I have had my 2408 for the last week and have tried each of the color profiles, including the custom settings. Regardless of the settings, reds and greens are extremely blown out. It's as if they are neon. The only exception is with sRGB and then everything is exceptionally dull. I'm sending it back.
Well, I think that everyone has this problem, some people don't like it, some people do. It's a "feature", not a bug D) so I don't think that a replacement will be different. Maybe a firmware update will fix that - who knows. The sRGB preset is way under-saturated for everyday use though, so I recommend a custom RGB setting - all the colors bellow 80 if you're not going to calibrated the screen.
