The CB270HU 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 common contrast ratio.
This LCD screen's contrast ratio (100000000:1) is in fact the best contrast ratio across all comparable spec PC screens that have been on the market for a similar time to the CB270HU.
Across similar types of LCD screen the worst contrast ratio is Mega Contrast.
We compared all the other PC displays that have a 100000000:1 dynamic contrast ratio to this PC monitor and we think because of it's better review score, the CB290C, and the V276 both from Acer or the Asus PB287 ($343.99) is also worth considering.
