been messing about with all night,defo no dead pixels and brightness is fine,i feel i got a crackin deal here considering they cost £1000,i was intending on getting the u24 but this seemed a better deal,was this a good deal or what/how do i get the best picture possible for games as it has no on screen display,only 2 buttons for the brightness or does dell fix all the colour,sharpness before it leaves the factory,other than that the picture is superb,someone mentioned custom icc profiles or is it best not to mess about with it
