Responsiveness, Input Lag and Ghosting
I don’t have special equipment for instrumental measurement of the monitor response time. Neither do most of test magazines.
Bulky Internet articles would tell you much about such a phenomenon as “persistence of vision” and so on.
So even instrumental measurements with accordance to industry standards are applicable to a certain extent only. Our subjective impression means more.
My subjective impression says that the Dell 2408 is very good in this aspect. Moving objects are as clear and sharp as one can expect from a large LCD monitor. Nothing major. Subjectively, in the area of responsiveness the Dell is not any worse that the reference monitor.
