Why Use a Grey Screen?
Banding test
Mid-grey reveals horizontal or vertical banding that white or black may hide.
Neutral reference
50% grey is a common midpoint for evaluating gamma response.
Professional presentations
Neutral grey backgrounds reduce distraction during slides or reviews.
Grey screen for gamma and uniformity
