I think we're talking apples and oranges. But 10,000:1 means for every inch of screen there is 10,000 little points of light to use. This is the resolution capability of the screen. Massive.

If you look at the dimensions of the panel in relation to the number(900) and compared to a 30 inch with "2560 x 1600 " there is no difference. It's just the native relation to have an image appear normal. If you shrink the 2880 number down, the 900 could go up! Contrary to popular belief, the 1024x768 is NOT resolution. It is SIZE. In an image, an 800x600 image does not denote the resolution. The DPI does. If you change the "600" to something, the image just stretches. Same thing with the monitor.
