The highest contrast ratio of the AOC i2367 is 50000000:1. That's over two times the contrast ratio of a 20000000:1 PC screen, which is the most frequently found contrast ratio. LCD screens of this age and type dynamic contrast ratios range from Mega Contrast (worst) to 100000000:1 (best).
There are a number of alternative PC displays that have a 50000000:1 dynamic contrast ratio currently available that you might want to consider including the Viewsonic VX2263, or the AOC E2462 which is cheaper.
If the contrast ratio of this PC display is not high enough for you then you might want to consider the MX239H ($147.99) (80000000:1), or the VN247 ($189.00) (80000000:1) both from Asus or the AOC G2460 ($249.99) (80000000:1) which also has a higher Rating.
