Why this tool is useful
A pure white screen is essential for testing your display maximum brightness, backlight uniformity, and color temperature accuracy. In a calibrated display, white should appear neutral without any visible blue, yellow, or pink tint across the entire screen surface. Graphic designers and print professionals use white screens before every session to verify that their monitor white point has not drifted from the target D65 daylight standard at 6500K.
