GSDF calibration primarily ensures consistent grayscale rendering across displays, which most directly affects which image attribute?

Explanation:
GSDF calibration sets the mapping from digital gray levels to luminance so that equal gray-step changes are perceived as equal brightness differences across displays. This directly affects how bright the image appears and how well you perceive contrast between tissues, because perceptual uniformity makes transitions from light to dark consistent across monitors, improving diagnostic reliability. It does not change hardware characteristics like matrix size, pixel shape, or spatial resolution, which are determined by the display’s geometry and sampling rather than its brightness response.
