The G227HQL has a maximum contrast ratio of 100000000:1. That's over twenty times the contrast ratio of the most common dynamic contrast ratio of 5000000:1.
This PC monitor's contrast ratio (100000000:1) is actually the best contrast ratio across all medium monitors that were released more than a year ago.
A Mega Contrast dynamic contrast ratio is the worst contrast ratio across similar types of PC monitor.
We think you might also be interested in some of the other PC displays that have a 100000000:1 dynamic contrast ratio currently available including the G247HYL, the 42HQL (£117.23), or the K212HQL (£86.00) all from Acer which is cheaper.
