The highest contrast ratio of the Samsung LS27C45KBSV is 1000:1. That's 100% less contrast ratio than a 20000000:1 PC screen, which is the most common contrast ratio. The worst contrast ratio of all LCD screens of this age and spec is Mega Contrast and the best is 100000000:1.
We compared all the other LCD screens that have a 1000:1 dynamic contrast ratio to this PC screen and we think the LG 24M45 (£115.81), and the Samsung S23B350 which has a better Rating is also worth considering.
If you are looking for a flatpanel monitor with a higher contrast ratio then you might want to consider the ZR24w (3000:1), or the ZR30w (£835.00) (3000:1) both from HP which also has a higher Rating.
