FWIW, here is my quick review of the 930b and vp191b. I bought both of these monitors and had them running side by side on my desk with the same images (using nvidia dualview). My last monitor was an NEC FE991sb CRT so I was pretty adament about not having any ghosting and having accurate colors - I've stayed away from LCDs due to their lack of gaming suitability in the past....
No Ghosting---or sparkling noticed by me.....
There was no ghosting on either monitor for all kinds of fast paced games. I tested them with Painkiller, Call of Duty, Doom 3 and more and neither had any noticeable (to me) ghosting. I also did not see any sparkling on surfaces that were noted in a couple of reviews-but I don't really watch movies on my computer so it's not a factor for me...as far as in games, there has been zero sparkling or ghosting on either monitor.
Samsung 930b
+very vivid colors - not sure why but reds and deep blues seemed richer than the 191b - almost to the point of looking too vivid and slightly "crayola-ish" - this looked nice but I'm not sure it was accurate color reproduction
-unable to display some colors on the spectrum while the vp191b displayed the full spectrum very well
-dark areas in games had a "purple hue" and details in the shadows were not visible (this was the biggest deciding factor for me against this monitor since the purplish colors where the blacks were supposed to be completely ruined the immersiveness for me.)
-desktop text was not as clear as the 191b and the edges of the text had color bleeding
-only physical adjustment was fore and aft pivot
-does not include dvi cable in box
+excellent interface for monitor adjustments including many presets for different activities (ie...internet use, gaming, videos...very handy)
+zero dead pixels
+$349 after rebate at a local store
vp191b (rev. 3.0 8ms)
+color seemed less vivid and rich compared to the 930b - but the colors did seem more accurately displayed than the 930b which was unable to display some colors at the ends of the spectrum
+dark areas in games were flawless and looked black, details were present in dark areas as well (this was the biggest factor for me personally)
+text is sharp and free of colors on the fringes
+excellent ability to raise, tilt, pivot and rotate to portrait mode
-interface for monitor adjustment does not have number scale so you have to guess on the settings...which kind of sucks but once adjusted is not an issue
-1 dead pixel on bottom left corner
-$429 + $10 shipping from online retailer
Both are really nice monitors, but for me, the viewsonic looked much better in games due to more accurate blacks and details in the shadows. Text on the desktop also looked much better. I'm not sure I will ever use the physical adjustments on the viewsonic, but it's nice to know they are there- including both analog and digital cables was also a nice touch. Since I bought the viewsonic online, I couldn't preview it to make sure there were no dead pixels...looks like Im stuck with the one dead pixel, but I don't even notice it at all unless I put my face next to the screen to look for it.
winner: viewsonic vp191b - compared side by side with the 930b it was the clear winner
Tom's Hardware seems to agree with my findings:

p.s. any viewsonic vp191b owners out there have any advice for the best contrast/brightness settings? Currently I'm using about 75% contrast and 55% brightness (damn you viewsonic for not putting a numbered scale on the adjustments!!!!)
