6ms TN or IPS...probably no ghosting. 6ms PVA...you might see some ghosting, although you'll also see the best contrast available in an LCD, and a great picture too as long as you don't move your head in either direction or focus too hard on dark areas. Regardless, IMO, PVAs look much better than TNs even if they ghost.
You have to make choices with an LCD. After owning multiple models by multiple manufacturers, I've come to the firm conclusion that the least painful option is an IPS. So from now on, I'll start there, and then worry about response time and other stats.
