Color Gamut and Color Space Coverage
The LP2480zx monitor uses an LED-backlit LCD module that provides an extremely wide color gamut.
This gamut was chosen to enclose a number of color spaces as defined by various standard output
device specifications, which (along with other color-management features in this product’s electronics)
permits the monitor to accurately emulate display devices conforming to these standards. The nominal
native primary set, white point, and gamma of the LP2480zx, and those of the various supported
standards, are provided in the table below:

† The Digital Cinema/SMPTE-431-2 reference projector gamut is not fully enclosed by the LP2480zx’s native gamut; when set
to the DCI preset, the monitor will provide as accurate an emulation of this space as possible within its available gamut. The
difference is primarily along the red-green edge of the DCI gamut, as the DCI red and green primaries are slightly outside the
LP2480zx gamut. See the diagram below.
