The Acer G237HL has a maximum contrast ratio of 100000000:1. That's over five times the contrast ratio of the most common dynamic contrast ratio of 20000000:1.
This flatpanel monitor's contrast ratio (100000000:1) is actually the best contrast ratio amongst all medium monitors that have been on the market for more than two years.
The worst contrast ratio across comparable types of flatpanel monitor is Mega Contrast.
We compared this LCD screen to all the other PC monitors that have a 100000000:1 dynamic contrast ratio and we think the Asus VN279 (£239.14) which has a better Rating; or the Acer 226HQ (£90.58) which is cheaper are also worth considering.
