灰色の画面の使い方
Calibrate brightness and color
Neutral gray is the standard backdrop for calibrating brightness and color, because it is easier on the eye than pure white or black.
Neutral photo backdrop
A mid-gray full-screen is a neutral, color-true backdrop for product photography and color-critical viewing.
Easier on the eyes
Gray at low brightness is less harsh than white for reading and late-night work while still lighting the screen area.
Check uniformity and banding
Gray reveals uneven backlight, clouding, and banding that white or black can hide — great for a quick panel inspection.
