition with 3 fingers I can see that in the middle there's a dark area thats in a form of a line. You cannot tell when the images on the screen are still. But when I transition I can see there's a slight dark area.

I'm not sure what I should do with it, it's not a major issue I can't live with. It just bothers me but I really don't want to go through the return/exchange hassle.


Samsung screen btw.

EDIT: More words to describe it is, a very very vague blemish only noticeable when on a white background and in transition.

Is it similar to:

Have you tried changing the screen to all black? Do you still see 'blemishes' there?
The way he describes it its similar to my issue but this time its vertical right in the middle and you can't notice on black but instead , white because its a black faint vertical line.

I've seen the same thing on 2 Samsung panels (rMBP). See my original post:

EXACTLY YOUR POST ^ Can only see it when moving windows!

Did you end up returning yours? Everything else with my screen is fine, I just really don't want to end up exchanging and getting one with more issues..

What you are talking about is called DSE (Dirty Screen Effect) in the LCD/LED TV world. It's only visible when there is movement on the screen that your eye is actively tracking, against a white background. On televisions it is most noticeable when watching an ice hockey game.

DSE is visible to a greater or lesser extent on all LCD panels. It's a brightness uniformity issue that is extremely subtle and barely visible, if at all, when viewing static images. If you exchange your machine, be prepared to get another with a similar issue but in a different place on the screen. You may also get a perfect panel - there is just no way of knowing.

I have DSE on all of my Mac monitors and all of my Mac laptops that I've ever purchased. You have to look for it in order to see it, but it's there. I even have it to a small extent on a high-end calibrated wide-gamut 30" NEC LCD monitor that cost over $2,000. This is simply inherent in the technology and all manufacturers allow a certain amount of DSE as "within spec".

If it really bothers you, get an exchange, but your next screen may have other problems that are more visible.

Thank you so much that explains a lot. I'm trying my hardest to not let it bother me to avoid the exchange.
