The Information File
The .INF file defines monitor resources used by Microsoft Windows operating systems to ensure monitor
compatibility with the computer’s graphics adapter.
This monitor is Microsoft Windows Plug and Play compatible and the monitor will work correctly without
installing the .INF file. Monitor Plug and Play compatibility requires that the computer’s graphic card is
VESA DDC2–compliant and that the monitor connects directly to the graphics card. Plug and Play does
not work through separate BNC type connectors or through distribution buffers/boxes.
The Image Color Matching File
The .ICM files are data files that are used in conjunction with graphics programs to provide consistent
color matching from monitor screen to printer, or from scanner to monitor screen. This file is activated
from within graphics programs that support this feature.
NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC)
Profile Format specification.
