The highest contrast ratio of the Acer 202HQL is 100000000:1. That's over twenty times the contrast ratio of a 5000000:1 PC monitor, which is the most common contrast ratio.
A 100000000:1 dynamic contrast ratio is in fact the best contrast ratio amongst all comparable spec LCD screens that were released more than a year ago.
