Retina display resolution and 1080p videos There is something I don't understand.
I have a macbook pro 15' retina display.

The information says it has a 2880 x 1800 display but when I open a 1080p video it covers the whole screen. How come?
This was probably done so that videos, especially those that are lower resolution than 1080p, don't look absurdly small. If you want to play your video at the native resolution on your screen, (and you've selected "best for retina" as your display resolution), you could always tell VLC to play it back at half the size.
