The Acer XF270HU has a maximum contrast ratio of 100000000:1. That's over twenty times the contrast ratio of the most frequently found dynamic contrast ratio of 5000000:1.
A 100000000:1 dynamic contrast ratio is actually the best contrast ratio across all PC screens of a comparable type and age to the XF270HU.
Across similar types of flatpanel monitor the worst contrast ratio is Mega Contrast.
We compared this flatpanel monitor to all the other PC screens that have a 100000000:1 dynamic contrast ratio and we think because of it's better review score, the MG279Q ($392.99), and the MG278Q ($417.99) both from Asus or the Acer XF270H is also worth considering.
