These monitors, like LG's last line, are some of the few with a real 2ms response time.
Please take a look at the Viewsonic PC linked to. Note that the "2ms response time" has (GTG), or Grey-to-Grey next to it. In other words, it's a lie. There are no Viewsonic monitors with 2ms response times. Response time is not a regulated measurement and thus can be abused by manufacturers who choose to do so, and one of those manufacturers is Viewsonic.
PC eye has proven that he's unable or unwilling to comprehend this.
