It should be made clear that dynamic contrast mode is suitable only for movies and, perhaps, for games, but gamers often prefer to increase brightness in dark scenes for an easier orientation in the surroundings rather than to lower it. For ordinary work this mode is not just useless, but often irritating.

A)  For LCD monitors with a real response time of less than 10 milliseconds, the further reduction of the response time brings a smaller effect than expected because the persistence of human vision becomes a factor to be accounted for. In CRT monitors the black period between the frames gives the retina enough time to "forget" the previous frame, but there is no such period in classic LCD monitors - the frames are following each other continuously. Thus, the further attempts of the manufacturers to increase the speed of LCD monitors will be about how to deal with the persistence of vision effect rather than about how to lower the specified response more. By the way, this problem concerns not only LCD monitors but also any other active-matrix technology in which the pixel is alight continuously.

B)  The most promising technology at the moment is the short-term turning off of the backlight lamps as is implemented in the BenQ FP241WZ. It is rather simple to implement (the only downside is the necessity to use a large number and a certain configuration of backlight lamps, but it's a solvable problem for monitors with long screen diagonals). It is suitable for any type of the matrix and doesn't have serious flaws. Perhaps the refresh rate of the new monitors will have to be increased to 75-85Hz, but the manufacturers may solve the problem of flickering (noticeable on the above-mentioned FP241WZ model) in other ways, so we should wait for other models with backlight blanking to appear.
