Also, you need to be careful that you're comparing apples-to-apples in pixel speed. [link|http://www.dansdata.com/askdan00009.htm|Gray to gray versus black to white to black].
We've got some LCDs at work that have big "2 ms!" stickers on them and they don't look any better than our 17" Samsung [link|http://www.samsung.com/au/products/monitors/tft/710n.asp?page=Specifications|710N] with its 12 ms response time. In fact, I think they look worse.
Cheers,
