2 Using the display Software and utilities The disc that comes with the display contains files you can install on the computer. ● an .INF (Information) file ● ICM (Image Color Matching) files (one for each calibrated color space) ● USB Software Development Kit (SDK) for Linux, Windows, and Mac ● sample StudioCal XML scripts NOTE: The items listed above can be downloaded from the HP display support Web site. For more information, go to Downloading from the Internet on page 18. The information file The .INF file defines display resources used by Microsoft Windows operating systems to ensure display compatibility with the computer's graphics adapter. This display is Microsoft Windows Plug and Play-compatible. It works correctly without installing the .INF file. Plug and Play compatibility requires that the computer's graphic card is VESA DDC2-compliant and that the display connects directly to the graphics card. The image color matching files The ICM files are data files that describe the colorimetry of the display. In the case of calibrated displays, they describe the colorimetry of a given color preset. This information includes the preset's calibrated color gamut, grayscale response, and white point. These files are used by the operating system's color management engine-as well as the color management engine built into specialized photography, video, and graphic arts applications-to ensure that colors on-screen are rendered correctly and will be displayed accurately when viewed on the display. While not all programs support the use of these files, HP strongly recommends that you always select or enable the ICM file matching the active color preset to ensure the best image reproduction. NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC) Profile Format specification. Software and utilities 17
