This package contains the HP Display Installer program, which automatically detects the Microsoft Operating System that is running on your computer and installs the corresponding .INF and .ICM driver files that are used to configure the 19-inch HP L1906 LCD Monitor. The setup information, or .INF file, defines monitor resources used by Microsoft Operating Systems in order to ensure monitor compatibility with the graphics card installed in your computer. The image color matching, or .ICM file, is a color data file that is used in conjunction with graphics applications to provide consistent color matching from monitor screen to printer, or from scanner to the monitor screen. The .ICM file is only activated from within the graphics applications that support this feature. NOTE: For the Microsoft Windows 2000, Microsoft Windows XP Home Edition, Microsoft Windows XP Professional Edition, Microsoft Windows XP Professional x64 Edition, Microsoft Vista Home Basic 32 and 64 Editions, Microsoft Vista Home Premium 32 and 64 Editions, Microsoft Vista Business 32 and 64 Editions, and Microsoft Vista Ultimate 32 Edition Operating Systems, Microsoft Windows Hardware Quality Labs (WHQL) certified monitor drivers are installed.
