The AOC E2262 has a maximum contrast ratio of 50000000:1. That's over two times the contrast ratio of the most frequently found dynamic contrast ratio of 20000000:1. Across all PC displays of this type and age the best contrast ratio is 100000000:1 and the worst is Mega Contrast.
It may also be worth also looking at one of the alternative PC screens that have a 50000000:1 dynamic contrast ratio currently available including because of it's better review score, the AOC i2476 (£104.99).
If the contrast ratio of this medium monitor is too low for you then you might also want to consider the VG248QE (£185.99) (80000000:1), the MX239H (£166.37) (80000000:1), or the PA248QJ (£400.84) (80000000:1) all from Asus which also has a higher Rating.
