For Screen Cleaning: The white background makes dust, fingerprints, and smudges highly visible so you can clean them effectively.
For Lighting: Position your device to face your subject for soft, even lighting during video calls or photography.
For Eye Comfort: Use warm white or off-white variations for extended viewing periods.
For Calibration: Compare different white variations to understand your monitor's color temperature settings. Also check your display refresh rate and screen resolution.
