The display colour response is not corrected by making adjustments to the display itself but by applying corrections to the graphics card. Usually these corrections are loaded by a profile loader applet loading the correction values from the display profile into the colour Look Up Table (LUT) on the graphics card at boot time. These corrections are therefore global, affecting everything displayed, following boot up.

Most colour profiling applications are supplied with a profile loader applet which is installed during installation of the main program. A short cut to the profile loader is placed in the Start folder and is therefore called during operating system boot. Under Windows Vista these can be found via Start > All Programs and opening the Startup folder. Any profile loaders should be listed here.

If several applications with colour management that support profile boot loadŽers are installed on the same PC there can be some confusion. The LUT will eventually be loaded by whichever loader and profile is loaded last in the boot sequence and this may not be the desired profile. Users should manually edit the Start folder and remove all loader short cuts except to the desired loader. Ideally this should be for a hardware display calibrator and its associated software.
