The Acer 272HL has a maximum contrast ratio of 100000000:1. That's over five times the contrast ratio of the most frequently found dynamic contrast ratio of 20000000:1.
A 100000000:1 dynamic contrast ratio is in fact the best contrast ratio across all comparable spec PC screens that have been available for a similar time to the 272HL.

We compared all the other flatpanel monitors that have a 100000000:1 dynamic contrast ratio to this PC screen and we think the Acer B243 ($428.92), the Packard Bell Viseo 243D, and the LG 23EA63 which has a better Rating is also worth considering.
