What does nativism refer to?

Answer 1

A "Native Resolution" on a monitor refers to the resolution it is meant to be run at, where the resolution usually matched to being pixel perfect <Meaning information displayed on the screen for the computer matches up to display's pixels perfectly. The computer will put out, for example, a 1280x1024 screen in which the contents of it's desktop or video stream will fit in, and the monitor is able to display this perfectly because that is what the Raster is set too.

Now CRT monitors usually had a maximum resolution it would be able to display and could do smaller resolutions by switching phase without much, if any, loss in quality. This was one of the few advantages of a CRT over and LCD, which can display lower resolution but must resort to "Interpolation" in order to do so.

Interpolation allows the LCD to display a resolution lower then it's native. Such as the monitor above with a 19 inch display and a native resolution of 1280x1024 (4:3 aspect ratio) would be able to show a computer screen at a res of 800x600, but it would look much worse then a LCD of native 800x600 resolution.

So when a monitor says "Native Resolution: 1920x1080" it means that is the resolution your computer should be set too in order to get the best quality.

Hope that helps!
