The highest contrast ratio of the VX2770Smh is 30000000:1. That's 50% more contrast ratio than a 20000000:1 PC screen, which is the most frequently found contrast ratio. The contrast ratio of all PC monitors of this age and type ranges from Mega Contrast (worst) to 100000000:1 (best).
We compared all the other flatpanel monitors that have a 30000000:1 dynamic contrast ratio to this PC monitor and we think because of it's better review score, the Philips 221V2 is also worth considering.
If the contrast ratio of this PC screen is too low for you then you might want to look at the i2769 (£167.84) (50000000:1), or the Q2963PM (£299.99) (50000000:1) both from AOC which also has a higher Rating.
