    I don't really get the purpose of this message.
    (Besides the typo you made 100:1 vs 1000:1)

    Those numbers don't mean much. I've have two 1080p screens, both over 1500:1 contrast ratio across the entire brightness range. This is also in line with numbers in notebookcheck's review.

    True they don't mean much when you go over 1000:1, but they mean a whole heck of a lot when you start creeping below 400:1. It usually means your blacks are really grey.

    Black level and contrast are not the same thing. You could have near-perfect blacks and still have a 400:1 contrast ratio, it would just mean that the whites aren't very bright. Contrast purely talks about the biggest difference between the whitest white and the blackest black your screen can show (at a given brightness level of your screen).
