The highest contrast ratio of the Acer G196 is 100000000:1. That's over five times the contrast ratio of a 20000000:1 flatpanel monitor, which is the most common contrast ratio.
A 100000000:1 dynamic contrast ratio is in fact the best contrast ratio across all LCD screens that are a comparable age to the G196.
The worst contrast ratio amongst similar types of LCD screen is Mega Contrast.
We compared all the other flatpanel monitors that have a 100000000:1 dynamic contrast ratio to this LCD screen and we think the 176L, and the 196L ($124.99) both from Acer which has a better Rating is also worth considering.
