But then agian I keep hearing about how this is not possible yet so...

It uses an S-PVA panel with Overvolting tech.

Isn't the Dell 2405 8bit/8ms?

It has a 24 inch 12 ms (g2g) 8-bit PVA (Samsung LTM240M1-L01) panel. They inflate the specs most likely. I don't think the 2405FPW uses any sort of Overdrive.

The VP930B features 8ms (grey to grey) and 20ms (black-white-black). It is just advertised as 8ms short. If you read user reviews they say its got great picture and features but lacks when gaming. I was thinking about buying it around christmas but after reading that it ghosts im not sure anymore.

Yea when I noticed that, I was confused because I thought it was much harder to achieve good grey to grey timings so when I saw that it got 20MS Off and on, I was like WTF? I heard that most displays that get like 8MS off to on, the grey to grey would be significantly higher.

To answer your question:

The ViewSonic 930B uses a 8-bit "Premium" MVA panel (I think PVA are Samsung only and ViewSonic typically uses AU)

Recently, many companies have taken to adding "Overdrive" to MVA and PVA panels. The goal was to have a faster response time while retaining the better blacks, better viewing angles, etc.

Previously PVA/MVA panel types had maxed out at around 16 ms response times in the ISO specification. ISO referes to moving from only extremes (Ie White/Black). In this situation, Grey to Grey was slower because panels change faster as the voltage level increases and for LCD voltage level is proportional to the change in colors requested.

In the Overdrive situation, the panel automatically adds more voltage to the each color change request. This lets the transition from grey to grey go faster. Especially since the producers measure the response time the first time the pixel achieves the desired color. This is important because the additional voltage while speeding up the color change, can make the color actually "overshot" the mark a bit and require time to return to the correct color level.

In the end, this means that a Panel with Overdrive shouldn't be faster in the ISO specification, because this was already using the maximum voltage for the panel. However, Grey to Grey is significatnly reduced (and thus why they use it). On a positive note, while 8ms might be a total lie in comparison to actual operation, the 20 ms is very accurate (given how viewsonics 8-bit panels have tested in the past) and the true grey to grey transitions are most likely less than 20ms... which is pretty good all things considered.

Yes its a pretty good monitor but still not suited for a heavy gamer.....Unless they wish to sacrifice response time for better quality.
