Actually it's been available at Dell for a couple of weeks now. With a 25 ms. pixel response time, you can be assured there will be some ghosting. I would almost refer to is as smearing rather than ghosting. I had the PL191 and while it wasn't too bad, it was there.
In order to have NO ghosting/smearing, you need a pixel response time of sub 20 ms. The Planar PX171 and Hitchi and a couple of other brands have response times of 16 ms. but they are all 17" displays. There isn't a LCD display out there that I know of that is larger than 17" and has a 16 ms. response time.
Since I spend 90% of my time in Windows and play less and less games as I'm getting older, I decided I can put up with the slight smearing that takes place. While I don't watch DVD's in front of my computer (I'd rather use the living room, couch, and big-screen TV) DVD playback looks great on the PL191, so you can be sure they'll look as good if not better on the PX191. But gaming, especialy first person shooters, will experience some ghosting/smearing, albeit ever so slight. People have reported "no ghosting" on a 25 ms. LCD display, but that is simply not possible due to the technology. Their eyes just aren't catching it.
I sent the PL191 back and was going to go back to a CRT, but have since changed my mind again and I'm going to try out the PX191 in a week or two.
I don't need speakers on the display (the 1 watt speakers on the PL191 are useless for anything other than beeps and assorted Windows sounds anyway) and there are 3 things that are bringing me to try the PX191 over the PL191. Higher contrast and brightness specs., the all-around thin bezel, and the way it adjusts up and down and flips from landscape to protrait mode.
I just wish it also had the 16 ms. response time like the PX171, but I guess you can't have everything. With my luck, 3 months (or sooner) after I buy the PX191, the industry will come out with a 19" LCD that does have 16 ms. response time.
BTW...here's a link to a thread from a forum member who had the Dell and the Planar side by side and at first he claims no ghosting, but later updates it to admit that he does infact notice some.
