From the website: Designed for calibrating and profiling all types of monitors — LCD and CRT. Each individual package includes a huey measurement device (emission only colorimeter) with ambient measurement capabilities, and software for monitor calibration.
From the website: huey corrects the color on your monitor so photos and designs print more accurately, game graphics are more intense and movies are more true-to-life. Easy-to-use right out of the box, huey adapts your monitor for changing room lighting and applies your personal preferences for viewing accurate color all of the time.
