    Hi everyone

    Just received my new MacBook yesterday, very pleased :)

    I'm not particularly computer savvy and am a bit confused about resolutions. I do, however, understand screen estate and have read people saying they are changing their resolution for more screen estate.

    This is where I get confused. Surely unless you have 1152x720 you won't get the hignest DPI (226).

    So my question - what DPIs do the scaled resolutions give. I would like more room on screen, but I don't want to sacrifice the retina display too much.

    The DPI of the screen is fixed at the screen level; it doesn't change when you change resolutions. 1152x720 is just the 1/4 resolution so that there is no heavy graphics processing required to keep a sharp image. It should be the sharpest with the least amount of hardware overhead. At the other resolutions the graphics card must render the content off-screen, then scale it to fit the size of the screen, and since it's not a perfect integer scaling, in theory it's not quite as sharp, and requires a bit of extra processing. In practice, I find the other resolutions to be acceptably sharp with little additional lag occurring, so choose the resolution that suits your needs best and forget about it. :)

    OK great thanks :)

    I've just noticed the default resolution is 1280x800 so it's obviously doing this out of the box.
