The highest contrast ratio of the Viewsonic VG2433 is 50000000:1. That's over two times the contrast ratio of a 20000000:1 flatpanel monitor, which is the most common contrast ratio. The best contrast ratio of all flatpanel monitors that were launched more than two years ago is 100000000:1 and the worst is Mega Contrast.
We compared all the other flatpanel monitors that have a 50000000:1 dynamic contrast ratio to this flatpanel monitor and we think the I2369, and the I2473 both from AOC or the Asus PB238 ($187.99) which has a better Rating is also worth considering.
If the contrast ratio of this medium monitor is too low for you then you might want to look at the Asus VG248QE ($213.99) (80000000:1 and higher rated), or the AOC G2460 ($249.99) (80000000:1 and higher rated).
