    I just purchased a 2015 macbook pro and i swear that every time i use it i get a headache and/or dizzy. I have read a few people that this has happened to, i put it at "Default" resolution, and I think that everything looks too blown up. So I use the one to the right of that. I had a macbook air previously, and didn't seem to have this issue.... Do you think I should exchange for MBA or try to get use to it? Ive lowered brightness as well.

    Any other suggestions would be helpful, I'm ok with going back to a MBA. I have a Ip6 and don't seem to have the issue with the screen.

    Thank You!

    The default resolution scales it down to match how the non-retina macbook pros looked, only sharper. Are you sure it's the screen, and not how you use it?

    I suspect it's the 13" model as the 15" 2015 model is not yet available.

    the 13" has a 2560 by 1600 pixels screen resolution. I suspect you can get dizzy by using scaled resolutions and I will explain you why.

    First, the resolutions I would recommend you are either "default" 1280 x 800 pixels ( like the non-retina macbook ) or the 2560 x 1600 resolution - but in this case everything will be very small, so I'd stick to the first.

    So... by using the 1280 x 800 resolution, you'll notice a factor of 2x both horizontally and vertically compared to the screen capabilities. This means that instead of lighting one pixel, the screen will light 4 pixels ( 2 x 2 ) and this is perfectly fine. When dealing with text or images, the screen will adapt and light the pixels in a different manner, thus providing very sharp images and text.
    That's why I was recommending 1280 x 800.

    So what's wrong with other resolutions?
    Let's take 1440 by 900. This corresponds to a factor of 2560 / 1440 = 1.78 horizontally and 1600 / 900 = 1.78 vertically.
    So when the screen receives the command to display a blue pixel, it should light 1.78 pixels x 1.78 pixels blue which is impossible as you cannot light part of pixels. It's one pixel or nothing. So what happens is that the image is re-calculated and in the end distorted, in order to display it on a non-optimal resolution.
    And I suspect this is the cause of your problems. I also cannot handle such sub-optimal resolutions.

    So... please try to use the screen in 1280 x 800 and see if your problem persists.
    I suspect it will go away.
