Gray Screen — Neutral Fullscreen Gray
Gray fullscreen sits between black and white, exposing banding, vignetting, and tint shifts that pure extremes hide. It is especially useful on OLED when evaluating near-black gray steps.
Use mid-gray during monitor reviews to compare units side by side with the same browser fill, understanding that absolute luminance still depends on brightness setting.
Fillhex gray is balanced RGB gray for a neutral reference, with fullscreen on F or double-click.
Why gray reveals banding
Gradients in UI and video often fail first in shadow regions. A flat gray field makes 8-bit panel banding and poor GPU dithering obvious as horizontal or vertical stripes.
OLED near-black evaluation
OLED black crush and raised blacks show on dark gray better than on pure black. Pair gray tests with oled-burn-in-test guidance for long-term habits.
Uniformity across the panel
IPS glow appears as corners brightening on gray. VA may show clouding; document with photos for returns within policy windows.
Calibration workflows
Gray is a quick sanity check before hardware calibrators run, not a replacement for ICC profiles.
Compare with white and black
Cycle gray, white, and black screen pages to bracket your panel behavior in one session.
Creative uses
Neutral gray fullscreen can serve as a balanced backdrop for message-display when colored slides feel distracting.
