The HL226HPB has a maximum contrast ratio of 80000000:1. That's over four times the contrast ratio of a 20000000:1 PC display, which is the most frequently found contrast ratio. The contrast ratio of all medium monitors that came out around the same time as the HL226HPB ranges from Mega Contrast (worst) to 100000000:1 (best).
We compared all the other PC monitors that have an 80000000:1 dynamic contrast ratio to this PC monitor and we think because of it's better review score, the Asus VE228 ($90.99), the Hanns.G HS221, and the Hannspree HS221HPB is also worth considering.
LCD screens with a higher contrast ratio that might be worth looking at include the Acer 222HQL (100000000:1 and cheaper) or the Acer V226 ($74.99) (100000000:1 and higher rated).
