The Viewsonic VX2880 has a maximum contrast ratio of 50000000:1. That's over two times the contrast ratio of a 20000000:1 PC screen, which is the most frequently found contrast ratio. The contrast ratio of all PC monitors of this type and age ranges from Mega Contrast to 100000000:1.
We compared this flatpanel monitor to all the other flatpanel monitors that have a 50000000:1 dynamic contrast ratio and we think the AOC i2476 which has a better Rating is also worth considering.
If you want a PC screen with a higher contrast ratio then you might also want to consider the VG248QE ($213.99) (80000000:1), the MX239H ($147.99) (80000000:1), or the PA248QJ (80000000:1) all from Asus which also has a higher rating.
