The Asus VX248 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 common contrast ratio. The best contrast ratio of all PC screens of a similar type and age to the VX248 is 100000000:1 and the worst is Mega Contrast.
We compared all the other PC displays that have an 80000000:1 dynamic contrast ratio to this flatpanel monitor and we think the VX229, and the VS238 ($110.99) both from Asus which is cheaper; or the Asus VS24 ($149.00) which has a better Rating are also worth considering.
If you want a PC screen with a higher contrast ratio then you might also want to consider the Packard Bell Viseo 243D (100000000:1), or the LG 23EA63 (100000000:1) which is also cheaper.
