The Asus VS238 has a maximum contrast ratio of 80000000:1. That's over four times the contrast ratio of the most frequently found dynamic contrast ratio of 20000000:1. The contrast ratio of all LCD screens that came out around the same time as the VS238 ranges from Mega Contrast (worst) to 100000000:1 (best).
We compared this PC display to all the other PC screens that have an 80000000:1 dynamic contrast ratio and we think the Hanns.G HS241 (£138.17) which is cheaper is also worth considering.
If the contrast ratio of this LCD screen is too low for you then you might want to look at the V236HL (£124.74) (100000000:1), or the B236HL (£139.98) (100000000:1) both from Acer or the Asus VN279 (£239.14) (100000000:1) which also has a higher rating.
