The Acer XR341CK has a maximum contrast ratio of 100000000:1. That's over twenty times the contrast ratio of a 5000000:1 flatpanel monitor, which is the most common contrast ratio.
A 100000000:1 dynamic contrast ratio is actually the best contrast ratio amongst all comparable spec flatpanel monitors that are a similar age to the XR341CK.
Amongst comparable types of PC monitor the worst contrast ratio is Mega Contrast.
We compared all the other LCD screens that have a 100000000:1 dynamic contrast ratio to this flatpanel monitor and we think because of it's better review score, the BX320HK, and the B326HKA both from Acer or the Asus PB279 ($499.00) is also worth considering.
