Response time
The number not often quoted is the time it takes a pixel to switch from one color to another. Its quoted in milliseconds and is often broken into its 2 parts the rise & fall (i.e.: a 10ms rise & 20ms fall would be added together to get a 30ms response time). Response time has dropped dramatically since LCDs hit mainstream. My old IBM Thinkpad 600E (manufactured in early 2000) has a response time of 50ms. When I play a fast moving game on it, the pixels can not keep up and there is a little ghosting that happens. The VE500 has a response time of 30ms, which seems to be quite good. Its been noted that a 25ms response time yields 25 pictures per second which the human eye perceives to be full-motion. To be honest, I haven't noticed any ghosting on the VE500 at all, despite playing some games that really tax the system.
