The Edge10 ET185a has a maximum contrast ratio of 10000:1. That's 100% less contrast ratio than the most frequently found dynamic contrast ratio of 20000000:1. The contrast ratio of all LCD screens of a comparable spec and age to the ET185a ranges from Mega Contrast (worst) to 100000000:1 (best).
We compared all the other flatpanel monitors that have a 10000:1 dynamic contrast ratio to this PC display and we think cheaper LCD screens such as the ES195c (£78.72), the EF185a (£79.99), and the ES220D Slim (£78.55) all from Edge10 is also worth considering.
If the contrast ratio of this LCD screen is not high enough for you then you might also want to look at the Viewsonic VA2046 (£93.35) (1000000:1) which is also higher rated.
