The highest contrast ratio of the Acer 196W is 100000000:1. That's over five times the contrast ratio of the most common dynamic contrast ratio of 20000000:1.
A 100000000:1 dynamic contrast ratio is actually the best contrast ratio across all small monitors that are a similar age to the 196W.
The worst contrast ratio across similar types of PC monitor is Mega Contrast.
We compared this flatpanel monitor to all the other PC monitors that have a 100000000:1 dynamic contrast ratio and we think a cheaper flatpanel monitor such as the Packard Bell Viseo 193DX, and the Acer 193HQLHb or you might consider a higher scoring flatpanel monitor such as the Acer 176L are also worth considering.
