Which monitor calibration setting is most directly involved in ensuring consistent brightness across the display?

• A. Screen resolution
• B. Bit depth
• C. Pixel density
• D. Grayscale gamma adjustment

Answer: (D)

Grayscale gamma adjustment directly controls how input brightness values map to on‑screen luminance. The gamma curve determines how dark and midtone values are translated into light, so tuning it aligns the perceived brightness across the gray scale. When gamma is set correctly, a given input level produces a consistent brightness feel from shadows through midtones to highlights, helping the entire display look uniformly bright. If gamma is off, some areas can appear noticeably brighter or darker despite the same input, which breaks brightness uniformity. Screen resolution affects sharpness and pixel count, not how bright the image appears. Bit depth influences color precision, not the brightness mapping. Pixel density changes how crisp the image looks, not the luminance response.
