Probably need to re-calibrate to get the color same as the U2410 or accurate to pro graphics level.
Factory calibrate looks blueish, quite obvious from the picture above.

For the 24", this is probably the first to get USB3 hub, but Dell release the USB3 hub on its U2713HM first, nice upgrade for anyone looking at 24".

Any chance of calibrated result and stuff like that? Maybe some input lag test? Against its rival U2410 that is (U2410 has reasonable input lag ~20ms++).
