I have a U2410 and I love it. The backlight bleed isn't noticeable (to me?) unless it's an all black screen, and I never notice it in gaming.
input lag isn't noticeable in games, but that said I use a different monitor for twitch gaming, but I'm sensitive to millisecond delays in some games.
My son uses the U2410 for COD and he is better than me (this is debatable, he scores higher in public matches but one on one I think I can take him). Any input lag isn't affecting him at all. It's my main PC gaming monitor.
How many mods does it take to screw in a light bulb? "the lightbulb is technically not violating the TOS so we're powerless to do anything about it"
