I posted this on the LightBoost thread, but I thought I'd share it here too as it's relevant. I have had my three FG2421's for nearly a week now and boy my eyes have never been loved so much. The picture quality, clarity and depth of colours are just amazing. Gaming wise the motion blur tech is just stunning. All three of mine were manufactured in Japan on 02/10/13. Which means that we're seeing these Japanese made screens in the EU as well now. All have no back bleed, hatching or ghosting as yet, so it looks like the have improved their quality control and initial teething problems too!!!
Also I am not getting any input lag at all, they seem just as responsive as my old Asus VE278Q every was. So I just dunno what all this input lag fuss is about? But to get the best out of these bad boys, you must have them all connected via the Display Port outlet or a DUAL DVI cable. If not then the advanced features do not work and the screen functions as a 60Htz panel. Which may explain why other users have been experiencing problems with them. They may be a bit more expensive than other monitors, but just like everything in life, quality does not come cheap. The difference between TN and VA panels is like looking at your current screen through dark sunglasses, then removing them. It's as noticeable as that. So the moral of the story is owning the best brings added satisfaction to the users experience!!!
