The Acer 296CL 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.
A 100000000:1 dynamic contrast ratio is actually the best contrast ratio across all medium monitors that have been on the market for around the same time as the 296CL.
A Mega Contrast dynamic contrast ratio is the worst contrast ratio amongst similar types of LCD screen.
We compared this LCD screen to all the other flatpanel monitors that have a 100000000:1 dynamic contrast ratio and we think the H276HL ($199.90), and the 276HUL both from Acer which has a better Rating is also worth considering.
