The VX2363SMHL has a maximum contrast ratio of 50000000:1. That's over ten times the contrast ratio of the most common dynamic contrast ratio of 5000000:1. LCD screens of this spec and age dynamic contrast ratios range from Mega Contrast to 100000000:1.
We think you might also be interested in some of the alternative PC monitors that have a 50000000:1 dynamic contrast ratio currently available including the I2360PQ, or the I2260PWHU both from AOC which is cheaper; or the Viewsonic VX2263SMHL which has a better Rating.
If you would prefer a flatpanel monitor with a higher contrast ratio then you might also want to look at the Asus VS278H (80000000:1 and cheaper).
