This Iiyama does not support Lightboost. It may have a low input lag, it'll never overcome fixed LCD turnover timings.http://www.blurbusters.com/zero-motion-blur/lightboost/
You can apply a registry hack or simple trick to enable Lightboost in non-3D environments. This eliminates the normal physical LCD pixel cooldown, which allows you to experiene near CRT refresh speeds.
Other monitors may claim to support 1ms timings, I'd like to see some high speed videos that prove this.
*update* forgot my submission: Asus VG278HE. Lightning fast and supports Lightboost.
