You see TN panel are in reality much more than 2ms. The reason for this, is that TN panels can only output 6-bit colors (262 144 colors), the way it does to output the missing colors to get 8-bit (16 777 216 colors), it uses a technique of take the 2 closet colors it can produce, and switch between them like no tomorrow, to trick your eye that it's the correct color... hence the 2ms response rate (as manufactures don't calculate white to black response time, but rather any gray they want to another gray they want). Now in a game.. pictures moves.... soo you move a color which switchs between thhem... it will look like about 6-8ms response rate... A IPS panel is true 8-bit panel to start with, so the problem in trying to trick your eyes with the missing colors is simply not there, especially that nearly all software, games, and most digital cameras are all designed to be used with an 8-bit colors. A professional will use a 10-bit or more panel, which is important in magazines/posters, professional photographs and so on... and if that is the case, the U2410 can do it thanks to it's 12-bit look up table (using the same technique as in TN panel for the missing colors.. UNLESS you use Adobe RGB or sRGB color profile in the monitor). In result, the image won't be super color accurate, but at least it won't be too bad, and this explains why this monitor is fantastic for non-real professionals who requires all these 10-bit+ colors.
