    So I have a nMP with El Capitan connected to a NEC 4K monitor. And the default settings for resolution is 1920x1080. So does that mean that at that setting I don't get to see full 4k video and it will be scaled down? Or is that 1920x1080 just referring to the interface of OS X and I will still be able to see 4k video at full resolution?

    Thanks!

    4K is 4096 x 2160, the new Ultra HD consumer format has a slightly lower resolution of 3840 X 2160.

    OK but how does that effect 4K or UHD video when setting El Capitan to the default resolution of 1920x1080?

    4K video is at 4096x2160px (pixels), but the 1920x1080 refers to points, where in this case translates to 3840x2160px.

    You have the usable real estate of a typical full HD screen but each point consists of four pixels (two horizontally and two vertically). You can still view videos at up to the full resolution of your monitor.

    It refers to the interface, which will mimick a 1920x1080 display while rendering text, images, videos, and other UI elements at twice the size (vertically and horizontally) they would appear on an actual 1080p display. This is what makes Retina displays look so crisp, and means videos will take full advantage of your display in a Retina-aware player.
