The faster the true response time is, the worse the color representation is. It is the very nature of LCD's which cause that.
It is all about trade-offs. Most, if not all, people do not care about accurate color representation, but I thought I would bring it up anyway.
You would have top spend about $5,000.00 to get an LCD monitor that could present color accuracies near the 99% range and it would ghost all over the place.
And please do not follow my post with, "my LCD produces colors just fine". You really do not know how bad it is, until you have it professionally calibrated.
I am not expressing an opinion here. It is just some simple facts.
