DESC: 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. 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.
