The Acer 223HQ has a maximum contrast ratio of 100000000:1. That's over five times the contrast ratio of a 20000000:1 PC monitor, which is the most frequently found contrast ratio.
This PC monitor's contrast ratio (100000000:1) is in fact the best contrast ratio amongst all LCD screens of this type and age.
A Mega Contrast dynamic contrast ratio is the worst contrast ratio amongst similar types of PC monitor.
We compared all the other PC monitors that have a 100000000:1 dynamic contrast ratio to this PC screen and we think the Asus VN279 (£239.14) which has a better Rating; or the Acer S240HL (£66.97) which is cheaper are also worth considering.
