However, it is less than the HP LP2408zx, which has the largest range of any monitor in our office. We should point out that were not offering this as an alternative buying choice but a technical demonstration of whats possible (because it requires a 10-bit graphics card which Apple doesnt currently support). So, the new display has a larger range than the old model so it should have more accurate colour, right? Wrong. When we held the PressMatch Reference Print next to the screen we found extreme variations on the glossy display. The model that we were looking at had slightly rouge lips on the photograph that pretty much matched exactly on the older LCD Cinema Display; but on the new glossy LED Cinema Display her lips looked unnaturally red. They were simply different colours. Theres no denying that the LED Cinema Display produces beautifully vibrant images, the problem is they just dont look like anything that comes out of the printer. Even after careful colour calibration."
