Native resolution: What is it?
“Native resolution” refers to how many pixels there are in the screen itself. Resolution is expressed as two numbers – the horizontal pixel count and the vertical pixel count, 640×480, for example. The horizontal number is usually larger than the vertical. Total pixel count is the product of the two numbers — 640×480 = 307,200 pixels, for example. A pixel is a picture element – one of many tiny dots which make up the picture. It strictly is used only for fixed-pixel cameras (CCD, CMOS) and displays (LCD, plasma, DLP, LCOS). The expression “native resolution” is technically incorrect for describing picture-tubes (CRTs). Picture-tubes are analog displays. They use a different figure called “dot pitch” to describe the physical design, which cannot be directly compared to pixel count. Also see FAQ B-2. The native resolution of current TVs is generally classified as SD, ED and HD. • HD (high-definition, digital) TVs have higher native resolutions – 1280×720 and up. • ED (enhanced-definitio
